Although open source was present and used in the UK before 2006, it was The Guardian newspaper that started a campaign called “Free Our Data,” which called for the raw data collected...

Low-cost DIY GPS Data Logger
It wasn’t that long ago when the ability to create a functioning GPS device was reserved for the big companies, academics, and those with money to burn. Today, thanks to the ever-increasing demand for consumer-grade GPS electronics (such as those in every smart phone), the availability of GPS integrated circuits (chips) has dramatically increased, while...

Crafting The Future via Geodesign
Geodesign is on the move. While the term may be new to some, it is an old concept getting new life via modern technology: how the science of geography should inform our methods of design. In that sense, geodesign is an applied science, and we humans have been doing it naturally since the dawn of...

Morphing Landscapes
Normally we create digital surface models (DSM) and elevation models (DEM) to analyze the topography and visual issues related to a project or issue. The requirement for accuracy and precision is paramount, ensuring that the correct method(s) of converting the data from raw source to an accurate model is more a work of art than...

Open Source
The door to open source geospatial software has been unlocked. It’s time to take a peek inside. The open source geospatial movement is not purely about “free” (as in no cost). There truly are other aspects of “free,” as in “free to develop without constraints,” and free access to public geodata without necessarily having...
