Simplify SOE Deployment with Self Registration

Registering SOE’s can be a pain, but there is an easier way.

Esri suggests having a separate exe that registers the dll, but this needs to be done after running Regasm on it.

On top of that, if you’re running Win7, and right click on a .bat file and choose to “run as Administrator”, the current working directory does not get set to the folder where the .bat is located. What a pain.

Instead of building an SOE as a dll, build it as an exe. The Main program of the SOE can do the registration/unregistration. First, by calling Regasm, and then by registering with AGS, similar to Esri’s sample.

I haven’t tested this a lot in production, so if you run into issues, please let me know.

I’ve posted a sample solution here that illustrates this.


Network Trace Add-in for ArcGIS Silverlight Viewer

network trace add-in

Today, without any coding, I created this web mapping app that performs network tracing. (Edit: to activate the trace toolbar, click the far right button on the main toolbar).

OK, I lie. I did spend a bit of time coding over the past couple of weeks, but the resulting tools: an Add-in for the ArcGIS Silverlight Viewer, and a Network Trace Server Object Extension can be re-used easily in three steps – without writing any code.

1) create an mxd that references one or more geometric networks, set the projection on the dataframe to web mercator. The network I used was downloaded as a file geodatabase from the National Hydrography Dataset.

2) publish the mxd as a map service, configuring it to use the Network Trace SOE.

3) using the Builder, create a viewer app that includes the mapservice and the Network Trace tool, configured to point to the mapservice.

If you’ve used Arcmap’s Utility Network Analyst toolbar, you may find this add-in tool familiar.

For more information on the Builder, see Esri’s Silverlight/WPF blog post.

Indoor GIS with Wp7

Professor Mike Goodchild says

the average American only spends 13 percent of the time outdoors. GIS-based services help us find restaurants and hotels, but they offer almost no support for navigating in the complex indoor spaces of shopping centers, hospitals, mines, or airports.

I still get disoriented at the Dev summit. I’d like to be able to see a floor plan map of the conference center, oriented to north centered on my location. It seems like the WiFi routers could be used for in door geolocation. However I don’t see anything in Wp7 that would estimate my location based on relative strengths of nearby wifi routers.
