sepal_ui.aoi.aoi_model.AoiModel#

class sepal_ui.aoi.aoi_model.AoiModel(**kwargs)[source]#

An Model object dedicated to the sorage and the manipulation of aoi.

It is meant to be used with the AoiView object (embedded in the AoiTile). By using this you will be able to provide your application with aoi as an ee_object or a gdf, depending if you activated the ee binding or not. The class also provide insight on your aoi geometry.

Parameters:

gee (bool) – whether or not the aoi selector should be using the EarthEngine binding
vector (str | Path | None) – the path to the default vector object
admin (Unicode) – the administrative code of the default selection. Need to be GADM if ee==False and GAUL 2015 if ee==True.
asset (str | Path | None) – the default asset. Can only work if ee==True
folder (str | Path) – the init GEE asset folder where the asset selector should start looking (debugging purpose)

Deprecated since version 2.3.2: ‘asset_name’ will be used as variable to store ‘ASSET’ method info. To get the destination saved asset id, please use ‘dst_asset_id’ variable.

asset (str | Path | None) – the default asset. Can only work if ee==True
folder (str | Path) – the init GEE asset folder where the asset selector should start looking (debugging purpose)

Return type:

None

Deprecated since version 2.3.2: ‘asset_name’ will be used as variable to store ‘ASSET’ method info. To get the destination saved asset id, please use ‘dst_asset_id’ variable.

AoiModel.clear_attributes()[source]#

Return all attributes to their default state.

Note

Set the default setting as current object.

Return type:: Self

AoiModel.clear_output()[source]#

Clear the output of the aoi selector without changing the traits and/or the parameters.

Return type:: Self

AoiModel.export_to_asset()[source]#

Export the feature_collection as an asset (only for ee model).

Return type:: Self

AoiModel.get_columns()[source]#

List[str]

AoiModel.get_ipygeojson(style=None)[source]#

Converts current geopandas object into ipyleaflet GeoJSON.

Parameters:: style (dict | None) – the predefined style of the aoi. It’s by default using a “success” sepal_ui.color with 0.5 transparent fill color. It can be completely replace by a fully qualified style dictionary. Use the sepal_ui.color object to define any color to remain compatible with light and dark theme.
