السلوك الطيفي للمعالم الارضية في مناطق الطيف الكهرومغناطيسي

الملخص EN

This research aims to study the spectral signature in the regions of the electromagnetic spectrum by using a Spectroradiometer device type FieldSpec3 which produced by American ASD company.

Spectroradiometer device was designed to work in ranges similar and close to those ranges adopted by the satellite images.

The FieldSpec3 Spectroradiometer device designed to work within ranges (the visible region, near infrared, shortwave infrared 1, shortwave infrared 2).

Through this study the Spectroradiometer device will be used to measure the spectral signatures of some of landmarks that represent the major varieties of land cover (e.g., soil, vegetation, cement, asphalt, water).

This study showed that many of features of land surface in this research can be recognized depend on its spectral characteristics such as in case of recognition between concrete and asphalt etc.

Thus, using spectral curves behavior by Spectroradiometer device need to understand the spectral characteristics of features.
