This work presents a web-based application with the capability of creating and editing georeferenced boundary maps (polygons) of geographical areas using georeferenced images. The application is platform-independent. It can run on any computer with a compatible browser and an Internet connection. The application provides the capability of locally storing boundary maps attaching spatial information from the images that facilitates image searching. The boundaries can be imported from other sources and they can also be exported to make them available for other GIS applications. A usability study conducted with the application demonstrated that it is easy to learn and to use. The participants of the study were able to complete 96% of the task with just a fifteen minutes tutorial. I addition they found all the interaction actions tested to be easy to use.
