Metadata visualization and browse graphics
نویسندگان
چکیده
Metadata that describe characteristics of geographic datasets are used for discovering potential datasets and evaluating their suitability for intended purposes (Guptil 1999, Taylor 2004). Discovery is based on search functions relying on metadata about thematic, spatial, and temporal extents of datasets (Beard and Sharma, 1997) and well developed in directories, clearing houses, and digital libraries. Tools for evaluating datasets by metadata are far less developed. For example, means for comparing closely similar datasets are limited to studying the metadata document of each dataset at a time. By visualization usability of metadata for evaluation could be increased.

A Graph Visualization Tool for Terminology Discovery and Assessment
This paper presents a Graphical User Interface (GUI) mainly based on a graph visualization device and used for exploring and assessing lexical data found in the DiCoInfo, a specialized e-dictionary of computing and the Internet. Computer visualization devices have been used to present and browse data in many fields, but GUIs for electronic dictionaries have not evolved much. Very few take advan...

There are a lot of information embedded in JPEG image than just graphics. Visualization of its metadata would benefit digital forensic investigator to view embedded data including corrupted image where no graphics can be displayed in order to assist in evidence collection for cases such as child pornography or steganography.

متن کاملExploring faceted geo-spatial data with tangible interaction
In this paper we introduce a case study on tangible geo-visualization on an interactive tabletop to enable the exploration of architectural projects in Venice. The tangible user interface consists of a large display showing projects on a map, and a polyhedral object to browse these data interactively by selecting and filtering various metadata facets. With the object we aim to reduce the barrie...
متن کاملSemantic information visualization
In this work we will introduce a system for semantic information visualization and interactive manipulation implemented at CTU Prague. Explicit semantic information is necessary for automatic data processing. Commonly used data formats do not natively include such semantic information. The semantics must be therefore supplied in a separate file. The goal of our system is to enable creation of s...
متن کاملSVG Linearization and Accessibility
The usage of SVG (Scaleable Vector Graphics) creates new possibilities as well as new challenges for the accessibility of Web sites. This paper presents a metadata vocabulary to describe the information content of an SVG file geared towards accessibility. When used with a suitable tool, this metadata description can help in generating a textual (“linear”) version of the content, which can be us...
