Yet another interview with the GIS Scientist ... David Maguire ...
Editor Maria Pellegrini talked to ESRI’s Chief Scientist, David Maguire, about the
exciting future for spatial analysis and evolving tools for 3D and 4D.
GEO: What 3D and 4D functionality is available within GIS in general and
ESRI products in particular for geo-spatial risk analysis? For example, one
interesting presentation at the ESRI San Diego conference was about
radioactively contaminated soil. How would spatial analysis be used for
something like that?
DM: Historically ESRI has been very strong, like the rest of the industry, on
representing 2D data structures and looking at what I call “static, deterministic
map modelling”. But at ESRI we have already started and we will
continue aggressively to refine our work on extending static 2D modelling
and analysis into 3D, incorporating the elevation values, and also into 4D,
incorporating time values, so that users can create proper space/time
ArcGIS can represent, analyze and display 3D data. There are a number
of tools we have just introduced in 9.3, our current shipping release, to calculate
3D buffers for proximity analysis and 3D overlay processing (identity, and
overlap and intersection). We already have a good framework for looking at
how things change over time by examining the dynamics of different
datasets including using animation and other visualization techniques.
Since the ArcGIS 9.2 release, we have had the ability to include randomness
in models (in terms of random functions, random distributions and also
random activations of values) so we can deal with stochastic (probabilistic)
processes and events and objects. [...]
