From the website:
This is a prototype to demonstrate how to build a collaborative map with complex content using free services. This could be used for an asset mapping project, a stakeholder analysis, a spatial survey or any other kind of repository that requires specific input (more data fields than a simple description) from many contributors.
With new web applications today we finally have the opportunity to put together a mapping platform that fills this gap: The customizable collaborative map that only requires minimal web-savvy and accounts on three free services. These include Zoho Creator, an online database tool that allows us to build a flexible input type, Yahoo Pipes to map that input and Weebly, for the base website. All these services are free and in combination create a powerful and highly customizable mapping tool like the one you are on. What you see here is easy to replicate and won’t take more than a half hour to set up.
