OTB.OSMDownloader: Download vector data from OSM and store it to file

The application connects to Open Street Map server, downloads the data corresponding to the spatial extent of the support image, and filters the geometries based on OSM tags to produce a vector data file.This application can be used to download reference data to perform the training of a machine learning model (see for instance [1]).By default, the entire layer is downloaded. The application has a special mode to provide the list of available classes in the layers. The downloaded features are filtered by giving an OSM tag 'key'. In addition, the user can also choose what 'value' this key should have. More information about the OSM project at [2].

Inputs

Image used to derive the spatial extent to be requested from OSM server (the bounding box of the extent is used). Be aware that a request with a large extent may be rejected by the server.

format
href
Please set a value for support.

OSM tag key to extract (highway, building...). It defines a category to select features.

string

OSM tag value to extract (motorway, footway...). It defines the type of feature to select inside a category.

string

This parameter allows selecting a directory containing Digital Elevation Model files. Note that this directory should contain only DEM files. Unexpected behaviour might occurs if other images are found in this directory.

string

Use a geoid grid to get the height above the ellipsoid in case there is no DEM available, no coverage for some points or pixels with no_data in the DEM tiles. A version of the geoid can be found on the OTB website(https://gitlab.orfeo-toolbox.org/orfeotoolbox/otb-data/blob/master/Input/DEM/egm96.grd).

format
href
Please set a value for elev.geoid.

This parameter allows setting the default height above ellipsoid when there is no DEM available, no coverage for some points or pixels with no_data in the DEM tiles, and no geoid file has been set. This is also used by some application as an average elevation value.

number
Please set a value for elev.default.

Print the key/value classes available for the selected support image. If enabled, the OSM tag Key (-key) and the output (-out) become optional

boolean
Please set a value for printclasses.
