• Page 14: Gps Coordinates

  Projection Mode Survey Pro has two different modes for calculating local northing and easting from GPS measurements: Ground – TDS Localization, and Mapping Plane. Survey Pro has two different modes for calculating the vertical coordinate from GPS measured heights: Localization (+Geoid) and Ellipsoid Heights.

• Page 15
  Survey Methods adjustment is a 2D similarity transformation that shifts, scales, and rotates the default map projection’s locations (y,x) into your local coordinates (N,E). In Ground — TDS Localization mode, when you measure a distance with an EDM, the distance measured on the ground is 1:1 with the distance on the local coordinate grid.
• Page 16
  A coordinate system is un-initialized when you have no zone record set. In Ground – TDS Localization mode, this means that you have not yet configured the first RTK base position in Survey Pro. In Mapping Plane mode, this means you have not yet selected a zone record from the coordinate system database.

• Page 17: Coordinate System Database

  Coordinate System Database Survey Pro uses a Coordinate System Database file (*.CSD) to store the map projection and datum transformation parameters for many different coordinate systems around the world. Also, horizontal and vertical localization adjustments can be stored as site records in the database.

• Page 19: Real Time Kinematic (Rtk)

  Real Time Kinematic (RTK) RTK data collection uses differential GPS corrections broadcast by a base receiver to solve for coordinates at a rover receiver in real time. This section describes how to start a GPS survey and how to use GPS data collection and stake out.

• Page 83: Horizontal Coordinate Systems

  GPS Coordinates Horizontal Coordinate Systems Survey projects use horizontal coordinates on either a local plane or a map projection. For small projects, you can assume a simple flat earth plane and calculate coordinates directly with measured distances. Use Ground — TDS Localization mode for this procedure. For large projects, a mapping plane is used to accurately represent the curved surface of the earth on a flat plane and conventionally measured distances need to be scaled to the mapping plane grid.

  GPS Coordinates • Stereographic The Stereographic projection results from projecting an ellipsoid onto a plane. Directions are true from the center point and distortions in scale, area and shape increase uniformly away from the central point. The stereographic projection is azimuthal. Because the scale is distorted somewhat uniformly in all directions, stereographic map projections are a good representation of a surveyor’s typical flat earth ground coordinate system.

You shall be responsible for all taxes, withholdings, duties and levies arising from the order (excluding taxes based on the net income of the Licensor Supplier). Any late payments shall be subject to a service charge equal to 1.5% per month of the amount due or the maximum amount allowed by law, whichever is less.

5.Term of Agreement

5.1.Term. This Agreement is effective as of the Effective Date and expires at such time as all license and service subscriptions hereunder have expired in accordance with their own terms (the “Term”). Either party may terminate this Agreement (including all related Order Forms) if the other party: (a) fails to cure any material breach of this Agreement within thirty (30) days after written notice of such breach; (b) ceases operation without a successor; or (c) seeks protection under any bankruptcy, receivership, trust deed, creditors arrangement, composition or comparable proceeding, or if any such proceeding is instituted against such party (and not dismissed within sixty (60) days)). If you have entered into a separate written agreement with Licensor which governs the Software and that agreement is terminated, then this Agreement automatically terminates and you shall no longer have any right to use the Software. Termination is not an exclusive remedy and the exercise by either party of any remedy under this Agreement will be without prejudice to any other remedies it may have under this Agreement, by law, or otherwise. For clarity, even if you have entered into an Order Form with a Licensor distributor or reseller, Licensor is a third party beneficiary to that Order Form and has the right to terminate this Agreement as set forth in this Section 5 (Term of Agreement).

5.2.Termination. Upon any expiration or termination of this Agreement, you shall cease any and all use of any Software and Evaluation Software and destroy all copies thereof and so certify to Licensor in writing.

8.Professional Services.

The Licensor Supplier shall provide the number of person-days, if any, of professional consulting services (“Professional Services”) purchased in the applicable Order Form and related Statement of Work. If Licensor is providing Professional Services, unless agreed in a separate written agreement all Professional Services shall be provided pursuant to Licensor’s standard service terms which are available upon request from Licensor. If your Order Form is with a Licensor Supplier other than Licensor, that party (and not Licensor) is solely responsible for providing Professional Services and Licensor has no liability related to such services.

