Commissioners probe plan to use cell‑phone GPS data (Zartico) in Lake George study

Commissioners questioned the study team's plan to test Zartico mobile‑phone/GPS data for mapping boat and visitor movement, asking how multiple devices on a single boat would be handled and whether the data can be reliably tied to the study's grid; staff said Zartico produces aggregated 'blobs' and the team will test viability next week.
