negative aspects of geospatial tech.

Question 1

cloud cover

Answer 1

-can hamper the analysis of some aerial images.
-some remote sensing tools lck sensitivity to reliably detect and measure aspects of forests.
-problematic in rainforests - which have a lot of moisture in air.

Question 2

cost $$

Answer 2

-high resolution images and various technologies used to collect, collate, record + disseminate spatial data are very costly.
-mostly rely on provision of advanced + expensive computer infrastructure networks

Question 3

cannot distinguish variations

Answer 3

-some sensors cannot distinguish between dense woody shrub land + forests.
-E.G; estimating the contribution of deforestation to carbon emissions is challenging.
-due to variation in the type of forest
as well as other physical factors
-(widely varying figures produced for ecosystem service)
