Austrian Address Data (BEV)

Austrian Bundesamt für Eich- und Vermessungswesen (BEV) has made the Austrian Address Register freely available:

• Data: http://www.bev.gv.at/portal/page?_pageid=713,1604469&_dad=portal&_schema=PORTAL
• TOS: http://www.bev.gv.at/portal/page?_pageid=713,2573888&_dad=portal&_schema=PORTAL

However, the main file (ADRESSE.csv) contains three coordinate systems (EPSG:31254 (Austria GK West), EPSG:31255 (Austria GK Central), EPSG:31256 (Austria GK East)) and is too big to be converted to a shapefile directly.

This tool (Windows only) strips all attributes and creates a CSV with EPSG:31287 (MGI / Austria Lambert) coordinates.

Known Issues

If there's an error message like

could not initialize EPSG:31287
No such file or directory

set the environment variable PROJ_LIB before calling convert-bev-address-data.exe to the full directory path where the file espg is located:

SET PROJ_LIB=C:\FULL\PATH\TO\EPSG\FILE\DIRECTORY

Usage

      convert-bev-address-data -i <PATH-TO-BEV-DATA-DIRECTORY> [-o] [-e] [-d]

options:
  -i, --input=VALUE          diretory containing extracted CSVs
  -o, --output=VALUE         output file, optional (default: out.csv)
  -e, --epsg=VALUE           target epsg code, optional (default: 31287)
  -d, --decimals=VALUE       decimal places, optional (default: 6)
                               depending on the chosen output crs it makes
                               sense to limit the number of decimal places.
                               e.g. 6 decimal places don't make sense for crs
                               with [m] units.
                               But it makes sense to have 6 decimal places with
                               EPSG:4326.
  -u, --usage                show this message and exit
