The FEWS explorer contains a component to show map layers. These map layers are loaded by the FEWS explorer when the FEWS application is started. The location of the map layers is the "\map" directory of the application. This directory contains also a configuration file for the properties of the different map layers and view extent of the map layersAs of the 2007-1 release the maplayers are now put in the Config/MapLayerFiles directory. As such they can now be uploaded with the Config manager and distributed to all the connected clients. When using map layers make sure the files are ArcView Shape files and that the co-ordinate system of the shape files are the same. More on configuring map layers can be found in Appendix C: "Map Component Configuration". For for information on how to configure the MapLayers see the Fews Explorer component documentation.
Parameters
Parameters are stored in the "Parameters" XML file, located in the regional configuration files. Make sure you keep the number of parameters limited to a basic set, the more parameters you use the more complicated the configuration will become. An important property of a parameter or parameter group is the unit. Use the same unit for a parameter group; this can minimise errors in configurations where conversions between time series may introduce errors. Remember that the FEWS can convert units when importing or exporting external time series. More on configuring parameters can be found in paragraph 5.4: "Parameters".
