AutoLevel, GPS Land Grading, allows growers to maintain their own fields and waterways for drainage and flood irrigation. It eliminates the need for costly surveyors by automatically recording field elevation at higher resolution than traditional 100-foot stakes. It then calculates "best-fit" slopes and generates cut/fill sheets and contour maps. AutoLevel provides growers with a precision tool for highly effective water management. AutoLevel continuously monitors global GPS reference points and adjusts the scraper blade height relative to the desired grade.
