The Power of Near Infrared Imagery for Mapping

The Power of Near Infrared Imagery for Mapping

Although near-infrared imagery is becoming more widely available, many users of geospatial data (even GIS professionals) do not appreciate the true power of these images. While most people are familiar with true color images, which represent visible wavelengths in their “natural” colors, false color images assign colors to one or more “invisible” wavelengths. When false color images are produced with ...
