Breaking Out of Cell Prison: Aggregate
Cell Constructs
A provocation by:
Network of Experts [N/X]
I am currently working on Aggregate
Pixel Constructs in GIS
Multivariate modeling applications
The Alternative Futures Framework
The Problem: envisioning large multivariate
spatial datasets
Local Table Maps (LTM)
[? Local Table Map: with the Geography
?]
Local Table Maps allow us to map and
record
Discussion: The rise of the Pixel --
There are however severe limitations
to using the single pixel --
Aggregate Pixel Constructs
moving away from the single cell to
cell aggregates enables the deployment of visual variables such as:
Aggregate pixel designs have a special
ability to take into account
Therefore the aggregate-cell-map maker
has control over designing elements of interpretation
Tufte stresses in his book: ãEscaping
(this) flatland is the essential task of envisioning information·ä
Creation of cell aggregates
In these image-maps the basic assumption
of each cell representing a single location is relaxed to permit multiple
cells per original location
The key step in the procedure
The addressing system is created using
spatial, arithmetic and logic operations
Use
The resultant maps reveal macro interaction
patterns,
Local table maps represent an interesting
cross
In reading a local table map, there
is an emphasis on comparing between the variables that are depicted
on the map
Our LTM shows from 6 to 9 variables:
Aggregate Cell Constructs using GIS
are applicable not only to maps,
the term Spatialization
Selected references
The term GRASP
Selected references
Examples
Concluding comments --
The aggregate cell model is unique
in that it approaches the map overlay problem in a non-standard way;
Possible Applications for Local Table
Maps:
Where Data can be:
With proper variable selection, graphic
design, and colorization
Local Table Maps represent an interesting
table/map (in image format) hybrid information representation
The two research thrusts: Aggregate
Cell Constructs and Spatialization
