Maps of UK property prices

Illustreets has released a new Google Map that visualizes house price growth rates in England over the last 10 years. Users can click on each county to examine the growth in house prices from 2004 to 2013. Additional information such as, the total number of houses sold within each period, as well as the number of new houses started are also provided. The primary information for thematic map is derived from Land Registry’s House Price Index data.

This is the second property related map from Illustreets. The first one was a very handy guide to discovering information about local neighbourhoods in England. Topics covered include standard of living, employment and crime rates, asking and sale prices, schools by performance rank, as well as vital statistics about people and dwellings. This is map is one of the best presentations of property related data I have seen so far.

Analysing property price information and presenting results on maps is a topic of a particular interest to me. However, the availability of adequate data for Australia makes it very difficult to explore. used to publish quite a detailed online map in the past but unfortunately, it has been discontinued a few years ago. It is possible to access raw sales statistics for postcodes for a hefty fee but this information is rather inadequate for temporal analysis. For now, Australian property owners and prospective buyers will have to be kept in the dark…

Map of Victorian emergency alerts

The State of Victoria has recently launched VicEmergency, a single all-emergencies website that provides information and advice to help people prepare for, respond to and recover from emergencies. It consolidates information from various state and interstate authorities, including Australian Bureau of Meteorology as well as NSW and SA emergency response agencies.

The list of available data layers is impressive. For example, fire related layers include current fires by alert status, planned burns, satellite detected fires, regions with total fire ban, safe places, and cross border events for SA and NSW.

Available for display are also flood and storm related events, earthquake and tsunami information, weather observations, traffic accidents, hazardous materials and medical emergencies, power outages and more. The developers created a unique set of icons to represent each of those events.

Information can be viewed on a map or as a list. The entire application is built with Google Map API and is optimised for display in mobile devices. Android and iPhone app versions are also available.

Mapping crime in Queensland is a simple Google Map application that allows searching for crimes committed in Queensland by address. The data is sourced from the Queensland Police Service and is presented as a cluster of makers with numbers indicating how many crimes were recorded in the proximity of a given location. Click on the marker opens a detailed list of events by the type of crime, time and date of the offense, as well as whether it has been solved or remains unsolved.

Queensland Police released its own official version of crime map in 2012. It is a fully featured online application enabling analysis of crime statistics for a nominated area of interest, nominated time frame as well as the type of offence. Information can be summarised by the day of the week and hour which is very handy for identifying crime trends.

The application was developed in Silverlight hence, requires a special plug-in to view in other than Internet Explorer browsers.
