GeoDatabase
gma.gio.GeoDatabase
[class] GeoDatabase(data = None, driver = None, out_dst = None):Initialize a GeoDatabase object.
**Optional:
data = None||str. Default None.
If None, create a new empty GeoDatabase. If str, open the file path as GeoDatabase.
driver = str||None. Default None.
If data is None, the driver name to create the GeoDatabase.
out_dst = str||None. Default None.
If data is None, the output file path to create the GeoDatabase.
Method
add_layer
[method] .add_layer(layer, new_name = None, over_write = False, **kwargs):
Add Layer to GeoDataBase.
Parameters:
GMALayer: Layer.
Another GMA Layer!
**Optional:
new_name = str||None. Default None.
The new name of the added Layer. Default is the added Layer's name.
OverWrite = bool. Default False.
Whether to force overwrite the layer with the same name.
create_layer
[method] .create_layer(name = None, crs = None, gtype = "Polygon", options = {}):
Create a new layer in GeoDatabase.
**Optional:
name = str||None. Default None.
The name for the new layer. This should ideally not match any existing layer on the datasource. None for randint.
crs = int||str||CoordinateReferenceSystem. Default None.
The coordinate system to use for the new layer, or None if no coordinate system is available.
gtype = int. Default 'Polygon'.
Geometry type for the layer. Use 'Polygon' if there are no constraints on the types geometry to be written.
options = dict||list. Default [].
Driver-specific dict or list of `name=value` options.
Returns:
Type: Layer.
delete_layer
[method] .delete_layer(name_or_id):
Delete a Layer in GeoDataBase.
Parameters:
name_or_id: int||str.
Layer name or ID in GeoDataBase!
get_dataset
[method] .get_dataset(name_or_id = 0):
Get a Dataset in GeoDataBase.
**Optional:
name_or_id = int. Default 0.
Dataset ID or name in the GeoDataBase to get.
Returns:
Type: Dataset.
get_layer
[method] .get_layer(name_or_id = 0):
Get a Layer in GeoDatabase.
**Optional:
name_or_id = int||str. Default 0.
Layer id or name in the GeoDatabase to get.
Returns:
Type: Layer.
iteritems
[method] .iteritems(category = None, **kwargs):
Iterate vector layers and raster datasets. --> iter
query
[method] .query(expr, tran_opts = {}, **kwargs):
Query the vector Layer with a SpatiaLite SQL expression.
Parameters:
expr: str.
The sql(ite) query string to evaluate.
**Optional:
tran_opts = dict. Default {}.
Other parameters passed to ._aio.layer.vector_translate.
**kwargs:
Other parameters passed to ._aio.vrt.VRTGeoDatabase.add_file.
Returns:
Type: Layer.
