Remote sensing in civil works

Large engineering projects are carried out anywhere in the world. In many countries it is difficult to find updated mapping information. In these cases, remote sensing becomes an essential tool to face the projects.

From satellite images we can obtain both altimetry (Digital Elevation Models), and planimetry (roads, hidrography and land uses) from anywhere in the world.

Since 1999 several Very High Resolution (VHR) satellites have been launched providing satellite images with resolutions of up to 50 cm, which is equivalent to 1:2,500 working scale.

  • Worldwide cover.
  • VHR imagery archive since 1999.
  • Customized programming of satellites (user chooses how, when and where).
  • Images available for working scales up to 1:2,500.
  • Multiespectral Information.
  • Extraction of Digital Elevation Models, to know land variables like gradient, slope or orientation.
  • Good Cost/Information relation versus traditional techniques like aereal photography or topography.
  • Objective and reliable information that can be used as evidence in legal proceedings.
  • Integrable into GIS.
