Modest Maps is a BSD-licensed display and interaction library for tile-based maps in Flash (ActionScript 2.0 and ActionScript 3.0) and Python.
Our intent is to provide a minimal, extensible, customizable, and free display library for discriminating designers and developers who want to use interactive maps in their own projects. Modest Maps provides a core set of features in a tight, clean package, with plenty of hooks for additional functionality.
See simple example applications: NASA Blue Marble satellite images, AC Transit Oakland bus lines.

We also have a discussion group,
a roadmap,
subversion, and
a 
news feed for new releases and patches made necessary by occasional updates from
map tile providers. Users of Google Maps tiles should pay special
attention to the news feed, as the road and hybrid map tiles are
subject to frequent changes. If you are writing your own map tiles, you may
find our map transformation calculator and
Zoomifyer tile tutorial useful.
If you are interested in using Modest Maps as a server-side map generation
tool, check out the ws-compose and ws-pinwin tutorial.
What Modest Maps does:
- Displays tile-based maps, from sources such as OpenStreetMap, NASA Blue Marble, Google, Yahoo!, Microsoft, and others.
- Supports developer-defined tile sets in arbitrary geographical projections.
- Smoothly pans and zooms.
- Tracks the position of geographical map markers.
- ActionScript 2.0 codebase works with FlashLite.
Where Modest Maps stops:
- No default display of geographical map markers.
- No default buttons for zooming or panning.
- No support for “local” API’s, such as business searches or white pages look-up.
Modest Maps is a product of Michal Migurski, Tom Carden and Shawn Allen of Stamen Design, Darren David of Stimulant, Aaron Straup Cope, David Knape, and Tomas Apodaca. Project hosting is graciously provided by Mapstraction.
