Felix, Extent defines the bounding box that you want do display as a default for your map. The values need to be expressed in the same units as your output spatial reference system. (e.g. if your data is in decimal degrees of lat/long, your extent should be in decimal degrees). The format is [minimum x value] [minimum y value] [maximum x value] [maximum y value] . UNITS also needs to reflect the units of your output SRS. Try: EXTENT -73.795132 40.685928 -74.153979 40.846823 UNITS dd Unless you are calling the layer by name in the URL request, change STATUS to DEFAULT to ensure that the layer shows up. David.

I've setup the latest version of MapServer and I have a TIF with a TFW file. I don't fully understand how EXTENT works, and I can't find any decent explanation in the documentation. I'm trying to display a portion of my map based on latitude and longitude. What do I need to put in my EXTENT field so that I can get a map with top-left (40.846823/-74.153979) and bottom-right (40.685928/-73.795132). Thank you for any assistance! Felix Here is my TFW file: 63.545941999999989 0.0 0.0 -63.545941999999989 -421692.82776298042 -15874.371420191659 And my Map File: MAP NAME NY77SOUTH STATUS ON IMAGETYPE PNG SIZE 500 500 SHAPEPATH "/var/www/html" #West South East North EXTENT -421692.82776298042 -15874.371420191659 0 0 UNITS METERS PROJECTION "proj=lcc" "lat_1=46.666667" "lat_2=41.333333" "lon_0=-72.833333" "lat_0=42.1" "x_0=0.0" "y_0=0.0" "ellps=GRS80" "datum=NAD83" END WEB IMAGEPATH "/var/www/html/tmp/" IMAGEURL "/tmp/" END LAYER NAME "chart" TYPE RASTER STATUS ON DATA "/var/www/html/NewYork77South.tif" END END
