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.
