Since its establishment in 2003 AMBISAT has been using remote sensing as an innovative tool to obtain geographical and environmental information with a view to detecting, mapping, modelling and monitoring a large number of environmental phenomena. This is one of our distinguishing hallmarks. This is achieved by the use of advanced remote sensing techniques and integrating geo-referenced data in Geographic Information Systems.

AMBISAT has extensive experience in the acquisition and management of satellite imagery, aerial photography and airborne LIDAR data, information processing, systematic product generation, results analysis and validation through field work.

AMBISAT 's experts update their skills permanently through specific training, participating in conferences and technical seminars, and actively collaborating on research projects that rely on these technologies.

A wide range of GIS and remote sensing software is used to process these data, such as ArcGIS ESRI, gvSIG, ENVI+IDL, BEAM and NEST. AMBISAT has experience in processing MODIS, MERIS, Landsat and SPOT images, CHRIS-Proba hyperspectral images, Envisat-ASAR radar images and AHS thermal imaging.

AMBISAT provides effective and quality solutions, based on customers' requirements, given the growing demand for territorial and environmental information in the field of new technologies related to Geographic Information Systems (GIS) and remote sensing techniques.

In this line, the main remote sensing tasks and applications developed by AMBISAT are:

GENERAL
  • Satellite image analysis and processing
  • Accurate generation of orthoimages, mosaics and orthophotos
  • Integration of remote sensing data in GIS
  • Three-dimensional models and virtual flights

COVER
  • Establishing ground cover and estimating surface measurements
  • Preparing and updating basic and thematic mapping
  • Specific solutions applied to the quality of inland, coastal and oceanic waters
  • Generating land usage maps for direct application to spatial planning
  • Identification, classification and quantification of irrigated areas.

MONITORING
  • Time development studies of physical and thematic variables of the land
  • Identification of changes in ground cover and characterization of their evolution over time
  • Analysis of land changes. Identification of urban expansion area and land use changes using very high definition satellite images
  • Damage assessment: impact assessment in relation to droughts, floods, pollution episodes and forest fires
  • Risk maps
  • Earth and sea surface temperature maps. Thermal pollution analysis
  • Support for major infrastructure projects. Detection and monitoring of environmentally-related conditions

MAPPING
  • Preparation and updating of maps based on very high definition satellite images to be integrated into corporate GIS.
  • Support for precision farming with very high definition images: assessment of the phenological state of farmland due to the irregular distribution of irrigation and fertilizers, delimitation of areas affected by pests and diseases
  • LiDAR Digital Terrain Model applications
  • Preparing urban topographic maps
  • Urban heat mapping

VALIDATION AND CONTROL
  • Sampling campaigns in the field and establishing control points
