For more accurate results, the calibration images should be taken under conditions […]

Relationship between atmospheric corrections and training-site strategy with respect to accuracy of greenhouse detection process from very high resolution imagery

20 julio, 2010 /0 Comentarios/en , /por

Fernando Carvajal Ramírez, Francisco Agüera, Fernando J. Aguilar, Manuel A. Aguilar 2010 International Journal of Remote Sensing, 31: 2977 — 2994 http://dx.doi.org/10.1080/01431160902946580 ABSTRACT Frequently, satellite images that are acquired to extract a target surface are atmospherically corrected prior to the detection process. Thus, the unification of measure units is achieved, and atmospheric effects are removed […]
