Evaporative Stress Index (ESI) processed imagery from ECOSTRESS data, captured on October 4, 2021, for Marin County in the San Francisco Bay Area. Darker regions have a higher ESI value, signifying moister conditions, while lighter regions are drier. Vegetative moisture has a significant impact on fire severity and understanding localized moisture conditions can inform the county’s fire suppression efforts. Land outside of Marin County shows NDVI processed imagery derived from Sentinal-2A data.

Canopy cover in the greater Ben Delatour Scout Ranch region from a 2013 NAIP Image with a slope and aspect layer derived from a 10-meter digital elevation model (DEM). This image illustrates how elevation-derived variables are used to inform classification models to map canopy cover. Canopy is displayed as red, and the map illustrates that there are higher concentrations of canopy on northern aspects- illustrating the nature of tree density in our study region. ​

Snow persistence data were processed into snow zones from Terra MODIS 500m resolution data from 2001-2020. 2021 30m resolution rangeland biomass data from the RPMS website. RPMS data (brown and black) are derived from Landsat 5 TM, 7 ETM+, 8 OLI, and 9 OLI-2. The image displays snow persistence zones, with intermittent, transitional, and persistent snow zones in orange, light blue, and dark blue respectively. The image includes parts of the Sawatch and Elk Mountains.

Land cover classification of the Arizona – Mexico border region from April 26, 2022 Landsat 8 OLI imagery. Colors represent land cover types determined by a machine learning clustering algorithm. Classifications help natural resource specialists assess vegetation cover and invasive spread, informing land management practices. The landscape impact of the border is visible as the horizontal break roughly mid-image––Coronado National Memorial and other conserved lands abut the border and experience landscape i

The image was collected by Landsat 9 on January 26 of 2023 showing Skidaway Island and waterways on the Georgia coast. The data shows areas of healthy vegetation and urban areas using a Normalized Difference Vegetation Index (NDVI). The darker orange represents grass and urban areas. Yellow and purple represents forested and densely vegetated areas. The black represents open water.

Soil organic carbon (SOC) is measured here for a depth of 0-5cm from Soil Moisture Active Passive from January 1, 2021 over Peru and Bolivia. SOC is visualized against combined MODIS landcover data for the year 2000 from Aqua and Terra. Shades of lighter pink indicate lower SOC content and darker shades of pink and purple indicate higher SOC content. Conservation International is interested in mapping areas of high SOC content for their conservation efforts.
