[mapserver-users] Valid extents for shape file, World Wind WMS Client

[Lime, Steve D (MNIT)]

Hi Jonathan: Looking at the Houston zip file one sees the .prj file references Google Mercator. So that's what you need to define for your layer. Here's the new mapfile... You don't need to mention anything about geographic coordinates here other than the fact you support requests in that srs.

The second message means you must have set the environment variable MS_DEFAULT_MAPFILE_PATTERN in your web server configuration and that the mapfile being passed as part of the incoming request doesn't pass that validation check. The problem may be in your wms_onlineresource where you have an extra trailing ? in the URL.

Subject: [mapserver-users] Valid extents for shape file, World Wind WMS Client

I am looking for help getting the Extents set correctly in my map file and getting my World Wind WMS client working correctly with MapServer.

I have been using NASA's World Wind Java SDK for a while now and finally decided to run my own map server to provide access to shape files.

I am brand new to map servers. I started with MapServer. It is up and running on a CentOS virtual machine. 

I downloaded a shape file for Houston TX from OpenStreetMap as a starting point for my data set.
http://metro.teczno.com/#houston

I followed the examples as best I could to setup my "map" file for use with MapServer. I used ogrinfo to get the extents of the Houston shape file:
"ogrinfo -al -so /path-to-shape-file/houston.shp". It returned:
Extent: (-10720217.000000, 3306038.000000) - (-10419354.000000,
3606902.000000)

This is clearly not decimal degrees. This must be meters right?

I put that Extent in my map file. When I point WorldWind (via the WMSLayerManager example) to my WMS URL, it correctly gets the layer names however when I select one to add to the display, it spits out an error,
"SEVERE: Angle out of range -1.04194E7°". Clearly it is trying to use the Extent as a decimal degree.

*Any thoughts on how I fix this? I will include my map file and get capabilities response at the end of this email.*

Now if I change my map file to use the extents, "-180 -90 180 90" (which is clearly not correct but a good test), World Wind no longer complains about a bad angle. Instead it provides error messages that must be from MapServer:

msLoadMap(): Regular expression error. MS_DEFAULT_MAPFILE_PATTERN validation failed.
msEvalRegex(): Regular expression error. String failed expression test.

So my question is two fold:

1) How do I get the decimal degree extents that World Wind appears to be expecting?
2) What does that msLoadMap error message mean and how do I correct it? 

Thanks.
