DESCRIPTION:As transmission operator (Austrian Power Grid) we need up to da
 te information on parcels and land use during building projects. The Austr
 ian data provider in this field (Federal Office of Metrology and Surveying
  - kataster.bev.gv.at) provides an open data vector tile cache with this i
 nformation on a daily basis. The vector tile format is good for visualisat
 ion\, but for the export of distinct multiple parcel-geometries\, there is
  no out-of-box solution in QGIS so far. \n\nWe present a methodology of do
 wnloading data from vector tiles based on a defined spatial selection with
  PyQGIS. Based on a geometry (e.g.\, a power line) we are able to select t
 he parcels of interest. One challenge is the fragmented provision of data 
 by vector tiles. Using GeoPandas we combine the tiles into distinct geomet
 ries which can be postprocessed. \n\nThe result are precise parcels includ
 ing attribute data and metadata. The challenge is to reduce the amount of 
 data in the spatial selection process to find the parcels of interest.
