Geography ModelingGeographic Modeling: Model Builder modeling and analysis of soil erosion riskUnderstanding the ModelBuilder Operator interface1: Add data or tools from the hard drive into the model, data can also be dragged from ArcMap or arccatalog directly into the model, and the tool can be dragged directly from the Arctoolbox to the model2: Show all model features and fill the Model

. This provides a possibility for the implementation of GIS. According to the actual work needs, the author uses SVG and related technology in Web browser to realize the Web GIS Management System (hereinafter referred to as Webgis), and obtains the very good result. This system includes the design of the server and the client, which is to handle the data storage and the dynamic loading of the data, the clie

How to copy a GIS image to the Windows clipboard and paste it to the word I haven't written this article for a long time. I want to shut down this blog and stop updating it, but I still have no determination. Let's take a look at these days. Let's send a function that was previously written to play.The copy and paste functions are simple, but how can we paste GIS images into word? The simplest idea is to sa

Grid Data uses a regular grid to describe the location and value of spatial symptom features corresponding to the location of each grid unit. In terms of concept, changes in spatial phenomena are reflected by changes in grid unit values. Many data in the geographic information system are expressed in a grid format. Grid Data is complementary to vector data in many aspects. Combining the two types of data is a common feature of GIS projects. I. Element

ESRI shapefile(SHP) is an open space data format developed by ESRI. Currently, this file format has become an open standard in the geographic information software field, indicating the importance of ESRI in the global geographic information system market. I read some documents and was interested in one sentence. "The shapefile file does not contain the topological data structure" [Several other problems arising therefrom] What is topology? What file formats contain topology data structu

Tatukgis announced that it has upgraded the developer kernel Compact framework Mobile GIS Application Development Section, supported by tatukgis dk cf V10 (dk10.cf)Windows MobileAndCEOperating System (including wince, pocketpc, Windows Mobile 5.0/6.x, Windows Embedded handheld 6.x ). This upgrade brings DK. cf to a new level. Although retail applications have gradually replaced traditional mobile operating systems,

This is an interview with a GIS company in Guangzhou last week. First, the resume, the interview, the demonstration of your project, the computer, the two sides, three sides... tired. What do you know about GIS? This is not a good answer. I am confused. I asked Huang Tian. He said that he would give me a better answer in combination with MIS. GIS manages, anal

It turns out that GIS is a geographic information system.ArticleIt is interesting to have a new definition of GIS. share with you: gentlemanlike, intelligence, and smile. The new definition of GIS should actually be the quality that giser should possess: Gentleman demeanor, whether it is to be inclusive, whether it is to people or to academics; wise, it is to ha

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

Label: Ar data 2014 problem working hours as Application Learning This is just my own understanding. I can only talk about GIS and love and hate from my own perspective. I now have a master's degree in one of the most GIS-related schools in Wuhan. I have liked geography since I was in high school. I chose Earth information technology as a major in the university, most of the courses I have studied in th

compression, it has the same performance as the shape file and is stronger than personal geodatabase. When the same data is stored, File geodatabase reduces the disk footprint by 50% to 80% compared to the personal geodatabase.ArcGIS provides tools to extract a file geodatabase from the geodatabase in the DBMS form and to put a file geodatabase in the human DBMS. Users can easily create file Geodatabaee by loading data from any other geodatabase or supported file structure, such as a shape file

terms of style. Udig is easy to use. The advantage is that when the map service is released and you want to modify the style of a layer, you only need to modify the style that was originally referenced, you do not need to re-release the layers. The installation package (ms4w.zip, decompress to the root directory) of mapserverhas built-in Apache. However, because IIS occupies port 80, you need to set the following port (In \ ms4w \ apache \ conf \ httpd. in Conf, change Listen 80 to listen 8081

Because embedded systems and general PC systems differ greatly in computing speed, memory capacity, and storage space, how can GIS engines run well on embedded devices, you need to optimize the following aspects: 1) Data Organization 1. Map Data Compression (curve extraction) There are usually a large number of vertex Vertex on the line and plane data. Because vertex is too dense, it takes too much time to draw. Therefore, map data must be pr

With more information, design and construction tools, remote sensing (suchCAD, Building information model, completion model,LIDARPoint Clouds, etc.) are increasingly used to expand and enrich the application and analysis of geographical spaces. In addition, this integration will expand and accelerate. Like the previousLinuxSame,OsgeoIt indicates that organized and project-Centered Open Source Code behaviors have a huge impact on thousands of geospatial profession

Before reading this article, you should first have an idea to use arcengine to develop C/S applications, A mature GIS project cannot directly organize the data in the SDE in the form of mxd in terms of data loading. This is unscientific for the following reasons: 1. Data security considerations An mxd document contains detailed information about mxd data in the SDE database. Generally, the data owner does not want the information to be obtained fr
