5000 Crimes in San Francisco

This Google Map displays 5000 crimes in San Francisco almost instantly on a Google Map. The map was created with the Google Maps API and the Dotter.js, a javascript class that generates data URIs.

The crimes displayed were committed in San Francisco between the 25th April and 25th May 2011. What is really impressive about the map is how quickly the 5000 data points load on the map.

If you want to create your own super-fast map with thousands of data points then the Dotter.js class is available on Github

Real-Time Parking on Google Maps

SFpark

The San Francisco Municipal Authority has released a Google Map to help improve car parking in the city. The new map displays real-time information about where parking is available so drivers can quickly find open spaces.

As part of the new initiative San Francisco now periodically adjusts meter pricing to match demand. To help keep car drivers informed about the variable meter prices SFpark displays in real-time current prices.

Roads on the map are color-coded to reflect real-time meter pricing. The darker the shade of green of a road the higher its current pricing. It is also possible to view in real-time the current availability of parking spaces.

City owned parking garages are also displayed on the map. Rates at these garages will now also vary to match real-time demand.

YouTube News on Google Maps

ABC7new's Channel Google Map

The traditional TV and print media are very keen these days to feature videos and photographs of news events captured by the public. The fact that a large proportion of the population now carry mobile phones with built in cameras means that when something newsworthy happens there is a very good chance that some people on the scene will be taking pictures and videos. The traditional media want those eye witness records.

If you look on the websites of the traditional media you will often find a link to submit your photos and videos. In San Francisco ABC7news have gone one better and teamed up with YouTube to create the ABC7 uReport. ABC7 will use YouTube Direct to collect news footage from people in the San Francisco Bay Area.

Residents of the Bay Area are invited to document the news and events happening where they live, work and play, and to submit those videos via YouTube Direct to the producers at ABC7. ABC7 will then feature newsworthy videos on television (Channel 7 in the Bay Area), on their website, and on their YouTube channel.

The YouTube channel for ABC7 news and their website both feature a Google Map displaying the submitted newsworthy videos. The videos are categorised into 'breaking news', 'events', 'weather', 'Bay Area scenes'.

The Best San Francisco Marathon Map Ever

Going the Distance - The Wall Street Journal

The Wall Street Journal have created a Google Map of this Sunday's San Francisco Marathon. The map includes the route, an elevations chart and Street Views of the route.

This in itself would be very impressive but the Walls Street Journal wasn't satisfied so went ahead and mapped the Boston Marathon route, the New York Marathon and the Chicago Marathon as well. Each of them also come with elevation charts and Street View.

My favourite feature of the Wall Street Journals maps is the superb integration between the elevation chart and Street View. If you hover your mouse along the elevation chart the Street View will update to show the respective view. Very cool.

Tracking San Franciscans with Google Maps

Skyhook Experience

Skyhook Wireless have created a Google Map of San Francisco to show where people congregate during different times of the day. The map has been created for this Sunday's San Francisco marathon.

By creating s heat-map of where mobile phone users are located (based on the wifi signals within range) Skyhook are able to give a pretty accurate overview of current hotspots in the city. The map includes a slider that allows you to select different times during the last couple of weeks (up to about two hours before the current time).


Skyhook Wireless have another example from this year's Boston Marathon. The example highlights location lookups along the Boston Marathon route on a Google Map. These lookups are displayed alongside a Google Map showing the previous Monday's activity, demonstrating the increase in human activity in the area due to the marathon.

Mapping the Trees of San Francisco

Urban Forest Map

The Urban Forest Map is a Google Map application that is trying to map every tree in San Francisco.

One aim of the map is to calculate the environmental benefits the trees are providing, how many gallons of stormwater they are helping to filter, how many pounds of air pollutants they are capturing, how many kilowatt-hours of energy they are conserving, and how many tons of carbon dioxide they are removing from the atmosphere.

Using the map it is possible to search for trees near any location in San Francisco. You can find trees that bear edible fruits and nuts or those with beautiful flowers. You can also search the map for trees of a particular type.

Looking at the map you can see that the Urban Forest Map already has a huge database of trees in San Francisco but if you know of one that is missing you can add it to the map.
