作为地籍测量中的基础工作,土地勘测定界为勘界和边界管理提供了基础资源和科学依据。研究了勘测定界的实施流程及勘测定界的成果要求,分析了在清华山维EPS软件中使用模板定制和直接二次开发方法在勘测定界自动化中的利弊,推导了坐标解析法求解不规则多边形地块面积的公式,并使用VBScript开发语言实现了勘测定界图的绘制、界址点和距离的自动标注、宗地面积的自动计算与标注、输出界址点表的功能。结果表明,自动化成图工具优化了清华山维EPS软件使用体验。在有多块宗地的情况下,可以人工指定界址点起始点号,克服了常规软件存在的问题,加快了内业处理流程,提高了工作效率。 相似文献

土地勘测定界是土地征用、划拨、出让、转让中的一项重要的基础工作。精度问题在土地勘测定界中占有十分重要的位置,其精度指标需综合考虑土地的产权管理、产籍管理、产业管理对土地勘测定界精度的具体要求。尤其是随着我国土地使用制度改革的不断深入和地产市场的逐渐发育, 相似文献

以主体功能区规划为基础,划定“三区三线”是编制县级国土空间规划的前提。本文以霞浦县为例,基于资源环境承载能力评价与国土空间开发适宜性评价(以下简称“双评价”),利用GIS技术手段,开展陆海全覆盖“三区三线”的划定。把陆海统筹作为重要原则,通过霞浦县空间规划“三区三线”划定的实践研究,总结问题与不足,为沿海地区开展县级国土空间规划“三区三线”划定工作提供参考与借鉴。 相似文献

The Spatial Data Transfer Standard (SDTS) was approved by the Department of Commerce as Federal Information Processing Standard (FIPS) 173 on July 29, 1992. As a FIPS, the SDTS will serve as the national spatial data transfer mechanism for all federal agencies and will be available for use by state and local governments, the private sector, and research organizations. FIPS 173 will transfer digital spatial data sets between different computer systems, making data sharing practicable. This standard is of significant interest to users and producers of digital spatial data because of the potential for increased access to and sharing of spatial data, the reduction of information loss in data exchange, the elimination of the duplication of data acquisition, and the increase in the quality and integrity of spatial data. The success of FIPS 173 will depend on its acceptance by users of spatial data and by vendors of spatial information systems. Comprehensive workshops are being conducted, and the tools and procedures necessary to support FIPS 173 implementations are being developed. The U.S. Geological Survey, as the FIPS 173 maintenance authority, is committed to involving the spatial data community in various activities to promote acceptance of FIPS 173 and to providing case examples of prototype FIPS 173 implementations. Only by participating in these activities will the members of the spatial data community understand the role and impact of this standard. 相似文献

Abstract While significant progress has been made to implement the Digital Earth vision, current implementation only makes it easy to integrate and share spatial data from distributed sources and has limited capabilities to integrate data and models for simulating social and physical processes. To achieve effectiveness of decision-making using Digital Earth for understanding the Earth and its systems, new infrastructures that provide capabilities of computational simulation are needed. This paper proposed a framework of geospatial semantic web-based interoperable spatial decision support systems (SDSSs) to expand capabilities of the currently implemented infrastructure of Digital Earth. Main technologies applied in the framework such as heterogeneous ontology integration, ontology-based catalog service, and web service composition were introduced. We proposed a partition-refinement algorithm for ontology matching and integration, and an algorithm for web service discovery and composition. The proposed interoperable SDSS enables decision-makers to reuse and integrate geospatial data and geoprocessing resources from heterogeneous sources across the Internet. Based on the proposed framework, a prototype to assist in protective boundary delimitation for Lunan Stone Forest conservation was implemented to demonstrate how ontology-based web services and the services-oriented architecture can contribute to the development of interoperable SDSSs in support of Digital Earth for decision-making. 相似文献

Spatial analysis and spatial information systems have great potential in many non‐geographic domains. This paper presents an example of the utility of spatial analysis in a non‐geographic domain. A technique of pupillometry using digital infrared video loosely coupled with a Spatial Information System and a spreadsheet is developed to accurately quantify pupil dilation magnitude and constriction onset latency for participants of different cognitive ability and under different cognitive loads. Spatio‐temporal pupil dynamics of participants are recorded using digital infrared video. The pupil to iris area ratio is calculated for over 470,000 temporally sequenced de‐interlaced video fields by automatic feature extraction using a combination of threshold analysis, spatial smoothing and areal filtering. Pupil dilation magnitudes and constriction onset latencies are calculated through post‐processing in a spreadsheet. The study identifies inadequacies in current spatial analytical techniques for automatic feature extraction not necessarily evident in geographic applications. Issues impeding the employment of spatial analysis in non‐geographic domains including the lack of a generic spatial referencing system are identified and discussed. 相似文献
