Vogels mentioned four types of architectures making use of Spot: map-reduce, data grid software, queues, and check point restore software.

Vogels提到使用实时定价的四种架构：map-reduce、数据网格软件、队列以及检查点恢复软件。

A triangulated irregular network(TIN) is constructed based on vector data, and DEM point-array data is computed by interpolating grid on TIN.

并基于等高线矢量数据建立不规则三角网，再内插格网生成DEM点阵数据。

We have achieved the parallelization by extracting the analysis boxes and model grid point latitude rows with leaped step and distributing data to different processors.

该算法通过间隔选取分析盒子和模式格点纬圈行，将数据分配给不同的处理机实现分布式并行。

The grid index based on linear quadtree is used to index the point cloud data, extracting the point cloud on the block.

采用基于线性四叉树的格网索引对点云数据建立索引，对点云数据进行分块提取；

Terrain data is organized by grid, the article adopts height weighted average algorithm of elevation based on grid network, to extract feature point of TIN terrain.

采用网格索引来组织地形数据，利用反距离高程加权平均值算法，提取TIN地形的特征点。

After the point cloud data were compartmentalized to be grid and stratifying plane was set off, boundary points were found in every stratifying plane and these points were drafted by B-spline curve.

将点云网格化，确定分层平面，在每个分层平面上求出边界点集，并区分出分别属于型腔和岛屿的边界点，利用B样条曲线拟合技术进行光顺处理。
