Misc_GIS_scripts

A place to store my scripts involving GIS data.

layer_data_extractor.py

Script to extract the values of a rasterfile in a list of provided coordinates. Requires a shapefile and rasterfiles.

Usage:

python layer_data_extractor.py shapefile.csv rasterfile(s)

The "shapefile.csv" should have a header and the following data: LABEL LAT LON. The separator can be any number of spaces and/or tabs. Eg:

LABEL   LAT LON
Ind.1   41.6611 -7.8747
Ind.2   43.4997 -8.3164
Ind.3   39.5677 -6.6573

The rasterfile(s) can be globed in the shell or provided one by one. The output is sent to STDOUT.

Example usages:

python layer_data_extractor.py ~/shapefile.csv ~/GIS_data/BioClim1.bil ~/GIS_data/BioClim2.bil

python layer_data_extractor.py ~/shapefile.csv ~/GIS_data/BioClim3.bil > Extracted_data.csv  # To export to a file

Note: In order to use .bil file, the respective .hdr files must be placed in the same directory.

Requirements:

This script requires the package python-gdal to work.

Coords_to_Google_Earth.py

This is a very dirty hackish script to get a coordinate file and produce a Google Earth input file with place-marks.

Usage:

Format a csv with coordinates:

Sample name, Longitude, Latitude, Altitude

Just use the program like so:

python3 Coords_to_Google_Earth.py coords.csv new_file.kml

And you are good to go.

simple_coordinate_converter.py

This script will convert a csv file wing tabs as separators with DMS coordinates into decimal coordinates. It outputs to STDOUT.

Usage:

Format a csv with DMS coordinates:

Sample name, Latitude, Longitude

python3 simpe_coordinate_converter.py coords.csv > output_file.csv

That's really all there is to it...
