Mapping Polygonal Change Over Time
A common geospatial problem is having out of date polygonal GIS layers but more recent imagery which represents the more current state of the features. This movie shows an example of using IMAGINE Objective to update a shapefile of building footprints using recent aerial photography.

Explanation of How Polygon Features Might be Extracted
This movie goes into greater detail on the use of IMAGINE Objective to extract residential building footprints from a high resolution color air photo into a vector GIS shapefile format. Explanation is given on the steps that are applied within the Feature Model to analyze, extract and clean up the building footprints.

Extracting Polygon Features
This movie depicts the use of IMAGINE Objective to extract residential building footprints from a high resolution color air photo into a vector GIS shapefile format. The extracted features are automatically formatted to have straight walls and right-angled corners rather than being approximated “blobs”

Extracting Linear Features
Using IMAGINE Objective to quickly and simply map the location of suburban roads from a high resolution color air photo into a vector GIS shapefile format. The IMAGINE Objective processing includes the ability to jump gaps and form junctions to minimize any manual post-processing that might otherwise be required.

Start to Finish Creation of a Feature Model
This movie shows how IMAGINE Objective is used from scratch to build, validate and execute a Feature Model capable of extracting features of interest from imagery. In this example the problem being solved is the identification and mapping of as-built sewer man-hole covers for a Utilities company. Problem scenario and data is courtesy of Imagem B.V. in the Netherlands.
