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

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

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

Recently in doing Unity3d and GIS projects, the most basic is the conversion of coordinates, such as the latitude and longitude (166.23.9.27, 39.55.15.74) into unity into the corresponding location points, nonsense not much to say on the code:usingUnityengine;usingSystem.Collections; Public classSaigetlatlog:monobehaviour { PublicTransform Firstpoint;//top left point in Unity PublicTransform Secondpoint;//bottom right point in Unity Public

applications, I added a layer, that is, the real-time drawing layer, the distance measurement, area measurement, angle measurement and so on the layer, so that the map refreshThe time to redraw the data is not much, improve the performance of the program.First on a diagram, I am currently doing a simple GIS framework (just to meet my current needs, the main feature is fast). As shown in.Initial completion of the above framework design, I got the abov

Service Area Analysis is mainly an analysis concept in commercial site selection. It analyzes the service scope of a mall. In urban planning, it is mostly used for the service scope of public facilities. Besides considering distance and spatial accessibility, there are also the attractiveness and service capabilities of public service facilities, that is, the gravity model is used. In regional planning, we also use the gravity model to consider the distance and the city's own indicators for calc

I just started to study the secondary development of GIS. I recorded several translation methods in the previous article. Today I will look at the functional code of map enlargement. We also look at several different methods when implementing amplification (triggered in the event of the button, and compiled as DLL by using COM technology and registered to the machine ). The first method is compiled into DLL registration.Code Code highlighting produce

In (2), we analyzed the HTML code, and basically figured out how. Net ADF encapsulates client interaction and how the client interacts with the server. Next, let's take a look at the development method on the server side. It is actually a simple practice. If you can learn about the implementation of AGS when developing Web GIS using other jobs, you will surely be inspired by some tips on encapsulating the client, server, and interaction between the tw

and GIS related conferences outside China, numerous and numerous , there are roughly two types. User conferences and technical branches organized by software vendors or organizations, for example, ESRI Annual international / domestic User Conference, developer Conference, special conferences on various technical applications, educational conferences and academic conferences held by universities or associations, for example, 08 ISPR

Label: hbase GIS This chapter describes how to use hbase to store and efficiently query Geographical location information. Geohash spatial index Consider two common problems in the LBS application: 1) find the nearest K locations; 2) Find the locations in a region. If you want to use hbase for efficient search, you must first consider the space locality (spatial locality), that is, the points close to each other must be physically stored together. Th

I have already worked on two GIS projects. due to tight project time and other reasons, it has always been a heap CodeWithout considering the data structure and AlgorithmAnd does not consider the performance. As you can imagine, the last thing is useless. Looking back, I feel like a failure, so impetuous. Just now I have taken over a GIS project. I plan to take this opportunity to develop and summarize i
