“The Canadian Hydrospatial Network (CHN) is a map-based dataset that includes Canada's lakes, rivers, watersheds and other water features and their connections to each other.
It's applications include:
🗺️ serving as a foundation for advanced hydrologic and hydraulic modelling, including for flooding and drought
🗺️ supporting water and watershed management
🗺️ providing essential base data for cartography…”
You can now explore six new regions …”

[A very comprehensive hydrographic and shallow geophysical study and mapping effort of Lake Titicaca…]
“In October 2024, officers from the Category “A” Specialization Programme in Hydrography for Naval Officers of the Peruvian Navy conducted their complex multidisciplinary field project at Lake Titicaca at Puno in Peru, which is the highest navigable lake in the world (3,800 metres above sea level). The purpose of this survey was to address issues in the lacustrine environment due to hydrological processes that have occurred in recent years in this water body.…”
