Important Notes About This Tutorial:

• This tutorial will walk through the functionality of the tap-map in SmartWorx Viva. Although the tutorial is based around a DXF file, you do not need a DXF to use the tap map; all of the functionality discussed below can be accessed in any survey job with measured points & lines.
• This tutorial can be completed on a CS10/15, TS15 or PC simulator, no instrument connection is required.
• There are two different methods of using DXF data into your survey job:
  1. Importing all points and lines onto the survey database at once, through ‘Jobs & Data’ -> ‘Import Data’ -> ‘Import DXF data’. Using this method will convert the dxf points & lines into the Leica job database. If the DXF file is quite large, this method can make the controller run slower than usual.
  2. Attaching the DXF as background layer(s) and then importing points & lines to the survey database as required. This is preferable in most cases as it allows CAD layer control, reduces the load on the memory, and leads to less ‘clutter’ in the survey database. This method is covered in this tutorial.

Using Tap-Map & DXF Files Tutorial

Set up Job and Attach DXF

1. Download the dxf from the following link Dropbox link: https://www.dropbox.com/s/dgugel0gwtqc9po/dxf%20tutorial.dxf. As with any non-Leica data file, this needs to be placed within the DATA directory on the USB stick or SD card.
2. Create a new job within SmartWorx Viva. To do this go to ‘Jobs & Data’ -> ‘New Job’, enter the job name, then select the tab ‘CAD files’.
   
   
3. Select the applicable dxf (‘dxf tutorial’ in this example), press ‘F4.Attach’, and then ‘F1.Store’ to attach the file to the current job.  (This will create a Leica version of the dxf which is accessible in SmartWorx).
4. When back in the main menu, press ‘F6.Map’, and then zoom to fit  . You should now see the attached DXF in the background of the job. This DXF will now appear in the map screen of any SmartWorx application.

Tap-Map Navigation & Display Options

1. You’ll notice that there is some information on the screen (in this case, some text layers containing identifiers and elevations) which are not relevant at the moment. In order to reduce clutter, we can turn different CAD layers off. To access layer control, press FN, then F4.’Layrs’. Using the F5.’State’ key, you can toggle the layers to be visible, hidden or selectable. ‘Visible’ is useful for showing information to help the surveyor establish where they are within the job, without accidentally selecting features from that layer. In this example, we will hide DEFAULT, ELEVATION, IDENTIFIER and SYMBOL, as these were created as text layers when the drawing was created. Select ‘Store’ to confirm the layer selection. 
2. There are two ways to navigate within the tap-map, using the keyboard and using the screen commands. On the right hand side of the screen, select the  ‘zoom to fit’,  ‘zoom in’,  ‘zoom out’,  ‘window zoom’ &   to centre to a selected point or current position. These view functions also can be triggered on the keyboard using the 1, 2, 3 or 5 keys. To pan the view, press the stylus on the screen and drag across.
3. You can also customize the map to display point IDs, elevations and other information. Press FN, then F2.’Config’ to look through the settings in the ‘General’, ‘Points’, ‘Lines & Areas’ tabs to see what can be displayed. Keep in mind that points need to be imported (this is covered in the next section) for most of this information to be displayed.

Importing & Using Points and Lines from the DXF

1. Since the DXF has been attached to an empty job, you’ll notice that there are no points, lines, or areas in the data screen to use with the SmartWorx applications. You can press  in the upper part of the screen to access the point database at anytime.
2. Firstly, configure the tap map import settings to your specifications. Press FN then F2.’Config’, and then select the ‘CAD import’ tab. The prefixes can be adjusted to suit the numbering requirements of the job. The other important setting is the ‘create points at vertices of lines’ – This will, on import of any line, create points at the vertices, which make it very convenient to stake the start of, the end of lines, and vertices in polylines.
3. There are two ways of importing points using the tap-map:

1. Press down the stylus on the feature for one second to bring up the action box, and then select ‘Import’.
2. Tap several features on the map, and then hold down the stylus anywhere on the screen to bring up the action box, and then select ‘Import’. You can also use the ‘box select function’ which is in the second level of the ‘view’ toolbar, accessible through the  button.
   

   Single Point Import

   

   Multiple Point and Line Import

A feature highlighted in red means that it is currently selected. To deselect features, just tap the feature again. To unselect all features, hold down the stylus on the screen, and then select ‘clear selected objects’.

If you select a region of the screen where there are multiple features (for example the electrical service in the corner of the lot), a dialog box will appear.

This shows all features within the proximity of the selection. You can toggle the selection on/off for each feature by pressing F6.’Select’ then F4.’OK’ to confirm.

1. Navigate to the upper left side of the subdivision, and import the green survey control point      . Notice that after the point is imported it becomes a standard Leica control point      and a point ID appears. This means that the point is now in the SmartWorx point database and can be used in any application.
2. Repeat the process, but this time select multiple points and lines & import them into the survey database.
3. The process of importing points and lines can be completed automatically if the feature is to be used in a SmartWorx application, for example ‘reference line’ or ‘point stakeout’.
4. Navigate to the upper right side of the subdivision, and then hold down the stylus on the control point until the action box appears. Select from the following options on the point:
   • Turn to point (TPS only) – will turn the Total station to the point
   • Check point (TPS only) – will import the point automatically, then turn the instrument to take a check shot on that point to check residuals
   • Stake point (TPS and GPS) – will import the point automatically, and then enter the stakeout application to stake out the point.
5. Hold the stylus down on a property line near the survey mark. The following action box will appear.

(Use in Reference line actions)

(Use in Roads actions)

You can import this line directly into the ‘reference line’ or ‘roads’ applications, ready for measuring, staking or slope staking. For example, select ‘Stake line’, enter the distance and offset along the line you need to stake, and then press OK to enter the familiar line stakeout screen.

To return to the tap-map at anytime, press FN then F6.’Quit’.

COGO within the Tap-Map

The tap-map allows for the following COGO functions to be executed on points using the map screen. Work through the following examples:

If there are no values displayed, you’ll need to make sure COGO is configured to show ‘grid’ distances. This can be configured using the FN F2.’Config’ button.

• Traverse – Select one of the control points at the bottom of the job, then hold down the stylus on the screen and select ‘Bearing & dist from pt’. This will take you to the ‘traverse input’ screen, where you can specify the direction, distance and offset of the new point. Enter in the values from the screenshot below, then press F1.‘Calc’ to calculate the coordinates of the new point, and then F1.‘Store’ to create the new point in the map.

• Segment line – This function will create a number of points on-line between two existing points. Select the same two control points then hold down the stylus on the map, and then select ‘segment line’. Press ok to confirm the two selected points, and then in the following screen select the method for creating the points. ‘No. of segments’ will divide the line into points at an equal distance apart based on the number of segments. ‘Segment length’ will create points along the line at a defined interval distance. Set the segment length to 5m and set the starting point ID to 1000 (this will begin incrementing the new point numbers from 1000). Tap ‘Calc’ then OK to create the new points.

Creating, Editing, Coding & Deleting objects

1. Press and hold the stylus in an empty region of the screen, then select ‘create point here’ from the action box, then press OK to store. This will create a new point in the space on the map.
2. Select the point, then select ‘edit point’ from the action box, you can change the coordinates of the point, add or edit a code & attributes and also add an image to the point with the CS internal camera. Tap ‘store’ to save the edits.
3. Follow the same process with a line or arc; select two or more points, hold down the stylus then select ‘create line’, ‘create arc’ (when three points are selected), or ‘create area’.
4. Select the created feature, then hold down the stylus, and then select ‘edit’ from the action box to view the properties of the feature or change the coding & display of the feature. This is also a handy way to view areas of polygons and lengths of lines on the fly.
5. Select some points and lines, then hold down on the stylus to bring up the action box, and then select ‘delete’. This will not only delete the selected features from the map, but also the survey database… so use with caution.

That’s the end of the tutorial. Try using the tap-map and its features in your next survey job to see how efficient and easy it is to survey with Leica SmartWorx Viva.

The post Tutorial: Using the Tap-Map & DXF files in SmartWorx Viva v4.60 appeared first on Spatial Technologies.

