IFSAR stands for Interferometric Synthetic Aperture Radar. Developed just in recent years, IFSAR is a powerful approach in generating high-resolution digital data through the use of Digital Elevation Model (DEM) and an orthorectified radar image. The use of this technology is ideal for cost-effective, large-area geospatial solutions that are more accurate than the typical satellite-acquired data.

In partnership with the biggest IFSAR Data Provider, INTERMAP Technologies that operates a globally operational airborne IFSAR system, Certeza provides a full complement of solutions that require fast and accurate elevation data.

Our IFSAR products provide accurate digital elevation models (DEMs), high-resolution .625m images, and supplementary thematic layers that are best suited for mapping projects with scales from 1:10,000 to 1:50,000. All these products are accurately geo-referenced to provide a foundation for spatial data infrastructure requirements. When supplemented with satellite and LiDAR or optical products, Certeza can provide you with an integrated 3D mapping solution that spans the full range of end-user applications.

The high-quality 3D digital mapping data created with IFSAR technology meets the demanding needs of a wide range of market, such as:

  • Defense and National Security
  • Natural Resource Exploration
  • Telecommunications
  • Engineering and Infrastructure
  • Risk Management
  • Water Management

Our wide range of IFSAR products includes the following:

  • Digital Surface Model (DSM): a topographic model of the earth’s surface that includes natural terrain features, as well as vegetation and cultural features, such as buildings and roads. The key benefit of the DSM is that it provides the accurate elevation needed for geo-referencing all subsequent layers.
  • Digital Terrain Model (DTM): a topographic model of the bare earth that has had vegetation, buildings, and other cultural features digitally removed, enabling users to infer terrain characteristics possibly hidden in the DSM.
  • Orthorectified Radar Image (ORI): the .625m ORI created with our IFSAR provides the highest-resolution images available from either airborne or satellite platforms. The high resolution images are ideally suited for interpretation and feature extraction, enabling more accurate topographic line mapping and GIS data compilation.
