| Abstract: | Based on the typical Field data,the paper evaluates the working precision of 1PJ-2500 laser leveling machine.The paper was analyzing in three points: Elevation standard deviation,measurement points Elevation distribution,and 3-dimensional landforms map of the plots surface.The result shows that high-precision land leveling effect could got in using 1PJ-2500 laser precision leveling machine,the average elevation standard deviation achieve at 1.54cm,96.77% measurement points of plots surface were in Range of ED<3cm.The farmland surface roughness and Elevation distribution have substantial improvement. |
| Keywords: | laser leveling machine precision land leveling precision of farmland surface leveling three-dimensional topographic map |
