地形附合导线长度与点位精度的关系
Under the premise of ensuring its accuracy of point positions , not only is vector data obtained but its compressing is also realized with a quicker speed , more accuracy and smaller storage device
该方法在确保点位精度前提下，可获得以弧段为单位的矢量数据，同时依据线状要素的形态取样，从而达到压缩数据目的，此算法处理速度快，精度高、存储量小。
Results showed that , attribute data obtained by this way avoided deficiency of polygon overlap way , as a result , the logistical consistency between map data and attribute data reached over 90 % on average . database pivot precision was 0 . 18mm , data quantity during manipulation was decreased greatly , data treatment was more convenient , computation velocity was boosted greatly . workload of map and table pretreatment and edition was mitigated on large scale , spatial data precision was increase
研究表明：用该方法获得的属性数据，避免了多边形叠加方法的不足之处，能使图形数据和属性数据逻辑一致性平均达到90以上，数据库点位精度达到0 . 18mm ，且操作中图层数据量大大减小，数据处理更为方便，运算速度大为提高；减轻了图表预处理和编辑的工作量，使空间数据精度提高。
We write the program which used for fighting errors in absolute positioning . we also write the program which used for linear combinating in absolute positioning . from analyzing for the measurement of outer , we can conclude that we can use m estimation to estimate parameter in gps absolute positioning . lt has application value . using it , we can obstain the stable positioning result and remove the outer . in this paper , we calculate the data which from the baseline space of the gps calibration space . we also draw some conclusion using broadcast ephemeredes and smoothing pseudoranges . the positionging precision is in 1 - 2 meter
编制了gps绝对定位中抗差估计程序和应用线性组合进行单点定位的程序。通过对粗差量级的分析，得出在gps观测量存在粗差时， m估计是有其应用价值的，它使定位结果较为稳定，减弱和剔除了粗差的影响。应用线性组合程序对gps综合检定场数据基线网点进行计算，得出用广播星历和平滑后的伪距可以给出较好的结果，点位精度在1 ? 2米。
