Is there any way for drawing a map starting from objects coordinates data on a
DB?
I'm thinking about creating a layer reading from a MySql db... what do you
think about?

My coordinate system is relative and local, it is metric and its origin is a
(0,0) point on the planimetry.
If the map is generated by these metric data points on the DB, how would you
suggest to handle a sequence of GPS vehicles positions, which must be displayed
on the map ?
Have I transform GPS positions to local system coordinates (or the map
coordinates to GPS)?? Or is there any other way?
For drawing the map I have 2 ways:
1) using the DWG planimetry file (which now is geo-referenced)
2) reading objects data on a DB table, on which I have local coordinates of
objects centers, and drawing the map according to these data
The method (1) is what I'm using now, but it has some limitations:
- it's not possible to create the map programmatically, the map is created on
Autocad, which DWG file is imported into MapGuide. Therefore every map changes
must be done manually on Autocad
- it's not simple to attach additional fields values to Autocad objects
Which way would you suggest?

You can use X/Y data in any coordinate system, not just Lon/Lat in an ODBC
Connection.

If you select the correct projection for both the data sources, and the map,
MapGuide should fix it correctly for you.
If you have X/Y data (lat/lon) in MySql, you can use the ODBC provider to
map the data into points.

Thank you Kenneth, now it works :-)
Another question:
I've got objects coordinates and data on a MySql DB. Is it possible to use
it to draw a layer with these objects?
Object coordinates are local relative coordinates. Vehicles positions on my
DB are lat/lon GPS coordinates. Have you got any suggestions about dealing with
these different coordinates?
Thank you very much again
Cheers

I see the problem now.
You must include ALL the files, not just the SHP file.
After that you must select the shp file to be the "main" item (the star
button in Maestro).
I can send you a package where I have done this if you like.
The problem is that Maestro only displays "*.shp" in the file type, and
you must select "All files" before you can add those other files.
Feel free to add a feature request for the problem:

I tried using the exported SHP file with MapGuide Maestro. Using the
ajaxviewer example SDF files I see many attributes, but using my exported SHP
files I see only the FeatId field. If from Autocad Map I export data to SDF
format I've got the same problem...
If from Autocad Map I connect to the SHP data file I can see its
attributes values on the data table. How come MapGuide Maestro doesn't display
them?
The SHP file is attached with this message,
please help me

I am no expert on SHP data, but with most data, the attributes are
included.
If you use SHP data in MapGuide the attributes should be IN the SHP (or
is it dbx, etc) file.
>From then on you can see the columns everywhere, and use the
attributes as label or other stuff.
If you select the columns to view on the layer, they will show up, just
like the parcel data.
If you use Arc, the attributes are also attached to the topology, so
the export should be able to extract that as well.

Thank you for your help.I've found how to create object data. The problem is
that I've got manyobjects (about 10.000), then I need an automatic method to
attach data toobjects. Some people told me to follow these steps:1) create a
topology2) export a SHP file with topology data3) use topology ID to make a
JOIN between topology data and data I need toattach4) import in Autocad Map the
SHP file5) label objects, using the Style tool6) create a link template7)
generate links to "Enclosed Text" On Autocad Map guide I saw that it is
possible to automatically link objectsto data on a DB table. But it requires
labels. Using labels created as Isaid here doesn't work... Other people told me
to attach objects data using a GIS software, but didnot say which software and
how :-( I hope anybody here can help me, because it's taking a really long time
forthis purpose... I need to develop something similar to the ajaxviewer
example, on which youcan view info about Parcels. Hoping in your
