| - | We are pleased to announce a new set of static Map Suite APIs relating to topology, along with an application to test topology rules. Topology is a critical function of a GIS application and we now have a great implementation of this feature. We have worked hard to ensure that we have included the most important cases along with an easy-to-use API. Below are a list of all of the cases we cover. | + | Topology refers to the relationship between lines, points, and polygons. For more information about the concept of topology please visit [[https://en.wikipedia.org/wiki/Geospatial_topology|this Wikipedia article]]. Map Suite offers a set of static Map Suite APIs relating to topology, along with an application to validate topology rules. Topology can be very useful in GIS as it allows users to clean up data or to modify geometries to comply with different rules and restrictions. Below is a list of all of the topology cases this sample covers: |
