Using Small Data in Buffalo and other Government GIS News
Turns out, too much data can stall action whereas "just enough" can cause action. That's what they are finding in Buffalo, NY.
The amount of data was not huge by big data standards; for instance, the 311 system in Buffalo gets about 300,000 calls a year. Still, Christopher Conlee, GIS specialist in Buffalo's MIS department, found that a year's worth of calls, mixed with crime report and housing violation data, was useless. "You get to a certain point where you have too much information on a map and it loses its value," Conlee said. "You can make any correlation or see any types of trends you want at that level."
It took Conlee a day or so of working with the data to find that limiting the data set to six months gave the best picture of the city's issues. He created two maps, one built around crime data, the other including socioeconomic data derived from the U.S. Census bureau.
The Clean Sweep maps are some of the most complex GIS visualizations Buffalo uses. Conlee receives data in Excel format from the nine Common Council districts, from the police department, from the 311 system, and from the Mayor's office and community block clubs. He then geocodes the data and uses a spatial analysis module in ESRI's GIS product to create density maps.

The Department for Education is preparing to publish maps pinpointing the neighbourhoods where homes – most of them specialist privately run establishments catering for only one or two children – are located across England.
It illustrates starkly how the homes are heavily concentrated in just two areas of the country, the North West and the West Midlands.
Many children are separated from friends and family by hundreds of miles. The bottom line: location of such homes may be based on real estate prices rather than child welfare.
The Yankton [SD] Community Library, 515 Walnut, will host the “Maps and Apps Science Experiment” on Saturday, Oct. 5, running from 10 a.m.-noon.
Participants will explore how geography and geographic information systems (GIS) help people make smart decisions that improve lives, respect our natural resources and make a positive impact on our world.
I like everything about this: short (2 hours), "science experiment" makes it sounds like hands on is involved, and it's at THE LIBRARY!
