DEM Based on Contour Line Generation Algorithm and Implementation
nandQueryAlgorithmofBus-routeInformationSystemBasedonPDATongWeiping, CaiXianhua, XuLizhen (TransformationInstituteofSouth-eastUniversity, NanJingJiangSu210008; ComputerScienceEngineeringDepartmentofSouth-eastUniversity, NanJingJiangSu210008) AbstractInthispaper, abus-routeinformationsystembasedonPDAisdesigned.

KeyWordsPDA,ghd glätteisen, Mobiledatabase, Queryalgorithm, GPS, LocationBasedService (on the next page 35) points outside the region to determine whether the method is: if ever there is a vertical alternative point of vertical or horizontal rays, the ray intersection with the regional demand,uggs outlet rotterdam, if intersection is an even number or zero (assuming that the intersection is not located adjacent to the region constitute the intersection of line segments) are alternative points outside the region, or in the region. For the fault line, according to data collected by DEM major shift position did not constitute treatment and to determine a network region. When the P value is positive when in the AB on the left, when the value is negative on the right, when in the same line is 0.5 Conclusion We introduce the contour-based method of generating DEM and contour lines described in detail discrete points,UGG ブーツ, the characteristics of Delaunay triangulation, TIN, and the establishment of a problem solution to a wide range of products for today's application of DEM a shallow exploration and practice.
