Hi,<br><br>I am trying to determine the EPSG code from a gdalinfo listing against a mrSid file of raster data within Florida and I get the following error when running gdalinfo:<br>"Warning 4: Unable to find state plane zone in stateplane.csv, likely because the GDAL data files cannot be found. Using incomplete definistion of state plane zone"<br>
<br>Based on the (incomplete) listing below I looked into the epsg file contained within MapServer and I found a few possiblities for the epsg code:<br><br>1.)<br> # NAD83 / Florida East<br><26958> +proj=tmerc +lat_0=24.33333333333333 +lon_0=-81 +k=0.999941 +x_0=200000 +y_0=0 +ellps=GRS80 +datum=NAD83 +units=m +no_defs no_defs <><br>
<br>or <br><br>2.) <br> # NAD 1983 HARN StatePlane Florida East FIPS 0901<br><102258> +proj=tmerc +lat_0=24.33333333333333 +lon_0=-81 +k=0.999941 +x_0=200000 +y_0=0 +ellps=GRS80 +units=m no_defs <> <br><br>
or<br><br>3.)<br> # NAD83(HARN) / Florida East<br><2777> +proj=tmerc +lat_0=24.33333333333333 +lon_0=-81 +k=0.999941 +x_0=200000 +y_0=0 +ellps=GRS80 +towgs84=0,0,0,0,0,0,0 +units=m +no_defs no_defs <><br><br>
<br>Which one of above 3 should I use for both processing imagery within gdalwarp and reprojecting on the fly within mapserver?<br><br>Thanks,<br><br>John<br><br>Below is the listing that gdalinfo generated. <br>
