Geodata layer

A Geodata layer is a representation of one or many geospatial datasets within a GIS System. It can contain additional representation information such as visualisation, labelling of the dataset, visibility under certain conditions based on scale, SQL query, etc.

Geoprocessing workflows

Geoprocessing workflows are usually defined as a set of Geoprocessing tasks organized into a process. Geoprocessing tasks are functions of a GIS system used to manipulate, transform or manage geospatial datasets, maps and tables.

Geospatial dataset

Geospatial datasets are sets of records defining a type of object in space. For example a vector dataset of roads will contain graphical representations of roads and a respective table containing attributes describing each object within the data model of the dataset.
