TransDEM Forum

Hi Phil,

Having a problem with downloaded Tiff files of NZ.

Trying to open up in TransDem I get following error :-

ProjectedCSTypeGeoKey tag value unknown (PCS_GD49_NZ_MAP_GRID)

Any help would be appreciated.

I'm still on holidays and not able to really analyse this issue right now. But I will need more information anyway. Which version of TransDEM are you using? And what kind of geo data source are you trying to load, i.e. from which website?

Typical GeoTIFF issues are map projections or projection parameters unknown to TransDEM or a projection encoding which TransDEM does not understand.

Hi Phil,
Sorry, forget about the above as after reading the "resources" section of the forum, under New Zealand, I see that on 27th April 2011 you successfully got ASCII Grid to work whereas I was downloading Tiff files. All systems are now go.
