The USGS Western Geographic Science Center has been partnering with collaborators from the San Carlos Apache Tribe (SCAT) and Bureau of Indian Affairs (BIA) to address natural resource questions since 2004. We work with SCAT Departments of Forestry, Range Management and Environmental Protection.

Low versus high radiometric resolution. Low resolution is low data storage, meaning only a few shades can be seen (as in the left image), high resolution is more data storage and means more shades can be recorded (right image).

Two glasses of water, the one on the left has dissolved organics and particulate matter in it making it brown and cloudy. The glass on the right is clear and clean and colorless. This illustrates the main concept of aquatic remote sensing: water color changes based on what’s in it and we can link those color differences to differences in composition.

Example spectra of water, water with algae, and water with sediment. The x-axis is wavelengths of light. For remote sensing of water, we are only interested in the visible range (400 nm – 700 nm) and a little bit of the ultra violet and infrared. The y-axis is the amount of light in each wavelength.

Examples of low- and high-resolution imagery. Higher resolution imagery allows more detailed spatial patterns to be viewed in the imagery.

Examples of high and low temporal resolution. A high-resolution sensor might image an area every day or two, whereas a low-resolution sensor might only image an area on the order of weeks.

This teacup has a moderate amount of dissolved organic material, which absorbs blue light but reflects some red and orange light. The coffee cup has a high amount of dissolved organic matter and appears almost black because of how much light it is absorbing.

Examples of spectral resolution. High resolution sensors image many bands (i.e., colors) and lower resolution sensors image fewer bands. Higher spectral resolution lets us view more of the spectrum, but has cost, data storage, and band sensitivity trade-offs.

The LP DAAC is pleased to announce the availability of five new Landsat-Derived Global Rainfed and Irrigated-Cropland Product at 30 meters (LGRIP30) Version 2 data products for the nominal year 2020. New Level 1 and Level 2 irrigation and rainfed data products subdivide their respective cropland types to provide greater detail in cropland spatial distribution.
