SUMMARY

Panchromatic images are defined as photographic films that are sensitive to all visible colors of the spectrum, distinguishing them from older orthochromatic films that are red-insensitive. In remote sensing technology, panchromatic images are associated with higher resolution compared to multispectral images, which typically offer lower resolution. This distinction is crucial for applications requiring detailed imagery, as panchromatic images provide a more comprehensive view of the landscape. Understanding these differences is essential for professionals working in remote sensing and image analysis.

Hi,sometimes I read words like panchromatic images in remote sensing technology. Is panchromatic identical with black&white?Owen
 
Physics news on Phys.org
Panchromatic is a b/w film that is red-sensitive. Older, orthochromatic films, are also b/w, but red-insensitive.
 
The definition I get from google is that panchromatic is: (of photographic film) sensitive to all visible colors of the spectrum. Not sure what it means when it comes to remote sensing technology. I'll try to look up more information when I have the time.
 
Some remote sensing systems provide two modes: panchromatic with a higher resolution and multispectral with a lower resolution, so panchromatic is always related to higher resolution.Owen
