Abstract:

This project calculates the Soil-adjusted Vegetation Index (SAVI) from 2013 National Agriculture Imagery Program (NAIP) imagery (1-meter resolution) for the central Arizona region. Because of their large size, data (as GeoTIFF files) for each survey year are provided as multiple individual tiles each comprising a portion of the overall coverage area. An index of the relative position of each tile in the coverage area is provided as a pdf and kml where the tile index contains a portion of the GeoTIFF file name (e.g., the relative position of the data file NAIP_SAVI_CAP2013-0000000000-0000000000.tif to the overall coverage area is identified by the index id 0000000000-0000000000 in the pdf and kml index maps).

Javascript code used to process SAVI values is included with this dataset.

This data set is one in a series of NDVI and SAVI (Soil Adjusted Vegetation Index) data sets for the central Arizona region spanning multiple years (2010-2017). Related data are available through the Environmental Data Initiative - see resouce listing in the methods of this data set for references.

Google Earth Engine was used to create single date or seasonal composites of NAIP imagery.

NDVI and SAVI were computed from the NAIP sensor with a 1-m spatial resolution.

The NAIP imagery is taken from an airplane, so while it has a high spatial resolution, it may not be reliable for time-series analysis. NAIP products are best for use in an analysis that focuses on a single year or for maps/visualizations.

NDVI is computed using the near-infrared (NIR) and red (RED) bands because red visible light (0.63-0.69 μm) is absorbed by a plant’s chlorophyll while near-infrared light (0.77-0.90 μm) is scattered by the leaf’s mesophyll structure: NDVI = (NIR - RED)/(NIR + RED).

SAVI is computed using the same bands as NDVI along with a constant that corrects for soil brightness (Huete 1988). It is calculated: SAVI = ((1 + L)(NIR – RED))/(NIR + RED + L) where L = 0.5. SAVI is a complementary vegetation indice to NDVI in desert regions, such as the Phoenix metropolitan area, because SAVI minimizes the influence of soil brightness.

Description: SAVI for the central Arizona region derived from 2013 NAIP imagery. NAIP SAVI data are presented as a series of tiles each representing a portion of the overall central Arizona coverage area. The relative position of this tile (0000069888-0000139776) to the entire coverage area is detailed in the files NAIP_GRID.kml, NAIP_GRID.pdf, and NAIP_GRID.png included with this data set.
