Hi Mark,
Can you provide more context as to why you need to obtain the river length and elevation data in relation to your chosen project opportunity to work on? We have recommended readings in Design Area 2 – Water Supply to help you understand the river systems in Mondulkiri Province and Kaev Seima district, where Pu Ngaol village is part of. Specifically, check Map 7 in the Technical Report on Mondul Kiri Provincial Spatial Plan (2020 – 2040).
We’ve just updated our Resources page with a downloadable aerial image of Pu Ngaol village surrounds (high resolution). We placed some pins there to view the prominent landmarks featured in our Interactives: 360° Site Walkthroughs.
Regards,
Jean
