Image Quality 
Using of adequate filters. 
Images should be with a brightness, 
contrast, tonality and illumination 
satisfactory, color without clouds, risks 
and others. 
- Film exposed with a quality control color target 
- Visual Inspection of images. 
Images with clouds cannot be 
accepted, except in areas that 
cannot use for mapping.
