• Maple is an open source ARM based board designed by Leaflabs and is an easy to use platform just like the arduino. Maple is a board based on the STM32F103RBmicroprocessor. The Maple runs at a maximum of 72 MHz, has 39 digital input/output pins, 16 analog inputs, native full speed USB, 3 USARTs (hardware serial ports), integrated SPI/I2C support, a power jack, and a reset button. Maple is programmable over USB via our provided DFU boot loader, no extra hardware required! Users can also program the onboard program flash via external JTAG interface. Maple offers security support for read/write protected addresses, as well as User and Handler processor modes. It has a real-time sysTick, useful for a real time OS or any timing sensitive applications. 6 advanced interrupt timers will help you here as well. Maple can be powered via USB, a wall adapter, or it can run off of a rechargeable lipo battery (see below for more info).

  • SQLCipher is an open source SQLite encryption extension. It provides transparent, full database, AES -256 encryption with minimal performance impact. SQLCipher works by encrypting database pages before they are written to storage and decrypts them on read so encryption functionality is completely separate from the application.
    SQLCipher uses good security practices including CBC mode, randomized initialization vectors, and PBKDF2 key derivation with a unique database salt. SQLCipher depends on the trusted and peer-reviewed OpenSSL project for cryptographic functions. SQLCipher is cross platform and has been used successfully on the iPhone, Mac OS X, Linux, and Windows

  • Commonly referred to as GRASS, this is free Geographic Information System (GIS) software used for geospatial data management and analysis, image processing, graphics/maps production, spatial modeling, and visualization. GRASS is currently used in academic and commercial settings around the world, as well as by many governmental agencies and environmental consulting companies. GRASS is an official project of the Open Source Geospatial Foundation.

  • The Integrated Data Viewer (IDV) from Unidata is a Java(TM)-based software framework for analyzing and visualizing geoscience data. The IDV brings together the ability to display and work with satellite imagery, gridded data, surface observations, balloon soundings, NWS WSR-88D Level II and Level III radar data, and NOAA National Profiler Network data, all within a unified interface
