GIS in the Rockies keynote presentation, September 15 in Loveland, CO. Much common content but slightly longer than the one I gave at NSGIC a couple of days previously.
27. Sparse data Sparse data
Trucks
Outages
Jobs
Often don’t need
detailed “GIS” maps
KML and GeoRSS
are good formats
28. KML
is child’s play!
<?xml version="1.0" encoding="UTF-8"?>
<kml xmlns="http://www.opengis.net/kml/2.2">

30. You can use KML in lots of places
KML uploaded to GeoCommons and used for thematic mapping
31. KML
flic.kr/p/8eZBZk
The Good
Simple
Good for sparse and dynamic data
Works with multiple platforms / products
32. KML
The Bad
Hard to match
GIS styles
Hard to scale to large
data volumes
flic.kr/p/6hwSwn
34. Raster map tiles
Pre-render maps into image files
Approach used by Google, Microsoft, etc
Very high performance and scalability
Easy to integrate with Google Maps etc
35. “If a dataset available on the web is in
a format that can't be indexed by
Google, does it make a sound?”

105. What about quality?
Dr Muki Haklay of UCL
“OSM quality is beyond good enough, it is a product
that can be used for a wide range of activities”
Based on a detailed analysis
