There is a confluence within 49 miles (79 km) of you if you're on the surface of Earth. We've discounted confluences in the oceans and some near the poles, but there are still 10,198 to be found. You're invited to help by photographing any one of these places. Read the Information pages, and contact us if you have questions.

One of the most important current trends in the high-tech industry is the rise of spatial and location-based technologies. Once the exclusive domain of complex GIS systems, these technologies are now increasingly available in small applications, websites, and enterprises. This document provides a brief overview of the concepts, techniques, and tools for implementing location-aware application features, focusing on the Ruby programming language and an open-source technology stack.

We make it easy for developers to create location-aware applications.
