Converting Geobase Land Cover Data
I have GML polygon files of canada land cover data that I want converted to a grid format like asci grid or similar. I found a thread that recommended coloring polygon areas based on land cover code. I used a palette that only had the R value of RGB defined for each palette id(23 ids), I set the R value to the land cover type code which range from 0-233. I then exported a single band BIL file(r band), then reimport that BIL and click yes that it is Elevation data. The file imports but the R values are not imported correctly as terrain values like it should (i have used this method to convert USGS Land cover data in a similar way and it imports the R values correctly). The elevation goes from -45 to 122. I can't figure out where these numbers are coming from...any reasons you can think of?
