Index map:

An index map in a GIS is a small map covering the entire possible geographical area of the spatial information being examined. On this map the area being examined in detail (zoomed into) is indicated.


Small images used in the Graphical User Interface or GUI of a software application that are used to represent utility functions. These utility functions can include files, folders, procedures etc. within the application. A mouse or track ball, is usually used activate the icons by clicking on them (


In a GIS, to identify, is to find information about a spatial feature by pointing to it interactively on a map with a mouse. The information is extracted from the attributes table for the active layer.


An image, also known as a picture, is an artefact used to represent some object, or a likeness thereof (


IMF stands for 'Internet Mapping Framework' and is a software application produced by Moxi Media Inc. that deploys powerful, high quality, customised web mapping applications (

Information panel:

The information panel is a window in a GIS that displays textual information about the map being used such as the list of layers, the map legend or the identity of map objects.


An intranet is a restricted-access network that works like the Internet but is not accessible to it. It is usually owned and managed by a company, institution or government department and enables the sharing of its resources with its employees without confidential information being made available to everyone with Internet access (w


The Internet, or simply the Net is the publicly accessible worldwide system of interconnected computer networks that transmit data by packet switching using a standardized Internet Protocol (IP). It is made up of thousands of smaller commercial, academic, domestic and government networks. It carries various information and services, such as electronic mail, online chat, and the interlinked web pages and other documents of the World Wide Web.

Contrary to some common usage, the Internet and the World Wide Web are not synonymous: the Internet is a collection of interconnected computer networks, linked by copper wires, fibre-optic cables etc; the Web is a collection of interconnected documents, linked by hyperlinks and URLs (

Internet Explorer:

Microsoft Internet Explorer, abbreviated IE or MSIE, is a proprietary graphical web browser made by Microsoft and currently available as part of Microsoft Windows. Internet Explorer is the most widely used web browser today, IE's usage share is about 85% (

IP (address):

An IP address (Internet Protocol address) is a unique number that devices use in order to identify and communicate with each other on a network utilizing the Internet Protocol standard. Any participating device, including routers, computers, time-servers, internet FAX machines, and some telephones, must have its own unique address. This allows information passed onwards on behalf of the sender to indicate where to send it next, and for the receiver of the information to know that it is the intended destination. IP addresses are conceptually similar to phone numbers, except they are used in LANs (Local Area Network), WANs (Wide Area Network), or the Internet. Because the numbers are not easy for humans to remember, the Domain Name System provides a service analogous to an address book lookup called "domain name resolution" or "name resolution". Special DNS servers on the internet are dedicated to performing the translation from a domain name to an IP address and vice versa (


Java is an object-oriented programming language developed by Sun Microsystems in the early 1990s. The language, which was designed to be platform independent, is a derivative of C++ with a simpler syntax, a more robust runtime environment and simplified memory management (


JavaScript is system of programming codes created by Netscape that can be imbedded into HTML to create additional functionality not supported by HTML. JavaScript programming codes allow Web developers to insert functions into Web sites such as animation and interactivity (


In computing, JPEG (pronounced jay-peg) stands for Joint Photographic Experts Group and is a commonly used standard method of lossy compression for photographic images. The file format which employs this compression is commonly also called JPEG; the most common file extensions for this format are .jpeg, .jfif, .jpg, .JPG, or .JPE although .jpg is the most common on all platforms (


A program targeting the Java platform needs two components to be present on its host: a Java virtual machine, and a set of class libraries providing any services on which it depends. Sun's distribution of their JVM and their implementation of the standard classes is known as the Java Runtime Environment (JRE) (


JSP or JavaServer Pages, known to some as the Java Scripting Preprocessor, is a Java technology that allows developers to dynamically generate HTML, XML or some other type of web page. The technology allows Java code and certain pre-defined actions to be embedded into static content
