???? Using GIS technology for cartographic mapping, the ultimate goal is to return to the cartography. The following are some of the classic requirements for map making in cartography:Maps must conform to reality, to human perception.???? This is the most basic of the map, each element of the map is shown with the actual entity corresponding, although sometimes in order to highlight the characteristics of the geographical features and moderate exagger

Self-accomplishment of GIS mapping staff (2)--Cartographic consciousness by Li Yuanxiang The last mention of some cartographic errors of GIS mapping personnel, mainly for the GIS cartographic staff to analyze some of the problems in the cartographic work. But how to improve the self-cultivation of cartography, but it is a very long process, this chapter mainly fo

Application of design patterns in GIS I. Overview of design patterns With the wide application of object-oriented technology, software reuse has been adopted in more and more development projects. In the process of studying software reuse, the concept of design pattern was proposed. The so-called design pattern is a summary of some experiences in Designing object-oriented software. Its appearance can be said to be an important milestone in the develop

1. Curiosity First, GIS professionals should be curious. This curiosity is not just about geospatial technology, but about the world around us. In our work, we must actively consider the spatial relationship of phenomena, ranging from local to global, covering population, land use, transportation models, regional natural disasters, biodiversity, and global climate change. The number of new multimedia, sensors, and mass data sources has increased s
