National Geographic has made available free-as-in-beer online USGS topographic maps for everyone to download and print out. Interactively select a region and get five pages of high resolution mapping data. Page 1 is an overview index map. Pages 2-5 are higher resolution quadrants of the index map.
7.5 minute resolution. Sized for 8.5x11 printing so you don't need a huge poster printer.
Requires only an e-mail address to get access.

A Python framework for doing graphical data analysis without needing to know Javascript. Visualizations are updated in realtime as they are interacted with. You'll have to write some code to set it up, it would appear mostly to get the data into the application to begin with.
An Open Streetmap sub-project - this is street-level photography ala Google Streetview.

A Python module which makes it easy to carry out GIS related operations. Look up coordinates of addresses, locations, and landmarks. Has a geocoding function. Can calculate distance between two points on the globe. Pretty straightforward to use.
A site that lets you create map layers on top of Open Streetmap and make them shareable and embeddable. You can upload geodata or sketch in the data you want.

An Open Streetmap effort to build maps of places that are underserved. Humanitarian effort to fill in the blanks where companies don't or won't reach.
A website that mashes up news reports of crime with Google Maps for cities in the United States of America.
A collaborative website which maps wireless access points all across the world using information donated by enterprising wardrivers.
An opensource tool for the visualization of extremely large datasets, like twitter maps or email databases.
A FOSS GIS software package. Create and edit geospatial information on just about every platform. Maybe useful?
A chart and diagram webapp written in HTML5 that lets you do pretty much whatever Lucidchart does. Export to PNG, GIF, and JPEG.
A protocol for encoding geographic locations in a way other than latitude/longitude coordinates. Ideal for places that don't have addresses, like when you're hiking or urbex. 6 or 10 character codes. Crisis response applications. Not case sensitive. Generated from lat/long coordinates. The closer two locations are, the more similar the OLCs are. 10 character codes more accurate than 6 character codes. It's possible to drop characters off the end to encode larger areas. Should be compatible with both Google Maps and Open Streetmaps.

volunteer effort to improve the state of Open Streetmap in places that are generally ignored by other maps because they're too far away, too rural, or otherwise unprivileged or underserved. NGOs and first responders rely on OSM during disasters. They can also rally mappers to develop datasets in specific locations at need (after disasters, usually).
Concerned about the hotel you'll be staying in? Look it up here before making reservations.
An online open and crowdsourced weather service. People set up automatic weather stations (which are fairly cheap) and contribute measurements that are aggregated into forecasts. Has an API so you can pull data out of it as well as contribute it: http://openweathermap.org/appid Free accounts are, of course, limited in several ways. You can also get weather maps of various kinds from the service to visualize the forecast data. Forecast data is in XML, JSON, and HTML formats.
