If you are able to create a tile index and it looks alright when viewed in a gis application (open ev, arcgis etc..) then I would check out the name of the field containing the paths (and the paths as well) to the images. In my experiance gdaltindex creates a field named "location" not "Location". If you want to check your extent use ogrinfo on your tile index.
ogrinfo -al -so thm_dir.shp I hope this helps Travis -----Original Message----- From: UMN MapServer Users List [mailto:[EMAIL PROTECTED] Behalf Of Ryan Ollerenshaw Sent: Friday, June 30, 2006 4:10 PM To: [email protected] Subject: [UMN_MAPSERVER-USERS] Image tilling What I am trying to do is to georeference aerial photos of a large area, eventually the entire earth. 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
