You can often see questions about how to calculate the area and length In ArcMap. In the past, I had a blog post about this. Article It is very clear that it is implemented using VBA. Here we describe the calculation process again. The SHP file of the prefecture-level cities in Guangdong province is used to calculate the area of each prefecture-level city and the length of Multi-deformation, paste the image in the step at the same time. 1. load data

Many users in the process of using ArcMap software, the phenomenon of data loss often occurs. A red exclamation point appears in front of the layer when data is lost! The data display area will have no data displayed. So how to get the lost data back? Small knitting to teach you to solve. 1, select the missing data layer, right key--Properties 2, open the Properties window select Source, click the Set Data Source button to reset the data

This is a summary of my graduation thesis. GIS application in Urban Planning 1) role of GIS in Urban Planning (1) GIS provides intuitive and rational planning tools Commonly used CAD software, such as AutoCAD, usually has strong graphic ability and weak management ability relative to attribute data. Therefore, CAD can only be used as drawing software [30]. Howeve

**GIS电子地图定制开发技术**The definition of "geographic Information System" is made up of two parts. On the one hand, geographic information system (GIS) is a new interdisciplinary subject, which is the theory and method of describing, storing, analyzing and outputting spatial information. On the other hand, geographic information system (GIS) is a technical system, which

After creating a scenario in cityengine, We need to export the created model (in 3DS and OBJ formats ). You can select two export modes: Use File size limit and create one file per shape. Use File Size Limit: export the selected model as an OBJ or 3DS file. Createone file per shape: exports the model according to the shape. A 3DS or OBJ file is generated for the model generated by each shape. Figure 1Export Method Next we will discuss the naming of model files when exporting models using the cr

Use of the editor (point features, line features, digitizing of polygon features)This example mainly introduces how to add coordinate information to topographic map (picture format) without coordinate information. Picture file format with coordinate information has TIFFand gr

The power system is developing towards a high degree of informatization and automation, and the scale of the power grid is expanding. Therefore, it is necessary to manage huge power equipment and facilities data, user data, and planning data. To some extent, scientific decision-making depends on the amount of information held by decision makers. Power generation, substation, and transmission systems are complex systems that contain a large amount of information.

From: Open Source ChinaCommunityForumGeographic Information SystemGeographic Information Systems (GIS) software relies on datasets covering the whole earth. To process a large amount of GIS data and its format, programmers have created several open-source libraries and GIS suites. This article briefly introduces the range and depth of

I. Preface As we all know, two-dimensionalGISWith the rapid development of computer software and hardware and relational databasesGISTechnologies have been improved. It has unparalleled advantages in analyzing geographical information. Some macro geographic information, one-dimensional geographic information, such as rivers and highways, and two-dimensional geographic information, such as vegetation, lakes, and population quantity, in terms of analyzing and processing the geographical informat

Basic IntroductionThe basic geographic information data is stored in Geodatabase (*. mdb). There are two layers: road center line and building.Read each record in the road center layer, generate the corresponding road surface based on the current road width, read each record of the building layer, and generate the correspon

The http://blog.3snews.net/space.php?uid=16796do=blogid=22870 of Jiang waves1984 Turing Award winner, the inventor of the Pascal language, Professor Niklaus Wirth, has given the program a classic definition of "program = algorithm + data structure", sharply. In my opinion, the algorithm and the data structure are like the methodology and epistemology in philosophy, the former clarifies the idea of solving a problem, and the latter provides the object of solving the problem.The term "algorithm" d

of instances of the Transduction service is set to the number of CPU cores +1, because one SOC process is dedicated to recycling and does not participate in the actual work, so this setting can play the maximum performance of the tile server. But in the actual course of operation, we found that this way on some types of servers will cause the SOC process to be created and recycled, and eventually only one process in the transduction situation. At this point we can only find a suitable value by
