Remote sensing imagery Interpretation & spectral analysis - is the process of recognizing objects and territories, their properties, and interrelations based on their images in the captured satellite or aerial imagery.
Decoding of can be done through fieldwork or through office work. Office decoding is further divided into visual and automated decoding. Visual decoding is performed manually by an interpreter who visually identifies and decodes the objects on the image.
Automated decoding (machine decoding) is performed by an interpreter using specialized software and algorithms. Machine decoding involves various methods that group objects based on certain decoding features and essentially boils down to different classification mechanisms. Image classification can be categorized as supervised classification (Minimum Distance Method, Spectral Angle Method, Mahalanobis Distance Method) and unsupervised classification (ISODATA Method, K-Means Method).
The Importance of Remote sensing imagery Interpretation & spectral analysis
Decoding remote sensing materials (satellite and aerial images) is conducted to obtain information about the spatial distribution of geographic objects, their occupied areas, and to identify the dynamics and characteristics of such objects.
Depending on the tasks to be accomplished, decoding of satellite images can be classified as general decoding (comprehensive or geographic) and specialized decoding (thematic or specific).
Interpretation & spectral analysis satellite images involves preliminary and main stages, which include data processing, brightness normalization for different object types, creation of mosaic coverages, etc.
The results of decoding are documented in graphical, digital, or textual formats.

FAQ
- acceptable accuracy of spatial geolocation of images;
- spectral range of shooting: panchromatic, multispectral (color), color with near-infrared channel, color with short-wave near-infrared channel;
- the angle of deviation of the image from the nadir, for example, up to 20 degrees or up to 10 degrees;
- radiometric resolution of images, for example, 8 bits /16 bits (the higher the resolution, the more brightness gradations can be seen in the image);
- the percentage of clouds in the image, for example, is no more than 20%;
- snow cover in the images (20% of the area).
If space image processing is required, the requirements are discussed with the Contractor.
