The use of geodata in the GDI-BE is based on the provision of vector data.

Raster data are only used if no vectorization is possible.

PDF maps are not machine-readable geodata and are not used in the GDI-BE.

GeoTIFF/ TFW

Vector data

Keywords are used for the presentation and the research of the data.

They are essential to gain information about the data and services.

Services (WMS, WFS, Atom) are tools which are related by metadata.

The data delivery (metadata / geodata) must take place at least 4 weeks prior to the desired activation on the Internet. A cycle of updates is to be defined.

Data is to be provided in the coordinatsystem ETRS89 / UTM Zone 33N (EPSG:25833). Refer to Amtsblatt für Berlin, Heft 1/14 vom 03.01.2014.

Point of contact

A contact person must be designated by the data-holding body.

A permanent backup is to be ensured by the data providing department.

The storage of geodata on the geodata server (K-drive) or on the ArcGIS server represents a secondary dataset, which is used for publication in the Geoportal.

Quality assurance

Data backup

The Unit III D does not assume any quality and quality assurance of the data.

The geodata services can be found through catalog services and in the geoportal.

Data provision - Download

Search, find, view

Geodata is provided via geospatial services as a WebFeatureService or ATOM feeds. Each geospatial dataset, which is offered for download via ATOM feed, is provided in a data format. Compressed raster data is provided.
