Автор работы: Пользователь скрыл имя, 28 Марта 2012 в 17:06, курсовая работа

Описание

Основная цель GPS съемки заключается в том , чтобы с высокой точностью определить положение одного приемника относительно другого. В выпускной работе выполнены вычисления для создания геодезической сети применительно к крупномасштабным съемкам. В выпускной работе обосновано использование спутниковых технологий , так как с их помощью можно создать плановые и высотные обоснования для крупномасштабных съемок.
Даны результаты компьютерной обработки, сделано заключение по выпускной работе.
