Different data types

In GeoDMS you can read many different data types:

  • Tables: .csv, .asc, .dbf, .xml, .xdb, .txt
  • Grid raster: .tif, .asc
  • Vector: .shp
  • GeoDMS' own data storage file: .fss
  • Databases: MsAccess, MsExcel, PostgreSQL, PostGIS, FileGeoDatabase

In the following configuration file you'll see example of how you can configure several common data types: download configuration. How to set up this configuration see Template:Module 0: Install GeoDMS GUI and setup a configuration

GeoDMS cannot check whether certain data types have been changed between sessions, i.e. shapefiles. Therefore, it recalculates everything that uses such data types. A way to circumvent this and thefefore speed up repeated calculation is to save such data type to GeoDMS' own data storage file (fss). You have to do that once and then direct expressions towards that disconnected data attribute.
