These maps are vector based, where map features are referenced as points.
That keeps the file size small, but screen drawing time long
Conventional Mapping
They define a horizontal direction of Longitude where the surface of a sphere is divided into 360°.
They define a vertical direction of Latitude where a hemisphere is divided into 180 °.

The Infinite GridSM divides Longitude and Latitude into tiles of area. All features and information are referenced by area, not by vector.
The Infinite GridSM
The difference is subtle - but very far-reaching

The Infinite GridSM highest level (IG0) encompasses the whole globe in one tile.
This is divided into 9 X 9 tiles, each covering 45 ° Long. and 22.5 ° Lat. for level IG1.
Each IG1 tile is in turn divided into smaller tiles, and at IG8 each tile size is approximately 11.8 x 6.9 ft.
The Infinite GridSM
Each tile is reference by the tile number vertically and horizontally at each level. Thus an IG1 tile might be 23. An IG2 tile might be 14.46. An IG3 tile might be 21.45.33, etc.

Why not use Longitude & Latitude references instead of
Infinite GridSM references?
1. Since Longitude and Latitude already describe map axes, a separate reference scheme is needed to describe areas.
2. Only two single digits are needed to indicate each tile for an IG (Infinite GridSM) reference.

This arrangement allow XML referencing of all data that can have an IG reference attached to be displayed together.
That means that a common access format solves all the problems of combining mapping and spatial data together.
It also puts the power in the hands of the average user - to relate data from disparate sources directly on the desktop.
Why is all this important?

Before the spreadsheet was invented, business financial planning and reporting was the domain of experts.
NOW, the power is in the hands of the average user. This has restructured business radically.
Could it really make a difference?

Before the Internet, business intelligence was difficult to collect.
Who buys anything, now, without getting all the pertinent information, and comparing the competitor’s products before buying?
Remember the days before the Internet?

Giving access to data is a mandate for many sectors of government. Selling data is the value point of business. IG and the internet creates the ideal connection tool for both.
XML allows content to be directly located by search engines
XML coded IG data and graphics make the internet a magnificent access tool to extract relationships between all kinds of knowledge
Infinite GridSM and the Web
