Can I use QGIS for a model originally developed in MapInfo? The answer is, yes.
TUFLOW models can use a combination of MapInfo MIF/MID and QGIS SHP files. The existing MapInfo files can be left in their current form and new updates can be added using SHP format.
Follow these steps:
-
<il> Familarise yourself with the projection of the MapInfo files used by the model.
<
- Use the same projection as MapInfo files and add SHP Projection == ..\model\gis\Projection.prj to the MI Projection command. Both should be included in the model.
- Replace GIS Format == MIF with GIS Format == SHP. This will apply to check files and results.
- Create empty TUFLOW files with Write Empty GIS Files == ..\model\gis\empty. These will automatically generate SHP format files when GIS Format == SHP is specified.
- Exporting MIF files to shapefiles.
- Copying MIF features (points, lines and polygons separately) into a TUFLOW empty file in shapefile format.
