Due to work reasons, I have been studying the controls of GIS over the past few days. I mainly read the controls of Supermap and MapInfo. The main achievements are as follows: 1. Most GIS controls have these controls: mapcontrol is used to display maps, zoomin, zoomout, roaming (used to drag a map), moving left, and moving right. 2. I watched some flash and some examples and found that the main functions

1. PrefaceThis week, I did some preliminary exploration of open source software and related technologies and processes involved in the open source solution for GIS, as well as some of the more mature cases that other companies have done with open source solutions. Here I will some technical key points of the preliminary research to do a summary, while the other companies open source success stories to do an analysis, and put forward the personal think

The GIS business development stage is divided: Phase 1: digitalization. At this stage, people are new to GIS. The main business is to digitize previous data;Stage 2: visualization. The user uses spatial data for two-dimensional drawing and three-dimensional roamingCodeConvert to images that are easier to accept and perceive;Stage 3: Spatial statistics, analysis, and Simulation. With the continuous deep u

focus on investment and policy inclination. The discipline construction is intensifying. This subject has a long history. As early as the beginning of 1950s, Professor Lu Shufen, a famous Chinese cartography artist, set up the teaching and research base for cartography. In 1980, Cartography and Remote Sensing became the first master's degree authority approved by the State Council. In recent years, the provincial department of education and schools have attached great importance to the developm

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
