“…A time slider is used to scroll through temporal data across time. With respect to previous versions, the new interface includes, among other features, the following items: map generation tools, to allow users to better specify and export a map; two user profiles: Bthematic^(general public) and Bdo-ityourself^(advanced users); improved interactivity, using innovative mapping techniques (Gaffuri 2012); temporal visualisation, to display animated maps and graphics with a time dimension.…”

The European Atlas of the Seas offers a snapshot of environmental and socio-economic features that characterize the coastal and marine environment. The latest release (Version 4) addresses the public in general, but also nonspecialist experts involved with environmental issues, human activities or policies related to Europe's coasts and seas. The information content of the Atlas comprises a series of geographical layers, subdivided in Bbackground maps^, Bthematic maps^(i.e. maritime Europe, natural setting, sea bottom, sea level rise, security, transport, tourism, energy, wind, fisheries and fish consumption) and Bdo-it-yourself maps^(dealing with marine knowledge, nature and environ-

This article introduces interactive video maps for the web. The main component of video maps is a video stream that is areally georeferenced to a spatial reference system in the same way rectified raster orthoimages are georeferenced. The areal georeference allows for interactivity that goes beyond the play, pause, and stop functionality of video player software. We highlight two types of functionality, allowing the user to (1) combine the video stream layer with other raster and vector map layers and (2) adjust the projection of the map in real time. We exemplify video maps by A Year in the Life of Earth's CO 2 , an interactive video map that visualizes the results of a high-resolution NASA computer model of global atmospheric carbon dioxide distribution. The map shows how carbon dioxide travels around the globe over the course of one year. We use a combination of WebGL, a programming interface to the hardware-accelerated graphics pipeline, and HTML5 video for adding an areally georeferenced video layer to other map layers, and for the on the fly projection of the video stream in the web browser.ARTICLE HISTORY

“…Raster tiles dominated the earlier years of map tiling (especially for mobile clients), mainly because of its simplicity and the limited computation capacities on the mobile client [15]. However, as mobile users' demand for a more interactive and informative mapping service growth [16], vector tiles have come to light recently: vector tiles provide readable, descriptive, and extensible content, which facilitates the provision of data supplementation, manipulation, and customization.…”

Mobile applications based on geospatial data are nowadays extensively used to support people's daily activities. Despite the potential overlap among nearby users' geospatial data demands, it has not been feasible to share geospatial data with peer wireless devices directly. To address this issue, we designed a scheme based on vector tiles to organize spatial data and proposed a system named GeoTile for geospatial data caching and sharing. In GeoTile, a tile request from the mobile client relies on multihop communication over intermediate nodes to reach the server. Since GeoTile enables all network nodes to cache and process geospatial data tiles, requests may be handled before they actually reach the server. We implement the GeoTile prototype system and conduct comprehensive real-world experiments to evaluate the performance. e result shows that the GeoTile system can serve vector tiles for users conveniently and friendly. In addition, the caching mechanism based on vector tiles can substantially reduce the response time and network throughput under the wireless multihop scenarios.
