Driving your golf cart around Surprise, Arizona is fun until you find yourself on a highway or unable to cross a busy street. Enter the golf cart map, proposed by Councilman Richard Alton to help drivers of these vehicles get around safely. In fact, the map, useful to all, is simply a speed limit map; golf carts are safest on roads with speed limits under 35 mph.
That’s the business model of Charles R. Carpenter who offers up scanned historic cadastral maps of the US on his company site, Historic MapWorks LLC. The pricing, per the site is complex and based on different prices for searching, printing and saving (as jpg or PDF). For now users include genealogists, title researchers, libraries and art galleries but the hope is to license the collection more broadly.
“These developments are so new they are not on any maps. Not even Google.”

The research, done by Cimex, explored how well UK crime maps are serving the public identified obstacles to government goals. The findings suggest “the current crop of crime maps is in fact leaving us more bewildered and confused than before.” (I’ve got an e-mail in asking who funded the study. More on that when I get an answer.)
The problems found:
- Information overload and sites with too many details
- Color coded maps or graphs that did not match
- Overcomplicated navigation & highly inconsistent wording
- Lack of interactivity in maps (whether for area selection or crime rates)
- Insufficient filters for users to narrow down the information
- Unclear time periods or missing points of reference
- Lack of comparison options that put the data into a meaningful context
Suggestions for improvement:
- Maps need to be informative and should be colour coded in a meaningful way.
- Maps and data should be connected to allow users to verify data and build trust.
- Users like to compare and require points of reference such as national averages, neighbouring areas or previous time periods.
- Interactivity enhances the user experience and should help users filter the information according to their preferences.
