Trail Charts 
March 2012
Trail Charts is a mapping API which can be used on your website to display a large number of separate KML feeds (trails) on a map. A speadsheet is the main data source, containing one row per trail.
Any number of additional columns (fields) can be contained in the speadsheet. Template functions allow you to easily customize how these fields are displayed within the map.
Two maps are used, the first map displays the overall area and the second map displays the currently selected trail. Menus and submenus can filter your trails by category or by date.
A tutorial, examples and an API reference are provided.
• Open Source Mapping API.
• Ideal for travel mapping.
• Display a collection of KML trails.
• Organize trails by category/subcategory or by date.
