Use the model

You can use this model in the Classify Pixels Using Deep Learning tool available in the Image Analyst toolbox for inference or the Extract Features Using AI Models tool available in the GeoAI toolbox in ArcGIS Pro for inference and postprocessing of the inferred results. Follow the steps below to use the model to extract parcels from high resolution imagery.

Supported imagery

High resolution imagery with the following characteristics is supported:

• Spatial resolution—High resolution (30–50 centimeters)
• Bands—Three bands (for example, red, green, and blue)

Extract roads

To extract roads from the imagery, complete the following steps:

1. Download the Road Extraction—North America model and add the imagery layer in ArcGIS Pro.
2. Zoom to an area of interest.

   

3. Click Tools on the Analysis tab.

   

4. Click the Toolboxes tab in the Geoprocessing pane, expand GeoAI Tools, and select the Extract Features Using AI Models tool under Imagery AI.

   

5. On the Parameters tab, set the parameters as follows:
   1. For Input Raster, choose the input raster on which processing will be performed.
   2. Optionally, for Area of Interest, set the geographical extent that will be used to extract features.

      Only features within the area of interest will be extracted.

   3. For Mode, select Infer and Postprocess mode.
   4. Optionally, for Output Location, select the file geodatabase where the outputs will be stored.
   5. For Output Prefix, set a prefix that will be added to the name of outputs and name of group layer.
   6. Set the Pretrained Models drop-down list to the ROAD EXTRACTION - NORTH AMERICA pretrained model.
   7. Set Line Regularization Options.

      Line postprocessing is the default postprocessing option for this model. The options are as follows:

      • • Buffer Distance—The distance to create a buffer around input features. Change the value if needed. The default value is 15 meters.
        • Extend Length—The maximum distance a road line segment can be extended to an intersecting feature. Change the value if needed. The default value is 25 meters.
        • Smoothing Tolerance—The value for smoothing the road line segments. Change the value if needed. The default value is 30 meters.
        • Dangle Length—Road line segments that are shorter than this length and do not touch another line at both endpoints (dangles) will be trimmed. Change the value if needed. The default value is 5 meters.

        

6. On the Environments tab, for Processor Type, set GPU ID to the GPU to be used.

   

7. Click Run.

   The output group layer with postprocessed roads is added to the map.
