Python wrapper for Gdal/OGR command line tools
Project description
Python library providing wrappers for the most common Gdal/OGR command line tools. Currently, only ogr2ogr and gdalinfo are supported. Note that this library requires GDAL/OGR tools to be installed in the system.
Installation
pip install pygdaltools
Usage
Gdalinfo:
import gdaltools info = gdaltools.gdalinfo("/mypath/myraster.tif") print info # output is the same generated by the gdalinfo command
Raster stats:
stats = gdaltools.get_raster_stats("/mypath/myraster.tif") print stats[0] # outputs a tuple: (band0_min, band0_max, band0_mean, band0_stdev) print stats[1] # outputs a tuple: (band1_min, band1_max, band1_mean, band1_stdev)
Ogr2ogr. From shp to geojson:
ogr = gdaltools.ogr2ogr() ogr.set_encoding("UTF-8") ogr.set_input("mylayer.shp", srs="EPSG:4326") ogr.set_output("mylayer.geojson") ogr.execute()
It can also be chained in a single line:
gdaltools.ogr2ogr()\ .set_encoding("UTF-8")\ .set_input("mylayer.shp", srs="EPSG:4326")\ .set_output("mylayer.geojson").execute()
Ogr2ogr. From postgis to shp:
ogr = gdaltools.ogr2ogr() conn = gdaltools.PgConnectionString(host="localhost", port=5432, dbname="scolab", schema="data", user="myuser", password="mypass") ogr.set_input(conn, table_name="roads", srs="EPSG:4326") ogr.set_output("mylayer.shp") ogr.execute()
Ogr2ogr. From postgis to spatialite, specifying a different output table name:
ogr = gdaltools.ogr2ogr() conn = gdaltools.PgConnectionString(host="localhost", port=5432, dbname="scolab", schema="data", user="myuser", password="mypass") ogr.set_input(conn, table_name="roads", srs="EPSG:4326") ogr.set_output("mydb.sqlite", table_name="roads2010") ogr.set_output_mode(data_source_mode=ogr.MODE_DS_CREATE_OR_UPDATE) # required to add the layer to an existing DB ogr.execute()
Ogr2ogr. From postgis to spatialite, reprojecting to “EPSG:25830”:
ogr = gdaltools.ogr2ogr() conn = gdaltools.PgConnectionString(host="localhost", port=5432, dbname="scolab", schema="data", user="myuser", password="mypass") ogr.set_input(conn, table_name="roads", srs="EPSG:4326") ogr.set_output("mydb.sqlite", srs="EPSG:25830") ogr.execute()
Configuration
By default, gdaltools assumes that Gdal/Ogr commands are installes under /usr/bin/ (the standard Linux path). In order to configure specific paths (for instance for using the library in Windows), you can use:
import gdaltools gdaltools.Wrapper.BASEPATH = "C/Program Files/Gdal/bin" print gdaltools.gdalinfo("mywindowsraster.tif")
You can also use lower level API for setting the full path for specific commands:
info = gdaltools.GdalInfo(command_path="C/Program Files/Gdal/bin/gdalinfo.exe") info.set_input('mywindowsraster.tif') print info.execute() print info.get_raster_stats()
