Easily Extract Rooftops and Buildings FeatureAssist for ArcGIS is an optional add-on to Stereo Analyst for ArcGIS that lets you collect complex building roofs in the Esri multipatch format, which is an industry-standard format used to define the outer shape of 3D objects. You can also generate 3D models with the roof outlines using quick and easy tools that let you create walls that extend from the rooftops to the ground.
Convenient Templates for Faster Roof Collection
Many roofs have a common shape. FeatureAssist for ArcGIS includes a wide selection of templates to help you collect those roofs, as well as tools that allow you to fine-tune the match between the template and the exact roof shape. It also provides freeform manual tools so you can collect unusual roof shapes.
