sunday morning
started thinking weshould do something
version one
process CFA RSS feed
geocode locations
publish as an interactive map
version two
automate geocoding
auto-refresh the map
search, links to relief agencies
slight issue
Fire service data not always clean
“5KM SE WARBUTON TRK”
step three
satellite imagery
NASA MODIS
TERRA and AQUA
250m resolution
daily coverage
IR detectors
rapidfire.sci.gsfc.nasa.gov
polar orbitonline withina few hours

how to ensure accuracy, timeliness?
very real concern fordisaster-relief agencies
create clear license
lay out terms for re-use
timeliness
attribution
links
for instance
structure
attach times to data
attach locations to data
use georss
prevent misuse selectively
e.g. limit precision locating urban fires
you arenʼt the only one with a use for
your data
open data
especially when livesmay depend on it
