Important remarks about symbology
ArcGIS supports several layer renderers and symbol types. An overview of supported renderers and possible limitations during conversion to Styled Layer Descriptor (SLD) files has being provided. The conversion is optimized for GeoServer supporting some of the SLD extensions that are provided, like dynamic symbolizers and chart renderers.
Although using GeoServer SLD extensions help to provide a high quality rendering, ArcGIS Desktop provides very powerful renderers that not always can be preserved exactly when exporting to SLD. We are working continuously in improve it, but some limitations arise like:
Font symbols: the fonts used in legends of the layers configured in ArcGIS Desktop should be installed in the GeoServer server. This is not always possible due to copyright limitations, for example for ESRI fonts. The SLD engine tries to map some of the ESRI font symbols to Webdings and Wingdings font symbols, but also requires that these fonts are available in the server.
Future releases of Bridge extension are planned to provide a set of open source symbol fonts that can be used both in ArcGIS desktop and GeoServer to improve the rendering of font symbols.
Picture symbol: are not supported now as GeoServer doesn't provide a method to publish the images with the SLD. Next versions of Bridge extension is planned to provide GeoServer custom extensions to support the publishing of images.
