HytecAltoAmericas’ enhanced data enables our analysts not only to detect pollution, but also to differentiate its type, distribution and sources. We can also define the effects that contamination has on environment from observations of vegetation stress, chemical changes in soil and thermal variations in terrestrial surfaces and water bodies. Risk analysis maps are used to delineate areas sensitive to potential damage. Time-sequential studies characterize the evolution of ecosystems and habitats in regions of high environmental susceptibility. In order to carry out this kind of studies, it is possible to use the analysis of various environmental components, such as soil, vegetation and water bodies, among others. Also, multiple variables are analyzed, which may modify the physical and biological conditions of environment (weather phenomena, erosion levels, farming activities, population and urbanization, industrial installations, transportation network, etc.). Therefore, it is possible to determine the environmental baseline by quantifying the initial state of all of these components.

植被填图

Vegetation maps show the type and spread of vegetation. It also identifies vegetation health, and the different kinds of stress under which it may live because of different levels of contamination due to hydrocarbons or other pollutants. Hyperspectral imaging is also useful for species distribution and diversity studies, illegal crop detection, etc.

水文图

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

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.

土壤图

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.

侵蚀图

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

现场原生态图

An environmental baseline is developed from crop, urbanization rate, vegetation, and hydrographic maps. It is designed to show the condition of the environmental variables in an area at a certain point in time, typically before the intrusion of industrial activities. In the development of a wide variety of industrial projects it is important to know the initial state of these variables, to be able to identify and quantify possible changes. Hyperspectral technology has been tested to be extremely useful for such studies in hydroelectric, mining and hydrocarbon projects.

时间变化规律分析

This core product is a measure of how the resources of an area have changed over a period of time. This analysis is done by means of multi-temporal multispectral and hyperspectral, using several processing methods, such as simple image differencing, image regression, post-classification comparison, etc.

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.

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.

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.

环境影响填图

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

土地利用与土地覆盖图

The determination of the soil uses is essential for the planning of different industrial activities. Soil coverage maps are obtained through the information provided by spectral images in a rapid and efficient way.

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.

城市化填图

This can be considered a subvariety of the change detection product. Not only does it map urban areas, but it also compares them to previously available data, so as to identify changes and to estimate the urbanization rate.

众居地辨认

This product identifies encroachments and compares this data with the previously available information to map changes and estimate this settlements growing rate.