9.Limitation of Remedies and Damages.

9.1.NEITHER LICENSOR NOR LICENSOR’S SUPPLIERS SHALL BE LIABLE FOR ANY LOSS OF USE, LOST DATA, FAILURE OF SECURITY MECHANISMS, INTERRUPTION OF BUSINESS, OR ANY INDIRECT, SPECIAL, INCIDENTAL, OR CONSEQUENTIAL DAMAGES OF ANY KIND (INCLUDING LOST PROFITS), REGARDLESS OF THE FORM OF ACTION, WHETHER IN CONTRACT, TORT (INCLUDING NEGLIGENCE), STRICT LIABILITY OR OTHERWISE, EVEN IF INFORMED OF THE POSSIBILITY OF SUCH DAMAGES IN ADVANCE.

9.2.NOTWITHSTANDING ANY OTHER PROVISION OF THIS AGREEMENT, LICENSOR AND ITS SUPPLIERS’ ENTIRE LIABILITY TO YOU UNDER THIS AGREEMENT SHALL NOT EXCEED THE AMOUNT ACTUALLY PAID BY YOU TO LICENSOR UNDER THIS AGREEMENT.

Scope This manual will guide you through your first steps using Survey Pro. Whether you are using optical or GNSS equipment, you will find here key instructions and explanations for a successful start.

If you are new to Survey Pro, reading the first three sections will help you understand the organization and workflow of the software.

The rest of the guide is dedicated to helping you start your field work.

•Station setup is an essential step when surveying with an optical instrument: this guide discusses the Known Point and Resection routines, followed by a short description of a few standard surveying procedures (traverse/sideshot, repetition).

•Choosing the right coordinate system before starting a job with GNSS is also an essential step: the guide will take you through the different possible scenarios, followed by a short description of standard data collection procedures.

•Stakeout routines are functions common to optical and GNSS surveying. These are introduced in 7. Stakeout Routines on page 50.

•The last section provides instructions specific to Survey Pro running on Nikon Nivo and Spectra Precision FOCUS total stations.

From your first successful experience with Survey Pro, based on the information provided in this guide, you will be able to extend your knowledge of the software to its many other functions, relying on your own experience as a surveyor and referring to the on-line Help whenever necessary.

Conventions Used The following conventions are used:

•Text strings in bold font represent the names of software items such as fields, buttons, check boxes, tabs, messages, screens, menus, etc.

•The symbol “>” is placed between menus, tabs and/or buttons to indicate that you have to tap on these parts successively in that order.

•When referring to both optical instruments and GNSS receivers, the term “instruments” will be used to encompass the two types of equipment.

The following acronyms and abbreviations are used:

•BS: Backsight

•EDM: Electronic Distance Meter

•NEE: Northing, Easting, Elevation (grid coordinates)

•HA: Horizontal Angle

•LLH: Latitude, Longitude, Height (geodetic coordinates)

•PPM: Part Per Million

•SD: Slope Distance

•SS: Side Shot

•ZA: Zenith Angle

The following conventions are used when inputting or outputting angles:

•Azimuths, latitudes, longitudes are entered in degrees-minutes-seconds format and are represented as DD.MMSSsss, where:

–DD: One or more digits representing the degrees

–MM: Two digits representing the minutes

–SS: Two digits representing the seconds

–sss: Zero or more digits representing the decimal fraction part of the seconds.

E.g.: 212.0805 would indicate 212 degrees, 8 minutes and 5 seconds.

•Bearings can be entered in either of the following formats:

–S32.0805W to indicate South 32 degrees, 8 minutes, 5 seconds West.

–3 32.0805 to indicate 32 degrees, 8 minutes, 5 seconds in quadrant 3.

When a field accepts a time for its input, the time is entered in hours-minutes- seconds format, which is represented as HH.MMSSsss, where:

–HH: One or more digits representing the hours

–MM: Two digits representing the minutes

–SS: Two digits representing the seconds

–sss: Zero or more digits representing the decimal fraction part of the seconds.

