Cartography, GIS and Remote Sensing

Over 20 years of experience in GIS and remote sensing applications makes S2S can perform any mapping project or geographical analysis. Note the ability to produce 3D mapping anywhere in the world, as well as any application where satellite imagery can be an indispensable tool.

  • Ship detection
  • Oil spills cartography
  • 3D Cartography, digital elevation models (DEM)

  • Thematic Mapping
  • Multitemporal analysis, change detection
  • DIFSAR (Differential Interferometric Synthetic Aperture Radar)

Applications

Applications of cartography and satellite imagery are numerous. Following are some of the most popular applications where S2S team has huge expertise using digital mapping and satellite imagery.

Activities based on the use of satellite images and information handling by a Geographical Information System are able to develop an Environmental Monitoring System for oil industry. The most important environmental impacts of the onshore Oil Exploitation are related to oil spills and vegetation and soil loss due to the construction of the infrastructure (accesses, pads, pipelines, etc). With multispectral satellite images is possible to map the oil spills and infrastructure development in any area over the world. This allowed analyzing the development of pollution and infrastructure growth.
cartografia3D from satellite images Satellite imagery and aerial photographs play an important role in general mapping, as well as GIS data acquisition and visualization. Estimating terrain relief from spatial stereoscopic pairs of images using image matching algorithms is a validated technique. It has been used for more than 15 years operational to produce Digital elevation Models, i.e. altitudes given on a regular ground grid.
Satellite Image Thematic Mapping Digital image classification uses the spectral information represented by the digital numbers in one or more spectral bands, and attempts to classify each individual pixel based on this spectral information. For example, Land cover, vegetation, soil types and water quality map can be generated from satellite images.
Fragmentacion multitemporal The synergistic use of multi-temporal remote sensing data and advanced analysis methodologies results in the possibility of solving complex problems related to the monitoring of the Earth’s surface and atmosphere. Today, we have big data bases of satellite images which give us the opportunity of study changes in land cover maps, urban growing, environmental index, etc.
GIS applications are very diverse, S2S has the capability of carry out any kind of project. Other applications are: shipping detection for maritime security, DIFSAR (Differential Interferometric Synthetic Aperture Radar) is very useful for subsidence studies.
