Terug naar eigen land, met een animatie van een rampen scenario, dat nog eens laat zien hoe de kaart behulpzaam kan zijn bij het vergroten van inzicht in allerlei ruimtelijk problemen.
De ontwikkeling van het kartografisch vakgebied, met gebruikmaking van de modernste methoden en technieken is zelf grens verlegend bezig.
framework data and new delivery mechanisms
internet
new distribution channels
new role of maps
new technology and standards
web mapping
map distribution (and teasing)
web mapping tools
xml
uml
gml
svg
xml languages
x = extensible
m = mark-up
l = language
future base-technology for the internet
platform & application independent
tag-based text format
separation of content from presentation
open standard
extensible
SMIL – Synchronized Multimedia Markup Language
MathML – MAthemetical Markup Language
X3D – VRML-successor
SOAP – Simple Object Access Protocol
uml (unified modeling language)
Road Road section Built-up Roads Land use Vegetation object-oriented modelling
Voor het visualiseren van het gegevensmodel is gebruik gemaakt van UML, een taal om een systeem op objectgerichte maniier te ontwerpen en te documenteren
gml (geographic markup language)
xml-based technology for describing and transferring geographic information
abstraction of the real world by means of geographic features
features can have spatial and non-spatial properties
based on the ogc simple features model, geometry model and features can belong to a feature collection
extensible (application schema)
official standards (NEN/CEN): not well supported by products
vendor-specific standards: not fair for competition (other vendors) and may change over time (and may be not be the same on different platforms)
GML is based two important standards: OpenGIS geography model and XML
XML enables well-formed check and valid (according to schema) check
XML documents are text (simple editors)
Integration with non-spatial data (XML-based)
GML/XML is easy to transform (form DLM to DCM) using XSLT
Developed by the OPenGIS Consortium
XML-based open standard
2D Geometrical Features
2D Spatial Reference Systems
XML Schema adoption
3 base schemas for encoding geographic information
Application schema for declaration of custom features
GML is based on the abstract model of the OGC (Simple Features)
World is described in terms of geographic entities called features
Feature definition: „an abstraction of a real world phenomenon; it is a geographic feature if it is associated with a location relative to the earth
svg (scalable vector graphics)
xml for describing two-dimensional graphics
xml-based open standard
vector graphics, text, raster graphics
zoomable
interactivity and animations
transparency
clipping and masking
real-world coordinates support
css and xslt stylesheets
javascript support
Well-documented open ASCII graphics format XMl standard W3C standard for 2D graphics: vector graphics, text, raster graphics
Currently need an SVG browser
