The use of high- and very-high-resolution multispectral satellite data, combined with specific GIS and Remote Sensing expertise, along with the support of its scientific collaborators and, where necessary, the use of ground surveys and/or other data sources, enables Iptsat to offer high value-added solutions and services and to design new ones based on client needs.
GEOREFERENCING
Two-dimensional image correction process capable of associating known real-world coordinates to an object within the image.
ORTHORECTIFICATION
Three-dimensional image correction process (more accurate than georeferencing) that allows the correction of remote sensing images, particularly minimizing distortions occurring during acquisition and those related to the instrumentation used.
RADIOMETRIC CORRECTIONS
Correction of effects caused by sensor sensitivity and varying lighting conditions.
ATMOSPHERIC CORRECTION
Distortions in radiance values occur due to the passage of signals through different atmospheric layers. Atmospheric correction removes these disturbances. It is especially important for the comparison and analysis of multitemporal datasets.
PATCHWORK AND BALANCING
Our software enables the rapid generation of homogeneous mosaics from multiple images. By adjusting color balance, excellent results can be achieved even when starting from radiometrically different images.
AGRICULTURAL INDEX MAPS
Quantitative analysis of vegetation spectral behavior allows discrimination between vegetation and other land uses, using algorithms based on typical absorption and reflection spectral bands.
THEMATIC AND DERIVED MAPS
Value-added information can be extracted from thematic or derived maps through remote sensing data processing, classification, and photointerpretation. Examples: land use maps, vegetation maps, slope maps, temperature maps.
CHANGE DETECTION
Change Detection is a satellite image processing technique aimed at identifying transformations in a given area over time.
ORTHOPHOTOCHARTS
An orthophotochart consists of a satellite ortho-image framed within a cartouche. A kilometer grid, geographic grid, and cartouche with additional information are essential to facilitate its use and reference within a chosen coordinate system.
CARTOGRAPHY CREATION AND UPDATING
Vector patterns of geographic databases can be updated through 2D and 3D cartographic restitution. Examples: CTRN, topographic databases, etc.
3D ORIENTATION OF STEREOSCOPIC IMAGES
Stereoscopic vision allows the perception of three-dimensionality. Oriented images enable 3D visualization and preparation for 3D data extraction, including elevation models and objects derived from photogrammetry.
DEM (Digital Elevation Model)
A DEM represents the territory or another surface in digital format. Typically produced in raster format, each pixel is associated with its absolute elevation. Example: NTT DATA ALOS DEM / DTM 5m.
DTM (Digital Terrain Model)
When modeling the terrestrial surface, a DTM (Digital Terrain Model) is used. It is a specific type of DEM representing the ground surface. Example: NTT DATA ALOS DEM / DTM 5m.
The use of high-resolution multispectral satellite data (Planet, GeoEye, IKONOS, WorldView, SPOT, etc.) combined with GIS and Remote Sensing expertise, support from scientific collaborators, and, where necessary, ground or other data sources, allows Iptsat to provide high value-added solutions and services, and to develop new projects tailored to customer needs
