From this data bare earth digital terrain models (DTMs) can be processed semi-automatically, then draped with aerial imagery. Although both the resulting DTMs and geo-referenced aerial photography are of increasing detail and availability, buildings and similar structures are difficult to automatically extract at a level of detail that provides a credible sense of presence at street level. The LiDAR data itself is currently not captured often or extensively enough or at a sufficient level of detail that it could be relied on to keep VR analogues of real places up to date through an automated process alone, without additional modelling. Significant costs in modelling and updating urban settings to convey presence thus remain, be it through a combination of photogrammetry, CAD drawings and manual editing. It is argued that these costs are likely to limit large area 3D modelling to either broad brush overviews (as provided by Google Earth) or to credible presence models in those few locations where the high cost is justifiable, but in which, once the primary purpose of the model has been served, acceptance of the continuing cost of maintenance to reflect change is unlikely. Where updating of high presence models does happen this paper puts forward the view that currently, due to cost, it is likely to be piecemeal and take place over a long period of time. The paper describes one approach to reducing these costs by empowering heterogeneous groups of people to share the tasks of digitising and updating buildings that convey a credible sense of presence","PeriodicalId":222118,"journal":{"name":"Tenth International Conference on Information Visualisation (IV'06)","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122078160","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Such interaction allows the user to explore the visualization, to interactively select a subset of points and see how these changes are updated in other related views. Traditionally, the artefacts that are 'brushed' are the plotted elements in the visualization (e.g. the points on a scatter-plot, or the bars of a bar chart). In this paper, we discuss the concept of ubiquitous brushing (UB), which brings together various different types of selection (whether in data space, screen space or views). Not only can users brush over elements in the display but also they can brush over various meta-information such as menus, legends or axis to affect the highlighted elements.

Texture possesses multiple principal perceptual channels, which makes it good at encoding multiple data attributes contained in weather data. The natural textures existed in the real world especially provide plenty of choices to encode the data with visually pleasing images. A controllable texture synthesis method is developed to generate a large amount of textures which change the appearances of their individual perceptual dimensions according to the underlying distribution of data attributes. In order to encode more data attributes we further propose multi-layer texture synthesis. The background and foreground textures are separately synthesized and then combined together for display.

Currently this reduction is achieved by using schematic mapping techniques. With the advent of high-end miniature technology as well as digital geographic data products like OSMasterMap and OSCAR, it is essential to devise proper methodologies for map generalization specifically tailored for MobileGIS applications. This paper is concerned with the problem of producing schematic maps suitable for rendering on mobile display devices (e.g. PDAs). The application of schematic mapping can be thought of as a data reduction technique for large scale datasets to make it suitable for rendering in mobile applications. These techniques have been based on computation and have not incorporated any understanding of how the simplification affects the ease of use of the maps. It is therefore desirable to devise suitable generalization techniques incorporating human factors considerations for generating schematic maps from large scale datasets for display on small display devices to be used for MobileGIS applications","PeriodicalId":222118,"journal":{"name":"Tenth International Conference on Information Visualisation (IV'06)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117073595","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
