INTRODUCTION Welcome to the Satellite Image Gallery V1.5, a cooperative effort of Intermountain Digital Imaging, LC of Salt Lake City, UT and CORE Software Technology, Inc. of Pasadena, CA. This exciting CD-ROM contains hundreds of satellite images of the earth taken by the LANDSAT satellites along with evaluation copies of several image processing and utility programs. To assist you in navigating this on-line manual, we have included an instant index. Just push F7 at any time to access this feature. The programs on this CD are designed to be run on a system running MS-DOS or Windows and having a display adapter capable of running in a VGA mode at 640x480 in 256 colors. It is possible to run this program within Windows 3.1x or Windows 95 in a FULL SCREEN mode. It may be possible to run some of the programs within a DOS emulator if you do not have a DOS based PC available, however their performance is not guaranteed. All images are stored as standard JPEG, GIF or TIFF files and are viewable with the DOS, Windows and MAC image viewing and processing software provided on this CD. Who are we? - IDI ----------------------------------------------------------------- Intermountain Digital Imaging, LC (IDI) of Salt Lake City, UT is a company specializing solving problems in remote sensing and digital mapping. As a representative for Space Imaging/EOSAT, IDI is able to provide clients with Landsat images from around the world. In addition, IDI has access to the EROS Data Center archive of public domain Landsat images. For clients who can use Landsat images from 1982 to 1989, IDI can provide images for prices ranging from US$250 to $1500. With IDI, ALL images can be provided on CD-ROM for your ease of use. IDI also provides format conversion services to convert your older satellite images into current standards. For people who want to do their own conversion work, IDI provides a suite of software utilities called SIFT (Satellite Image Format Translation) programs. These utility programs allow users to translate satellite image data from a variety of ground station formats into the newer EOSAT fast format.

CORE Software Technology has established strategic relationships with key data providers and distributors in the geographic data marketplace, including EOSAT (U.S.), SPOT (France), the European Space Agency and Eurimage, ETAK (U.S.), SOVINFORMSPUTNIK (Russia), ESRI, and U.S. Government agencies including the USGS and NASA. CORE Software Technology has offices in Pasadena, California and Annapolis, Maryland. ImageNet ImageNet is an on line image and spatial data archive access service that gives subscribers immediate search and preview functionality. ImageNet allows users to search databases worldwide corresponding to a customer's search criteria. Preview images and text description are returned for all images that match a user's specified search criteria. Once the data is located, the user can download and keep candidate records and associated preview data. Moreover, users can automatically and easily place orders for data through ImageNet. Customers can access ImageNet through a standard Internet WWW connection. ImageNet TerraSor v2.5 TerraSoar engine is designed for the organization that has the need for internal data archive management and distribution. The TerraSoar software provides a turn-key solution for search, visual preview and display.

The Grand Canyon scene is in the public domain and you are free to copy it or use it in any way you wish. For your convenience, we have generated a series of COLOR composite images of Grand Canyon in a variety of formats and resolutions. If you have a system capable of viewing these increased resolution images, you will see vivid colors and striking details not seen in browse images. We have made color composites the 321 band combination (natural color) and the 741 band combination (mineral exploration bands). The image resolutions provided are 1280x1024, 1024x768 and 800x600. The image formats are BMP (8 bit), GIF (8 bit) and TIFF (24 bit). Have fun! -------------------0-------------------- DATA - FAST format and LTWG format data files for Grand Canyon. The FAST format subdirectory has 7 image files and one header file along with a description of the Fast Format from EOSAT.

Scanned and enhanced from a high resolution color original, this unique image is available in a variety of sizes and formats to suit your needs. They are JUMBO (6397x4214), LARGE (4798x3160), MEDIUM (3199x2107) and SMALL (1599x1053) and 640x480. These are free files which are ideal for presentations, multi- media, illustrations, graphics work or educational projects. All images are stored as JPEG files, some as GIF files. -------------------0-------------------- WORLD - Eighty browse images from around the world including scenes from Landsat, SPOT and Russian satellites. These are "preview" images generated by CORE Software and provided on their IMAGENET interactive image library system. LTWG Images Background ----------------------------------------------------------------- LTWG is the acronym for Landsat Technical Working Group which which developed this commonly used specification for formatting and distributing Landsat TM images. This format was replaced at many Landsat ground stations by the EOSAT fast format specification. Because of computer hardware and software limitations when the LTWG specification was developed in the early 80's, the Quadrant scene format was usually used. This format split each Landsat scene into four quadrants which could be individually processed. Because of recent developments in computer hardware and software, it is now preferable to process full scenes at one time. This is where QUADConvert(tm) comes in. For more information ----------------------------------------------------------------- For more information on the LTWG specification please contact Customer Service at Earth Observation Satellite Company, 4300 Forbes Boulevard, Lanham, MD 20706-9954 - TEL: US, Canada, VI (800) 344-9933 - International 01-301-552-0537 - FAX: (301) 552-3762 - TELEX: 277685 EOSAT Fast Format Specification Background ----------------------------------------------------------------- The Fast Format specification was developed by EOSAT in 1989 to provide an easy to read image format with a minimum of overhead data. Data in the fast format is delivered as raw image arrays (no header information contained in the image files) with an accompanying header file (written in ASCII). Fast Format Image Directory ----------------------------------------------------------------- To allow you to see the final quality of QUADConvert, we have converted all 7 Landsat bands of Grand Canyon. The Fast Format header file and an ASCII header have been generated by QUADConvert.
