Re: [mapserver-users] Split Polygon using Clint or server side code not with PostGIS
Hi, Are you trying to split a polygon using another geo object like a line? Or do you just want to divide the polygon in smaller pieces? You may want to look at triangulation for that.

Re: [mapserver-users] Split Polygon using Clint or server side code not with PostGIS
Hmm. No guarantees, but perhaps the geoapi.net or nettopolgysuite have this functionality. Alternatively, what you could do, although it still involves a spatial database, is use the C# Sql Spatial libraries. You could install a microsoft sql server 2008 (spatial) database, reference the spatial libraries and perform the split of the polygon with those spatial functions, using C#. But as you stated, this is probably not the solution you are looking for. Maybe someone else is aware of another third party library that does this :).

[mapserver-users] MapServer and MapScript in separate hosts
Hello: Maybe its a silly question but Id like to know if I can use MapScript in a web server with PHP being MapServer installed in a different host. All the examples Ive seen seem to run in the same server and I cant find a way to set up an URL for the MapServer location. Thank you. ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users
Re: [mapserver-users] MapServer and MapScript in separate hosts
Hi, If you compile mapserver from source, you can use ./configure --prefix=/path/to/executable to install it in the folder you want. You do need to make sure that LD can find the shared libraries. This should then be set in apache config so that the right environment paths are loaded. As for the external URL thing. Just configure a CGI script at a given URL (as configured in your webserver) and then point to the location of your mapserv executable. Perhaps this is what you are looking for: http://mapserver.org/cgi/wrapper.html 2010/9/7 Román González rgonza...@normagricola.com Hello: Maybe it’s a silly question but I’d like to know if I can use MapScript in a web server with PHP being MapServer installed in a different host.

Re: [mapserver-users] Split Polygon using Clint or server side code not with PostGIS
Ven, First, I took a quick look at the php mapscript documentation (my preferred mapscript) and didn't see anything specific about splitting. Solving a more simplified problem might be a start. Start by getting the bounding box of the polygon ($shp-bounds). Get the two left side coordinates: $p1=(MinX, MaxY), $p2=(MinX, MinY) Build a new polygon using these two points and the endpoints of your line. -- Assumption that your line is not horizontal or intersects the left edge of your bbox. Use the shapeObj::intersection to get the half of your target polygon within the left half of the BBOX. You can repeat this for the right half of the BBOX, or maybe use shapeObj::difference. My first thoughts. You could, alternatively, loop through all of $shp-lines(1..$shp-numlines) and checking for intersection with your split line. A little bookkeeping would allow you to build your two split polygons from this. I think option 1 might be easier.

RE: [mapserver-users] formatting query and identify results
You can embed javascript in a template result but it's up to the client to execute it (MapServer won't).

I could add a new column to the data to create a new mask so that the application will work.

Since the data source has the wrong mask, any data updates from my client will not include the correct mask.

Thanks Mark Volz GIS Specialist Not sure if this is relevant, but I have kinda the same problem, some of my data has parcel masking and some does not. I usually add a new column (I'm use PostGIS, not shapefiles, but I assume you could still do it) and set it with the masking I'd like to display. So I have a pin field and a display_pin field, and can query/join on one and display the other. I know you said you would not update the data, but if I carefully read that as not modify the existing pin, then adding a new column would not count as modify the existing pin. -Andy ___ 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
[mapserver-users] Dynamically draw different sized ellipses on map
Was hoping on some guidance as to the best way to attack this... My app uses the cgi interface. I have been succesful at drawing lines, squares and small circles on the fly by sending mods to the .map file via the URL. I have been doing this by dynamically adding points to various POINT layers with the afforementioned symbols. Up to this point, the squares and circles have been uniform in size and aspect. Now I find myself needing to add multiple ellipses of varying sizes at different locations on the map. Technically they would be circles of area, but the aspect will change as the location approaches the poles. (almost a true circle at the equator and verly long ellipse toward the poles due to map projection). Ideally the ellipses will be filled with either a hatch pattern or a transparent solid color. Any suggestions as to the best way to accomplish this?
