## What is Open?

Open-red is the citizen science app for measuring and mapping the environment.

Connect your measurement device over Bluetooth (RadiaCode for gamma radiation, Opple LightMaster for light pollution) and record geolocated tracks as you move. View your measurements on the map, check the spectrum or the color diagram in real time, and upload your routes to contribute to an open, collaborative map.

Key features:
• Bluetooth connection with RadiaCode and Opple LightMaster 3
• Track recording with high-precision GPS
• Radiation: dose (µSv/h), CPM and gamma spectrum with isotope lines
• Light: lux, color temperature (CCT) and CIE chromaticity diagram
• Map with your measurements and reference layers
• Sync and share your tracks with the community

Open-red is a citizen science project by Ibercivis.
