Fuels Data is designed for wildland management practitioners tasked with collecting surface fuels measurements in the field It automatically performs calculations and table lookups. Photos and data are linked together, which eliminates the need to diligently sequence reference photos to align with data. These features reduce the risk of mistakes in transcribing and reviewing collected data in the field. The collected data may also be uploaded to the Allen Institute for Artificial Intelligence to build and train fuel load estimation models.
CheatMaps
Easily document cheatgrass sightings in the field using a computer vision model for identification. Submit photos and descriptions to create observations, with AR tools for richer data capture. Explore and export data to understand its spread.
- On-device computer vision for identification
- Submit photo and description observations
- AR tools for richer field data
- Explore observations on a map
- Export dataset for analysis

CheatMaps is an app designed to track the spread of cheatgrass within the Gunnison Basin, aiming to address the ecological challenges posed by its proliferation. Version 1.1 was developed as part of the 2024 Western Colorado University & University of Colorado Boulder Partnership Computer Science Capstone project. Update 2.0 is developed by the University of Colorado Computer Science capstone team. Both iterations are in collaboration with the Gunnison Sagebrush Alliance. Whether you are hiking, exploring, or spending time in the great outdoors, CheatMaps makes it easy to document cheatgrass sightings in the field. Users can first identify cheatgrass using an on-device state-of-the-art computer vision model, then submit that photo along with a description to create an observation. For more detailed observations, the app also includes AR tools that help users capture richer field data. Users can explore observations submitted by others on the map and export the dataset to better understand the spread of cheatgrass throughout the Gunnison Basin and beyond. By connecting everyday outdoor activity with ecological monitoring, CheatMaps is a valuable tool for researchers, land managers, and anyone passionate about preserving the ecological balance of the Gunnison Basin.
