PEASE FORTRAN 77(80%),C-LANGUAGE(15%),ASSEM- BLER(5%) Approximately 200,000 source statements 9 Track 1600 BPI DEC VAX BACKUP Format Magnetic Tape DEC VAX Series GSC-13075 Price: License $5,000.00/Documentation $300.00 (Program Available By License Agreement Only) The Land Analysis System (LAS) is an image analysis system designed to manipulate and analyze digital image data and provide the user with a wide spectrum of functions and statistical tools for analysis. LAS provides a tlexible framework for algorithm development as well as the processing and analysis of image data. LAS functions include various image analyses such as clustering, classification, film processing, Fourier transforms, geometric registration, image repair, radiometric correction, and manipulation of image statistics. Data files accepted by LAS include formats such as LANDSAT, Thematic Mapper, and EDIPS. Geometric transformations include correction of LANDSAT distortion, grey-1evel correlation, mapping grids, coordinate system conversions, and other general cartographic transformations. LAS can repair broken lines by averaging, correct for cyclic offsets, and perform various pixel manipulations. The program provides functions for intensity transformation and multispectral processing. LAS graphical output is designed for the Versatec plotter. The program also supports two display systems under VAX-supplied commands: the International Imaging Systems display processors, and Hazeltine Interactive Analysis terminals. LAS will process images of up to 8196 pixels per line, with 8196 lines per image band. The LAS application programs are integrated under an interface called the Transportable Applications Executive (TAE). TAE has four modes of user interaction: menu, direct command, tutor (or help), and dynamic tutor. They allow users, from beginner to expert level, to exercise specific application options. TAE contains a subsystem to manage its cataloging and filing systems. The Catalog Manager (CM) is responsible for hierarchical file access and maintenance through TAE. The LAS package is available by license for a period of ten years to approved domestic licensees. The license fee includes the source code to LAS; the TAE and CM programs; and one complete set of supporting documentation. Additional copies of the documentation may be purchased separately at any time. LAS is written in FORTRAN 77, C, and Assembler for interactive execution and has been implemented on a DEC VAX 11/780 computer operating under VMS 4.0 with a central memory requirement of approximately 80K of 8 bit bytes. LAS requires use of the IMSL scientific subroutine library for full implementation, and an array processor is recommended. This program was developed in 1986 and updated in 1987.
