        <h1>ArduPilot Terrain Generator</h1>

        <p>Use this to generate terrain to put on your SD card. The generated terrain is based on the SRTM data and has
            100m
            horizontal resolution. It covers all areas between 0 and 60 degrees North/South latitude.</p>

        <p>Multiple generated files can be combined on the SD card.</p>

        <p>Compatible with Ardupilot Plane 4.0.6+ and Copter 4.0.4+</p>
