Now in addition to graphs, pie charts, and other visual analytics, Qlik Sense users can use CartoDB’s slick Torque animated maps as well as additional visualization renderings. The mortality rates and the space-time patterns of John Snow’s cholera epidemic map. In order to derive the estimated mortality rates for each house location and the space-time pattern of disease spreading, a series of historical documents is consulted from which a set of GIS data is prepared.

These data are subsequently visualised in map forms, and analysed using KDE as well as NetScan [8]. NetScan is a recently developed method for detecting statistically significant concentrations along street networks to render information for interpreting where and when such events have unfolded. A brief description of KDE and NetScan is provided below. Kernel Density Estimation (KDE) KDE is a density estimation method that uses known recorded values to produce a density surface across the study area.

Network-based Scan Statistics (NetScan) NetScan [8] allows us to identify clusters of events at the micro-scale level of street address. Data Despite its popularity, no prior study has investigated the mortality rates or the space-time pattern of the outbreak in Snow’s map. Streets. Using TimeManager for WMS-T layers. This is a guest post by Karolina Alexiou (aka carolinux), Anita’s collaborator on the Time Manager plugin.

Using TimeManager for WMS-T layers

As of version 2.1.5, TimeManager provides some support for stepping through WMS-T layers, a format about which Anita has written in the past. From the official definition, the OpenGIS® Web Map Service Interface Standard (WMS) provides a simple HTTP interface for requesting geo-registered map images from one or more distributed geospatial databases. A WMS request defines the geographic layer(s) and area of interest to be processed. The response to the request is one or more geo-registered map images (returned as JPEG, PNG, etc) that can be displayed in a browser application. QGIS can display those images as a raster layer. We are going to add the following url as the web map provider service: Integration of Temporal and GeoSemantic components into GI and GIS. AMD_IJGIS_cfp.pdf. Analysis of Movement Data.

Hubcab With an ever-increasing trove of real-time urban data streams, we are able to see precisely where, how, and at what times different parts of our cities become stitched together as hubs of mobility.

By using these pervasive, interconnected, and "smart" technologies, we can begin to unravel the complexity of our travel patterns and identify how we can reduce the social and environmental costs embedded in our transportation systems. In HubCab we target taxicab services as a way to understand the linkages between our travel habits and the places we travel to and from most often. Download hi-res video HubCab is an interactive visualization that invites you to explore the ways in which over 170 million taxi trips connect the City of New York in a given year. The HubCab tool expands and changes the perception of urban space using a large-scale data set. International Journal of Spatial, Temporal and Multimedia Information Systems (IJSTMIS.

43816490.2013.pdf. Damien Demaj. Late last year we published an interactive game tree celebrating Rafael Nadal’s historic 2013 season.

The Game Tree allows users to visually explore how easily, or not, Nadal won each of his 666 service games in the Masters 1000 Tournaments, Grand Slams and World Tour Finals he played in 2013. This rare point-by-point summary shows where Nadal’s history breaking season was won and rarely lost. Figure 1. Nadal’s Interactive Game Tree was released after the completion of the World Tour Finals, November, 2013. Click here to view the application. How the Project Began… The idea for the project came about after years of frustration by never really knowing how close a match was by just looking at the final score. _paper_preprint.pdf. Nanocubes: Fast Visualization of Large Spatiotemporal Datasets. iGeolise lets you measure distance by time rather than as the crow flies.

The next time you're looking for a place to buy or rent, will you choose it by the distance from where you work – or by the time it takes you to get to work by bus, train, tube or car?

iGeolise lets you measure distance by time rather than as the crow flies

Most people actually want to choose by the latter. Now a British company called iGeolise is promising to commercialise that idea for all modes of transport – and expand it from the UK to Europe and the US. Since this summer it has already helped TalkTalk decide where it ought to relocate its offices to – when it was considering moving a thousand employees – and a major high street store is considering offering it on its site to help web searchers find their nearest outlet, measured by time rather than the usual distance as the crow flies.

The market for such a service is growing: rival Mapumental offers time-based maps for travel on public transport. "I would think those three would find it useful," says Peter Lilley, who co-founded the company along with Charlie Davis. Exploring Mobility Data Using Time Manager. Plot your course in space & time.