The command bar is that portion of the Survey Pro screen that remains always displayed whether the Home screen, the Main Menu or one of its submenus is displayed. The command bar contains the following items:

• Map View [1]: This button will access the map view of the current job when

[1]it is tapped. The map view is available from many screens (see Map View on page 8).

[2]• Instrument Used [2]: The Instrument icon indicates the mode (optical or

GNSS) that the software is in, and the type of instrument the software is

[3]currently associated with.

[4]

This icon is also used to change the instrument and perform additional settings on this instrument. See 4. Connecting Survey Pro to an Instrument on page 15.

How to Customize the Home Screen

Adding a Function

This is a three-step procedure:

•Go to the Main Menu, then to the submenu containing the function you would like to add to the Home screen.

•Tap and hold the corresponding function item and select Add to Home. Survey Pro then shows the Home screen with all the possible free locations for the new function, all represented as unnamed icons. Note at this point that all the icons are shown with the same background color (see example).

•Tap on a free icon (an unnamed one) or on the icon of an existing function. The new function is inserted at the tapped location. Icon colors are then restored.

If you tap on an existing function, this function and the next ones are shifted down by one location. Survey Pro will automatically create a new page of Home screen if the resulting number of functions on the screen is greater that what the screen can accommodate.

Removing a Function

On the Home screen, tap and hold the function you want to remove and select Remove Item. This instantly removes the function from the Home screen.

Moving a Function

•On the Home screen, tap and hold the function you want to move and select Move Item. Apart from the function you want to move, which keeps its original appearance, all other function items change color to blue.

•Tap on the location where you wish to move the function. This may be a free location, or the location of an existing function. If you tap on an existing function, the moved function will be inserted at the selected location and the function at that location and the ones that follow will be moved down.

Home Screen Pages

The default home screen consists of a single page. You may add up to three additional pages as part of the Home screen in order to make your many favorite functions accessible from this set of pages.

•Adding a page is done by tapping and holding any function on the Home screen and selecting Insert Page Before or Insert Page After.

•Switching from one page to the other is done by tapping on radio buttons at the top of the screen.

•Removing a page is done by tapping any location on that page and selecting Remove Page. This action requires user confirmation.

Screen Details The screen example below illustrates the different types of items you will usually encounter on the screen when using the different Survey Pro functions:

[5]

[6]

[2]

[7]

•Input Field [1]: An area where you can enter a specific value.

•Output Field: Only displays a value that cannot be changed.

•Simple Button [2]: Typically used to run the function described by its name. Just tap it to run the function. When the button name appears in red characters, you can alternately press the Enter key on the keypad to perform the same action.

•Power Button [3]: Typically used to provide context-sensitive functions to modify the corresponding field. Once you have tapped on it, a drop-down list will appear with several choices. Simply tap the desired choice from the drop-down list.

•Choose From Map Button [4]: Always associated with a field where an existing point is required. When the button is tapped, a map view is displayed. To select a point for the required field, just tap it from the map.

NOTE: If you tap a point from the map view that is located next to other points, another screen will open that displays all of the points in the area that was tapped. Tap the desired point from the list to select it.

•Scroll buttons [5]: When a button label is preceded with the > symbol, it indicates that the button label can be changed by tapping it, thus changing the type of value that would be entered in the associated field. As you continue tapping a scroll button, the label will cycle through all the available choices.

•Check boxes [6]: Tap on these boxes to successively check or clear the corresponding option.

•Tabs [7]: Many screens show tabs, which look like the tabs on index cards. Tapping on a tab displays a subset of information part of the selected screen.

The following buttons will appear in the area usually occupied by the command bar.

OK button. Accepts the changes made and closes the window.

Quick access to the Help system

Quick access to the Quick Pick list.

Map View The map view is a graphical representation of the objects in the current job. It will show basemaps in the background if you are using one (see screen example).

Basemap files may be either raster images (such as a georeferenced TIFF file, or a JPG image with an associated world file) or CAD drawings (DXF files). There are different map views depending on how the map view is accessed. Each can display slightly different information, such as a vertical profile. A bar is shown at the bottom of every map view that indicates the scale. The buttons along the left edge of the screen allow you to change what is displayed in the map view.

