紧急应变

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.

自然灾害图

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.

环境影响图

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

人口密度图

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.

土地利用与土地覆盖图

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

设施位置图

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.

路线图

A transportation network map records all types of transportation pathways: highways, railroads, paved roads, gravel and dirt roads, paths, etc.

可达性 / 可通性分析

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.

数字地面模型 (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.

地表稳定性分析

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.

地质风险分析

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

亮度温度图

Emissivity in imagery can be adjusted to brightness temperature scales

渗漏辨识

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

污染物确定

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

沿海分析

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.

生态环境敏感性分析

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.
