摘要:
This paper discusses the pitfalls of classifying satellite images using automatic classifiers. The discussion is illustrated by application of quadratic and linear discrimination to high resolution data produced for the National Remote Sensing Centre campaign. Within the training set there is good discrimination between most land uses, but the lack of agreement between overall results of discrimination for the two discriminators shows that measures of accuracy based on accuracy within the training set can be misleading. Cross-validation of the quadratic discriminator and calculation of between and within site measures of spectral variability also illustrate how the usual calculations may give over-optimistic measures of discrimination accuracy and spectral variability.

摘要:
An inexpensive microcomputer system has been configured to process and display Landsat-MSS digital data for higher education establishments. The system consists of a 16-bit processor with a maths co-processor, a 512 kbyte memory with 20Mbyte fixed disk drive, 1·2 Mbyte diskette drive, keyboard and enhanced colour monitor. A graphic development tool kit is installed to display an image. To enable data transfer to and from the mainframe computer, communication software is made available on both the microcomputer and the mainframe. This local work station is capable of carrying out both graphic work and image processing.

摘要:
Good agreement is demonstrated between both L-band and X-band SARSEX internal wave image data and the predictions of a new radar ocean imaging model that incorporates Bragg, specular, and composite scattering effects. It then follows that a two-step hydrodynamic modulation process, as hypothesized by Hughes and Gower, Thompson and Gasparovic, and Watson, does not appear lo be required to explain why the SARSEX L-band and X-band internal wave image modulations are comparable.
