GIS基础软件技术体系发展及展望 总被引：1，自引：0，他引：1
地理信息系统作为IT系统的重要组成部分,其技术的每一次进步都与最新IT技术的兴起息息相关。随着云计算、大数据、人工智能等技术的发展与应用,如今GIS基础软件已经形成五大技术体系：大数据GIS技术体系,增加了对空间大数据的存储管理、分析处理以及可视化的能力,丰富了空间数据的内涵;人工智能GIS技术体系,GIS通过结合人工智能相关算法,增强了GIS模型的分析预测能力,同时二者之间相互赋能,在增强GIS能力的同时,也让人工智能具备空间分析和可视化能力,拓展了其应用范围;新一代三维GIS技术体系,实现了二三维GIS一体化和多源异构数据的融合,推动了三维GIS从室外走向室内,从宏观走向微观;分布式GIS技术体系,突破了数据类型和容量的限制,数量级提升了GIS软件的性能,让高可用和高可信GIS应用成为可能;跨平台GIS技术体系,使得GIS软件可运行于不同类型的CPU架构和操作系统,满足日益丰富的多终端应用需求。五大技术相辅相成,进一步拓展了GIS基础软件的能力和应用场景。本文以SuperMap GIS为例,详细介绍了GIS五大技术体系的具体内容,阐述了每项技术的难点与创新点,并用光环曲线对五大技术体系的发展阶段进行了划分,探讨了未来GIS技术的发展趋势。 相似文献

作为人工智能的代表性技术,深度学习已经成为大数据等各个领域中最具有突破性发展的新技术。深度学习的成功主要得益于其新颖的数据驱动的特征表示学习能力,这种能力成功地替代了传统建模中基于领域知识人为设计特征的方式。在这些技术推动下,人工智能技术在新一代GIS基础软件技术的研究与应用中发挥着极为重要的作用,而现有人工智能GIS（AI GIS）技术研究整体仍处于初步探索阶段,距离成熟阶段尚有较大距离。作为新一代GIS基础软件的方法和技术,AI GIS已经广泛应用在遥感数据分析、水资源研究、空间流行病学和环境健康等地学领域,与传统GIS模型相比大大提高了对非结构化的遥感或街景影像和文本的地理信息提取和特征理解能力,显示出巨大的价值和发展潜力,但现有研究对AI GIS软件技术体系的梳理和总结尚不够全面。大部分研究只关注地理空间人工智能算法的研究及其特定场景下的应用研究,而对相关的AI GIS软件技术体系关注较少。本文分析了地理智慧的几个层次,并讨论了其与AI GIS的关系,总体介绍了国内外现有人工智能技术与GIS软件相结合的发展现状,进而提出了AI GIS软件技术体系。根据AI与GIS的结合关系提出了AI GIS由地理空间智能算法、AI赋能GIS和GIS赋能AI三部分组成。此外,为深入介绍AI GIS各部分组成,本文以SuperMap为例,探讨了AI GIS软件的设计与实现。最后,探讨了AI GIS的未来发展中亟需解决的问题。本文基于AI GIS软件技术的初步探索,尝试为地理智能的基础GIS软件技术体系的构建提供理论基础,以促进人工智能技术与GIS技术的进一步融合和发展,为实现地理智能提供一个可行的研究方向。 相似文献

现代社会大型复杂建设工程越来越多,室内3D GIS应用需求旺盛,但海量室内3D数据的缺乏成为室内GIS应用瓶颈。建筑信息模型(Building Information Models,BIM)提供丰富的建筑空间几何和语义信息,可为GIS所用。BIM与GIS数据集成技术成为国内外研究热点。本文从GIS应用的角度出发,通过分析BIM与GIS在数据标准和几何、语义表达方面的差异,提出BIM与SuperMap GIS 8C软件的数据集成技术,并实现了BIM在SuperMap GIS中的高性能空间分析与可视化。本文的研究有助于扩展SuperMap GIS的应用领域至室内空间,实现室外到室内、城市宏观到建筑微观的一体化应用,满足大型复杂室内场所的应急救援、导航与位置服务需求,服务于智慧城市建设。 相似文献

The ability of cell to modulate the fluidity of plasma membrane was crucial to the survival of microorganism at low temperature. Plasma membrane proteins, fatty acids and carotenoids profiles of Antarctic psychrophilc yeast Rhodotorula sp. NJ298 were investigated at -3 ℃, 0 ℃ and 8 ℃. The results showed that plasma membrane protein content was greater at -3 ℃ than that at 8 ℃, and a unique membrane polypeptide composition with an apparent molecular mass of 94.7 kDa was newly synthesized with SDS-PAGE analysis; GC analysis showed that the main changes of fatty acids were the percentage of unsaturated fatty acids (C18∶ 1 and C18∶ 2) and shorter chain saturated fatty acid (C10∶ 0) increased along with the decrease of the culture temperature from 8 ℃ to -3 ℃; HPLC analysis indicated that astaxanthin was the major functional carotenoids of the plasma membrane, percentage of which increased from 54.6±1.5% at 8 ℃ to 81.9±2.1% at -3 ℃. However the fluidity of plasma membrane which was determined by measuring fluorescence anisotropy was similar at -3 ℃, 0 ℃ and 8 ℃. Hence these changes in plasma membrane's characteristics were involved in the cellular cold-adaptation by which NJ298 could maintain normal plasma membrane fluidity at near-freezing temperature. 相似文献

As an important component of the cryosphere,sea ice is very sensitive to the climate change.The study of the sea ice physics needs accurate sea ice thickness.This paper presents an electromagnetic-induction(EM) technique which can be used to measure the sea ice thickness distribution efficiently,and the successful application in Bothnian Bay.Based on the electromagnetic field theory and the electrical properties of sea ice and seawater,EM technique can detect the distance between the instrument and the ice/water interface accurately,than the sea ice thickness is obtained.Contrastive analysis of the apparent conductivity data obtained by EM and the value of drill-hole at same positions allows a construction of a transformable formula of the apparent conductivity to sea ice thickness.The verification of the sea ice thickness calculated by this formula indicates that EM technique is able to get reliable sea ice thickness with average relative error of only 12%.The statistic of all ice thickness profiles shows that the level ice distribution in Bothnian Bay was 0.4-0.6 m. 相似文献

Based on the hydrographic data in austral summer during the 22nd Antarctic Expedition of China(2005/2006),some features can be found about the northern margin of Emery ice shelf as follows.The heat content in the surface layer(0-50 m) at the eastern end and the western end of the ice-shelf margin is much higher than that at the middle.The upper mixing-layer depth and the seasonal thermocline depth at the middle of the ice-shelf northern margin are much shallower than those at the both ends.However there is much less difference between the middle and the ends in the bottom layer.The remote sensing photos show that the inhomogeneity in the surface-layer water is closely related to the spatial distribution of the floes and polynia in the area. 相似文献
