Information about the number of DAP returns per pixel for the 2017 Statewide DAP data.

This raster can be used to help identify why specific pixels are “No Data” in the final model prediction rasters.

Gridmetrics produces a count of the number of returns in each pixel. By default, gridmetrics will not calculate metrics for a pixel if it has less than four returns. Height thresholds are defined in gridmetrics for cover calculations, and to exclude returns below a specific height from being used for tree height calculations. For this project, both thresholds were set to six feet. If a cell only has returns below these thresholds, cover and height metrics will not be calculated by gridmetrics.