TIP: You can pan around your map by dragging your stylus across the screen.

The “main” map view is the one you get after tapping in the command bar (from the Home screen or Main Menu).

From all those screens including a button, you will also display a map view after tapping this button.

The “main” map view, as well as any map view accessible from a survey routine, will also function as an “active” map. That means you can perform several actions directly from the map. Tap and hold on the map to bring up a context menu of available actions. The actions available will depend on what you have selected at the tap-and-hold location.

The main map can also function as an interface to collect measurements. Tap and hold on the main map and choose Survey Mode to enable the Measurement

interface (see screen example for GNSS).

When in Survey Mode, you can collect data from the main map by tapping on one of the available buttons (see table below).

You can also press the Enter key to trigger an observation. By default, the Enter

key will trigger a “Topo” observation. You can change the Enter key to trigger a point observation by clearing the Survey Map Use Enter Button for Topo prompt on the Job > Settings > Surveying tab.

Shortcut buttons are available to optimize your work. These are defined below:

Survey Pro cannot start without a job being open. Upon launching Survey Pro, the Welcome to Survey Pro screen will guide you through the process of creating a new job

or opening an existing job.

NOTE: Upon launching the onboard version of Survey Pro, the initial screen allows you take measurements without having to open a job. Refer to 8. Survey Pro’s On-Board Version on page 58.

•Tap the New button. The New Job screen opens, which prompts you for a job name where the current date is the default name.

•Either type in a new job name or accept the default name.

•You can create the job in two different ways:

1.Tap the Create Job Now button. The new job will be created with the current default settings (as listed at the bottom of the screen) and will be stored in the default directory (\Survey Pro Jobs\).

2.Tap the Settings button to access the different job settings (see below). After you have gone through the different settings, tap the Finish button. This will create and store the new job.

NOTE: The job names listed in the upper portion of the screen are those of the most recent jobs

you opened in Survey Pro. This list does not necessarily reflect the list of jobs stored in your data collector. If you are looking for a job stored in your data collector, use the Browse button.

Job Settings The settings and values entered for a new job become the default values for any subsequent new jobs. A short description of the jobs settings is given below.

•Units [1]: When creating a new job, set all the desired units for the job. You can also enable the setting for Earth Curvature and Refraction correction for optical measurements.

•Control File [2]: Control points can optionally be imported from another existing job by checking the Use a Control File check box. After tapping Finish to create the job, a message will indicate the number of imported points. If you are using a control file, by default the coordinate system of this control file will be used for the new job. You can override this default setting on the coordinate system page. A control file can be imported from either a .Job or .Survey file.

•Select Coordinate System [3]: When you are using a control file, you can start the job with the control file’s coordinate system, or you can pick a different coordinate system from the database. If you don’t have a control file, you need to choose the coordinate system for the job. To select the coordinate system for the new job:

–Clear the check box when you are doing an optical survey with a ground scale factor of 1, or if you are doing a GNSS survey and there’s no known projection or datum for your local grid coordinates.

–Check this box when your local grid coordinates are defined by some known map projection and datum.

Understanding Scale Factor for your coordinate system:

–If your job has “no coordinate system”, Survey Pro automatically sets the scale factor for optical measurements to “1.0”. This means that the distance

measured on the ground will be 1:1 to the distance on the grid. If you start a GNSS survey, Survey Pro will use default Ground Calibration mode to calculate your grid coordinates from GNSS measurements.

–If your job is using a map projection and datum, Survey Pro will automatically calculate the correct scale factor for each station setup so the distance measured on the ground will properly be reduced to the coordinate grid. If you start a GNSS survey, Survey Pro will use the selected projection to calculate grid coordinates from GNSS measurements.

NOTE: You can modify the default optical scale factor settings in the Job > Settings > Scale

Factor tab.

•First Point [4]: A default point name and coordinates are prompted to become the first point in the job. You can freely change the name and coordinates of this point before creating it. You may also clear the box if you do not want to create a new point at this stage.

You may start your measurements now if you don’t need anything else in your job at this time. In that case, go directly to 4. Connecting Survey Pro to an Instrument on page 15.

