Transit Maps FREE 1.0.3

Transit Maps is a navigation app that lets you download, save, and view large-size maps in PDF and image formats. The map viewer supports image sizes of several thousand pixels in each direction, with pinch zoom and drag scrolling.

It comes with built-in unofficial maps for the New York City subway and Philadelphia rail system, but you can delete them and add your own maps.

Download maps, schedules, and any other PDF or image files from the Internet. Use the built-in web browser to choose and download your map image. This app will save the images so that you can later access them when you dont have network access, for example in a subway tunnel.

To delete or reorder the maps list, tap on the Edit button in the list. To rename a map, click on the blue disclosure button on the right side of the list.

Single-finger double-tap to zoom in up to 200%, two-finger double-tap to zoom out, or use the two-finger pinch to zoom in and out.
