The project entailed the construction of a land use database for the Public Administration of “Borgo Val di Taro” in northern Italy. The task was accomplished by integrating the existing data provided...
“Metadata Portal for Maps” that is named as “Map Information Bank” is intended to be established by General Directorate of Land Registry and Cadastre (GDLRC). The aim is to Monitor Map Production in T...
X-band UniScan and L-band Alice-SC ground stations manufactured by R&D Center ScanEx have several important features.
This study presents the results referring to the analysis of QuickBird high resolution satellite images to establish patterns associated to the landscape dynamics in bamboo forests at the Intervales P...
Land is a basic resource for wealth creation, and on it activities of man take place. Efficient information on land is a good foundation for wealth generation and national development. Land valuation ...
The paper gives the following results of our study in the filed of the 3S technology application in the large scale land utilization map updating. ①The compound technology of graphics and images bases...
It is well known that the commonly used separable extensions of one-dimensional transforms, such as the wavelet transform, have limitations in capturing the geometry of image edges. But natural scene ...
In Malaysia, the cadastre system is controlled by two main agencies, namely, Department of Surveying and Mapping Malaysia (DSMM) and Land Offices (L.O). The DSMM is responsible for the cadastral spati...
A main advantage of terrestrial laser scanning is the possibility to nearly simultaneously acquire the geometrical positions of millions of object points in 3D. However this is also the main bottle ne...
针对拓扑检查算法复杂、计算量大,串行计算已远不能满足海量地籍数据高效拓扑检查需求的问题,在分析了点线拓扑关系的并行特点基础上,将界址点的数据划分方法与界址线的Q&R空间索引方法相结合,实现了界址点与界址线的并行拓扑计算。用某地区实际的界址点集与界址线集对点线拓扑并行检查进行实验。测试结果表明:并行检查算法的并行效率随着进程数的增加而有所衰减,但稳定在30%以上,加速比达到5以上,且相比于ArcGI...
将地籍地块间空间拓扑关系的判断分为2个层次来处理:2个简单地块间空间拓扑关系的判断;1个简单地块与1个复合地块间空间拓扑关系的判断。2个简单地块间空间拓扑关系的判断可直接利用Oracle Spatial提供的空间关系查询操作算子来实现;复合地块和简单地块间空间拓扑关系的判断,按照双四元交模型(D4I)的思想,将其转化为2组简单地块,然后利用Oracle Spatial的空间关系查询操作算子来处理。...
1995年5月在柏林召开了国际测量师联合会,与会专家对地籍给予了高度重视,为了满足建立和维护地籍的需要,通过了关于地籍的声明,声明中提出了诸如法律、组织和技术方面的一些观点,现将其提纲掣领地介绍如下测绘信息
数字化地籍是城市地理信息系统的基础,地籍图是城市各专题图的基础图。地籍调查(权属调查与地籍测量)的数据质量至关重要。本文对以实现多用途为目标的数字地籍数据的类型与特征及数据的质量特性进行了分析,结合日常宗地图的测绘的质量控制体系的探讨及建立对技术设计、作业生产与产品检查等三个环节的控制体系。
探计了村庄地籍测量的三种方法,重点发析了边长勘丈法在溧水县村庄地籍测量的可行性,通过实践对比,分析了该方法对测量成果的精度影响.
地籍测量是指土地权属调查的基础上,利用测量仪器,采用科学的方法,在调查区域内,建立地籍控制网,测量每宗地的地籍要素的过程.通过权属调查和地籍测量,形成各种数据库,就可以建立规范的地籍信息系统.结合工作实践,谈谈变更测量与地籍信息系统维护的关系.
