[mapserver-users] Mapserver wms and Openlayers 3
Hope you can guide me in this issue I have. My aim is to connect to a Postgis database from Openlayers 3 using Mapserver WMS. Apparently all is set up in my mapfile for WMS service(postgres connection inside). I have tested and validated the getmap request, no errors found. Here is my URL: http://localhost/cgi-bin/mapserv.exe?map=C:/ms4w/Apache/htdocs/maquetado/mapfiles/demo3.mapSERVICE=WMSVERSION=1.1.1REQUEST=GetMapLAYERS=agave_01_gcs,agave_02_gcsSTYLES=SRS=EPSG:4326BBOX=-103.809,20.8419,-103.716,20.8878WIDTH=105HEIGHT=22FORMAT=image/png After that I change the path inside the http.conf file as follows: SetEnv myMap C:/ms4w/Apache/htdocs/maquetado/mapfiles/demo3.map Here is my final URL: http://localhost/cgi-bin/mapserv.exe?map=myMap I have tested it in GIS clients as a QGIS and ArcGIS and all is ok but when I try to use it in OL3 no layers are shown. I think that probably something is wrong with my WMS url that OL3 can not read.. So it is possible to change the mapserv.exe in my URL specifically omit the exe ?? I need something like this: http://localhost/cgi-bin/mapserv?map=myMap Best regards Jordan -- View this message in context: http://osgeo-org.1560.x6.nabble.com/Mapserver-wms-and-Openlayers-3-tp5216956.html Sent from the Mapserver - User mailing list archive at Nabble.com. ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users
Re: [mapserver-users] Heatmap / choropleth from points attributes
First, you have to turn your points into shapes, theres some algorithm that will turn points into polygons with borders midway between each point. Then, you have to add classes to the mapfile. Add one class per color. You have to calculate the bounds and color for each class like this: CLASS EXPRESSION(([POPULATION] gt 90457) AND ([POPULATION] le 108397)) STYLE COLOR 10 20 50 ENDEND If your CSV data isnt joined to the mapserver data, you have to calculate what shapes are in each bucket like this- CLASS EXPRESSION(([NAME] = Shape1) OR ([NAME] = Shape2)) STYLE COLOR 10 20 50 ENDEND --- On Tue, 2/22/11, Daniel Cole dan...@southernsolutionsms.com wrote: From: Daniel Cole dan...@southernsolutionsms.com Subject: [mapserver-users] Heatmap / choropleth from points attributes To: mapserver-users@lists.osgeo.org Date: Tuesday, February 22, 2011, 10:06 PM I am a new mapserver user and have spent countless hours over the last month reading, trying code, etc. before posting here for help. I am trying to generate an image (non-interactive) on a webpage based off of attribute data in a points file. For example, 20 different points equally distributed in a field contain data about the moister level of the soil. I want to make the lowest levels blue and the highest levels yellow, or something like that with some gradients in between. If possible I want it to have interpolated data between them to show the gradual change, but that isn't a must. I also want to wrap it in a polygon that trims the edges. I found some python code that I thought might do the trick , but it seems lots of heat maps are based off of how many points exist in a certain area, and thats now what I am doing. My points contain numbers in the attributes, 5, 25, 92, 71, etc. I feel like I am missing some easy way to do this right in front of me with gdal or something. If someone has any direction or even demo code that would be greatly appreciated.

[mapserver-users] ogr connection trouble
I am trying to get mapserver to draw an OGR layer, was wondering what this means in the OGRINFO readout, I get a series of fields with String (0.0), was wondering what (0.0) means or if its the problem?

