Providing Reference Forest Biomass Data For Eo Imagery : A Comparison Of Four In-Situ Relascope Measuring Devices In Asturias, Spain
2019 IEEE INTERNATIONAL GEOSCIENCE AND REMOTE SENSING SYMPOSIUM (IGARSS 2019)(2019)
摘要
Citizen Science or participatory sensing can help filling in the gaps of in-situ reference forestry data needed to analyze satellite images. In this study, we show that the Relasphone, a biomass measuring application previously developed and tested in boreal forests of Finland and temperate-cold pine forests in Durango, Mexico, can be adapted to pine forests in Asturias, Spain. Relasphone measurements were in good agreement with reference data over 20 plots (R-2 = 0:89 for stem volume) and performed well against 3 traditional relascope measuring devices. The results suggest the Relasphone can be easily deployed in other temperate biomes.
