An intensity file provides the data - values and units - of the intenity that we want to read on the locations of the exposure model.
At the moment the following formats are supported by the default deus:
- earth quake shakemaps with regular grids
- tsunami shakemaps with irregular grids
To support other formats in the future we introduced an interface for getting the intensity values.
It follows to implement the get_nearest method, so that you can give
it the lon and lat values.
All implementations should give back two dicts with the intensity values and the units of all the fields that are included in the file.
intensities, units = intensity_provider.get_nearest(lon=lon, lat=lat)In case of the earth quake shakemap implementation the keys in the dicts are pga and stdpga (for the standard derivation).
You can use classes from the rasterwrapper module togehter with the RasterIntensityProvider implementation from the intensityprovider module, to access raster cells.
