Enhanced Layer Functionality
This chapter describes the new enhanced layer
functionality for layers that use spatial data provider
(SDP) and OLE database data sources. You can use these
new features to apply geometry functions to map
features, apply filters to spatial queries, define custom
spatial queries, and apply pre- and post-query SQL
statements to the spatial queries.
To use the new enhanced layer features, you need to be an
advanced Autodesk MapGuide user with a solid
understanding of Oracle Structured Query Language
(SQL).
