Remote Sensing

Every remote sensing project has specific requirements, and HJW can provide the consultation to determine what spatial resolution, spectral range, sensor and analysis methods are right for your project.
HJW is a reseller of Space Imaging, provider of satellite data from the IKONOS, IRS, and IRS RESOURCESAT sensors.

We have extensive international experience with satellite-based modeling and classification, particularly in the areas of land-use mapping and baseline studies for remediation efforts. In addition to satellite imagery, our remote sensing techniques are also applied to airborne infrared photography, which has proven to be highly affective in permeability studies. 

 

  By applying our unique family of hyperspectral signatures to a pumping facility (located in an area known to contain oil seeps), we are able to show evidence of oil-impacted surfaces (red areas).
