Geodatabase topologies were introduced in ArcGIS Pro with\u00a0yesterday\u2019s 1.3 release. In general terms, they model spatial relationships and allow you to perform actions based on those relationships.<\/p>\n

A common use of a geodatabase topology is to check the quality of feature edits. The topology determines whether features follow predefined topological rules–that is, permitted spatial relationships. If a rule is broken, an error is recorded and flagged. For example, in this post you will check whether each road segment (line feature) has an intersection (point feature) on each of its two endpoints; the topology will flag endpoints that aren’t covered by a point feature. Geodatabase topologies go a step further–they also help you fix these errors. \u00a0(The help topic on geodatabase topologies<\/a> describes other ways topologies can be useful.)<\/p>\n

Set up ArcGIS Pro 1.3<\/h1>\n
    \n
  1. This post demonstrates new functionality available in 1.3, so you will need to have ArcGIS Pro 1.3 installed on your machine. The\u00a0post announcing the 1.3 release<\/a>\u00a0provides guidance on that. See the Get ArcGIS Pro 1.3 section. Although you need the Standard or Advanced license level to fully complete geodatabase topology workflows, you can see much of the topology interface–and become familiar with it–by using the Basic license.<\/li>\n
  2. Download the project package<\/a> that includes data for this hands-on experience.<\/li>\n
  3. In the download, double-click GeodatabaseTopology.ppkx to open the project.<\/li>\n<\/ol>\n

    Create the geodatabase topology<\/h1>\n

    ArcGIS Pro lets you\u00a0validate topologies and address errors, but it isn\u2019t currently capable of creating topologies\u2014that capability will come in a release sometime after 1.3. For now, you create geodatabase topologies in ArcMap or ArcCatalog<\/a>.<\/p>\n

    The GeodatabaseTopology project you downloaded contains a map and a rudimentary dataset of roads that includes three items: a line feature class for representing roads, a point feature class for representing intersections, and a topology for checking whether road and intersection features follow two topological rules:<\/p>\n
