Gaia Geospatial Platform. Dracones: Surveillance Tool for Public Health Dracones is a MapServer-based web mapping framework, written in Python, PHP and JavaScript, and DraconesPH is a public health surveillance application that was built using it.
Both are being developed at the McGill Surveillance Lab, and are available as open source. Dracones offers: * A lightweight map widget, with a smooth navigation interface* Map layers with interactive behaviors, like mouse selection or tooltip (mouseover) information* Flexible query/extension mechanism* Handy other services like map image export, and history navigation (undo/redo) The main idea behind Dracones is to provide a set of higher-level MapServer abstractions and services, with which it becomes easier to build complex, interactive mapping applications.
