More sample images, Google Earth and others.
Below are shown some sample images, which indicate the type of images that are desired from the balloon imaging system. These images are from various Mars-like locations on Earth. Google Maps/Earth was used to capture the images.
How much detail will be visible from the balloon will vary significantly based on altitude, weather conditions, topography, type of camera, and speed of the balloon. At moderate altitudes, even a moderate resolution camera should rival orbital cameras and at lower altitudes or with better cameras, very high resolution images should be possible.
