Spatial filtering

Description

In general this transformation should be applicable to models that contain spatially referenced data. As of 03-08-2020, only gridded models (such as from a dfs2 or netcdf file) can be filtered. The transformation allows users to select only a subset of the spatial domain for further processing. In case of gridded data, the result of the filter is again a grid (the envelope/bounding box of the input geometry is applied).

This request to /api/conversion/upload-convert

REST APISDK

{
  "readerName": "<reader name>",
  "writerName": "<writer name>",
    ...
  "transformations": [
    {
        type: "SpatialFilterTransformation",
        spatialFilter: {
            geometry: '<wkt of a geometry>'
        }
    }
  ]
}

var transferResult = await transferClient
            .CreateFileImport(projectId, "<local file>")
            ...
            .WithSpatialFilteringTransformation("<wkt of a geometry>")
            ...
            .ExecuteAsync();

will only select the grid that is contained within the specified geometry.
