Hi,
My suggestion would be somewhat similar, but in stead of keeping an
column updated with the WKT or WKB, I would suggest that you use a view where
the SpatialWare ST_Spatial is converted to WKT og WKB

Kelly Sent: Friday, March 17, 2006 7:10 AM To: [email protected] Cc: Ian Tidy Subject: RE: [MI-L] MapServer and SpatialWare Ian I must state first that
I have no experience with MapServer, but I do use SpatialWare with another non
MapInfo IMS, so I feel the issues may well be similar. I had a quick read
through the MapServer online documents, and it seems that MapServer does not
directly support the SpatilWare format. If you are using Oracle, MapServer
does support the Oracle format. I am coming from the
SQLserver implementation of SpatialWare. I noticed that MapServer does
support ODBC and can access geometry through this, as long as the geometry is in
OGC well known binary (WKB) or well known text (WKT) format. The IMS I use
is in exactly the same position, so I have programmed triggers on my tables so
that when items are added/altered in the Spatialware tables, then a column
containing WKB is also altered. Spatialware has the ability to convert its
own format to WKB using one of its spatial functions. One thing to note
that if you have a lot of users and decent size tables, ODBC will be pretty
slow. There may be other
methods using MapServer, I only had a very, very quick
look. Cheers James

[mailto:[EMAIL PROTECTED] On Behalf Of Ian Tidy Hi, Has
anyone got MapServer working with SpatialWare? I am in the process of
testing MapServer and would like to access our live SpatialWare
tables. Any
help would be appreciated. Cheers Ian
