EMERGENCY RESPONSE

Accidental spills of toxic material, wildfires and natural disasters require immediate action. HytecAltoAmericas’ imagery supplies near real-time information regarding the location and extent of the impact. The consequences of such catastrophic events can also be evaluated using remote sensing.

Natural Disaster Map

This product maps the extension and levels of damage on any area due to natural occurring disasters such as earthquakes, flows, twisters, volcanic eruptions, wildfires, etc. Agricultural and material losses are also estimated.

Environmental Impacts Map

An impact map assesses the damage on an area due to human activities.

Population Density Map

A population density map records population estimates that are not obtained directly, but are inferred by various methods. Dwelling-unit estimates are most useful in rural areas and third world countries. Land use and area density estimates are also used. In large cities, built-up techniques can be utilized.

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.

Facilities and Services 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.

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 transitability 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.

Digital Terrain Model (DTM)

A DTM is derived from the combination of a digital elevation model with the corresponding surface images. Such a model allows to visualize the terrain features in 3-D.

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.

Geologic Risk Analysis

This risk analysis defines probability of occurrence and dangers of possible geological hazards.

Brightness Temperature Map

Emissivity in imagery can be adjusted to brightness temperature scales.

Spill Identification

The detection of hazardous spills has always been a difficult task. Remote sensing imagery makes them easy to spot on land or water.

Pollutant Determination

The identification and mapping of pollutants is performed by means of imagery and data through multiple-variable analysis.

Coastal Analysis

Bathymetry data are also used to map and monitor tropical and coastal regions. Examples of these include water quality, coral reef mapping and storm damage assessment.

Environmental Sensitivity Analysis

An environmental sensitivity map details the sensitivity to environmental impact of the regions in the study area. These potential impacts might be natural disasters o result from human activities.
