Review all article using OGC standard

[edit]

The new OGC DGGS standard entitled “Topic 21: Discrete Global Grid Systems Abstract Specification” is online! It includes important information on definitions, conventions, functional algorithms, the core data model and more... see:

grabularity

[edit]

What does grabularity mean? Should this be granularity? — Preceding unsigned comment added by 67.188.178.167 (talk) 03:19, 15 December 2018 (UTC)[reply]

About flat and hierarchical grids

[edit]

The term "flat" is perhaps preferable to the term "non-hierarchical". See "flat vs hierarchical" organizations, design architectures, clusters, structures, etc. About properties, see this didactic article comparing both for spatial-partition in games, as decisions:

  • flat grid, advantages:
    • Simpler: the flat data structure is simpler, and it is simpler to implement.
    • Memory usage is constant. (spatial partition can often be fixed ahead of time).
    • Faster: it can be faster to calculate or update, when objects change their positions.
  • hierarchical grid, advantages:
    • It handles empty space more efficiently.
    • Neighboring objects can be moved quickly.
    • The partitions can be imbalanced. When objects clump together, you get better performance, avoiding to waste memory in the empty areas.

Grid classification

[edit]

It is possible to adapt Grid classification article, and generalize relationships of the DGG areas...
