Forestry

The mapping of plants categories is an essential tool for the forest industry (management, fire, resource, procurement, certification), but also a valuable source of information for many other subjects: landscapes and amenities, biodiversity and  environment.

We are surrounded by electromagnetic radiation with only a fraction stimulates our senses. The part of the infrared afer the visible and which does not exceed 1400 nm is the near infrared

The simultaneous acquisition of the visible spectrum and near infrared will allow a finer classification of plant species. For example, the different stages of senescence of the same species can be distinguish. In the visible spectrum due to the replacement of chlorophyll by brown pigments and in the near infrared because of the disruption of the internal structure of the leaves.

APEI can quickly perform acquisitions at very high resolution to a resolution 2.5cm / pixel 5 channels (R, G, B, panchromatic and infrared.)

All these data coupled with GNSS and inertial data allows to georeference a very precise images.

Afterwards different algorithms, can produce various technical indexes such as soil brightness index, the vegetation or the water stress index.

These analyzes are used mainly to define an optimization plan inputs (fertilizers, pesticides or irrigation) and optimization of the harvest (yield estimation, prediction of the best times to harvest).

Applications:

  • Index calculations NDVI, EVI for a Council nitrogen amendment
  • Mapping / surveying and orthophotos
  • Monitoring and follow-up crops

Control grants payment

In application of European regulations governing the system of agricultural subsidies, payment organizations use remote sensing for control of the areas declared for the payment of subsidies.

APEI is really experienced in this field and performs RGB simultaneous acquisition and Near Infrared in a very short time.
