What Is GIS Cartography?

GIS technology (Geographic Information Systems) is a cross-disciplinary product. It is based on geographic space and uses geographic model analysis methods to provide a variety of spatial and dynamic geographic information in real time. Computer technology systems for geographic decision services. Its basic function is to convert tabular data (whether it comes from a database, spreadsheet file or directly entered in the program) into a geographic graphic display, and then browse, manipulate and analyze the displayed results. The display range can be from intercontinental maps to very detailed block maps. Realistic objects include population, sales, transportation routes and other content.

GIS technology

Geographic Information System (GIS) technology is a spatial information analysis technology developed rapidly in recent years. It plays a leading role in the field of resources and environmental applications. GIS technology can not only effectively manage a variety of resources and environmental information with spatial attributes, perform rapid and repetitive analysis and testing of resource and environmental management and practice models, facilitate decision-making, and evaluate scientific and policy standards. Dynamic monitoring, analysis and comparison of resources and environmental conditions and changes in production activities during the period, data collection,

While GIS technology has made progress in the field of environmental resources, it is undeniable that there are still many problems in the application of GIS, mainly reflected in:

Data sources and data quality are difficult to guarantee (the data sources are extensive, but the data quality is not high). Resource and environmental issues involve soil science,

GIS is closely related to several other information systems, but it is distinguished from them because of its ability to process and analyze geographic data. Although there are no hard and fast rules to classify these information systems, the following discussion can help distinguish between GIS and desktop mapping, computer-aided design CAD, remote sensing, DBMS, and GPS technologies.

GIS technology desktop mapping

Desktop mapping systems use maps to organize data and user interaction. The main purpose of this system is to produce maps: maps are databases. Most desktop mapping systems have only limited data management, spatial analysis, and personalization capabilities. Desktop mapping systems operate on desktop computers, such as PCs, Macintosh, and small UNIX workstations.

CAD GIS Technology CAD

Computer-aided design (CAD) systems facilitate the design and planning of building and capital construction. This design requires the assembly of inherently characteristic components to produce the entire structure. These systems need some rules to indicate how to assemble these parts and have very limited analytical capabilities. CAD systems have been extended to support map design, but tools for managing and analyzing large geodatabases are limited.

GPS GIS technology remote sensing and GPS

Remote sensing is the science and technology of using sensors to measure the earth, such as cameras on airplanes, global positioning system (GPS) receivers, or other devices. These sensors collect data in the form of images and provide specialized functions for using, analyzing, and visualizing these images. Because it lacks powerful geographic data management and analysis functions, it cannot be called a true GIS.

DBMS GIS technology DBMS

Database Management System (DBMS)

Database management systems specialize in how to store and manage all types of data, including geographic data. DBMS optimizes storage and lookup data, and many GIS rely on it for this purpose. Compared to GIS, they have no tools for analysis and visualization.
