Class UsgsShakeMapReader

java.lang.Object
nz.org.riskscape.usgs.UsgsShakeMapReader
Direct Known Subclasses:
UsgsShakeMapMultiDatasetReader
public class UsgsShakeMapReader extends Object

Helper to read a datasets from an USGS shakemap file (e.g. shake_result.hdf) and turn it into a spatial coverage. Shakemaps are slightly different to other HDF5 files in that the lat/long coordinates aren't present in a dataset, but instead the bounds/extent of the data is encoded as HDF5 attributes as part of the dataset, i.e. xmin, xmax, ymin, ymax.
