With the development and application of information technology, the digitization of information management and the virtualization of physical models have become very important technical application fields in the world. The establishment of the 3D landscape model and the realization of the 3D geographic information system (GIS) are based on this, and there is not only a wide range of development prospects in many aspects such as urban planning and management, planning and design, local government construction, housing industry development, land monitoring and management, and environmental monitoring and evaluation. There are not only research studies and formulations but also a practical significance in other analysis, evaluation, decision making, and other departments. In recent years, the research of 3D city modeling has been developed rapidly, and most of the existing 2D-GIS can be transformed into 3D visual landscape. Based on the three-dimensional geographic information system and desktop drawing software AutoCAD, this paper takes the two-dimensional line drawing (DLG) of a residential district as the base map, expounds the design process of the three-dimensional simulation model of the urban community from the aspects of map preprocessing, building simulation model construction, texture mapping, and virtual visualization, and discusses the problems encountered in it. The main contributions of this paper are that this technology puts forward a new solution for the integrated corridor operation and maintenance management, greatly improves the intelligent management level of the integrated corridor operation and maintenance work, and simplifies the complex integrated corridor operation and maintenance management. It is helpful to improve the work efficiency of operation and maintenance, reduce the dependence of personnel, and respond to the long-term construction needs of the smart city at the same time.

Traditional urban planning is generally expressed in a two-dimensional geographic information system, but its performance is limited to the plane direction. It cannot give people more natural feelings and visionary experiences. The rapid development of three-dimensional geographic information systems brings people geographic information. The three-dimensional intuitive experience, but the traditional three-dimensional geographic information system has the disadvantages that the spatial properties are incompatible, the image rendering speed is slow, and the visualization effect is poor. In this paper, the traditional domain-oriented processing method is improved in spatial data processing and modeling. An optimized object-oriented optimization algorithm is proposed. The three-dimensional geographic information is optimized based on a dynamic multiresolution model and multilevel detail processing technology. The rendering of the system enhances the visualization. Based on the optimization algorithm of data processing and visualization technology proposed in this paper, the spatial data processing platform GISdata of 3D GIS is designed in this paper. At the same time, the 3D GIS is visualized based on OpenGL visualization software. It is shown that the optimization algorithm proposed in this paper has excellent preexperimental effects.

<p><strong>Abstract.</strong> Management of spatial data by means of Geographic Information System (GIS) plays an essential role based on the latest achievements in Geomatics domain. Geomatics offers the possibility to share, compare, and exchange data between researcher and users in unambiguous and accessible ways for map production and user-friendly technologies for results communication.<br> Although sometimes the geodesist’s contribution to certain projects for landslide monitoring meant to develop early-warning-systems or risk maps is not adequately appreciated and he is only seen as supplier of measured geometric data, the geodesist has a significant contribution through his abilities regarding the modelling of dynamic systems, like strategic constructions (dams, tall buildings etc.) or landslides and data processing and interpretation.<br> This study focuses on using geomorphological characteristics to detect the changes and the effects of landsliding using the ArcGIS 10.1 extension, Geostatistical Analyst.<br> One of the main uses of geostatistics is to predict values of a sampled variable over the whole area of interest, which is referred to as spatial prediction or spatial interpolation.<br> The extension allows creating a surface from data measurements occurring over an area where collecting information for every possible location would be impossible and gives us the possibility to fully understand the qualitative and quantitative aspects of the data.<br> By providing us with the opportunity to predict and model spatial phenomena based on statistics and incorporating powerful exploration tools, ArcGIS Geostatistical Analyst effectively bridges the gap between geostatistics and geographic information system (GIS) analysis.</p>

With the digital development of city construction, the construction of three-dimensional Geographic Information System plays an important role for the urban construction planning and decision-making. 3D urban planning geographic information management systems need to be able to put different spatial data, information of urban construction, urban planning information into the same platform. The integration of information resources whick provids a variety of spatial information based on the intelligent application services is the core. This article puts urban planning geographic information management related to business needs in-depth analysis, and put forward a three-dimensional geographic information model which is used for integrated management of data and can be dynamically adjusted for urban planning and management of business processes.

This article focuses on the study of the ceiling of the corridor of the Dolmen of Cubillejo de Lara, Burgos, Spain. The process of computerisation has contributed to a better comprehension of what may or may not have been possible for its original architecture. During the study, previously lost information regarding petroglyphs within the corridor was recovered, which has been very important in understanding the structural solution of this structure in the past. This has been the fruit of interdisciplinary work, where the diagnosis of the state of the stone has played a fundamental role, assisted by techniques such as orthophotogrammetry, three-dimensional (3D) modelling and geographic information system (GIS), to recognise how the process of degradation has shaped the current condition of the corridor as part of the construction, in such a way as to be capable to reconstruct its possible original form through its current state. The result has been contrasted with other concurrent dolmens existent in the area, which has confirmed the validity of virtual reconstructions to confront hypotheses sustained for decades without further evidence to back them.
