Welcome to GEOID -- Your highway to DIGITAL EARTH !
GEOID (GEOscience Interactive Databases) is a GIS based database system with menu-driven data manipulation, search, and plotting tools designed for earth scientists' use in research and education. GEOID have been designed and developed by the GIS group at Cornell University, Institute for the Study of the Continents and Department of Geological Sciences.
At the present time, GEOID has variable scale data sets covering various locations on Earth. Although, available data concentrate in the Middle East, North Africa, and the USA regions significant global data already exist in the system. During the coming months and years we will populate other regions with data sets and expand our geographic coverage.
Currently, GEOID runs on a UNIX and NT platforms and requires ArcInfo commercial GIS software. GEOID's internal data sets are kept in four categories: Geography, Geology, Geophysics, Imagery/Grids. Access to data sets is provided through menu-driven tools which eliminate the requirement of being familiar with the ArcInfo software. Majority of the tools are written using ArcInfo's AML (Arc Macro Language).
The following pages in this manual describe briefly how to use this system and show available data sets.
Menu Driven Access
GEOID provides menu driven access to its internal data sets. Access is provided through several custom designed buttons. There are two types of buttons used in the menus: check buttons and regular buttons. Check buttons are usually used in displaying any individual data sets and are activated as soon as they are checked. The regular menu buttons are used either for an action or to start up a new sub menu. The main menu includes four buttons, three of which initiate a sub menu, and one, the exit button, quits the entire program. Buttons which start up additional sub menus are indicated by three dots at the end of the function names. In the folllowing sections we go through all the buttons and describe their functions and use.
