width The width of the source in pixels (X-axis). >>> GDALRaster({'width': 10, 'height': 20, 'srid': 4326}).width 10

warp(ds_input, resampling='NearestNeighbour', max_error=0.0) New in Django 1.9. Returns a warped version of this raster. The warping parameters can be specified through the ds_input argument. The use of ds_input is analogous to the corresponding argument of the class constructor. It is a dictionary with the characteristics of the target raster. Allowed dictionary key values are width, height, SRID, origin, scale, skew, datatype, driver, and name (filename). By default, the warp functions k

transform(srid, driver=None, name=None, resampling='NearestNeighbour', max_error=0.0) New in Django 1.9. Returns a transformed version of this raster with the specified SRID. This function transforms the current raster into a new spatial reference system that can be specified with an srid. It calculates the bounds and scale of the current raster in the new spatial reference system and warps the raster using the warp function. By default, the driver of the source raster is used and the name

srid New in Django 1.10. The Spatial Reference System Identifier (SRID) of the raster. This property is a shortcut to getting or setting the SRID through the srs attribute. >>> rst = GDALRaster({'width': 10, 'height': 20, 'srid': 4326}) >>> rst.srid 4326 >>> rst.srid = 3086 >>> rst.srid 3086 >>> rst.srs.srid # This is equivalent 3086

srs The spatial reference system of the raster, as a SpatialReference instance. The SRS can be changed by setting it to an other SpatialReference or providing any input that is accepted by the SpatialReference constructor. >>> rst = GDALRaster({'width': 10, 'height': 20, 'srid': 4326}) >>> rst.srs.srid 4326 >>> rst.srs = 3086 >>> rst.srs.srid 3086

skew Skew coefficients used to georeference the raster, as a point object with x and y members. In case of north up images, these coefficients are both 0. >>> rst = GDALRaster({'width': 10, 'height': 20, 'srid': 4326}) >>> rst.skew [0.0, 0.0] >>> rst.skew.x = 3 >>> rst.skew [3.0, 0.0]

scale Pixel width and height used for georeferencing the raster, as a as a point object with x and y members. See geotransform for more information. >>> rst = GDALRaster({'width': 10, 'height': 20, 'srid': 4326}) >>> rst.scale [1.0, -1.0] >>> rst.scale.x = 2 >>> rst.scale [2.0, -1.0]

height The height of the source in pixels (Y-axis). >>> GDALRaster({'width': 10, 'height': 20, 'srid': 4326}).height 20

driver The name of the GDAL driver used to handle the input file. For GDALRasters created from a file, the driver type is detected automatically. The creation of rasters from scratch is a in-memory raster by default ('MEM'), but can be altered as needed. For instance, use GTiff for a GeoTiff file. For a list of file types, see also the GDAL Raster Formats list. An in-memory raster is created through the following example: >>> GDALRaster({'width': 10, 'height': 10, 'srid': 4326}).dri

origin Coordinates of the top left origin of the raster in the spatial reference system of the source, as a point object with x and y members. >>> rst = GDALRaster({'width': 10, 'height': 20, 'srid': 4326}) >>> rst.origin [0.0, 0.0] >>> rst.origin.x = 1 >>> rst.origin [1.0, 0.0]
