PANCHROMATIC IMAGERY [2 records]

Record 1 2007-01-31

English

Subject field(s)
  • Spacecraft
  • Remote Sensing
DEF

A sensor with such a design as to give it the capability to be operated at different ground resolutions from the same altitude (e.g. satellite orbit).

CONT

Based on these requirements, we have implemented algorithms to extract road networks within a hierarchical cell based mathematical structure called Generalized Balanced Ternary. In this paper, we define GBT and describe how it can be used to integrate imagery from multiple, multi-resolution sensors, to make use of the panchromatic and multispectral nature of the imagery, to work at different scales, and to process the data efficiently.

CONT

If the pushbroom sensors are capable of starboard and port viewing, SIS [Sensor and Instrument System] could be designed for simultaneous broad area searches and rapid motion detection. By positioning the panchromatic scan line slightly ahead of or slightly behind the multispectral scan line, the sensors could perform a broad area survey and then the two acquired images could be digitally merged together to detect rapid movements. This technique has been applied to SPOT imagery.
