Summary

Shrublands have seen large changes over time due to factors such as fire and drought. As the climate continues to change, vegetation monitoring at the county scale is essential to identify large-scale changes and to develop sampling designs for field-based vegetation studies. This dataset contains two raster files that each depict the height of vegetation. The first layer is restricted to actively growing vegetation and the second is restricted to dormant/dead vegetation. Both layers cover open space areas in San Diego County, California. Height calculations were derived from Lidar data collected in 2014 and 2015 for the western two-thirds of San Diego County. Lidar point clouds were pre-classified into ground and non-ground. Rasters [...]

Purpose

This dataset was created to be used with field visits to monitor vegetation structure and health in San Diego County. The Normalized Difference Vegetation Index (NDVI) and height are intended to help describe the vegetation form and health. This will be an ongoing analysis to incorporate field data and future years of remote sensing information to understand how these factors change over time.
