NEW IMAGE NEURONET PROCESSING TECHNOLOGY FOR ENVIRONMENT MONITORING AND RESOURCE MAPPING. Dr. Vladimir E. Gershenzon General Director Research & Development Center ScanEx 22/5, L'va Tolstogo st., 119021 Moscow, Russia ABSTRACT A new approach to satellite monitoring - low cost compact ground station based on Pentium PC - Personal Ground Station (PGS) is described. The system’s complete automatization minimizes operation costs and make it possible for users to receive on-line Resurs- 01 # 3,4 (Russia) satellites (as well as Okean-O # 1 and Meteor-3M satellites) data with a resolution of 30-35x30-45 m per pixel (MSU-E scanner) and 130-150x30-45 m per pixel (MSU-SK scanner). Our suggestion would be to define the PGS as low cost complex for real-time data acquisition, which needs no special maintenance and servicing. They are based on personal computers and can efficiently operated by one operator or a researcher. In addition the cost of the passage acquisition order is 300 $ which is much less than from analogue satellites. The report presents the station specification structure and features of the station software, describes a development of a network of the stations in Russia and the perspectives of the further progress. The new developments of the Research and Development Center (R&D Center) ScanEx - the software Image Transformer for the transformation of the images into wide used geographic projections, application for Catalogue Manager for remote access to satellite images and software ScanEx NeRIS for raster images thematic processing are described . It is therefore possible for the end user not only to receive the images on his own PC. but also to prepare them for GIS processing. The thematic application of tire Resurs-0 images is wide: multitemporal environmental monitoring, forestry, agriculture, control for the hazardous territories, control for the seashore zones. One of the problems in the thematic interpretation of the remote sensor (RS) data concerning the processing of the sets of multispectral, multidate images is discussed in more details. The problem is that when we try to compare two and more RS image, we have to rectify their geometry and correct atmospheric effects. While the geometric correction could be done with high precision, the atmospheric correction for a set of images is a very complex task, and it could not be solved in a common case. A new approach, based on the artificial neural networks, for a stable RS images classification and interpretation without the atmospheric correction is described. This approach lias been realized as a part of the ScanEx image processing teclinologv in a computer program NeRIS (Neural Raster Interpretation System). Several concrete examples of this technology application in environmental protection and resource mapping are discussed. Therefore, the PGS ScanER gives the possibility of direct access to satellite information, allowing the solution of different tasks without great expenditures, which is very important for universities, geological and environmental protection organizations, etc. RESURS-Ol BRIEF INFORMATION Resurs-01 is Russian satellite series for the Earth observation. Currently operating Resurs was launched in 1994, has an ordinal number 3 and usually is referenced to as Resurs 1-3. Resurs-01 # 3 is capable of imaging the surface in two modes: either with 35 x 45 m spatial resolution within 45 km wide swath, in 3 spectral channels (from 0.6 to 1.1 microns), or with 150 x 250 m resolution, 600 km swath width, in 4 spectral channels (lying approximately in the same wavelength range). In either of the modes, the output data are transformed into a digital code with 8 bit/pixel thus providing (along with housekeeping data) 7.68 Mbit/s stream (QPSK modulation type) which is downloaded in 8 GHz and 465 MHz frequency band. The data rate is twice higher - 15.36 Mbit/s (BPSK modulation type) - for Resurs-01 #4, Okean-O # 1 and Meteor-3M. Up to the recent past, due to a high data rate and requirements to an antenna system, this kind of data were received and distributed only by special receiving centers. We present a personal ground station for Resurs-Ol that is a station affordable (from the point of view of its cost, installation, control) practically to any user - up to an individual one. THE STATION DESCRIPTION Hardware The station is based on an ordinal IBM personal computer (Pentium-166 and higher, with a sufficiently fast hard disk - approx. 3 MB/s and more). Besides of a PC, the station consists of an antenna system and PC/antenna interface. The antenna system includes: a parabolic mirror with a feeder on a rotation table, a low-noise amplifier and frequency converter mounted on the feeder.
