The GLOBE Observer app enables you to make observations of your environment. GLOBE Observer is the app of the Global Learning and Observations to Benefit the Environment (GLOBE) Program. The GLOBE Program is an international science and education program that provides students and people of all ages worldwide with the opportunity to participate in data collection and the scientific process, and contribute meaningfully to our understanding of the Earth system and global environment. By using the GLOBE Observer app, you contribute scientific data to your community, students and scientists worldwide, including researchers at NASA, NOAA, and other science research institutions. GLOBE Observer allows all users to contribute observations of clouds, mosquito habitats, land cover, and trees. Trained and certified users can also use the app to submit additional environmental measurements from all GLOBE protocols. GLOBE Clouds allows observers to make regular observations of Earth’s cloud cover and compare them to satellite observations. With GLOBE Mosquito Habitat Mapper, users locate mosquito habitats, observe and identify mosquito larvae, and reduce the potential threat of mosquito borne disease. GLOBE Land Cover is designed to allow users to document what is on the land (trees, grass, buildings, etc.). GLOBE Trees asks users to estimate a tree’s height by taking pictures of trees with their device and answering a few questions. Additional capabilities may be added.

CoastSnap is a global citizen science project to capture our changing coastlines. No matter where you are in the world, if you have a smartphone and an interest in the coast, we welcome you to participate! CoastSnap relies on repeat photos at the same location to track how the coast is changing over time due to processes such as storms, rising sea levels, human activities, and other factors. Using a specialized technique known as photogrammetry, CoastSnap turns your photos into valuable coastal data that is used by coastal scientists to understand and forecast how coastlines might change in the coming decades. Photogrammetry enables the position of the coastline to be pinpointed from your snaps with an accuracy similar to that of professional coastal survey teams. All we ask is that you take the photos at the same location (by using one of our official CoastSnap camera cradles or a do-it-yourself adaptation) and record the precise photo time in the App. The more photos we have of a particular site, the better our understanding becomes of how that coastline is changing over time.The CoastSnap App is running on the SPOTTERON Citizen Science platform.
