KML Editors
I was needing to create some KML files recently so had a quick hunt around for easy ways of creating and editing them. And whilst I could obviously do this in Google Earth itself, I already had a list of co-ordinates that I simply wanted to convert. And, of course, if it’s simple and straightforward that makes life much easier. I quick hunt around found CSV2KML which is freeware and allows the conversion of a CSV file to KML (doh!). The nice thing with this is that any spreadsheet (or indeed text editor) can very simply create a CSV file. It’s a nice solution and very simple to implement.
If you want to start from scratch with detailed control over the KML file and how placemarks are viewed then Northgates KML Editor is a good option. Again it’s free and easy to use.
