===== Topology Validation =====

This video will give you a demonstration of Map Suite's topology validation functionality (available in version 6.0.113.0 and higher), as well as the [[Map Suite Desktop Edition Miscellaneous Samples#Topology_Validation|Topology Validator sample application]]. The Topology Validator makes it simple to visualize and test topology rules. You simply select the case you want to test, use our drawing tools to create the shapes necessary, and then hit the play button to run the test. The error cases are highlighted on the screen and saved to the test, and their Well-Known Text (WKT) is copied to your clipboard. At any time, you can view or edit the WKT which makes up the case. We save our test cases as XML files that contain not only the test case features but also the errors. This makes it a snap for you to share your cases with us or other colleagues.

We are pleased to announce a new set of static Map Suite APIs relating to topology validation, along with an application to visualize and test topology rules. Topology validation 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.

The sample application, at the link below, makes it easy to visualize and test topology rules. You simply select the case you want to test, use our drawing tools to create the shapes necessary, and then hit the play button to run the test. The error cases are highlighted on the screen and saved to the test, and their Well-Known Text (WKT) is copied to your clipboard. At any time, you can view or edit the WKT which makes up the case. We save our test cases as XML files that contain not only the test case features but also the errors. This makes it a snap for you to share your cases with us or other colleagues.
