This paper is a memoir that summarizes the thinking that went into these data models and explores how properties and deficiencies of one led to the other.
It does not present any breakthroughs or new applications. Rather, it documents inventions that influenced subsequent developments of discrete global grids, and might still do so. Content from this work may be used under the terms of the Creative Commons Attribution 3.

We have a dedicated site for Germany. When spatial data is digitized for use in geographic information systems and other software, information about its original scale, resolution and accuracy is frequently lost.
Discrete global grid
As a result, using such information at different scales and combining it with data from other sources may be difficult. Mapping vector data at smaller than the original scale requires its generalization, which is usually handled by post-processing in ways that are only weakly supported by databases.
