| Abstract: | According to the field spectrum data collecting within Beijing area, some technical methods in data acquirement are discussed, which include environment condition, analysis of the character of desertificated land, strategy of sampling and selecting of instrument. Spectrum data collected by the ASD-FR field spectroradiometer has been used as an example to show how the errors in data collecting can be eliminated. Ancillary data that effect spectrum data sharing are also discussed. |
