Required Arguments
`datasource` => string or DataSource object to file pointer
`model name` => string of name of new model class to create
Optional Keyword Arguments
`geom_name` => For specifying the model name for the Geometry Field.
Otherwise will default to `geom`
`layer_key` => The key for specifying which layer in the DataSource to use;
defaults to 0 (the first layer). May be an integer index or a string
identifier for the layer.
`srid` => The SRID to use for the Geometry Field. If it can be determined,
the SRID of the datasource is used.
`multi_geom` => Boolean (default: False) - specify as multigeometry.
`name_field` => String - specifies a field name to return for the
`__unicode__` function (which will be generated if specified).
`imports` => Boolean (default: True) - set to False to omit the
`from django.contrib.gis.db import models` code from the
autogenerated models thus avoiding duplicated imports when building
more than one model by batching ogrinspect()
`decimal` => Boolean or sequence (default: False). When set to True
all generated model fields corresponding to the `OFTReal` type will
be `DecimalField` instead of `FloatField`. A sequence of specific
field names to generate as `DecimalField` may also be used.
`blank` => Boolean or sequence (default: False). When set to True all
generated model fields will have `blank=True`. If the user wants to
give specific fields to have blank, then a list/tuple of OGR field
names may be used.
`null` => Boolean (default: False) - When set to True all generated
model fields will have `null=True`. If the user wants to specify
give specific fields to have null, then a list/tuple of OGR field

2,546 | geometries.py | gabrielfalcao_lettuce/tests/integration/lib/Django-1.3/django/contrib/gis/gdal/geometries.py | """
The OGRGeometry is a wrapper for using the OGR Geometry class
(see http://www.gdal.org/ogr/classOGRGeometry.html). OGRGeometry
may be instantiated when reading geometries from OGR Data Sources
(e.g. SHP files), or when given OGC WKT (a string).
While the 'full' API is not present yet, the API is "pythonic" unlike
the traditional and "next-generation" OGR Python bindings. One major
advantage OGR Geometries have over their GEOS counterparts is support
for spatial reference systems and their transformation.
Example:
>>> from django.contrib.gis.gdal import OGRGeometry, OGRGeomType, SpatialReference
>>> wkt1, wkt2 = 'POINT(-90 30)', 'POLYGON((0 0, 5 0, 5 5, 0 5)'
>>> pnt = OGRGeometry(wkt1)
>>> print pnt
POINT (-90 30)
>>> mpnt = OGRGeometry(OGRGeomType('MultiPoint'), SpatialReference('WGS84'))
>>> mpnt.add(wkt1)
>>> mpnt.add(wkt1)
>>> print mpnt
MULTIPOINT (-90 30,-90 30)
>>> print mpnt.srs.name
WGS 84
>>> print mpnt.srs.proj
+proj=longlat +ellps=WGS84 +datum=WGS84 +no_defs
>>> mpnt.transform_to(SpatialReference('NAD27'))
>>> print mpnt.proj
+proj=longlat +ellps=clrk66 +datum=NAD27 +no_defs
>>> print mpnt
MULTIPOINT (-89.999930378602485 29.999797886557641,-89.999930378602485 29.999797886557641)
The OGRGeomType class is to make it easy to specify an OGR geometry type:
>>> from django.contrib.gis.gdal import OGRGeomType
>>> gt1 = OGRGeomType(3) # Using an integer for the type
>>> gt2 = OGRGeomType('Polygon') # Using a string
>>> gt3 = OGRGeomType('POLYGON') # It's case-insensitive
>>> print gt1 == 3, gt1 == 'Polygon' # Equivalence works w/non-OGRGeomType objects

This module houses ctypes interfaces for GDAL objects. The following GDAL
objects are supported:
CoordTransform: Used for coordinate transformations from one spatial
reference system to another.
Driver: Wraps an OGR data source driver.
DataSource: Wrapper for the OGR data source object, supports
OGR-supported data sources.
Envelope: A ctypes structure for bounding boxes (GDAL library
not required).
OGRGeometry: Object for accessing OGR Geometry functionality.
OGRGeomType: A class for representing the different OGR Geometry
types (GDAL library not required).
SpatialReference: Represents OSR Spatial Reference objects.
The GDAL library will be imported from the system path using the default
library name for the current OS. The default library path may be overridden
by setting `GDAL_LIBRARY_PATH` in your settings with the path to the GDAL C
library on your system.
GDAL links to a large number of external libraries that consume RAM when
loaded. Thus, it may desirable to disable GDAL on systems with limited
RAM resources -- this may be accomplished by setting `GDAL_LIBRARY_PATH`
to a non-existant file location (e.g., `GDAL_LIBRARY_PATH='/null/path'`;
setting to None/False/'' will not work as a string must be given).

Permissions are set globally per type of object, not per specific object instance.
