Abstract
We discuss some of the advantages and disadvantages of satellite data for rangeland planning in Central Asia, with our emphasis being on sources of low cost or free data. The availability and use the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) as a base map and tool for coordinated natural resource planning in Central Asia is discussed in detail. Base maps are important in planning projects to help in identifying vegetation types, water sources, areas of concern (for example degraded sites), structures, for description of past and current uses, and the communication and development of a new plan. The ASTER data are currently free and use a non-continuous acquisition method so not all areas of the globe receive the same repeat coverage. ASTER data were found to have high coverage over Central Asia and “usable images,” defined as growing season images and with ≤ 15 percent cloud cover, were found for 93 percent of points sampled in Central Asia. We compare the ASTER reflectance product with two other moderate resolution data sources, Landsat ETM+ and MODIS (250 m). This paper will benefit development agencies and natural resource managers in Central Asia that may not be aware of the advantage and disadvantages of different remote sensed data or sources of data.
