OpenPilot is a next-generation Open Source UAV autopilot created by the OpenPilot Community (an all volunteer non-profit community). It is a highly capable platform for multirotors, helicopters, fixed wing aircraft, and other vehicles . It has been designed from the ground up by a community of passionate developers from around the globe, with its core design principles being quality, safety, and ease of use. Simplicity does not come with any compromises either: with no hard-coded settings, a complete flight plan scripting language and other powerful features, OpenPilot is an extremely capable UAV autopilot platform. There are two platform for this : The OpenPilot CopterControl Platform – a single board self-stabilizing controller for planes, quads and helicopters. The CopterControl & CC3D boards are an all-in-one stabilization hardware which runs the OpenPilot firmware. It can fly any airframe from fixed wing to an octocopter and is configured and monitored using the OpenPilot Ground Control Station (GCS) software. The OpenPilot Revolution board, also called ‘Revo’, is a new breed of Autopilot using the STM32F4 Micro-controller. This is important as it contains a hardware floating point unit (FPU), which is a huge advancement for hobby-class autopilots. Of course, OpenPilot has been 32bit since day one, and the FPU is another step up the performance ladder. Firmware : RELEASE - 15.02.01 - (Hotfix update for v15.02 - 04/05/2015) - Revo, CC3D, Atom, CC and v9 GPS https://wiki.openpilot.org/display/WIKI/OpenPilot+Downloads Available in Windows , OSX and Debian Linux official source : https://www.openpilot.org

Urban Network Analysis: A Toolbox for ArcGIS 10 / 10.1 The City Form Lab has released a state-of-the-art toolbox for urban network analysis. As the first of its kind, this ArcGIS toolbox can be used to compute five types of graph analysis measures on spatial networks: Reach; Gravity; Betweenness; Closeness; and Straightness. http://vimeo.com/44728530 The tools incorporate three important features that make them particularly suited for spatial analysis on urban street networks. First, they can account for both geometry and topology in the input networks, using either metric distance (e.g. Meters) or topological distance (e.g. Turns) as impedance factors in the analysis. Second, unlike previous software tools that operate with two network elements (nodes and edges), the UNA tools include a third network element - buildings - which are used as the spatial units of analysis for all measures. Two neighboring buildings on the same street segments can therefore obtain different accessibility results. And third, the UNA tools optionally allow buildings to be weighted according to their particular characteristics - more voluminous, more populated, or otherwise more important buildings can be specified to have a proportionately stronger effect on the analysis outcomes, yielding more accurate and reliable results to any of the specified measures. The tools are aimed at urban designers, architects, planners, geographers, and spatial analysts who are interested in studying the spatial configurations of cities, and their related social, economic, and environmental processes. The toolbox is built for easy scaling - it is equally suited for small-scale, detailed network analysis of dense urban areas as it is for sparser large-scale regional networks. The toolbox requires ArcGIS 10 software with an ArcGIS Network Analyst Extension.
