Hello Group, I have been working with the MapFish user groups helping me build http://webmap.rthicksconsult.com. I followed many discussions on EPSG 900913 and EPSG 3785 on the OpenLayers group and believe that the OpenLayers community may be able to help me.
I am in the process of projecting all layers to EPSG 900913 (spherical mercator) so that my WMS layers align with google base layers. So far, the Geology, Amigo, and Water Wells layers align fine. I also got the google geocoder to center the map properly. But I am having difficulty getting the search marker and USGS topographic map layers to display. The projected web map with the PROBLEMS is at http://webmap.rthicksconsult.com/index_prj.html The ORIGINAL unprojected web map (the original map that displays topos and site marker) is at http://webmap.rthicksconsult.com I am not sure if the issue is in my MapServer map file, the map.addLayer(), or somewhere else. The MapServer mapfile which generates the marker for the search is reproduced below. I passed the lat/long variable both in epsg 900913 and 4326, this made no difference. I also have an alert box pop up to verify the coordinate transformation when the submit to location button is activated. I also included portions of the mapfile that renders my layers for the projected web map. The USGS Topo layer is servered directly from TerraServer via WMS. The USGS Topo2 layer is servered from MapServer via TerraServer. Topo and Topo2 render in the unprojected state. Thank you for the help. ~andrew parker PS: I am using this site for guidance: http://docs.openlayers.org/spherical_mercator/ radius_prj.map called by ggeocoder_prj.js #******************************************** NAME "Radius" STATUS ON SIZE 800 800 IMAGECOLOR 255 255 255 IMAGETYPE PNG OUTPUTFORMAT NAME "png" MIMETYPE "image/png" DRIVER "AGG/PNG" EXTENSION "png" IMAGEMODE RGBA TRANSPARENT on END OUTPUTFORMAT NAME "gif" MIMETYPE "image/gif" DRIVER "GD/GIF" EXTENSION "gif" TRANSPARENT on END UNITS meters PROJECTION "init=epsg:26910" END SYMBOLSET "symbols.sym" WEB IMAGEPATH "/maps/images.tmp/" IMAGEURL "/images.tmp/" METADATA "wms_title" "mapfile" "wms_onlineresource" "http://216.93.173.156/cgi-bin/mapserv?map=radius_prj.map"; "wms_srs" "EPSG:4269 EPSG:4326 EPSG:900913 EPSG:3785" END END LAYER NAME "groundzero" TYPE point CONNECTIONTYPE postgis CONNECTION "user=**** dbname=***** password=***** host=localhost" METADATA WMS_SRS 'epsg:4326" WMS_TITLE 'groundzero' # WMS_FEATURE_INFO_MIME_TYPE 'text/html' END #METADATA # the data is a dynamically constructed point, wherever they specified DATA "the_geom from (SELECT 1 as gid,transform(GeometryFromText('POINT(%centerx% %centery%)',4326),26910) as the_geom) as foo using unique gid using srid=26910" CLASS STYLE SYMBOL "/maps/data/marker.png" END END END END # end of mapfile #************************************************* projection.map #*********************************************** NAME "R.T.
