Hello all,
I have model data that was converted to a raster from an ASCII file. This dataset covers essentially the eastern 1/3 of the CONUS, Because this data has a set spatial resolution (12km) I used UTM coordinates and meters for units in the ASCII header. The problem comes when attempting to project this data. When comparing the model output and a US shapefile, the data does not appear to be projected properly as the coastlines do not match up. The reference point used to convert the text file is in UTM, however the coordinate system is still unknown.
I am no expert in GIS or map projections by any means, however my thought was that I should define the projection in the UTM zone that the lower-left corner is located (since my starting points were in UTM and my cellsize is in meters). Does this seem reasonable or is there another step that needs to happen to project the data properly?
Thanks,
Steve
