[Qgis-user] Info: how get raster extent (xmin, xmax, ymin and ymax)

[Matt Wilkie]

Hi Filippo,

    raster = gdal.Open(src_raster)
    georef = raster.GetGeoTransform()
    xmin, ymax = georef[0], georef[3]

Will work for a regular north-to-top image. More details at
http://www.gdal.org/gdal_tutorial.html under "Getting Dataset Information"
heading.

If you need to get extent of data, e.g. strip the nodata collar, have a
look at
http://gis.stackexchange.com/questions/45159/finding-minimum-bounding-extent-of-given-pixel-value-within-raster/
.

cheers,

Matt
