USGS GeoTiffs will not resample

Recommended Posts

Anyone else have any problem resampling USGS GeoTiff files? I have seen where other users have done this with no problem. I downloaded in my area a corner of an urban area and supposedly USGS sends you a GeoTiff file, but when I resample I get the error:GeoTIFF: Only geographic coordinates are supported.Unable to open data source 'C:DownloadFSX91872578SourceData91872578.tif'.Failed to create data source.Thanks,Wes

Hi Wes,that's probably because the USGS high-res orthos (as all data on the seamless data server) are in UTM projection and NAD83 datum: http://seamless.usgs.gov/website/seamless/...s/highortho.aspResample requires lat/long (geographic) "projection" with WGS84 datum so you need to transform the source data first. There's been a bunch of discussions about suitable tools in this forum and elsewhere and the search engine should help you find them.Cheers, Holger
