目前非测绘专业RS和GIS的实习在教学内容和教学组织上存在前后割裂的缺陷,具体表现为RS采集数据后,缺少进一步深入的空间分析和知识挖掘过程;而GIS操作的数据源现势性差,大多采用已经示例数据,既导致了数据资源的浪费,又使学生缺少对空间信息项目总体流程的把握。本文厘清了这两门课程的逻辑关系,提出了将这两门课程实习合并为空间数据采集和分析综合实习的思路,以解决城乡规划科学问题为目标,以项目实战过程为主线,对实习内容进行了一体化设计。即采用面向对象法对高分辨率遥感影像进行了解译,其成果作为GIS数据源;然后通过空间分析计算城市规划指标,并进行了建筑日照分析。在湖南农业大学城规专业进行了实践检验,结果表明,空间数据采集与分析实习包括空间数据的采集、空间数据建库和空间分析,逻辑清晰、可操作性强,提升了学生综合动手能力,实习效果较好,可为其他高校和专业的空间信息相关课程实习的教学改革提供可借鉴的思路和方案。
At present, the internship of non-surveying and mapping professional RS and GIS has some shortcomings in the teaching content and teaching organization. For example, lack of further in-depth spatial analysis and knowledge-mining process after RS data collection; Most of the examples already use data not only led to the waste of data resources, but also to make students lack of overall grasp of the spatial information project process. This paper clarifies the logical relationship between these two courses and puts forward the idea of combining the two course internships into the spatial data acquisition and analysis of integrated practice to solve the scientific problems of urban and rural planning as the main line of the project actual combat process, Conducted an integrated design. That is, the object-oriented method is used to interpret the high-resolution remote sensing images and the result is used as the GIS data source. Then the urban planning index is calculated through spatial analysis and the building sunshine analysis is carried out. The results showed that the spatial data acquisition and analysis internship includes the collection of spatial data, the establishment of spatial data database and spatial analysis, which has clear logic and strong operability, which enhances students’ comprehensive practical ability, Internship effect is better, for other colleges and professional teaching of spatial information related courses teaching reform can provide ideas and programs.
