Custom scripts for OpenStreetmap

Here is an overview of the custom shell / Perl / Python scripts I have used to do my own processing of OpenStreetmap data. While they are usable for their purpose, to get the most out of them, you should view them as examples to understand and modify.

Downloading OpenStreetmap data

• get-shapefiles.sh A shell script downloading continent outlines and national borders. Mirrored here, originally from a map style source repository.

Rendering

The following rendering scripts require a live PostgreSQL / PostGIS database with OpenStreetmap data.

Rendering standard OpenStreetmap tiles

These also require renderd from the mod_tile package to be running.

• render_list-rect.pl calls render_list repeatedly to render tiles at multiple zoom levels but restricted to a rectangular region.
• The small C program missing_tiles.c lists which tiles at a zoom level an in a region have not yet been rendered. It is a hack based on render_list.c (the render_list main program). To build it, copy it to the src subdirectory of the mod_tile sources, build render_list and then run this script.

Dealing with metatiles

(These don't need the PostgreSQL / PostGIS database but process rendered metatiles.)

• osmmetatileinfo.pl prints the zoom level and coordinate index range of metatile files.
• unpackmetatile.pl extracts the tiles from a metatile file. More info...
• osmgettile.pl extracts a tile from a tile cache directory. More info...

Rendering larger map regions

• renderosm.cpp renders a rectangular map region. More info...
• renderosm.py is its less capable predecessor in Python

GPS surveying

• wintec2000-extract.pl converts binary data from the Wintec 2000 GPS logger into a white space separated ASCII table.
• smoothtrack.pl smooths a track represented as ASCII data.
• txt2osm.pl converts ASCII table data into OpenStreetmap XML for import into JOSM.
• txt2kml.pl converts ASCII table data into KML.
