Vowa Baselayers – Implementation and Maintenance

Implementation 
 The QGIS plugin is implemented as standard QGIS plugin with Python. It uses tables in the schema qgis_tools in the DPSpatial database for storing the information on the layers to be loaded into QGIS. The documentation on the tables of this schema is  on this page . The QGIS plugin repository can be found  on the Vogelwarte GitLab . 
 Purpose, installation, and usage of the plugin are documented on this page . 
 
 Layer Types 
 The following layer types can be provided through the QGIS plugin: 
 
 WMS 
 WMTS 
 QGIS Layer File 
 Shapefile 
 GeoPackage 
 GeoTIFF 
 PostGIS Vector Layer 
 
 Each layer type requires a set of parameters so that it is loaded properly in QGIS. You find the specification on this page . 
 
 Test Layers 
 In order to add layers in the table vowabaselayers that are only visible for development and test users you have to do the following: 
 
 Create the environment variable "VOWA_BASELAYERS_DEV=true" on your computer. 
 Add the layers and give them IDs greater than 1000. 
 
 
 &-Character in Tab Titles 
 The QGIS plugin replaces '&' characters in tab titles by default with '_'. If you want to use the '&' character in tab titles type it twice. For instance, the tab title "Lakes && Rivers" will be shown as "Lakes & Rivers" in the QGIS plugin.
