Using Remote Sensing to Map Invasive Species
Scientists and researchers are increasingly using remote sensing methods to map and track invasive species.
Mapping and Assessing Landscape Suitability for Bee Migration
Recent studies have shown how GIS and remote-sensing applications could help to assess and map landscape suitability for bees.
Automated Land Cover Maps
Automating the generation of land cover maps from satellite imagery is becoming easier due to learning-based algorithms improving the understanding of signal data.
Measuring Vegetation from Satellite Imagery with NDVI
Normalized difference vegetation index (NDVI) is a remote sensing technique that uses measurement of vegetation signatures to measure vegetation types and growth.
Mapping Soil Moisture in Ethiopia Using Remote Sensing Techniques
Remote sensing can be used to assess soil moisture across a region. Learn more about two methods NASA has used to map out soil moisture in Ethiopia.
Imagery and Its Use in GIS
Most imagery for use in GIS projects consist of satellite images or aerial photographs but it can also include, thermal images, digital elevation models (DEMs), scanned maps and land classification maps. This article examines imagery and how to effectively gather, store, process and interpret it for a variety of different GIS projects.
