The main table has GPS positions as a float as well as a SQL Server 2008
Geography column. I have used the lat/lon columns as point data on the map and
themed very nicely. However, I need extra information from other other tables
that will be used for more theming, extra info, highlighting roads that have
speed violatations, etc.<o:p></o:p></span></p>

using the ODBC provider to connect to the database. I am not using the spatial
provider for this layer. I use shape files uploaded to the repository to
which the GPS points in my lat/lon columns line up along nicely. One
thought occurs to me now, should I update the FDO? I am using the
out-of-the-box version. I’ll check if there is an updated version
and try again.<o:p></o:p></span></p>
