Attention! Please note that when entering elements in the software with known coordinates, these must be expressed in plane coordinates, i.e. expressed in plane units of measurement (cm, m, km, etc.). The plane reference systems (plane map projections) available in cartography are expressed in m (example: UTM-WGS84 33N spindle with EPSG code: 32633, UTM-WGS84 32N spindle with EPSG code: 32632, UTM-ED50 33N spindle with EPSG code: 23033 etc.). Use coordinates with the same reference system (DATUM) for both the topographic surface and the surveys or other element to be inserted. Do not use geographical coordinates expressed in angles (latitude and longitude)
Before inserting the probing, the topographic surface must be created. From ‘Topographic surface and stratum’ in Workspace, right-click and then click ‘Import topographic surface’:
Then load the text file containing the coordinates of the topographic surface. In this case we are dealing with UTM plane coordinates formatted in Coord. North, East, Z. In the import window, the ‘Axis translation’ option brings the imported surface closer to the local origin of the reference system to improve calculation fluidity. In our case, you want to keep the original coordinates, so uncheck this option and press ‘Continue’:
Once the topography has been imported, click on ‘Topography’ in the Workspace and the imported surface will be shown, with the coordinates at the bottom left:
The next step is to add the test manually by right-clicking on ‘’Test Surveys‘’ and then ‘’Add Test‘’:
A window appears at the bottom left with the data to be entered for the Test:
Under ‘Test Code’ and ‘Test Description’ you can enter a test identification code and a test description respectively. Under ‘Test Positioning’, information on the position of the test is entered. In particular, if the ‘Shift Axis’ option is not activated, the original survey coordinates are maintained in xs, ys and zs by entering the East co-ordinate in xs, the North co-ordinate in ys and the elevation in zs respectively:
The Test will appear on the surface:
If the ‘Axis Translation’ option is enabled, entering the original coordinates on the right-hand side, i.e. North, East and Altitude, the programme will generate the translated coordinates so that they are close to the local origin:
The probe point will be inserted together with the topography points:
