Not a new idea … Design with Nature
Not a new Idea … Dana Tomlin
Desktop GIS

Generate Output Heat Map
Web is different from the Desktop Lots of simultaneous
users
Stateless environment
HTML+JS+CSS
Users are less skilled
Users are less patient
ArcGIS Server Flex, Silverlight and JS
API’s
Publish tasks and models
Caching
Optimized MSD files
But wait … there’s a problem 10 – 60 second calculation time
Multiple simultaneous users …
… that are impatient
Specific Goals File format – ARG!!
Limit range and data type
1D arrays rather than 2D
Distributed processing
Binary messaging protocol
Distributed Geoprocessing
Success!!
Reduced from 10-30 seconds to
<500 milliseconds
Success!!
Reduced from < 500 milliseconds to
<50 milliseconds

Summary New technologies are changing what can
be done
Faster geoprocessing is not just faster, it’s different
Opportunity and responsibility to re-think the user GIS user experience– Tablets– GPUs– Cloud Computing– Crowd-sourcing– Increased sampling and tracking– More corporate and gov transparency– Many, many more sensors
