GIS set the foundation for businesses to begin collecting and visualizing geographic information. But in order to stay competitive, businesses know they need to focus on the intelligence from their location data, not just on the geographic information itself.
by Stefano Serafini Everyone remembers the lucky slogan featured by Jane Jacobs in The Death and Life of Great American Cities: for the sake of safety, livability, and hence attractiveness of cities "there must be eyes upon the street". Such a maxim seems to evidently match common sense, but yet some critics have been challenging
After being an open data consumer/visualizer/analyzer/advocate/enthusiast for the past few years, and spending the last two years actually working in the industry (is that a thing? oh my), I've had some time to develop my own open data philosophy. Here are a few tenets with commentary:

HAB (High Altitude Ballooning) is a growing hobby where enthusiasts use standard weather balloons to put small payloads typically 100g-1kg into "near space" at altitudes of around 30km or so, carrying a tracking device (so the balloon position is known throughout the flight) and usually some sensors (temperature, pressure etc) and often a video or stills camera storing to an SD card for later retrieval. The job of the tracker is to read the location from the GPS receiver, possibly also read some sensors, and then format and send a telemetry sentence to the ground over a low power radio link. Flights only happen once the predicted path is known to be safe (avoiding airports and densely populated areas for example) and permission has been gained from (in the UK) the CAA. Here the tracking system uses the 70cm radio band (around 434MHz) using RTTY to send the telemetry down to a number of ground stations run by other enthusiasts. Telemetry from all receivers is sent to a central server that then drives a live map which can be viewed by anyone with an internet connection. The system works extremely well and has been used to track payloads at distances of 800km and more even though the transmitter is limited by UK law to 10mW ERP.
