shell_scripts

bash shell scripts for batch geoprocessing spatial data using OGR2OGR

Requirements

Install FWTools (I used the Linux 64-bit version which is here.

Make sure ogr2ogr is working in command line with basic command: ogr2ogr

I suppose you could just add the shell_scripts directory to your PATH, but I just run the commands with the full file path.

Reference Material

These resources have helped me a lot in building the ogr2ogr batch commands:

• Directory of Spatial Reference Systems (SRS)
  • FYI, GitHub currently likes (i.e., requires) urn:ogc:def:crs:OGC:1.3:CRS84 for displaying geoJSON.
• List of OGR-supported Vector Formats...so many options!

sshp-to-geojson.sh

Description

This converts all shapefiles in a directory $DIR1 into geoJSON files in $DIR2. If $DIR1 is not specified, the script looks in the present working directory. If $DIR2 is not specificied, the script will place the new geoJSON files in a new subdirectory called geojson.
