Chartographer Visually Dissects Map Stylesheets
Kelsey Taylor, writing on the Stamen blog:
Chartographer [is] a visualization tool that breaks down different stylesheet properties by layer and zoom level for easy analysis and debugging. Now instead of panning and zooming around the map to find and identify issues, or scrolling through thousands of lines of JSON looking for mismatched zoom numbers, you can visualize how layers are styled at all zoom levels in a single view.
Chartographer looks like a handy tool if you’re hand-crafting map stylesheets.
