Hi, Obviously your EXTENT and your layer projections do not match. Either use EXTENT values in epsg:26914 (you can check suitable values for your layer with ogrinfo). However, if you want to reproject the data and have output in lat/lon then you must set projection for MAP level as well. EXTENT tells the map area in output projection.

Can you help me? Thanks, Albert "Fawcett, David" <[EMAIL PROTECTED]> wrote:Message Albert, Projection in MapServer isn't handled with an external file, like in ArcMap. It is done in the map file. Take a look at the Mapfile documentation to see how to do projection. http://mapserver.gis.umn.edu/docs/reference/mapfile/projection/view You need to define a projection block in the MAP block of the map file, this is set to the projection that you want your data output in. You would then define a projection block in each layer, this is set to the projection that the original data for that layer is in. It is easiest to use epsg codes, look at example 2 in the link above. The epsg code for UTM zone 14N nad83 is 26914 and 4326 can be used for you lat/long data.

Hi, I was using a projection file UTM Zone 14n Nad_83. Then I switch to an unprojective file and I saw my data show up. What would be the first best step for setting a projection file? Thanks Albert "Fawcett, David" <[EMAIL PROTECTED]> wrote: You may want to take a look at your extent. Do you really intend to show a primarily empty stretch of the northern Atlantic Ocean (apologies to Canary Islanders...)? You are telling MapServer that your map area is contained within a box from 50 deg. west longitude to 10 deg. west longitude and 20 to 90 degrees north latitude. If the name of your mapfile relates to the data, I am guessing that Richland County isn't in this box. Use ogrinfo or a desktop GIS app to look at the extent of your data. Also, the extent needs to be in the units of the spatial reference system that your data is in.
