Berlin FIS-Broker download scripts

Convert the ATOM FEED of the Berlin Geo-Data-Portal to GeoTIFF to create tile for Leaflet or openlayers.

More info in the README.md files of the directories.

Conversion

Conversion is done following http://blog.cleverelephant.ca/2015/02/geotiff-compression-for-dummies.html. In particular:

gdal_translate -co COMPRESS=JPEG -co PHOTOMETRIC=YCBCR -co TILED=YES -a_srs EPSG:25833 ECWFILE GTIFFFILE

and

gdaladdo --config COMPRESS_OVERVIEW JPEG --config PHOTOMETRIC_OVERVIEW YCBCR --config INTERLEAVE_OVERVIEW PIXEL -r average GTIFFFILE 2 4 8 16

rsync

To copy only the converted tif files and the vrt to a remote server use:

rsync --delete -av --include="*/" --include="tif/*.tif" --include="*.vrt" --exclude="*" ./ USER@SERVER:PATH/

ECW files

In order to process ecw files, gdal needs to be compiled agains the proprietary ERDAS library (see also: https://trac.osgeo.org/gdal/wiki/ECW).

1. Download the ERDAS installer from https://download.hexagongeospatial.com/downloads/ecw/erdas-ecw-jp2-sdk-v5-4-linux. Run the installer with bash to install into ~/hexagon. Move the directory afterwards to /opt/hexagon.

2. Then, obtain and build gdal-2.2.4 from https://trac.osgeo.org/gdal/wiki/DownloadSource.

3. Extract the gdal source, change to the directory, and:

   ./configure --with-ecw=/opt/hexagon/ERDAS-ECW_JPEG_2000_SDK-5.3.0/Desktop_Read-Only
   make -j 8
   make install
   

4. On Debian 9.0 an additional softlink needs to be created:

   ln -s /opt/hexagon/ERDAS-ECW_JPEG_2000_SDK-5.4.0/Desktop_Read-Only/lib/newabi/x64/release/libNCSEcw.so* /usr/local/lib/
   ldconfig
