栅格数据模型
Examples
- Employing raster data model for data processing and integration , and
在资料处理和集成中采用栅格资料模型； - In the raster data model , the map s accuracy also depends on the map s scale
在栅格数据模型中，地图的准确性还依赖于地图的比例。 - The distribution gis data management methods and its application in distribution running are systematically researched , which compose distribution gis network topology analysis ( nta ) and optimal rush - maintain path ( orp ) , and distribution planning , which composes distribution spatial load forecasting ( slf ) : ( 1 ) with systematic analysis on the relationship between spatial data model and spatial data structure , the distribution feature and the two common gis data models are analyzed , which are vector and raster data models . then the conceptual and logic data models of distribution gis are designed . the spatial data storage structure is given by using vector method , and their detailed data management methods are proposed
（ 4 ）将gis的空间信息分析功能应用于配网空间负荷预测（ saptialloadforecasting ， slf ）的研究：综合利用灰色理论及遗传规划的优点，提出了一种根据馈线的历史峰值负荷进行外推的组合slf法：首先采用负荷转移耦合法来修正负荷历史，消除由于负荷转移引起的误差；然后根据实际馈线路径和配网gis图形分层，运用图层叠加分析得到馈线的实际供电范围；接着采用灰色关联度聚类方法对馈线负荷增长曲线进行聚类分析；最后采用遗传规划来对灰色聚类结果进行符号回归，分别得到每一类曲线的最佳拟合曲线形式。 - This paper supplies systematic research on data organization method which is suitable for hngis , at the same time studies deeply on the optimization of transit route with many goals in highway network . ( 1 ) based on the systematic analysis on the spatial data model and the spatial data structure , through study on two kinds of commonly used gis data models : raster data model , vector data model and the characteristics of highway network , the paper plans the logistic data model of hngis , and proposed the spatial data storing structure based on vector method
本文系统的研究了适合于公路网gis的数据组织方法，同时，对公路网多目标最优出行路径问题也给予了深入的研究： ( 1 )通过对两种常用的gis数据模型(矢量数据模型、栅格数据模型)及对公路网络特征的分析，设计了公路网gis的逻辑数据模型，给出了基于矢量方法的空间数据存储结构。
