ArcGIS is enabled for listening to grid events as long as the lightening bolt is enabled on the OpenSprit toolbar and the "GIS Grid Event " option is chosen in the options dialog:
When a grid event is received a new raster feature will be created and added to the map with a default rainbow color scale:
The raster feature will be written to disk as an IMAGINE image in a working directory specified in the OpenSpirit options dialog (default in the users home directory):
The created raster feature will have the CRS as set on the grid event by the sending application. If the raster feature CRS has a datum that differs from the current map display CRS datum and a suitable transform is not already set in the ArcGIS project, the user is prompted to select a transform from a list based on the EPSG database used by the OpenSpirit coordinate service. If the CRS has a list of fall-back transforms, the user will be prompted to select one to use; otherwise, the preferred transform on the CRS will be set on the ArcMap map. Tthe details of the EPSG parameters may be shown in order to help guide this transform selection.
