Many of you are probably familiar with Feed Validator, a free service that checks to see if your feeds, including KML, are valid, and also makes recommendations based on best practices. Now Galdos Systems has released a new service, KML Validator, specifically for KML. KML Validator gives you a nice simple interface, and helpfully displays relevant portions of the OGC KML spec to explain error messages. They provide two different ways to access their service: upload files for validation, or point to a URL of a file on the web. The site also has a helpful set of FAQs about KML. For those of you who want to check your KML files, and want more than just basic XML Schema validation using the KML Schema, KML Validator offers a nice new choice.