If you need to add data (points, polylines, alignments, etc.) into your job before starting, the sections below will tell you how to import or create/edit data from within the open job. The last section lists the possible formats in which the data stored in the job can be exported.

Importing Data Use the File > Import function to add points to the open job. The points may be imported from different file formats:

•Survey Pro native formats (*.Survey, *.JOB, *.JXL, *.CR5). JXL is the extension for files in JobXML format, a Spectra Precision standard format for point, alignment, and measurement data.

•LandXML (*.XML), an industry standard format for point, alignment, and measurement data.

•Text format (*.TXT, *.CSV). An Import ASCII wizard will help you define the content of every TXT file you will import.

Survey Pro will parse and import all the known elements from the chosen file. These elements will be added to the current job as points, polylines and alignments. See the definition of these elements in Editing Points on page 13, Editing Polylines on page 14 and Editing Alignments on page 14.

The File > Import Control function is used to import points onto the control layer of your job. Points on the control layer are protected from being modified. Control files should be in *.Survey or *.JOB format.

Editing Points A point in Survey Pro has coordinates and properties. A point’s coordinates can be derived in one of two ways:

•Key-in point: The coordinates for this point were entered using the Job > Edit Points function (Insert button) or this point was created by importing data to the job.

•Observed point: The coordinates for this point are calculated from measurements in the current job.

NOTE: To see the current coordinates and properties of a point, you can tap the point on the map. This will open the Point Details screen showing the Origin of the point, which describes

how the point was created.

You can use the Edit button of the Edit Points function to modify the description, layer, picture and features of any single point. With a selection of multiple points, you can use the same button to modify the description and layer of the entire selection.

Selecting several points not in sequence is obtained by first activating the Control key and then tapping successively on the points to edit. The Control key is accessible from either the virtual keyboard (CTL key on Nomad, Recon or ProMark 200) or the real keyboard (CTRL key on Ranger). The Shift key can also be used to select several points in sequence.

You can use the Edit button of the Edit Points function to modify the coordinates of any key-in point in the job. The Location tab allows you to enter coordinates for the point. You can enter Grid, global geodetic (WGS84 LLH) or local geodetic (Local LLH)

coordinates.

•Grid: This point’s local grid coordinates are the Northing, Easting, Elevation values that were keyed in or imported. This point’s global geodetic coordinates will be calculated by transforming grid coordinates into latitude, longitude, height coordinates using the current projection.

•Global geodetic: This point’s WGS84 coordinates are the latitude, longitude and height values that were keyed in or imported. This point’s local grid coordinates will be calculated by transforming geodetic coordinates into Easting, Northing, Elevation coordinates using the current projection.

•Local geodetic: This point’s local geodetic coordinates are the latitude, longitude and height values that were keyed in or imported. This point’s grid and global geodetic coordinates will be calculated by transforming the local geodetic coordinates with the current projection.

Use the File > Export function to export data from the open job to one of the supported file formats. For most formats (Survey, JOB, TXT, CSV, XML, CR5 and DXF), you may select the portion of the current job you wish to export. For export to Survey Pro 4.x (Job/RAW) or JobXML format, the entire job database will always be exported.

Remote Control Screen

If you are using a robotic total station, use the Survey > Remote Control function to control the total station from the data collector running Survey Pro.

In addition to providing the same level of control as Survey Pro’s onboard version, the Remote Control screen constantly provides information about:

•The charge status of the battery used in the total station

•The operating status of the total station (IDLE/ MEASURING/Locked)

•The quality of the radio link between the robotic total station and the data collector.

The following buttons are also available from this screen to control the instrument:

•GeoLock button: Launches a GPS-assisted search for the prism

•Search button: Launches a search for the prism starting at the current instrument direction

•LockNGo button: Enables or disables the lock-and-go feature

•Stop button: Stops the current turn or search operation

•Turn To button: Opens up the “Turn To” screen where you can select a point or angles to turn the instrument to.

The following icons are made available next to the title bar:

Visible laser pointer off. Tapping on this icon will turn the laser pointer on.

Note: Standard safety precautions should be taken to ensure that persons do not look directly into the beam.

Visible laser pointer on. Shown to indicate the visible laser is currently active. In the command bar, the instrument icon will then look like this:
