As discussed on our Services page, we are now offering MapGuide Open Source services. MapGuide Open Source was contributed to the GIS community and is now owned and governed by the foundation. The software no longer has any ownership affiliation with Autodesk. Also, this software is of a completely different architecture than the "old" MapGuide and is the web map server software of the future. We have been using the software since the alpha releases and are very familiar with and have extensively programmed using the new API. In our demo site, we are using the HTML viewer which uses AJAX technology and requires no plugin or download.

This site demonstrates utilizing the MapGuide Open and FDO API’s which allows us to build Google Earth KML and KMZ files on the fly based on calls from the Google Earth client. A master KMZ is created that establishes the Google Earth network link layers with each layer pointing to custom pages on our server. As the user navigates Google Earth, a call is made to each page and the spatial information for that particular bounding box area is streamed back live from MapGuide Open Source. In addition to the data from MapGuide Open Source, we wrote a custom application to deliver the property structure photos as on-the-fly thumbnails. These are included in the information windows when you click on a parcel. Additionally, you can access the live County tax assessor property report from the info window.

This site demonstrates the integration of MapGuide Open Source data and Google Maps. Using the MapGuide and FDO API's, we wrote a custom application to stream parcel polygon information as a Web Map Services (WMS) layer. The MapGuide Open Source API was used to dynamically stream Google Map marker points whenever the map view changes. Custom code was written to take the bounding box of the current Google Map view, use that as the basis for a spatial overlay query against the parcel datasource, and then extract the parcel centroids latitude and longitude. The complete XML marker file is then constructed from this and any related attribute information. This allows us to display as much information about that feature as possible when you click on it. This includes property structure photos derived from the same custom application utilized in all of our sites.
