The system should provide for easy import of data in a variety of formats, and easy export of results, both in thematic map and in tabular form. In the following chapters, how to use MultiSpec for LANDSAT data analysis is. San Fernando Valley Lab PART 2: Introduction to Using MultiSpec SoftwareMultiSpec is a multispectral image data analysis system developed by Purdue.The system should be easy to learn and easy to use, even for the infrequent user, using the most modern of software environments.The implementation should be on a readily available computer platform which has adequate processing power, but is financially within the reach of any Earth science researcher (i.e., computer platforms For this tutorial we will use two images of Durham, New Hampshire (USA). MultiSpec© is used in The GLOBE Program to analyze Landsat images and to prepare digital land cover maps. The exercises and activities that follow can be conducted without fully understanding the NDVI formula, the spectral data that are used in its development, and why NDVI highlights vegetation density differences. comfortable with the software MultiSpec©, produced at Purdue University, and distributed freely on the Internet.

MultiSpec Tutorial 5 Combining Separate Image Files of 10 Revised 5.1 Multiple selection approach: For this approach, one selects all of the images to be linked at one time in the Open Image File dialog box before selecting the Open button. MultiSpec satisfies the following design goals: Biehl, 1995: An Introduction to MultiSpec.

There are currently in excess of several thousand known, registered users. It has also found significant use in other applications such as multiband medical imagery and in K-12 and university level educational activities. The primary objective of MultiSpec is as an aid to export the results of our research into devising good methods for analyzing such hyperspectral image data. MultiSpec is a processing system for interactively analyzing Earth observational multispectral image data such as that produced by the Landsat series of Earth satellites and hyperspectral image data from current and future airborne and spaceborne systems such as AVIRIS.
