[mapserver-users] a follow-up to REST services in MapServer

[Eric Weisbender]

What I have learned sense my last post on REST/WMTS in MapServer is that ArcOnline REST services are known as WMTS or web map tile services and with GDAL 1.7 or better you can use an xml proxy file in conjunction with gdal to access any WMTS.  With this configuration the WMTS behaves like any WMS.  Speed and performance is comparable to WMS but resolution is sometimes iffy.  My layer def and gdal xml file is as follows.  Thanks to Robert, Mark, and others .
 
LAYER
    NAME "esri_imagery"
 TYPE RASTER
 STATUS OFF
 DATA "/data/gis/www/html/cso/esri_imagery.xml"
 PROCESSING "OVERSAMPLE_RATIO=1.0"
   METADATA
  "wms_title"     "World_Imagery"
  "wms_name"      "World_Imagery"
  "wms_srs"       "EPSG:3785"
   END
  PROJECTION
     "init=epsg:3785"
    END
  CLASS
      NAME "ESRI Imagery"
      KEYIMAGE "/data/gis/www/html/ms_common/colorphoto_sym.png"
    END
END
