Geospatial Data

Geospatial data object containing a spatial reference in the form of coordinates. Often these are geocoordinate with the coordinate reference system srid:EPSG:4326.

Obtaining useful Data

A useful resource for geospatial data about Hamburg is GeoPortal. (Other cities/countries have their own agencies, such as the Federal Office of Statistics, that provide local, geospatial data). Follow these steps to obtain raster- and vector-layer data at Geoportal Hamburg:

  1. Click on Themen → Fachdaten
  2. From the list, choose the type of information you wish to obtain raster- or vector-data on and click the information icon next to it.
  3. In the info card that pops up click on WMS address if available.
  4. If not available, then click on Weitere Metadaten. This will forward you to metaver.de (MetadatenVerbund).
    1. On Metaver, click on one of the links under Verweise or Weitere Verweise.
  5. You will be directed to a site that contains an XML document. Copy the site's URL and paste it into QGIS to display the geodata.

Prepare Data

LIFE can consume multiple geospatial data format such as GeoJSON (*.geojson), GeoPackage (*.gpgk), GraphML (*.graphml) or ESRI Shapefile (*.shp) as for vector layers, or Raster CSV (*.csv), ASCII Grid (*.asc) for raster-layer.

To prepare non-conforming geospatial data for your model, you can convert it with QGIS as a useful public GIS processing tool.

  1. Download and install QGIS.
  2. Load your geospatial data into the QGIS application. This will produce one or more layer(s) in the Layer window (bottom left).
  3. Export the layer by opening the context-entries and selecting Export.
  4. Select an appropriate format, mentioned above or described here.
