Abstract

V originále

Paper is focused on usage SVG as multimedia format for creation of electronic thematic maps. We already use SVG format for publishing vector on WWW, by this way we use SVG only such graphic format which is easy generate by CGI scripts. In this paper we would like to describe our experience with SVG such complete environment, client side or non-web , for electronic map design. Possibility of internal scripting enable possibility to use SVG such data storage, visualization tool and simple geoprocessing. Of course this role cannot play SVG self but in collaboration with appropriate interpreter supporting SVG DOM and with another standard www tools such like a JavaScript. We will focused on thematic mapping, exactly of choropleth map design issues. Key point which we solved are implementation of cartographic zoom (scale driven map face, it means automated and semi generalization of visualized features), variable text placement (different text density with alternative based on on-focus text boxes), map face driven legend, floating and rotatable map face, displaying of additional attributes in table and graph form and attaching multimedia features with on-focus appearance. Special attention will devoted to variable color management of map face (scale or theme driven with possibility of limited user control). Also cartometric issues and statistics of map feature are discussed. Beside cartographic issues we would like to describe creation of controls in SVG and possibility for user interaction.

Článek je zaměřen na využití SVG jako multimediálního formátu pro tvorbu tématických map v elektronickém prostředí. SVG formát je využíván pro publikování vektorových dat na WWW, neboť je snadné ho generovat prostřednictvím CGI scriptů. Vnitřní scriptování nám umožní použít SVG pro ukládání dat, jako vizualizační nástroj a také pro jednoduchý geoprocessing. Jde nám zejména na prověření možností zapracování kartografického zoomu, umisťování textů, managementu barev atd.
