Scientific manager: Dr.sc.comp. Ints Mednieks (ints.mednieks@edi.lv).
Project objective: to develop a novel technology for the cost-effective estimation of forest stock volume based on high-resolution satellite remote sensing data.
The project is focused on the development of the prototype technology for estimation of forest stock volume from high-resolution satellite data, including methods for identification of tree species, estimation of tree height, estimation of forest density and estimation of forest stock volume from information about tree species, tree height and forest density.
The project is implemented by the Institute of Electronics and Computer Science in cooperation with company SIA “Baltic Satellite Service”.
Duration: 36 mēneši, from March 1, 2019 to February 28, 2022.
Planned cost: 498 026 EUR
