FDO Data Provider for MXT 2008 v7 to access ArcSDE, MySQL and other sources
This download contains an extensible data provider implementation for MapXtreme that connects the FDO data providers into the MapXtreme SQL engine. FDO is an open source data access API for accessing multiple data formats. It has a provider based model similar to MapXtreme's data provider architecture. This data provider enables FDO data providers to be used in a MapXtreme application.
To learn more about FDO visit the FDO site located at http://fdo.osgeo.org/. There are FDO providers for many different formats including ESRI ArcSDE, MySQL, SDF, WFS, GDAL, and OGR. There are several other FDO providers available as well; however, those formats are already accessible using built in technologies in MapXtreme including Oracle, SQL Server (including SQL Server 2008 Spatial new in v7.0), ODBC, and WMS. Additionally, there is an extensible data provider for directly accessing PostGIS that is also available on the Code Exchange. The FDO OGR provider also provides access to a variety of spatial vector formats which can be found at http://www.gdal.org/ogr/ogr_formats.html. The formats include ESRI Personal GeoDatabase, GeoRSS, GRASS, Microstation DGN, KML, SDTS, S-57, FME Objects, Atlas BNA, Arc/Info .E00 Coverage, Arc/Info Binary Coverage, and more.
The MapXtreme data provider for FDO is currently read-only. The extensible data provider capability, the WorkspaceManager extensibility, and the SessionEventHandler capability are all new extensibility mechanisms introduced to MapXtreme 2008 version 7.0.
