Why is my KML or KMZ file not displaying on the map?

The Rock Cloud allows you to upload a kml or kmz file into your project, but there are limits!

Maximum file size (KML or KMZ):

3MB

Maximum number of network links:
10

Maximum number of total document-wide features:

1,000

Number of KML layers:

There is a limit on the number of KML Layers that can be displayed on a single Google Map. If you exceed this limit, none of your layers will appear on the map, and an error will be reported in your web browser's JavaScript console. The limit is based on a combination of the number of KmlLayer classes created and the total length of all the URLs used to create those layers. Each new KmlLayer you create will take up a portion of the limit for the layer and a further portion of the limit depending on the length of the URL where the KML file was loaded from. Consequently, the number of layers you can add will vary by application; on average, you should be able to load between 10 and 20 layers without hitting the limit. If you still hit the limit, use a URL shortener to shorten the KML URLs. Alternatively, create a single KML file consisting of NetworkLinks to the individual KML URLs.
