How it works
This software reads an OpenStreetMap planet dump (or one of its smaller extracts) and produces an Spatialite database which contains all errorenous objects which were found in the OpenStreetMap data. Other output formats than Spatialite are possible but not as well tested. You can open the output files using QGIS.
The Spatialite database is used as the data source of the WMS service by the OSMI backend. This service provides the map and an GetFeatureInfo API call used by the frontend.
- C++11 compiler
- libosmium (
libosmium-dev) and all its [important
- GDAL library (
- proj.4 (
- CMake (
You can install libosmium either using your package manager or just cloned from
its Github repository to any location on your disk. Add a symlink libosmium in
the top level directory of this repository to the location of
libosmium/include if you use the latter variant. Take care to use libosmium
v2.x not the old Osmium v1.x!
mkdir build cd build cmake .. make
./osmi_simple_views -h to see the available options.
There are two binaries.
osmi_simple_views_merc can only produce output files
in Web Mercator projection (EPSG:3857) but is faster than
because it uses a faster coordinate transformation engine provided by libosmium
osmi_simple_views calls Proj4.
