NewsStand is an example application of a general framework to enable people to search for information using a map query interface, where the information results from monitoring the output of over 10,000 RSS news sources and is available for retrieval within minutes of publication. The advantage of doing so is that a map, coupled with an ability to vary the… (More)
TweetPhoto utilizes a map query interface to display news photos from news articles that are extracted from the tweets of 2,000 Twitter users who have been determined to post news related content. These articles are then geotagged and clustered so that a set of locations are associated with a cluster and its associated images. For each of these locations,… (More)
NewsStand is a Web-based mapping application that we have developed to enable searching for spatially-referenced information by using a map query interface. Previously, we adapted the Web version to execute on mobile devices such as smartphones where the main issue that was confronted was how to deal with the considerably smaller display screen while… (More)
PhotoStand enables the use of a map query interface to retrieve news photos associated with news articles that are in turn associated with the principal locations that they mention collected as a result of monitoring the output of over 10,000 RSS news feeds, made available within minutes of publication, and stored in a PostgreSQL database. The news photos… (More)
The recent introduction of the Apple iPhone 5 and the accompanying iOS6 software environment which, among other changes, replaced the use of the Google Maps API in iOS5 by Apple's own Maps API, has led to significant changes in the user experience with apps that make use of maps and has resulted in closer scrutiny of mapping applications on mobile devices.… (More)
Mobile location-based applications rely heavily on network connections. When the mobile devices are offline, such applications become less accessible to users. A cache-based method is proposed to improve the offline accessibility for mobile location-based applications. The central idea is that when users are browsing information, the client program not only… (More)
Comparing smartphone mapping apps leads to unexpected surprises.
Smartphone mapping apps routinely fail to follow centuries-old mapmaking dynamic consistency principles and practices.
Apple’s introduction of the iPhone 5 and the accompanying iOS6 software environment replaced the use of a mapping App based on Google’s map data with one that makes use of Apple’s map data. It also changed the decisions as to what data is displayed (served to the user) in responses to queries (especially implicit ones through manipulation of the viewing… (More)
Mobile location-based applications rely heavily on network connections. When the mobile devices are offline, such applications become less accessible to users. A semantic cachebased method is proposed to improve the offline accessibility for mobile location-based applications. The central idea is that when users are browsing information, the client program… (More)
