In this Silverlight-based project, we demonstrate the best practices for rendering and querying data that resides on the server or the client. The Map Suite Silverlight Edition provides the developer with many different options on where and how to render your map data. This sample renders one shapefile(airports) on the client side and another shapefile(counties) on the server side. Querying the client-side airport data is very simple and the coding is very similar to the desktop, WPF or WebEditions. Querying the server-side county data is a little more involved and requires the client to communicate back to the server side using a WCF service. This sample presents the developer with a ready to use sample that demonstrates both methods.
You can also check outPart 1 and Part 2 of the video which provides a brief summary of this sample.

In today’s Web project, we learn how to extend ScaleBarAdornmentLayer to create a custom scale bar that is based on a projection of choice instead of the projection of the map. This can be useful when the displayed projection of the map has highly distortable distances especially at high latitudes such as Spherical Mercator (used by Google Map, Virtual Earth, Yahoo maps etc). Using a scale bar based on distance geometry of the Geodetic (WGS84) projection will give a more accurate result. Note that the CustomScaleBar class is based on MapSuiteCore and can be used in any other versions of MapSuite such as Desktop.

This sample shows how you can suppress and draw exceptions in desktop overlays instead of throwing them. There is a little-known feature in the Map Suite Desktop Edition Overlay class that allows you to draw an exception in the event an exception is thrown during the drawing process. We have a default image we draw in this case; however, you can override this using the DrawExceptionCore method and draw whatever you want. By default we always throw expections, but to start drawing them you can use the Overlay.DrawExceptionMode property.
This week, we decided to publish in the Code Community the project for Map Suite Explorer. You are already familiar with that free Desktop tool that comes with any edition of Map Suite. It is a basic GIS tool that allows you to view your geographic data and its tabular information. It also allows doing some basic manipulation on your date such as building the spatial index. With the source code at your disposition, you can cut time developing your own application by having at your disposal the code for doing common tasks such as loading, unloading layers, building spatial index, changing styles etc. You will also find interesting the legend and see how you can add, remove, move up and down the different layers. It is by far the most comprehensive project in the Code Community to that date. You will need the reference for MapSuiteDesktop.dll and MapSuiteCore.dll (full or evaluation) to run it.
