information representation

Based on an overall analysis of the methodology and technique for the description of terrain information representation, the TCI ( Terrain Complexity Index), a new concept and quantification method for terrain complexity is proposed.

在充分阐述各种地形信息表达方式的基础上，提出了基于栅格DEM的地形复杂度指数的概念与计算方法。

The actual fusion process can take place at different levels ( pixel-level, feature-level and decision-level) of information representation.

图像融合处理能够在信息表征的不同层次上进行，一般将多传感器图像融合由低到高分为三个层次，即像素级融合、特征级融合和决策级融合。

Agricultural resources have the characteristics of the space distribution and spatial correlation etc. Make use of the functions of three-dimensional GIS multidimensional information representation, processing and analysis etc provides strong support for agricultural resources management and decision.

农业资源具有空间分布、空间相关性等特点，利用三维GIS的多维信息表达、处理和分析等功能，可为农业资源管理与决策提供强有力的支持。
