SLDs for Visualizing Multicolor Elevation Contour Lines in Geo-Spatial Web Applications
This paper addresses the need for geospatial consumers (either humans or
machines) to visualize multicolored elevation contour poly lines with respect
their different contour intervals and control the visual portrayal of the data
with which they work. The current OpenGIS Web Map Service (WMS) specification
supports the ability for an information provider to specify very basic styling
options by advertising a preset collection of visual portrayals for each
available data set. However, while a WMS currently can provide the user with a
choice of style options, the WMS can only tell the user the name of each style.
It cannot tell the user what portrayal will look like on the map. More
importantly, the user has no way of defining their own styling rules. The
ability for a human or machine client to define these rules requires a styling
language that the client and server can both understand. Defining this
language, called the StyledLayerDescriptor (SLD), is the main focus of this
paper, and it can be used to portray the output of Web Map Servers, Web Feature
Servers and Web Coverage Servers.Comment: 5 page
