An example of the result of mixing channels in the IMC software package is given.
In the lower left corner is the original image, and in the upper right - the result of processing.
Pre-processing in the IMC PC includes:
The image passport is contained in the initial data set in text format or in the format xml. In the IMC PC, data from the passport is read automatically with the subsequent formation of a composite Images.
Information about the channels of the image is also automatically filled in: wavelength ranges, band width, gain, shift. And metadata: name of the spacecraft, time/date of shooting, sensor type, layer type, resolution, cloudiness
All meta-information is used in the subsequent processing and analysis of remote sensing data.
Before thematic processing, atmospheric correction is carried out according to the atmospheric transmission graph, which You can choose from the proposed list or download the required one.
The figure shows an image from the Landsat-8 spacecraft and an average graph of atmospheric transmission. Left image before atmospheric correction, on the right - after.
The figure shows images from the spacecraft "Resurs-P" No. 1:
An example of the formation of a seamless mosaic from several routes from the Resurs-P spacecraft is given. and Kanopus-V.
Source routes may differ in color, georeferencing, and linear resolution on the ground. The same tool refines the georeferencing for all routes, performs color correction and conducts boundary between routes so that it is invisible.
Methods of thematic processing of satellite images allow you to study images in detail and receive vector layers with attribute information, including in automatic mode. In The IMAGE MEDIA CENTER software package implements a wide range of tools for thematic processing of satellite images.
Image analysis in false colors includes:
The image shows the original image from Landsat-8 to the territory Republic of Sakha. In the second window – image obtained in pseudo colors (7-6-4).
The brightness value of each pixel of the index image is formed by
performing mathematical operations in which values are used as parameters
the brightness of each pixel from different channels of the image.
Depending on the purpose of the study different indexes are used:
For the formation of index images in the IMC PC, the tool "Calculator
channels", which allows the user to compose any mathematical formulas with
using image channels.
To calculate the surface temperature a number of auxiliary calculations are performed (spectral radiation intensity, surface brightness temperature, spectral emissivity), conversion of values to degrees Celsius and a universal temperature scale is used. To detect thermal anomalies, calculation of surface temperature, selection of areas of anomalous temperatures, vectorization objects and filling with attributive information.
Before the start of clustering, it is not known how many and what objects are in the image, and after clustering, it is necessary to decipher the resulting classes in order to determine whether what objects they correspond to. Thus, classification without training is applied:
For supervised classification, reference areas are used, which
defines an operator based on their belonging to a certain class of objects. For the next
recognition as training samples, the values of the pixels of the reference areas in
different spectral ranges. Thus, each pixel of the image belongs to
to a certain class based on sequential comparison with all created standards. At
controlled classification, information classes are first determined, and then, based on them,
The image shows the result of the classification of the underlying surfaces with image training of "Resurs-P" spacecraft, "KShMSA-SR" equipment.

The main quantities to be changed in the spectral analysis are wavelength, intensity of the reflected signal and the spatial coordinate of the studied surfaces. The IMC software implements the following spectral analysis methods:
The figure shows a hyperspectral image from the Resurs-P spacecraft, spatial spectrogram built by a row of pixels, as well as spectral graphs, received from various types of objects.
Working with vector data within the IMC software includes creating and assigning
styles for displaying vector objects, as well as the formation of classifiers taking into account the types of objects,
display scale and a set of attribute data.
The functionality of the IMC PC allows you to create vector objects of any complexity (markers, lines, polygons, composite objects).
Vector layers can be saved in international formats SHP and TAB, as well as in the internal IMF format, which allows you to store raster and vector layers with attribute information in a single document.
For a comprehensive assessment of the results of thematic processing in the IMC software,
the ability to generate reports that may contain: images, thematic maps, a legend,
graphs, charts, etc.
The image shows a report generated by the results of updating forests and forest plots based on images from the Landsat-8 spacecraft to the territory of the Kirovskaya area.
The functionality of the IMC PC allows you to create report templates that are convenient for be used to demonstrate the results of a specific task with different inputs data, for example, during multi-temporal monitoring.
