Geographic Information Systems (GIS) are an increasingly important component of business, healthcare, security, government, trade, media, transportation and tourism industries and operations in China. GIS software is playing an increasing role in the way Chinese companies analyze and manage business operations.

Geographic information systems (GIS) first became widely available in the 1980s and 1990s, when the only source of geographic data for China was paper maps. Several universities undertook the task of digitizing this information so researchers could use it.
The two earliest projects were conducted by The Australian Consortium for the Asian Spatial Information and Analysis Network (ACASIAN) at Griffith University and the China Data Center at the University of Michigan at Ann Arbor. ACASIAN specialized in spatial coverage while the China Data Center included GIS coverage in their mission to provide Chinese statistical and census data.
High-quality GIS data is produced in China by both government organizations and private companies. China's National Spatial Data Infrastructure Project uses the WGS84 standard. The partial timeline is:

In the early 1980s, China began studies for the establishment of its Geographic Names Information System (地名信息系统) and Geographic Names Information System Research Laboratory, and the establishment of the National Atlas of Geographical Names database research.
The China Association for Geographic Information System (simplified Chinese :中国地理信息产业协会; traditional Chinese :中國地理信息產業協會; pinyin :zhōng guó dì lǐ xìn xī chǎn yè xié huì), Peking University and other institutes sponsored the first "Innovation and Development, 2006 College GIS Forum" in Beijing. More than 300 experts attended the forum. Sessions involved China's GIS research in multi-disciplinary fields, personnel training, and technology. China has now more than 500 institutions of higher learning training GIS-related professionals, of which more than 200 universities and colleges have established a GIS lab. [1]

The GIS industry in China is worth 400 billion yuan per annum as of November 2007. More than 300,000 people were involved in either building or using these systems, according to Zondy Cyber Group president Wu Xincai, who is also the president of the China Association for Geographic Information System. Almost 20,000 enterprises are estimated to have engaged in the industry. The biggest vendor of GIS in China is Zondy Cyber Group, followed by SuperMap. Around 2,000 of these have GIS as a core discipline or function. The industry's rapid expansion is attributed to China's economic development, which has led to an increase in capital input, from both government and businesses. Between 2001 and 2005, the Ministry of Information Industry allocated more than 20 million yuan to fund the development and application of GIS. GIS has been used in land survey, mineral exploitation, water conservancy and environmental protection. It also has applications in power generation, mapping, telecommunication, and the management of public administration and public services.
Chen Shupeng (1920–2008) [2] is considered the founder of remote sensing and GIS in China. [3] Chen started the State Key Laboratory of Resources and Environmental Information System (LREIS) in 1987. [4]

