If you've ever tried to find a way to display an ESRI ShapeFile on a Virtual Earth map, you'll have probably noticed how little information there is on the Internet about how to accomplish this apparently arduous task. As a matter of fact, I needed to do exactly this while adding some collateral features to the software Serena and I are developing for our thesis, but after some Googling, I found that there was (and there still is) almost no useful information on how to achieve integration between ......
In this article we'll see how easy it is to use Virtual Earth SDK to produce a simple mashup, using web services that provide information in JSON format. Live Demo - Source Code If you are not familiar with JSON or how to integrate JSON services in ASP.NET AJAX applications, you can take a look at my 3-part series of articles on JSON and ASP.NET AJAX here. First of all, we need to create a simple .aspx page, and add a ScriptManager to it. Then, we're going to reference the Virtual Earth API in the ......
This is the third part of a series of articles on ASP.NET AJAX and JSON. If you haven't read part 1 and part 2 of this series, you are strongly advised to do so before going on to read this article. Let's take what we've seen so far on JSON and ASP.NET one step further, and discover how we can leverage the ASP.NET AJAX infastructure to make the managing of an AJAX application even sleeker. Now, let's imagine that we want to elaborate the JSON response returned from the web service before sending ......
Often, when dealing with mathematical models for hazard estimation, one has to make the most out of just a handful of experimental data, and try to extract a rule or a behavioural function. While the use of lookup charts printed on paper may sometimes be a viable option, we won’t be able to rely on it when we want to implement a software solution. When this is the case, soft-computing may look like the perfect solution; neural networks can process data, learn their trend, and elaborate new samples ......
Now, after the very futile example which accompanied the introduction to JavaScript Object Notation in my last post (by the way, I forgot to mention that this is what the fancy acronym stands for, but I'm sure you already knew that), let's go straight to the fun part, and see how we can leverage the flexibility of JSON (and ASP.NET AJAX, of course) to achieve some less trivial result. When developing a web application, we often need to aggregate data from different sources. You might argue this is ......
