Troubleshooting Map Server

Serving WMS/WFS

To configure Infrastructure Map Server as WMS and/or WFS server

  1. From Infrastructure Map Server - Site Administrator, click Configure WMS/WFS, and update the Server name field with the server name and port of the system on which the Web Server Extensions component is installed. Remove the 8008 port in an IIS Install.
    Note:

    Change the Script name (the path) mapserver/mapagent/mapagent.fcgi to mapserver2012/mapagent/mapagent.fcgi.

  2. In Infrastructure Studio, do the following:
    1. Select the Layer/Feature Source to be advertised for WMS/WFS.
    2. Right-click and select Properties.
    3. Select the Service Properties tab, and set the metadata.
Note:

The WFS Provider is currently for preview only. It may support connections to external WFS sources, but does not support connections to other Map Server WFS sources.

Enabling Infrastructure Map Server - Web Map Service to Use Unsupported SRS codes

Symptom: Using the request=GetMap operation in Autodesk Map Server fails with an InvalidSRS exception, even though the request is well-formed and is using a valid EPSG code.

Background: The OGC WMS standard uses European Petroleum Standards Group designations for spatial reference systems (SRS's.) These take the form of EPSG:nnnn where nnnn is a number. For example, WGS 84 is represented as "EPSG:4326" and California zone 1 in US feet / NAD83 is "EPSG:2225" The coordinate system library used by Autodesk Map Server has only limited support for EPSG codes.

Solution: Autodesk Map Server overcomes this limited support by transforming the EPSG codes into OGC "Well Known Text" or WKT, which the coordinate system library can consume.

To enable Infrastructure Map Server - Web Map Service to use unsupported SRS codes

  1. Find the Well Known Text (WKT) string for the SRS in question. A WKT string looks like this: 
    GEOGCS["WGS 84", 
DATUM["WGS_1984", 
SPHEROID["WGS 84",6378137,298.257223563,AUTHORITY["EPSG","7030"]],        
TOWGS84[0,0,0,0,0,0,0],AUTHORITY["EPSG","6326"]], 
PRIMEM["Greenwich",0,AUTHORITY["EPSG","8901"]], 
UNIT["degree",0.0174532925199433,AUTHORITY["EPSG","9108"]], 
AXIS["Lat",NORTH],AXIS["Long",EAST],AUTHORITY["EPSG","4326"]]
  2. Open the OgcWmsService.config.awd found in the Wms folder of your Server installation using any text editor. Do not use a word processor, as this might corrupt the file.
    Note:

    Back up this file before making any changes.

  3. Find the SRS.WKT.map definition in this file.
  4. Insert the following on the line immediately before the </Define>: 
    <translate from="your:srs">your-wkt-string</translate>

    In the line above, replace your:srs with the SRS that is exhibiting problems, and replace your-wkt-string with the WKT string for your SRS (as discussed in step 1). The results should look similar to the following example (truncated for simplicity): 

    <Define item="SRS.WKT.map">
<translate from="EPSG:21781">PROJCS["CH1903.LV03", ... </translate> 
<translate from="EPSG:9999">PROJCS["Troublesome.SRS", ... </translate> 
</Define>
  5. Save the file.
  6. Stop and restart your web server (IIS or Apache) because this file is cached for performance reasons.
  7. Confirm that a WMS GetMap request using the SRS in question works.

You can put any number of <translate from=""></translate> elements into this definition. However, there is a memory and performance cost with using them, so it is best to define only those you need, and remove those that you do not need.
