AGRICULTURE AND FORESTRY

Hyperspectral and multispectral data is ideally suited for agricultural and forestry applications. Some of the uses of this technology include: soil type mapping, precision farming (evaluating the optimal use of irrigation, fertilization and pesticide treatments), crop yield prediction, illegal crop detection, monitoring of deforestation/reforestation programs, etc. It is fundamental to determine the land uses in order to plan de different exploitation activities of the natural resources. Hyperspectral and multispectral imagery provide detailed information in a very fast and efficient way. Besides, HytecAltoAmericas’ airborne imaging spectrometers offer higher spatial and spectral resolution than satellite imagery, to more precisely identify vegetative species and map their status.

Crop Map

A crop map shows its vegetation type, distribution, health and probable yield.

Vegetation Map

This map shows the type and spread of vegetation. It also identifies vegetation health, the different kinds of stress under which it may live because of different levels of contamination and their source. Hyperspectral imaging is also useful for species distribution and diversity studies, illegal crop detection, etc.

Hydrographic Chart

A hydrographic chart includes all surface water, such as lakes, ponds, rivers, wetlands, marshes, aquifers and glaciers, and identifies the corresponding basins.

Soil Map

A soil map references soil types, including the inferred texture (categorized in coarse, medium and fine classes) and predominant chemical composition of the defined soil in each area.

Erosion Analysis

This product measures land erosion, which is one of the most important environmental variables to monitor in desertification processes.

Slope Analysis

This vectorial analysis determines the rate of elevation change. The slopes are generally derived from a digital elevation model. The resulting maps allow the calculation of water stream directions and their supposed velocities.

Surface Stability Analysis

A surface stability analysis is developed from soil and lithological maps, and slope analysis core products. These composite maps are useful to civil engineers in the planning of dams and general infrastructure, and for pipeline, channel, and transportation network routing.

Road Map

All types of roads, both urban and regional, are registered in the road map: highways, avenues, streets, alleys, railways, paved roads, gravel or dirt road, etc.

Accessibility / Transitability Analysis

An accessibility or trafficability map is developed from soil, lithological transportation network maps, and also from slope analysis. These maps show the ease of moving equipment and personnel from one location to another.

Facilities and Servicies Map

This map details the location of different services network and its respective facilities. It can include, for example, electric lines, microwaves transmission towers, irrigation canals, water pipe, oil and gas pipelines, cloaca, etc.

Soil Use and Coverage Map

Soil use determination is essential for the planning of several activities. Land cover maps are created by means of spectral imagery, which depicts this information in a fast and effective way.
