Abstract
It is necessary to comprehend the both of spatial and temporal variation of ecosystem function to understand the ecosystems in basin scale. Remote sensing data with one-meter to several tens-meter spatial resolutions and daily to weekly temporal resolutions are suitable for basin scale ecosystem analysis. However, there is no such satellite sensor that meets requirements for both of spatial and temporal resolutions. It is getting important to develop the production methods of the high spatial / temporal data set for basin scale ecological science with remote sensing data, such as 1) pixel merge method with high spatial / low temporal resolution data and high temporal / low spatial resolution data, 2) improvement of temporal resolution with many scenes acquired by several high spatial resolution sensors, such as SPOT, ALOS/AVNIR-2, QuickBird, IKONOS. This paper describes the investigation of spatial evaluation of ecosystem function / structure and summary of investigation of appropriate spatial / temporal resolution of remote sensing data for basin-scale satellite ecology.
