信息共享：建成体系完整、互联互通的电子政务网络系统和国土资源政务系统共建共享的信息资源库； 　　无缝集成：标准化OA、MIS和GIS的有机集成； 　　B/S结构：实现远程办公办文、远程带图作业，维护简单、安装方便 　　信息发布：通过WEBGIS在互联网上图文并茂的发布土地出让、转让，土地拍卖，土地登记、用地手续、矿产手续等各类信息。 　　二次开发：以平台为基础建立的各类应用，可以方便的进行二次开发，满足业务的各种变化需要。-information sharing : to build a complete system, interoperable e-government network systems and land resources Administrative System Sharing of information resources library; Seamless integration : standardization OA, MIS and the organic integration of GIS; B/S : remote-office run, remote operations with map and maintaining a simple, easy installation information dissemination : WEBGIS on the Internet to browse through the release of land sales and transfers, land auctions, land registration, land clearance, mineral procedures of all types of information. Second development : based platform for a variety of applications, to facilitate the conduct of secondary development to meet the business needs of the changes.

这是在C#+supermap开发平台下的缓冲查询的源代码-This is the C#+ Supermap buffer under development platform source code query

包括部分空间算法，如计算两坐标点距离、判断两坐标点是否相等、计算叉积、计算点积、判断点p是否在线段l上、计算点bp以点op为圆心逆时针旋转dAlpha(单位：弧度)后所在的坐标点位置、计算指定半径圆上指定角度的弦长、计算由起点坐标和终点坐标构成的线段在指定距离和指定方向的垂点坐标等空间算法-Including some space algorithms, such as calculating the distance between the two coordinates to determine whether the same two coordinates to calculate cross product, point multiplication calculation to determine whether point p on line l above the calculation point to point op for bp counterclockwise rotation center dAlpha (units : radian) after the location where the coordinates of points, calculated on the specified radius of a round angle specified chord length, calculated from the starting point coordinates and end coordinates of the line constitutes a specified distance and specified direction of the vertical space coordinate algorithm

用c＋＋读写E00文件，文件的显示动能完全实现，但是属性数据还没能读取成功-Using c read and write E00 document, the document shows the full realization of kinetic energy, but the attribute data can be read not successful

 输入当地时间，当地经纬度（转化为弧度），输出太阳高度（弧度），方向（弧度），计算太阳某个地方某个时刻太阳位置的程序。 此程序算法可以移植到嵌入式设备上，作为太阳能电池板追踪每天太阳方位和高度的算法，提高太阳能板发电效率。 /* 2008年9月3日                                                         */ /* 安志军                                                               */
