Combining operational satellite imaging with detailed site characteristics with UAV capability enables significant reduction of costs and fast-tracking of data delivery and analysis processes for a specific area or site and verification by field surveys.
Digital Data Processing Results:

High-resolution digital terrain models (DTM);
Digital surface models (DSM);
TIN surface models;
We perform specialist image interpretation;
Digital data for geostructural mapping;
Geological anomalies, missed during geological mapping;
Data for GIS systems and subsequent geo-modeling.
Multispectral Satellite Image Interpretation
Analysis of multispectral satellite imaging materials is a tried and tested and efficient method of initial exploration of promising areas.
Field and morphometric data are interpolated to visualize a structural area plan and their detailed presentation.
We derive information on exogenetic processes, driving landwaste redistribution at surface mineralized zones.
We project field data of previous season to the territory of prospective areas.
We evaluate characteristics of conditions (ground, geomorphic) at planned sampling areas (trenching, prospect shafts, drilling) to optimize sampling density.
The most conclusive satellite sounding data are selected with regard to season of images, spectral ranges used and color combination approaches. Informational value of these satellite images is assessed not only by direct indicators, composition of rock, similar to the ones at the site, but by indirect indicators as well.
Generalization of Remote Geological and Geophysical Data with Different Spatial Resolution
Remote sensing data interpretation is structured as a hierarchy. A hierarchy is based on spatial generalization patterns of remote sensing data with varying spatial resolution implies their integration during combined interpretation of geological and geophysical information.
We use images by specific satellite systems with multiscale spatial resolution. Sensors of these satellites capture the whole field-of-view spectrum area and are supplemented by data from near infrared and shortwave infrared spectral ranges.
Moreover, after UAV aerial reconnaissance of an area, multispectral satellite imaging is enhanced with ultra high-resolution data, obtained in visible light spectrum of electromagnetic oscillations.
Why do we do this? We get:
Maps of exposure of modern tectonics and paleotectonics;
Maps of exposure of lithologic rock contacts, forming a relevant rock mass;
Maps of exposure of soft ground of mixed particle size distribution, identification of sections of ancient weathering crusts and their latest redistribution products by depositional features of modern topography.
3D localization of relict weathering crust zones may provide additional information for interpretation of geochemical sampling data to augment existing views on secondary scattering halos.
Distribution maps for glacial and slope (deluvial, deluvial and proluvial) material, to plan pit and trench network sampling.
Hypothetical spatial structure maps for hydrothermal type mineralization, for probable day surface exposures based on satellite imaging.
