srs Property that returns the SpatialReference associated with this layer:

difference() Returns the region consisting of the difference of this geometry and the other, as a new OGRGeometry

min_x The value of the minimum X coordinate.

extent Extent (boundary values) of the raster source, as a 4-tuple (xmin, ymin, xmax, ymax) in the spatial reference

from_esri() Morphs this SpatialReference from ESRI’s format to EPSG

width The width of the source in pixels (X-axis). >>>

num_coords Alias for point_count.

wkt Returns the WKT representation of this spatial reference.

geom_type Returns the geometry type of the layer, as an OGRGeomType object:

validate() Checks to see if the given spatial reference is valid, if not an exception will be raised.
