TUFLOW Message 0305: Difference between revisions

|message_desc=By default, TUFLOW checks that the projection in each '''.shp''' or '''.mif''' file matches that specified in the SHP Projection == or MI Projection == command, respectively. This ensures that incoming files are in the same projection as the TUFLOW model. TUFLOW is not a GIS software and does not use the projection information in each file (apart for the check). TUFLOW uses the co-ordinates of the objects in the GIS layer and locates them in the TUFLOW model. Hence the need for a projection check. All model input files should be in the same projection, if inputs are not in the correct projection the data will be in the wrong location and won't be used. If your model is in (for example) MGA 94 zone 56, and the 2d materials (2d_mat) file is in the wrong projection (e.g. NSW ISG 56/1), these material regions (polygons) will be in the wrong location (probably in the middle of the ocean) and they won't be assigned to any model cells.<br>

This checkmessage prevents problems with the data provided having a different projection than the TUFLOW model.<br><br>