A geographic information system (GIS) consists of integrated computer hardware and software that store, manage, analyze, edit, output, and visualize geographic data. Much of this often happens within a spatial database; however, this is not essential to meet the definition of a GIS. In a broader sense, one may consider such a system also to include human users and support staff, procedures and workflows, the body of knowledge of relevant concepts and methods, and institutional organizations.
Remote sensing is the acquisition of information about an object or phenomenon without making physical contact with the object, in contrast to in situ or on-site observation. The term is applied especially to acquiring information about Earth and other planets. Remote sensing is used in numerous fields, including geophysics, geography, land surveying and most Earth science disciplines. It also has military, intelligence, commercial, economic, planning, and humanitarian applications, among others.
Geomatics is defined in the ISO/TC 211 series of standards as the "discipline concerned with the collection, distribution, storage, analysis, processing, presentation of geographic data or geographic information". Under another definition, it consists of products, services and tools involved in the collection, integration and management of geographic (geospatial) data. Surveying engineering was the widely used name for geomatic(s) engineering in the past. Geomatics was placed by the UNESCO Encyclopedia of Life Support Systems under the branch of technical geography.
Geoinformatics is a scientific field primarily within the domains of Computer Science and technical geography. It focuses on the programming of applications, spatial data structures, and the analysis of objects and space-time phenomena related to the surface and underneath of Earth and other celestial bodies. The field develops software and web services to model and analyse spatial data, serving the needs of geosciences and related scientific and engineering disciplines. The term is often used interchangeably with Geomatics, although the two have distinct focuses; Geomatics emphasizes acquiring spatial knowledge and leveraging information systems, not their development. At least one publication has claimed the discipline is pure computer science outside the realm of geography.
A GIS software program is a computer program to support the use of a geographic information system, providing the ability to create, store, manage, query, analyze, and visualize geographic data, that is, data representing phenomena for which location is important. The GIS software industry encompasses a broad range of commercial and open-source products that provide some or all of these capabilities within various information technology architectures.
Geographic information science or geoinformation science is a scientific discipline at the crossroads of computational science, social science, and natural science that studies geographic information, including how it represents phenomena in the real world, how it represents the way humans understand the world, and how it can be captured, organized, and analyzed. It is a sub-field of geography, specifically part of technical geography. It has applications to both physical geography and human geography, although its techniques can be applied to many other fields of study as well as many different industries.
The Wildlife Enforcement Monitoring System (WEMS) Initiative, brainchild of environment policy researcher Remi Chandran, is an environmental governance project developed for assisting in monitoring the effectiveness of enforcement and compliance of wildlife law at a national level. The purpose of WEMS initiative is to monitor trafficking and illegal wildlife crime through a joint effort carried out by United Nations bodies, national governments, private industries, civil society and research institutions, by building a common data collection and reporting mechanism at a national level. The project plans to bring together various national institutions to a common information sharing platform and thereby building the capacity of the states to manage knowledge on wildlife crime trends and threat assessments. The compiled data will be then analyzed and selected non nominal information will be made available online through the WEMS website. WEMS will also help in providing analysed information electronically to all the national enforcement agencies and international policy makers including Interpol and CITES Secretariat. Selected information will be shared with the public for bringing awareness about wildlife Crime. The WEMS initiative works by bringing together Customs, Police, and Forest to a common information sharing mechanism within the national government and this will improve inter agency cooperation in tackling environmental crime holistically. Research and analysis of the crime data will be carried out through a designated national research Institute which will also carry out policy analysis identifying the trends and reasons for non compliance. It will also attempt to analyse the legal decisions on wildlife crimes from data obtained from local courts and will be able to identify weakness in legislation if any. Apart from this, the carriers involved in the illegal trade will also be recorded.
The Wildlife Enforcement Monitoring System will provide the platform for our enforcement agencies to collect and share information on the trends and patterns of wildlife crime. Moreover, the cross-border nature of wild life crime underscores the need to enhance cooperation among our governments and to pool financial and human resources. I am confident that these measures will go a long way in enhancing our capacity to protect our wildlife resources.
Digital Earth is the name given to a concept by former US vice president Al Gore in 1998, describing a virtual representation of the Earth that is georeferenced and connected to the world's digital knowledge archives.
Geospatial metadata is a type of metadata applicable to geographic data and information. Such objects may be stored in a geographic information system (GIS) or may simply be documents, data-sets, images or other objects, services, or related items that exist in some other native environment but whose features may be appropriate to describe in a (geographic) metadata catalog.
A spatial data infrastructure (SDI), also called geospatial data infrastructure, is a data infrastructure implementing a framework of geographic data, metadata, users and tools that are interactively connected in order to use spatial data in an efficient and flexible way. Another definition is "the technology, policies, standards, human resources, and related activities necessary to acquire, process, distribute, use, maintain, and preserve spatial data". Most commonly, institutions with large repositories of geographic data create SDIs to facilitate the sharing of their data with a broader audience.
The Remote Sensing and Geospatial Information System training centre is located in University of Pune, India's premier institute for graduate and post graduate courses. The courses offered for GIS and RS here are held under the Department of Geography.
Geography is the study of the lands, features, inhabitants, and phenomena of Earth. Geography is an all-encompassing discipline that seeks an understanding of Earth and its human and natural complexities—not merely where objects are, but also how they have changed and come to be. While geography is specific to Earth, many concepts can be applied more broadly to other celestial bodies in the field of planetary science. Geography has been called "a bridge between natural science and social science disciplines."

The Global Navigation Grid Code (GNGC) is a Chinese-developed point reference system designed for global navigation. It is similar in design to national grid reference systems used throughout the world. GNGC was based upon the work of the GeoSOT team, headquartered in the Institute of Remote Sensing and GIS, Peking University. The concept for this system was proposed in 2015 in Bin Li's dissertation: Navigation Computing Model of Global Navigation Grid Code. GNGC allows easy calculation of space and spatial indexes and can be extended to the provide navigation mesh coding. Along with the Beidou navigation system, GNGC provides independent intellectual property rights, globally applicable standards and global navigation trellis code.
