NaturaSat
The NaturaSat application combines geobotanical research with modern mathematical methods. It utilizes data from the Sentinel-2 satellite, orthophotos, and UAVs to identify precise boundaries of habitats, enhancing knowledge about their current distribution and spatio-temporal changes.
The software integrates various image processing techniques along with vegetation data into one universal tool, allowing for comprehensive exploration of habitats. In addition to segmentation, it also offers other tools such as monitoring, classification, transformation of historical maps, and basic hydrological modeling.

Available tools
The NaturaSat program contains a wide range of tools that enable the user to perform full segmentation of habitats and their subsequent analysis. Users can download, load, and display satellite images from the Sentinel-2 mission, orthophotos, and UAV images. The program provides tools for semi-automatic and automatic segmentation, classification, and transformation of historical maps, as well as basic hydrological modeling.
Displaying Sentinel-2 mission images
The tool allows the user to download, load, and display satellite images obtained from the Sentinel-2 mission.
Semi-automatic segmentation
Semi-automatic segmentation enables the segmentation of areas using nonlinear segments created by the user with a mouse.
Automatic segmentation
After entering parameters, the tool allows automatic segmentation using evolution from the initial polygon towards the boundaries of areas.
Habitat
monitoring
The monitoring tool enables tracking statistical changes computed from optical channels of satellite images from different periods.
Support for multiple input data
The application supports loading orthophotos, UAV data and other standard image formats.
Polygon manager
The polygon manager allows users to manage created and loaded segmentation polygons.
Classification
The classification tool enables users to classify areas using deep learning techniques.
Transformation of historical maps
The tool utilizes both local and global transformation methods to find corresponding areas on historical maps and the current interactive map.
Basic hydrological modeling
Hydrological modeling enables the calculation of the approximate height of groundwater and surface water table in river system areas.
Paid services
Training of the NatNet Networks
The classification tool is based on deep learning methods and utilizes Natural Numerical Networks (NatNets).
We offer training of the NatNet for a selected group of habitats, with consultations provided to users during the preparation of the training dataset.
Downloading and displaying satellite images
The NaturaSat application allows users to load and display all optical channels of satellite images obtained from the Sentinel-2 mission. New images can be downloaded directly through the user interface using the Copernicus Data Space Ecosystem API.
Semi-automatic segmentation
The semi-automatic segmentation tool allows users to input boundary points of an area using the mouse. These points are then connected to form nonlinear segments of a polygon, which replicates the boundaries of the segmented area. After completing the semi-automatic segmentation or closing the polygon, the resulting polygon is saved in the user interface’s list, from where it can be exported for further use.
Automatic segmentation
After entering parameters, the tool allows initiating the evolution of the initial polygon. This polygon is evolved by a mathematical model of automatic segmentation towards the boundary of the selected area. The resulting polygon and its positions during evolution are saved in the user interface’s list, from where they can be exported for further use.
Monitoring of habitats
The habitat monitoring tool enables the calculation of statistics from the intensities of optical channels of satellite images located within selected segmentation polygons. Statistics computed from different time periods can be compared, allowing users to monitor significant changes over time.
Classification
The classification tool is based on deep learning methods and utilizes Natural Numerical Networks (NatNets). The result of the classification is relevance maps, which indicate the potential occurrence of classified habitats in the input image.
