手持GPS在土地执法外业核查中的应用

土地执法外业核查中使用手持GPS,能够快速、准确定位,有效地提升工作效能。根据多年工作经验,以枣庄市台儿庄区154号图斑外业核查流程为例,介绍手持GPS在土地执法外业核查中的应用。认为手持GPS具有快速、准确的定位功能,可以保证土地执法检查的时效性和准确性。但目前手持GPS在土地执法检查的应用刚刚起步,还有很大的潜能,其PDA功能还有待挖掘。     

应用车载移动测量技术进行大比例尺测图的方法

结合车载移动测量技术特点和测区实际情况,对外业扫描和内业数据处理过程进行了研究,并详细阐述了利用点云和影像数据进行大比例尺地形图制作与检查的方法,最后与传统测图方法进行了比较。结果表明,车载移动测量技术可以满足1：1000地形图测绘的精度要求,而且地形图制作效率较传统方法提高数倍。本文的研究可以为今后车载移动测量技术在大比例尺地形图测绘中的应用提供参考。

Expression of strain and rotation tensor in geodetic coordinates

In this paper, unit moving trihedron is first constructed for a point on the surface of a revolution ellipsoid. Via translation, the origin of the trihedron coincides with that of Cartesian coordinates established at the center of the ellipsoid, and then through two coordinate rotations, the trihedron completely coincides with the Cartesian coordi-nates. Transformation formulae between the moving trihedron and unit Cartesian coordinate frameworks as well as transformation of point displacement between two unit coordinate frameworks are presented. Based on the above transformation formulae between two different coordinate frameworks, due to the fact that the displacement and moving trihedron of the point are both functions of the geodetic coordinates, components in the corresponding axis for differential of displacement vector and geodetic curves arc differential at the point in geodetic system can be obtained through complicated derivation. Displacement gradient matrix at the point in geodetic system is also given. Finally, expressions of strain and rotation tensor in geodetic coordinates are presented. Geometric meanings of the rotation tensor are explained in detail. The intrinsic relationship between strain tensors of sphere and ellip-soid are also discussed.
