The RPCCR tool enables users to dynamically locate areas (within the selected region) in the riparian zone that would benefit most from increased shading produced by planting of trees. The tool operates on a 200 meter stream buffer (100 on each side), and requires the user to specify values for maximum percent canopy cover and minimum solar gain percentile. The user can additionally choose to include minimum elevation (meters) and maximum percent impervious surface values in the analysis.
To use the tool, first select a layer from drop-down list and click Select Feature. The map will change. Zoom to select the polygon (or state) that you want to analyze. Enter the criteria that you want to include and click Make Request. You will see the request(s) in boxes on the right. This can take some time to complete, especially for large areas such as a state. You will see "working" noted next to the request(s). Once the request is complete, all the riparian zones in the selected area will be displayed in yellow, and the portions which correspond to the criteria that was entered will be displayed in black.
The resulting layer is added to the list of available layers with unique name (containing the layer name, the selected polygon id, and each of the input parameters). You can view alternate layers by clicking on the upper right icon of layers and selecting which one you want to view.
