Documentation for MultiSpec

Documentation for MultiSpec is in four forms: (1.) An introduction to MultiSpec itself, focusing on how to call its various processors and capabilities, (2.) Several documents showing how to apply MultiSpec to analyze multispectral and hyperspectral image data, (3) A text book describing in detail how to use many of the algorithms of Multispec and (4) Published papers providing research results leading to the various new algorithms and processors. Sufficient detail is provided in the first two of these, including copies of the data used in their examples, so that readers who have obtained a copy of MultiSpec may follow along the descriptions and obtain the same results. Copies of the documents and data sets may be downloaded by selecting the respective highlighted titles.

The documents are in Adobe Acrobat Format and can be read within your web viewer if you are using version 3 or later of Netscape Navigator and version 4 or later of Acrobat Reader. An Acrobat Reader for Macintosh, Windows, or Unix can be downloaded from "http://www.adobe.com/prodindex/acrobat/readstep.html".

When downloading a document via a web viewer on a Macintosh, the file will first appear on the desktop in binhex form, then it will be converted into a self extracting archive, followed by decompression. When downloading via a web viewer on a Windows system, the file will first appear on disk as a zip file and then will be decompressed. Depending on the resources available to your web viewer, some of these steps may need to be initiated manually.

1. How to Use MultiSpec

An Introduction to MultiSpec - 5/01, Acrobat file (1.9M bytes) - for either Macintosh or Windows systems.

NOTE: This version reflects the capabilities in the 5.31.01 version of MultiSpec. See the 'What's New' link to find a discussion of features added since then.

This document provides a basic tutorial on how to use many of the MultiSpec capabilities, how to ingest data into MultiSpec, and a reference section which explains the function of each item of each menu. References are also given to the research literature where details of the algorithms used in MultiSpec can be found. This document is considered mandatory for any user of MultiSpec.

Note that this document was written for the Macintosh version of MultiSpec. The capabilities that currently exist in the Windows version contain dialog boxes that are similar to those for the Macintosh version. This document should at least help until a Windows version of the Intoduction is available.

2. How to Analyze Multispectral (and Hyperspectral) Data

On Information Extraction Principles for Hyperspectral Data - 7.97, Acrobat file (260K)

This is a white paper that begins by providing a general background to multispectral data. It discusses the various ways multispectral data may be viewed, what such data is like, and general concepts for data analysis. It presents results of research into uniquie (and non-intuitive) characteristics of high dimensional data feature spaces, and provides an approach to analyzing hyperspectral data.

Multispectral Data Analysis: A Signal Theory Perspective - 8.94-Revised 4.98, Acrobat file (930K)

This document provides a sketch of the theory and concepts implemented into MultiSpec. It also follows step by step through two example analyses, one for a nine-band data set, the second for the 220-band hyperspectral version of the same data. It thus provides a comparative example of the added power of hyperspectral data over conventional multispectral data.

 

 

Multispectral Data Analysis: A Moderate Dimension Example - 7.94, Acrobat file (600K)

This document describes a 12-band data analysis, illustrating additional methods and features of MultiSpec.

3. Textbook - Signal Theory Methods in Multispectral Remote Sensing

A textbook is now available describing in detail how to use many of the algorithms of Multispec. The book is written for the senior/graduate level student or professional for all engineering and Earth science disciplines. Included with the book is a CD containing example analysis exercises and multispectral and hyperspectral data sets. The title of the book is "Signal Theory Methods in Multispectral Remote Sensing," published by John Wiley and Sons, Inc, 2003. The ISBN number is ISBN 0-471-42028-X. The book may be obtained from Wiley's web site (Go to http://www.wiley.com/cda/home and do a product search by author for Landgrebe), from other web site sources such as Amazon books, or from local book stores. For instructors adopting the book as a text for a course, an Instructor's CD is available directly from Wiley. It contains solutions to the exercises and problems, and a complete set of PowerPoint lectures.

4. Papers and Reports Providing Additional Details

Research work and further development of MultiSpec continues, and, indeed, the primary purpose of MultiSpec is to make results of this research rapidly available to the research, educational, and practitioner community. In addition to the above "how to" documents, additional documents and research papers providing the basis behind the new algorithms in MultiSpec are available as follows.

  • Publications for the last several years which are available in the open literature. Some of these publications can be downloaded as pdf documents which can be read using Acrobat Reader.
