Thus far we have discussed the general workflow for publishing geospatial data using GeoServer, the general concepts relating to styling those data for presentation through the web services published by GeoServer, and specific methods for styling vector data, and applying styles to specific subsets of vector data through the use of filters. This week we conclude our discussion of GeoServer with a demonstration of the methods used in the styling of raster data. Without the application of meaningful styles, raster data can be visually unintelligible. You will learn the tools that you have within the OGC Styled Layer Descriptor standard (as implemented within GeoServer) to define and apply meaningful styles to raster data - ultimately producing more useful visualizations of those data.

This week’s lab will provide an opportunity to experiment with vector layer styling. Please define two custom styles for each of the four vector datasets that you added to GeoServer during last week’s lab assignment. Take a screenshot of the layer preview for each of your styles - including the options tools above the OpenLayers preview displaying the name of the custom style that is being used for the current map display.
Include in your writeup - again submitted as a web page URL - the layer name, the name of the two custom styles and the associated screenshots for each of the four vector datasets.
Add each of the five datasets that you acquired for Homework 3 to GeoServer and style at least three of the layers with a custom style designed to best display the data for your envisioned map. Include in your writeup the names of the datasets, associated styles, and screenshots of the layers in the OpenLayers previewer, with the style name displayed in the OpenLayers preview tool set.
Please submit your writeup as a web page URL.
