Agriculture
Earth remote sensing satellite systems enable to make high-resolution imaging
The system capabilities
- Detection of field boundaries and work areas calculating the acreage;
- Detection of used and unused agricultural lands (arable lands, forage lands, and perennial plantings);
- Detection of the lands suitable for integrating into the crop rotation;
- Determination of the level of field colonization by tree and shrubbery vegetation;
- Detection of appearance and condition of crops, weeds, and diseases;
- Determination of the need for fertilization;
- Detection of the actual use of agricultural land (shelterbelts, private smallholding, gardening, countryside houses building, private house building, farming);
Example of use
About mapping
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)
- Cabbage
- Corn
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.
