E-government interface analysis interface

The e-government interface analysis interface is a web service provided via the e-government basic component Geodata (GeoBAK). The analysis interface returns property data for one or more graphic objects (point, line, polygon, circle as polygon) after a selectable spatial assignment to various, mainly area-based object types (e.g. districts/circle-free cities, parcels). The web service is optimised in terms of performance and therefore transfers no geometry in contrast to a WFS. The document “GeoBAK Analysis Interface — Overview Geodata Topics” provides an overview of the object types that can be retrieved from the analysis interface and their attribute structure. The focus is on INSPIRE topics. Previously, intersect, within, nearestneighbour and valuesatpoint have been set up as spatial assignments (operators). The operations intersect and within are defined in such a way that both are excluded. Intersect (default value): Returns all features that are touched by the passed geometries. Within: Returns all features in which the passed geometries are fully included. Nearestneighbour: Return features with the shortest possible distance. Use for determining the nearest address (reverse geocoding). Valuesatpoint: The values are returned at the given point. There is a overlap with raster data. In response, the analysis interface provides a JSON array with several objects combined for the different object types. A numbering of the objects (objectNo) is done in an analog way as the objects have been passed over. This allows applications and electronic technical procedures to transfer coordinates and geo-objects and retrieve numerous information from an object.
