Objective ========= Style the maps to look as close as possible to the familiar topo map sheets in the following context: 1. all styles to be defined in OGC SLD (Styled Layer Descriptor) 1. in most cases SLD / SE v 1.1. portal.opengeospatial.org 2. in some cases SLD v 1.0, where GeoServer has not implemented a 1.1 element. portal.opengeospatial.org 3. Use GeoServer extensions (CQL filters, geometry transformations, etc) and VendorOptions where SLD is lacking. 2. custom graphics in SVG or png formats 3. conform to NGI published specifications where avai …
