Explore our project types
Our volunteers contribute to several different project types.
Find Features
Swipe through satellite images to identify & select those that contain the requested features such as buildings, roadways, waterways and more.
Compare Dates
Review before and after satellite images to detect changes in the environment that help inform damage assessment, climate change, or inaccurate data.
Validate Footprints
Assess building footprints for accuracy where buildings have been previously traced by remote mappers or through AI to identify where remapping is needed.
Check Completeness
Check an overlay layer (e.g. mapped buildings) against aerial imagery to identify areas that are not completely mapped.
Assess Image
Review photographs to identify the presence of a feature or validate detections as part of mapping workflows and to improve machine learning tools.
View Streets
Explore ground-level photos to find relevant features and capture more detailed information on communities.
