Topaz to shape file conversion

Recommended Posts

Dear All

How can i conver/save/import the TOPAZ file of WMS to shape/coverage file format used in GIS??

Thanks

Dear Sheraz,

perhaps you can create the stream arc first, and then save the feature arc as a shape file. to create the stream arc, we can use DEM module, create some outlet points, and convert DEM to stream arc.

otherwise, you can also create the basin and save the result (feature arc in shapefile).

i hope that helps

any comment?

Sheraz,

Ida is right. You can't convert the TOPAZ output file directly to a shapefile because it's not vector data, it's raster data. If you convert your flow accumulations to stream arcs, you will be able to export these arcs as a shapefile. Also, after you have created stream arcs, you can export your flow direction and flow accumulation grids as Arc/Info ASCII raster grids that can be imported into ArcGIS. To do this, go to the map module after creating your stream arcs, then select File | Save As..., then select the option to export an ArcView/WMS Superfile (*.sup). Save the flow direction and flow accumulation grids. WMS will save these grids as Arc/Info ASCII grids and you can import these grids into any version of ArcGIS.
