Ryan, There may be additional issues, but if you are not explicitly calling this layer by name in the URL or post request, you need to set the layer status to DEFAULT to make the layer visible.

So what I need is to be able to specify the lat/long of each photo (which I have) using only the lat/long coordinate system. I would like the user to be able to specify a bounding box (lat/long) for a given area then have my mapserver return all the available images for that given area. Currently I think that I can use: gdal_translate -a_ullr 180 0 210 -30 thm_dir_N-30_180.png thm_dir_N-30_180.tiff To georeference all of my photos, then: gdaltindex thm_dir.shp *.tif To create a shape file with an index of all the photos, then I can specify my layer in the mapfile as: LAYER NAME "tileindex" STATUS ON TILEINDEX "thm_dir.shp" TILEITEM "Location" TYPE RASTER END But when I display this layer in MapServer I get a blank image, and when I try to view the shape file in ArcMap I can see my tiles but they are just displayed as blank polygons with no images. I think that my problem is incorrectly specifying the EXTENT in the map file, but i am not sure what i should put if i want my tiles to eventually cover then entire world. Thanks, -Ryan Here is my entire map file incase that helps any: NAME WMSDEMO STATUS ON SIZE 500 400 #EXTENT 0 0 2800 2800 #EXTENT -180 -90 180 90 EXTENT -9200000 -912631 3072800 3840000 #UNITS METERS SHAPEPATH "../data" IMAGECOLOR 255 255 255 WEB TEMPLATE test_template.html IMAGEPATH "/tmp/ms_tmp/" IMAGEURL "/ms_tmp/" METADATA WMS_TITLE "WMS test mapserver" WMS_ACCESSCONSTRAINTS "none" #WMS_ONLINERESOURCE "http://neuron/cgi-bin/mapserv?map=display.map&"; WMS_SRS "EPSG:4326" #"AUTO:42003" END END PROJECTION "init=epsg:4326" END LAYER # Shaded Relief Raster NAME test_layer DATA bath_mapserver.tif STATUS ON TYPE RASTER END LAYER NAME "hpool" STATUS ON #DATA "thm_dir_00_030.tiff" TILEINDEX "thm_dir.shp" #TILEITEM "Location" TYPE RASTER END END # of map file