RE: [mapserver-users] projecting in degrees
Thanks for the suggestions. I am able to reproject my maps with mapserver. I found out what projection my maps started in by reprojecting in QGIS, it filled in the starting projection. Either it calculated what that projection was, or it was the default. Then, wherever my site modified coordinates in the mapfile, I used cs2cs to convert meters to degrees first. Alaska wraps so I had to change starting longitude to -40. All works good now! --- On Tue, 8/24/10, Fawcett, David (MPCA) david.fawc...@state.mn.us wrote: From: Fawcett, David (MPCA) david.fawc...@state.mn.us Subject: RE: [mapserver-users] projecting in degrees To: Josh Jordan outerspacema...@yahoo.com, mapserver-users@lists.osgeo.org mapserver-users@lists.osgeo.org Date: Tuesday, August 24, 2010, 12:10 PM My understanding of spatial reference systems(SRS) is that the units of the utilized by the SRS are inherently part of the definition. When data is projected to a particular SRS, the units are set by that SRS. It sounds like you are looking for some sort of cylindrical based SRS Maybe Miller Cylindrical (except units are in meters)? http://www.colorado.edu/geography/gcraft/notes/mapproj/gif/millerc.gif http://spatialreference.org/ref/esri/54003/ Maybe straight unprojected lat long? http://www.colorado.edu/geography/gcraft/notes/mapproj/gif/unproj.gif You can possibly handle the conversion of extents on the client side. Your annotations could be handled in ‘degrees’ by defining input projections for your layers and an output projection for your map. Your annotation layer could be in geographic coords and the annotation points would be projected by MapServer. David.

When displayed like this, they look like UTM world projection. However, I need to display it in old style mercator where greenland is really big. I can get mapserver to project as mercator, but it always converts to meters. I would like to project my shapefiles in degrees. Is this possible? I need to because I handle extents and annotation points in degrees. Thanks. ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users
Re: [mapserver-users] maps all look squished
The projection in the mapfile is init=epsg:2023. This is the same projection between /MAP/,/END/ as it is for all the projections between /LAYER/,/END/. When the projection of a layer is not the same as the projection of the map, the layer does not print. It seems redundant to have to write the same projection everywhere.

Re: [mapserver-users] Re: maps all look squished
I have 8 shapefiles, only the states shapefiles returns a projection from ogrinfo. It returns: GEOGCS[GCS_North_American_1983, DATUM[North_American_Datum_1983, SPHEROID[GRS_1980,6378137.0,298.257222101]], PRIMEM[Greenwich,0.0], UNIT[Degree,0.0174532925199433]] It fails if I paste that directly into my mapfile, changing the projection to NAD83 michigan, EPSG 2252, makes no noticeable difference, a screen shot of the map lines up exactly with the squished maps from before. --- On Fri, 8/20/10, Sumit Sharma sumit...@hotmail.com wrote: From: Sumit Sharma sumit...@hotmail.com Subject: [mapserver-users] Re: maps all look squished To: mapserver-users@lists.osgeo.org Date: Friday, August 20, 2010, 10:46 AM it could be projection problem. Have you tried ogrinfo on your dataset? it will give you correct projection and extents of layer. For debugging purposes just try to draw one layer with whatever information you get from ogrinfo. -- View this message in context: http://osgeo-org.1803224.n2.nabble.com/maps-all-look-squished-tp5444218p5444766.html Sent from the Mapserver - User mailing list archive at Nabble.com. ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users
Re: [mapserver-users] maps all look squished
When I change the extents, it will always zoom out so it can fit everything in the extent in the window. So if I change the extent to be only a thin vertical line it makes no difference. Changing the size makes no difference, it was 500 600, I changed it to 100 5000 and 5000 100 and there is no difference. --- On Fri, 8/20/10, Rahkonen Jukka jukka.rahko...@mmmtike.fi wrote: From: Rahkonen Jukka jukka.rahko...@mmmtike.fi Subject: Re: [mapserver-users] maps all look squished To: Josh Jordan outerspacema...@yahoo.com, mapserver-users@lists.osgeo.org Date: Friday, August 20, 2010, 11:22 AM Hi, I have never used any MabObj things, only shp2img, Mapserver CGI and WMS clients. However, I guess that your system is taking the EXTENTS from your mapfile as well as SIZE. If you change the output projection without changing extents you will see nothing because the view window is no more in the same place as the data are. And SIZE parameters can squeese your image, play with them and see. -Jukka- -Alkuperäinen viesti- Lähettäjä: mapserver-users-boun...@lists.osgeo.org puolesta: Josh Jordan Lähetetty: pe 20.8.2010 17:24 Vastaanottaja: mapserver-users@lists.osgeo.org Aihe: Re: [mapserver-users] maps all look squished The projection in the mapfile is init=epsg:2023.
