OpenStreetMap: Get FREE Web Mapping with Road Maps for your Apps(pietschsoft.com)

submitted by crpietschmann(11.3k) 2 years, 6 months ago

OpenStreetMap has been around for awhile and provides free geographic data that can be used by anyone. The data is all community created/contributed and that’s why it’s free to use. Other mapping services such as Bing Maps for Enterprise and Google Maps license their geographic data from some other third party and that’s why they cost thousands of dollars per year to use within commercial applications. And, you can use it with JavaScript and Silverlight! read more...

Calculate Distance Between Geocodes in C# and JavaScript (pietschsoft.com)

submitted by crpietschmann(11.3k) 4 years ago

There are times when I need code to calculate the distance between two geocodes (Lat/Long points). I don't need it very often and until now I didn't have a code snippet that I could jus copy and paste. I was searching and found Rob Conery's LINQ and Geocoding post. It's an interesting post and he includes a sample of how to use Lambda expressions in C# 3.0 to calculate the distance between two geocodes in Miles. I decided to copy his code snippet and make sure it works in .NET 2.0 and also convert it to JavaScript. read more...
