US: The City of Buffalo in New York has developed a map to spot the crime and property violation data in its neighbourhoods. Just six months of statistics and socioeconomic data has been used to create maps that can pinpoint neighbourhoods with maximum issues.
The 311 system (Call and Resolution Center) in Buffalo gets about 300,000 calls a year. GIS specialists in Buffalo’s MIS department found that limiting the data set to six months gave the best picture of the city”s issues. They then created two maps, one built around crime data, the other including socioeconomic data derived from the US Census bureau. They received data in Excel format from the nine Common Council districts. This included data from the police department and the Mayor”s office also. GIS specialists then geocoded the data and used a spatial analysis module from Esri to create density maps. These maps can show where poverty, crime and 311 calls overlap, pinpointing neighbourhoods with special needs.
