In dpPower, you can import and use geographical survey data gathered in the field using various survey systems, such as total stations (TPS) or hand-held computers with GPS pods. Surveyed geo objects are defined by their coordinate values (X, Y, Z), stored in a text file format (ASCII or ANSI), and ready to use in external systems. Such measurement data files containing sets of surveyed coordinates (sometimes known as geo data, geographic data or field data files) come in different formats and specifications. dpPower supports a variety of system formats, including Marit and Geodos.

Imported objects are not topologically linked to each other. Therefore, be sure to link all objects before posting the changeset. |
Mapping measured objects
When a measurement file is imported, measurement objects can be translated into appropriate objects in <% PRODUCT%> via a mapping. The mapping of objects is controlled in a database table. Users with administration rights in the system may use the Table manager in the Administration menu to create and edit object mappings in the relevant database table.
It is possible to set that field objects without mapping are imported as free graphics. This type of graphics can not be posted, but it can be used as a reference when placing or editing objects in the map.

Import measurement data
1.Select File > Import > [desired measurement file format]. A dialog opens.
2.Select the desired options in the dialog box.
3.Press Import file. When the import is complete, the application automatically zooms to the area of the imported measurement file.
Options in the dialog box
The Import tab:
•Import uncoded objects as Free unpostable graphics - Mark this check box to import unmapped data as Field data objects. If the checkbox is not marked unmapped objects will not be imported.
•Browse - Open the file catalog and select a coordinate file to import. You can import several files at once.
•Field separator (For Geo data) - Select semicolons or comma as field delimiters.
•From - Select the coordinate system used in coordinate data file.
•State (For Geodos and Trimble) - Select the state for the imported objects.
•Select character set - Select the correct character set to ensure that text and special characters in the measurement file are displayed correctly after import.
•Accuracy - Select the accuracy of the measurement.
•Origin - Select the origin of the measurement.
