Getting Started with Data Acquisition – Data Acquisition Settings part 1

Following are some notes which highlight important Data Acquisition settings.

For the sake of convenience I'm abbreviating the term Data Acquisition as 'DA'.

DA reads and uses the settings of the DGN. Most settings in your existing seed files should be fine.

But there are some DA specific settings which you must check.

To check and modify settings, go to the CAD menu > Settings > Design File...

You might want to check the Angle Readout and the Working Units.

The following screenshots show Dutch settings:
  

 

The DA specific settings are only available when DA is started. So if you select the Data Acquisition category, and don't get any settings, then you probably haven't started DA yet. In that case you must close the settings dialog, start DA and re-enter the settings dialog.

 

The first thing you want to enter is the Style File Name which shall be used in DA.

Click in the right column of the Style File Name property. A browse button will appear. Click on the browse button and use the File Open Dialog to select a GEOPAK SMD (XML), InRoads XIN or MXROAD PSS file.

Note for GEOPAK Users:
You must first convert your SMD file into a XML file.

Make sure you use the correct file filter in the file selection dialog.

 

When your survey data only contains coordinates, ie. no observations, then you will probably set the property Import Coordinates As Control Points to Never.

 

Often the survey code doesn't match the feature code of your style file (SMD, XIN or PSS). In that case you can use Substitute Strings to map the survey code to your feature code:

In the following example points with the survey code '100' become features starting with 'PDU', points with the survey code '101' become 'PBO' features, points with the survey code '102' become 'SR' features, etc...

You can paste entire tables from excel or text editors using the 'Paste Special' function. That way you can easily transfer existing survey libraries to DA.

Click on 'Accept' to use the settings.

 

Data Import Items lets you specify file filters which you see in the various file open and file save dialogs. DA is easier to operate if you enable here only those filters which you commonly use. Also, survey files of one data format sometimes use different file extensions. For example SDR33 files are sometimes called *.sdr, and sometimes *.dat. You can specify here the file extension of each data type. This makes file selection easier, and it's even required to get the drag and drop functionality working properly.

If you only use a few data formats, you can do the following:

Click into the grid, press 'Control+A' and then click the 'Exclude' icon in the toolbar. This will exclude all items.

Then select only those items you want to use:

For example for MX, select 'MX Surface (*.fil)', 'MX Styles (*.pss)' and the data formats you want to be able to import, say SDR33. Click 'Use' when you've selected these items:

Click on 'Accept' to use the settings.
