Applications of Handheld Off-The-Shelf Multispectral Spectrometers for Improving Water and Soil Quality Assessments for Satellite Earth Observation
The study evaluates the performance of NASA’s Science and Technology Education for Land/Life Assessment (STELLA) 1.1 spectrometers as affordable tools for collecting water and soil quality data to support satellite Earth Observation (EO) calibration. Spectral reflectance data collected by STELLA devices across freshwater and agricultural sites are compared against a HySpex VS-620 hyperspectral imager and satellite imagery from Sentinel-2 and Landsat. Findings aim to demonstrate that low-cost, handheld spectrometers can provide reliable ground-truth data, expanding environmental monitoring access to regions with limited infrastructure. Future work should explore establishing measurement protocols using STELLA and integrating their data into current EO calibration methods.
