[mapguide-users] Creating Streets and info

Tue Nov 25 05:07:49 EST 2008

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.
