as_double() Returns the value of the field as a double (float):

class Field name Returns the name of this field:

disjoint(other) Returns True if this geometry is spatially disjoint to (i.e. does not intersect) the other, otherwise

num_fields Returns the number of fields in the layer, i.e the number of fields of data associated with each feature in the layer:

class Envelope(*args) Represents an OGR Envelope structure that contains the minimum and maximum X, Y coordinates for a rectangle

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

driver_count Returns the number of OGR vector drivers currently registered.

fields Returns a list of the names of each of the fields in this layer:

min_y The value of the maximum X coordinate.

num_fields Returns the number of fields of data associated with the feature. This will be the same for all features in a given
