Data source - ObjectVision/GeoDMS GitHub Wiki

A typical workflow for a GeoDMS project is to

• read data from a (set of) data source(s) (files/databases). Look here for more information on how to configure this
• calculate results in memory, using arrays
• view results and or write data to files/databases. Look here for more information on how to configure this.

So-called StorageManagers are used to read data from and write data to files/databases.

We advise configuring source data items in a source data container; these data items can be referred to from any other location in the configuration.

Data can also be explicitly exported with the GeoDMS GUI with the File > Export Primary Data menu options.

To learn how to configure this, look here

vector, grid and nonspatial data

For spatial data, a distinction is made in:

• [Vector data]]: [[point]], [[arc]] or [[polygon]] geometry data for [one-dimensional domains
• [Grid data]]: [attributes for two-dimensional domains

In GDAL this same distinction is used, gdal.vect or gdalwrite.vect is used for vector data, gdal.grid or gdalwrite.grid for grid data.

Non-spatial data can also partly be read from or written to with gdal.vect or gdalwrite.vect, but also by some other StorageManagers.
