The fundamentals of which remote sensing work are based on the electromagnetic spectrum. Using active or passive sensors, this technology lets us know much more than the human eye can.
To evaluate terrain conditions in remote or urban areas, detect any potential operational problems, and ensure that radio communication and telemetry signals can be maintained. DEMs and high resolution orthorectified satellite images are used to produce a representation of the local terrain conditions, without ever leaving the office.
utilizing stereo IKONOS satellite image data, Satellite Imaging Corporation can
provide customers with 5m digital surface models (DSMs), 2m digital elevation
models (DEMs), and a detailed, orthorectified satellite image mosaic at 0.8m
DEMs are also provided from the HRS SPOT-5 satellite sensor with a resolution of 20m, and from the stereo ASTER satellite sensor with a resolution of 15m. This data provides explorers and operators with 3D imagery and provides a substantial improvement in the visualization of surface and exploration targets.
The benefits are readily apparent, for example, in the field of oil and gas exploration. By combining the described process with interpreted seismic data in the vertical dimension, a greater understanding of the relationship between surface and subsurface structures can be achieved at both basin and prospect scale. This understanding is further enhanced when it is viewed in an immersive 3D visualization environment.
These services allow project planners, operation managers, and logistics managers to plan field operations in a computer environment, ensuring that the best access is provided and project objectives are achieved for:
Engineering and construction of pipeline, transmission, and road design
Oil and gas exploration and production activities
2D/3D seismic data acquisition
Motion pictures and media
In order to provide 3D terrain modeling and visualization capabilities within a GIS or mapping computer environment, high resolution orthorectified satellite image data must be available or acquired from the 0.62m QuickBird, 0.81m IKONOS, or 2.5m SPOT-5 satellite sensors. In some cases, digital ortho aerial photography may also be used.
If a 3D terrain modeling and visualization application requires good detail pertaining to the terrain features and terrain slopes for critical project decisions, an accurate digital terrain model (DTM) must be available. If there is no suitable DTM available for the areas of interest (AOIs), then a DTM can be acquired by some of the following satellite and aerial sensors:
LiDAR (Light Detection and Ranging)
Stereo Aerial Photography
IFSAR (Interferometric Synthetic Aperture Radar)
Stereo High Resolution Satellite Image Data
The above remote sensors are listed in order of their resolution, capability, and accuracy.
