After v2.4 last fall, MapGuide Open Source 2.5 has been released. Can anyone share thoughts or links regarding MapGuide's user community? Is it still vibrant as it used to be?
Major new items from the release notes: "
Via Google I learned about OpenSignal, which provides a cellular signal coverage map.
From their about page: "With your help, we're creating a comprehensive database of cell phone towers, cell phone signal strength readings, and Wi-Fi access points around the world. Our goal is to become the global authority on wireless networks. On this website we provide visualizations and analysis based on the data we've collected, including cellular coverage maps that show exactly how strong signal is in any particular area, as well as all the nearby towers for your carrier. [...] In return for users submitting their signal strength data, we pledge to generate a coverage map and make it available for anyone around the world to view, for free, at any time!"

From NASA: "Turning on new satellite instruments is like opening new eyes. This week, the Landsat Data Continuity Mission (LDCM) released its first images of Earth, collected at 1:40 p.m. EDT on March 18. [...] LDCM sees eleven bands within the electromagnetic spectrum, the range of wavelengths of light. OLI collects light reflected from Earth's surface in nine of these bands. Wavelengths on the shorter side include the visible blue, green, and red bands. Wavelengths on the longer side include the near infrared and shortwave infrared. LDCM's second instrument, the Thermal Infrared Sensor (TIRS) detects light emitted from the surface in two even longer wavelengths called the thermal infrared. [...] LDCM's normal operations are scheduled to begin in late May when the instruments have been calibrated and the spacecraft has been fully checked out."
The open source java desktop GIS uDig released its version 1.4. uDig also officially joined LocationTech recently (here's our previous entry on LocationTech).

The race for improved indoor navigation goes on, MacRumors informs us that Apple Acquires Indoor Mobile Location Positioning Firm WifiSLAM.
From the Wall Street Journal: "The two-year-old startup has developed ways for mobile apps to detect a phone user’s location in a building using Wi-Fi signals. It has been offering the technology to application developers for indoor mapping and new types of retail and social networking apps. The company has a handful of employees, and its co-founders include former Google software engineering intern Joseph Huang. [...] Google already offers indoor mapping in certain locations like airports, shopping centers and sports venues."
