Hyperspectral mapping records reflective-emission surface properties in the narrow range of the electromagnetic spectrum. As a result, multi-channel image is being formed, which enables to precisely identify vegetation cover, soil, artificial structures peculiarities and assess their condition. Such image has far greater capabilities than conventional optical image. Any tiny changes and anomalies of object physical properties can be detected by hyperspectral mapping.
Example of using
The fields in rural area called Sinkovskoe were surveyed with the use of hyperspectral camera. Image in visible range.
Fields of various crops were detected.
The following crops and areas of their growth were detected:
- Weeded potato (Solanum)
Use of a green phytomass index MTCI (chlorophyll index) for crop identification and field heterogeneity
- The potato fields are highly weeded, mostly solanum. Crop yield will be extremely low. It is recommended to use weed control agents (selective or nonselective action).
- Cabbage fields condition is satisfactory. There are few nonproducing sections, which did not have seedlings, or the crops died for some reason.
