RE: [mapserver-users] CGI-wrapper script on windows / openlayers wmsgetfeatureinfo
I found another answer myself, guess this counts as a bit more elegant than a
cgi-wrapper script ;-)
I use the mod_rewrite in apache, following these three steps:
1) Comment out the mod_rewrite line in httpd.conf
2) Enable mod_rewrite for the actual document root. I am using virtual servers
and added the following lines in the actual section:
Options FollowSymLinks
AllowOverride All
(where "c:\documents and settings\vserver\radioecology" is the htdocs directory
for the relevant virtual server)
2.5 Restart apache
3 make a .htaccess file in the actual directory:
RewriteEngine on
RewriteRule ^wmsmap?(.*)
/cgi-bin/mapserv.exe?map=/documents+and+settings/vserver/radioecology/mobilweb/mobilwms.map&$1
The rewriteRule says: given a webpage starting with wmsmap, pick out the query
parameters, make a new page request starting with
/cgi-bin/mapserv.exe?map=(...)? and add on whatever was the query parameter in
the original page request. ie,
/wmsmap?mode=map will be rewritten to
/cgi-bin/mapserv.exe?map=/documents+and+settings/vserver/radioecology/mobilweb/mobilwms.map&mode=map
Quite simple when one just knows how to do it. I would propose to add something
like the text above to chapter 12.6 A Simple CGI Wrapper Script in the manual -
that would at least have saved me quite some time..

RE: [mapserver-users] PHP MapScript pixel coordinates to map coordinates
Seems like noone have answered this yet... In fact, it is as easy as using proportions. Mapservers mapextent is given in units of the actual projection of the maå.

Here's what I'm trying to do: I have a jQuery-based front-end that uses the wonderful jcrop extension (http://deepliquid.com/content/Jcrop.html) that helps coordinate zoom. I'm hoping to use this same front-end to permit cropping of a resultant map image, which means I need to pass the four pixel corner coordinates, convert to map coordinates (projection may be variable), then set the extent such that the resultant map image will have the same dimensions as that described by the user on the front-end. So, how can I convert pixel coordinates to map coordinates? Note that the map projection is not always DD so I cannot merely use proportions as I have seen in some solutions. Surely this is easier than I am making it out to be.

(the map should be in utm, I would prefer not having to reproject the
measurement locations)
I create a new map object with the layer to be queried, set the projection of
the new map object to the same as the queried layer and then I do a
queryByPoint on the new map object. This works to get find a object. To plot
the query map, I get a unique id for the selected point, do a queryByAttributes
on the corresponding layer in the drawn map.

Josh, Thanks, but could you please elaborate this a bit? Do you mean that you are doing a reprojection in mapscript of the projected layer or that you are projecting the layer 'as saved' before mapserver gets to see i at all? since the query is towards the map object, I cannot see how I can do any more reprojection of the layer, except what has been done when the layer was plotted. -- Morten Sickel Norwegian Radiation Protection Authority -Original Message- From: Josh Hevenor [mailto:jheve...@rogers.com] Sent: Thursday, January 28, 2010 8:42 PM To: Morten Sickel Subject: Re: [mapserver-users] Projection and mapquery I have to wrap my head around this subject every time I come back to it.

I presently have a set up in which I plot some measurements on some background
maps. Things work fine, but I want to add the possibility to query the
measurement data set by clicking on a measurement. The measurements have
coordinates in lat lon and I only manage to query those data if I plot the
entire map in the same projection. I have tried to reproject the query point
using code like
$mapproj=$map->getProjection();
$layerproj=$map->getlayerbyname('mobil')->getProjection();
if($mapproj!=$layerproj){
$mapproj=ms_newProjectionObj($mapproj);
$layerproj=ms_newProjectionObj($layerproj);
debug(array($geopoint->x,$geopoint->y));
$geopoint->project($mapproj, $layerproj);
// projects the point from the projection of the map to the projection
of layer
debug(array($geopoint->x,$geopoint->y));
}
the debug function just dumps the data and it is clear that the point is
correctly reprojected, but anyhow
$map->queryByPoint($geopoint, MS_MULTIPLE, 1);
never gives anything if the mobil-layer and the map are in different
projections.
Are there any ways to overcome this? As I am mostly working on maps from 60 deg
north and upwards, geographical projection is not the projection of choise and
I would prefer not having to reproject the measurement data.

SV: [mapserver-users] Need Help with Custom (Raster) Data as Input
Dear Muizudeen, As far as I understand you,you try to do three things at once - Learn GIS - Learn a new programming tool (mapserver et.al.) - Clean up your existing data All these goals are good to try to achieve, but not at once. Most of all, when starting to learn GIS and starting to learn mapserver, you should be sure that the data you are using are of good quality, i.e. at least well defined projection and geo references, if that is not correctly set up, What I would recommend you to do is to start up using some other available data sets of the same type as what you are using (geo tiffs, or whatever) Set up a map server application using those data sets, read up on projections and geo referencing, try to find some other data sets covering the same area as the first you got, but in other projections, play around a bit with those data, also changing the projection of the map-file. This way you know that what you are doing in map server makes sense. parallell with this, you can try to collect the nessecary information on the other maps you have, and make a new map-file using those data sets. If the maps are scanned files, they can be made into geo-tiffs, ie a tiff file and a corresponding tfw file, the latter giving the coordinates for one of the corners of the map, the cell size and the rotation angle of the map, I don't remember the details at the moment, but that should be quite easy to google for. best wishes.

As I am doing a lot of mapping of marine areas, I want to use the etopo dataset as a backdrop, but something goes terribly wrong when I try to project it. In my mapfile, I have defined the extent and projetion as: EXTENT -80 -150 85 130 #LAEA UNITS METERS PROJECTION "proj=laea" # "lat_0=70" "lon_0=15" END And the etopo dataset is fetched as: LAYER PROJECTION "init=epsg:4326" END NAME Etopo2 TYPE RASTER OFFSITE 0 0 0 STATUS ON CONNECTIONTYPE WMS CONNECTION "http://map.ngdc.noaa.gov/servlet/com.esri.wms.Esrimap?servicename=Deck41"; METADATA "wms_srs" "EPSG:4326" "wms_name" "MODIS/ETOPO2 Relief" "wms_server_version" "1.1.0" "wms_format" "image/jpeg" END END # Etopo2 WMS image ends here What I end up with then can be seen in http://radioecology.info/images/etopo_laea.png (the red lines are administrative borders in Norway) if I make the same map without projection, it ends up like http://radioecology.info/images/etopo_geo.png (the borders are supposed to extend a bit out into the sea) If I try to ue the topographical gtopo map, I fetch it with etop LAYER NAME GTOPO TYPE RASTER OFFSITE 0 0 0 STATUS OFF CONNECTIONTYPE WMS CONNECTION "http://imsref.cr.usgs.gov:80/wmsconnector/com.esri.wms.Esrimap/USGS_EDC_Elev_GTOPO?"; METADATA "wms_srs" "EPSG:4326" "wms_name" "GLOBAL.GTOPO60_COLOR_RELIEF" "wms_server_version" "1.1.1" "wms_format" "image/jpeg" END PROJECTION "init=epsg:4326" END END And I get http://radioecology.info/images/gtopo_laea.png which looks just right. Any Idea of what goes wrong? The etopo dataset obiously gets projected, but I have no idea about how, I have also tried a few other projections, getting the same result, etopo freaking out, gtopo working nicely... Have anyone had any success in reprojecting etopo? Are there any other wms sources I can use? (Of cource, I can download the tiles I need and reproject and mess around with them as I like to, but it would also be useful to be able to use the etopo wms server.
