- Layer Name – an alias for the Data Layer e.g. Graffiti.
- Layer Type – the type of geographical data e.g. Spatial or DataPoint.
- Node SQL – the SQL to use in order to select/filer the data e.g. select * from Incidents (Table) where Type (Field) = ‘Graffiti’.
- Unique Field - the Id or sequential number field for that table.
- Database – the name of the database that contains your spatial data e.g. ReportIt.
- Geographical Tablename – database table that contains the incidents e.g. incidents.
- Geometry Column – the field in the source data that contains the spatial geometry.
