I'm a newbie where GIS is concerned, so please don't hesitate to point me to a manual.
We've got DEM files without any projection information. One is called
000426_LO17_200M_BD16_25.ORT and contains lines like the following:
-75925.00 2710900.00 834.88 -75925.00 2710800.00 832.98 -75925.00 2710700.00 830.77 -75925.00 2710600.00 832.38 -75925.00 2710500.00 830.83
So we think this is a LO17 projection, at a 200M DEM spacing, and we're guessing the 3rd column is elevation in m. Given that we know the data is from South Africa (or close to it), this seems about right.
We're trying to get this data into Google Fusion, but need to convert it into a format that Google Fusion will understand, or equivalently, into a gdal format that we can then convert to Google Fusion.
We've tried a gdal_grid conversion, but when attempting to import into Fusion, we get Fusion is complaining about no mapping for TMSO to proj.4
If anybody has any ideas or suggestions, it would be greatly appreciated.
All the best, Craig
