TERRAVIEW 6000

Resource Inventory- From Satellite To Color Images

Acquiring records of the world’s resources is critical to many businesses, government agencies, and private organizations. For monitoring the growth of crops, searching for minerals, tracking water resources, or inventorying specific vegetation– numerous people depend on reliable information from remote sensing. Much of that information provided through LANDSAT satellites has been recorded on EBR systems.

The LANDSAT satellite takes “photos” of the earth at seven spectra bands and transmits them in digital form to a ground station where the raw data is recorded with high density magnetic recorders. The data is then processed into gray level raster pixels for recording each of the seven spectral bands as seven color separation image overlays with an EBR. The EBR records the continuous tone raster images on film directly from digital data and adds annotation in bit-mapped or vector graphics around the image frame. The color spectral differences sensed and transmitted by the satellite are carefully maintained and recorded on individual spectral overlay separations in perfect registration.

Correction coefficients for geometrical errors caused by satellite orbit, earth’s rotation and sensor configurations are introduced during the recording process. With its speed, high resolution, and ability to record precise color separations of the gray level spectral data with vector annotation, the Electron Beam Recorder images enable resource managers to interpret the valuable data provided by LANDSAT. The same technology can also record other types of aerial and satellite remote sensing imagery.

Why Buy A TerraView EBR?

• Flexible Output: Monotone color separations of various spectral bands, continuous tone and halftone imagery, capable of up to 20x enlargement
• Multiple film sizes: 16mm, 35mm, 105mm, 5.0 in., 9.5 in. in both framing and continuous motion film handling systems.
• Multiple film options: Silver Halide -wet processed archival quality film or processless PERM film.

How The TerraView Works

The TerraView 6000 uses a high energy electron beam generated by an electron gun, to expose either silver halide or PERM film. This beam, modulated by a high speed video coupler, is subsequently focused, shaped, and deflected using a two axis electromagnetic electron optical system. The beam is computer controlled to record multiple sensor inputs on variable image formats.

The Control and Data Processing Subsystem for the TerraView 6000 consists of a COTS computer controller; specifically a Sun SPARC Station and a Raster Vector Generator (RVG-450). The TerraView 6000 can be operated on-line, off a network (from either a hardcopy output printer or an analyst exploitation workstation), or stand alone from a media input.

These recorders can be optionally supplied with internal film punches for color registration of multispectral images.
