#Canada relies heavily on foreign GNSS systems (primarily U.S. GPS), licenses GIS software from foreign vendors, and outsources significant portions of its spatial data infrastructure. In many cases, critical national geospatial data — used for defense […] [Original post on mapstodon.space]

What Canada lacks:
- A sovereign GNSS or a robust Independent fallback system
- EO constellations tailored to security needs
- Investment in Canadian- developed GIS platforms
- Domestic hosting or control of government geospatial data

Recent disturbances detected along western border of park.
In Indio Maíz, the 1,323 hectares of disturbance alerts measured in April 2024 were roughly equal to total disturbance alerts within the reserve for all of 2023.

Recent disturbances detected densely throughout southern half of the park.
Total disturbance alerts in Bosawás in the second quarter of 2024 were nearly 68% higher than they were during the same period in 2023.
