Converting Raster Images to XML and SVG

Document Analysis and …, 2007

In this paper we describe a new framework based on XML for image characterization, description and storing for fast content-based retrieval. The novelty is mainly in the construction of a unified method for describing images and the related information extracted by means of a generic image processing algorithm. The XML description can be associated to well known image standards or to other cus- tomized application-dependent formats. On this level of image abstraction and description, a method for dynamic querying has been developed, which allows the semantic annotation of the image for a fast retrieval in the database. A prototype of the entire system for image description, storing and retrieval has been developed for GeoTIFF and DIG-35 image formats.

The objective of this paper is to show the way multiple source data like aerial photos, maps and descriptive information are combined and amalgamated to form an Internet or Intranet application. The visual outcome is a large scale, precise and detailed image/map displaying the interiors of buildings in a layered fashion, enabling the user to interact with the objects shown on it. Scalable Vector Graphics SVG is an XML language for the encoding/representation of two dimensional vector data, especially designed for integration with other web standards. SVG provides those basic structures, which are needed for map generation and overcomes the disadvantages inherent to bitmap images displaying spatial data. In the domain of spatial data, SVG constitutes a new powerful standard for visualization and has a great potential along with other XML encoding languages like Geographic Markup Language GML, Extensible Stylesheet Language Transformation – XSLT and Cascading Style Sheets – CSS for th...

This paper discusses how to provide spatial analysis for XML/GML/SVG based WebGIS. In recognition of current XML/GML/SVG based WebGIS's insufficiency of providing spatial analysis, we focus on two important issues. First, based on the theory of spatial data modeling, we propose an SVG-based spatial information representation model to represent the needed spatial data in SVG on the browser side. Furthermore, this paper designs and implements some spatial operators and integrates them into a Spatial Extended SQL (SESQL) to support spatial query and analysis on spatial data which is represented in GML/SVG. This method can greatly improve the functions of current XML/GML/SVG based WebGIS applications, most of which have been only employed for visualization. Finally, this paper designs some case studies. The results of the case study prove that the suggested method is feasible and operable for providing spatial analysis in XML/GML/SVG based WebGIS.

The paper deals with a new technical solution addressed to implement an innovative tools for the sharing data through the web. This new way for the creation of a Web-GIS is based on the SVG (Scalable Vector Graphics), a simple and open web-compliant format, belonging to the XML (eXtensible Markup Language) language-family. This solution allows to access and to share the data in a fast and user-friendly way reducing the time-consuming for the processing and converting data. By means of this application is possible to publish easily GIS applications without giving up the typically functions of GIS software. This "light" solution enables archaeologists (with low computer skills) to perform data-search in a fast and not difficult way without having complex solution on the server-side, neither on client-side.

Most retaining walls and box culverts built for arterial road construction are simple, and the design process of these structures is often repetitive and labor-intensive because they are so similar in structural configuration. Although some integrated design automation systems developed for retaining walls and box culverts have expedited the design process of these structures, the process of collecting and distributing the resultant engineering documents has not been fully integrated with the computer applications. We have been developing a Web-based design automation system to manage the resultant documents as well as to speed up the repetitive design process. Manipulation of engineering drawings in the Web page is one of the critical functions needed for Web-based design automation. eXtensible Markup Language (XML) and XML-based vector graphics are expected to facilitate the representation of engineering drawings in the Web page. In this paper, we present how we used XML and Scalable Vector Graphics (SVG) to compose engineering drawings and represent them in the Web page. XML Data Island we designed to define drawing components turned out effective in manipulating the engineering drawings in the Web page.

This paper shows an approach for converting bitmap images of text glyphs into a vector format which is suitable for being embedded in XML representations of digitized documents. The focus is on a contour based vectorisation method as the output can be easily transformed into SVG glyph descriptions. A concrete implementation is described and the results are discussed with special regard to the visual quality. The work is related to the development of a system for processing documents which are not suitable for current OCR methods. This is especially important in the field of retrospective digitization of historical works.

The explosion of Internet technologies causes an increasing demand for maps on the web. A number of web mapping and cartographic sites include on-line applications that generate maps using server technologies. However, most of the presented maps are of fairly low cartographic quality and very limited interaction. The arising of SVG technology breaks this lack of standardized client-side vector display. For the first time, SVG allows for high quality cartographic elements with interaction and animation, implemented using standardized programming languages and grammars. As the Web has grown in popularity and complexity, users and content providers have demanded more Web sites and visual sophistication. The low-resolution GIFs that populate Web pages today have limited capabilities. SVG is based on Extensible Markup Language (XML), a new standard for creating Web pages that provides the tools needed to go further. This paper describes the way spatial data is stored in an object-oriented environment and subsequently translated, in order to be used for the composition of maps/charts on the Web and open environments. The World Wide Web is fast becoming a standard platform for Geographic Information Systems. Commercial developers are already producing on-line versions of their GIS software. The development of open source software to support this kind of applications remains a challenge that can be tackled with the utilization of XML, which underlies just about all of the current standards for "open" environments.

The img2xml ("image to XML") project plans to develop a 100\u0025 Open Source set of components for the linking and display of manuscript images, transcriptions and annotations. The linking will be based on a Scaleable Vector Graphics (SVG) tracing of the text in the manuscript image, which will then be analyzed and displayed via a web browser interface using tools developed for web-based map viewing. This means that links can be made to and from a graphical representation of the actual text on the page rather than a box drawn around it. The proposed approach will enable linking between text and image in a more fine-grained way than any annotation tool currently in existence. This work represents a fundamentally different way of connecting manuscript images with transcriptions and annotations.

Abstract The monolithic nature of traditional raster images makes controlled dissemination of their internal features a difficult task. Recently, however, XML-based graphics formats such as the Scalable Vector Graphics (SVG) standard are becoming increasingly popular due to their recognized advantages in terms of application interoperability. In this paper we exploit the XML-based data model of SVG to present a model and a syntax aimed at selectively controlling access to graphic information on the Internet.
