Interface ExternalGeospatialRasterReader

public interface ExternalGeospatialRasterReader

Interface to encapsulate geospatial data lookup implementations for raster files. Some tests like ElevationErrorTest need to read geospatial raster data. This interface was designed to decouple tests from specific implementations that can perform these operations.

Since tests need to dynamically instantiate them, their constructors should not require any parameters.