Before you begin:

The accuracy of PPP is directly related to the occupation period of the GNSS sensor over the base point. The following link provides detailed information regarding expected accuracies when using the service. http://www.geod.nrcan.gc.ca/products-produits/ppp_acc_e.php

As a general rule of thumb, 40mm 3D accuracy can be achieved after 2 hours of constant occupation over a single point, and the maximum accuracy of around 10mm can be achieved after 12 hours.

PPP will process both GPS and GLONASS data, though it seems that there is a delay of around 24 hours after the survey until GLONASS data can be used in the correction.

Further reading on PPP can be found in the user guide at: http://www.geod.nrcan.gc.ca/userguide/index_e.php

Beginning the survey:

The process for survey is very similar in all Leica instruments capable of logging raw GPS data. If a license for on-board RINEX logging has been purchased, we’d recommend using that functionality as the RINEX file can then be uploaded onto PPP directly from the instrument. If the option has not been purchased, the data needs to first be converted using LGO (this will be covered later in the tutorial).

For this tutorial, I’ve used two Leica GS15 GNSS sensors, and a CS15 controller to communicate with each sensor. First, I’ve enabled data logging on the base sensor by going to ‘Instrument’ > ‘Base Settings’ > ‘Raw Data Settings’

N.B. A 15 second logging rate should be sufficient for PPP.

Start the base using a ‘Here’ (on System 1200, GS09) or ‘Over any point’ (Viva). It’s usually a good idea to check the data logging status on the instrument to ensure that logging has initiated and there is sufficient space on the storage device for data.

You are now able to connect to the Rover and complete the survey as per usual. When the survey is completed, power down the base sensor using the power button.

Uploading the raw data to PPP

On the SD card from the Base Sensor, locate the Rinex (.12o extension found in ‘Data’ > ‘GPS’ > ‘Rinex’) or the Leica raw files (MDB) which are contained in the DBX folder under the job name.

If using RINEX, the files can be uploaded directly onto PPP @ http://www.geod.nrcan.gc.ca/online_data_e.php

If using Leica MDB, the files first need to be converted to RINEX before upload. This can be done in LGO using the following method; Open a new project, then go to ‘Import’ > ‘Raw Data’ select the file type as SmartWorx raw data and select the MDB directory in the window. In the ‘assign’ window, remove any erroneous data and then assign the data to your new project. Rinex can then be exported by using ‘Export’ > ‘RINEX data’, or by a right-click > ‘Export to RINEX’ on any GPS track through the ‘GPS-Proc’ tab.The settings in this screen don’t matter too much, just make sure there is a separate file for each GPS track. This exported data can then be uploaded to PPP.

On the PPP website (sample above) you are able to select the coordinate system and epoch to apply to the output, as well as the email address to receive the results.

Shortly after submitting the files, you will receive an email from NR Can with the processing results. The corrected coordinates and estimated accuracies are contained within the email body, but it’s worthwhile downloading the report link for background and quality assurance. The results from my survey are shown below

Updating the RTK Survey in LGO

Transfer the raw RTK data from the survey controller to the computer using a portable storage device or ActiveSync, then import this data into a new LGO project using the ‘import raw data’ function in the toolbar. Assign the data to the new project, then select the view/edit tab to view the GPS data.

Because all RTK points are referenced to the base point(s), all that needs to updated is the coordinates of the base point, the rover points will then be automatically updated to the corrected coordinates.To do this, right click on the base point (in my example I’ve named it BASE). In the ‘coordinate type’ and ‘coordinate format’ fields, select geodetic and lat/long/height. Enter the lat/long/height from the PPP results, then press OK to update the coordinates.

I’ll now attach a UTM coordinate system and Geoid to the survey by selecting ‘File’ > ‘Project properties’ > ‘Coordinates’ tab, then selecting the coordinate system with geoid attached. In this example I’ve used a UTM10 north with a HT2 geoid. Press OK to confirm.

Finally, I’ve cross referenced the UTM coordinates and orthometric height with those provided on the PPP email in order to check that I hadn’t made a typo in my updated coordinate entry.

The LGO job can now be combined with more TPS/GPS data or exported for use in CAD.
