Open Source Geospatial Information Systems

In 2012, the United Nations Global Geospatial Information Management Expert Committee requested a document explaining the future trends in geospatial information management. This article focuses on one of the open source trends. In this article I will explain the trends of geographic information systems (GIS), its importance, and open source challenges and opportunities. Also, we will focus on the influence of open-class GIS software on graduation classes and consider this trend from the perspective of the world and South Africa.

GRASS GIS is generally called GRASS (geographical information analysis support system) and it is a free open source for geospatial data management and analysis, image processing, graphic and map creation, space modeling, and geographic information system Geographic Information System (GIS) software suite Visualization GRASS GIS is currently used in academic and business environments around the world, as well as many government agencies and environmental consulting firms. It is a founding member of the Open Source Geospatial Foundation (OSGeo).

What is Geospatial Collaboration? According to LPA Systems, Inc., geospatial collaboration "only uses geospatial information to collaborate" (Wolfe, Russell, Corridoni). Geospatial collaboration is a subset of geographic information systems, or what is commonly called GIS. GIS is a tool for "get, save, analyze, and display geographic information". GIS can be implemented in a variety of applications such as search and rescue to better plan and coordinate future events.

The Geographic Information System (GIS) plays a constantly changing role in geospatial information (GEOINT) and the national security of the United States. With these technologies, users can efficiently manage, analyze and generate geospatial data, combine GEOINT with other forms of information gathering, and analyze and visualize highly evolved geospatial data. Therefore, GIS can generate a new and reliable GEOINT to reduce decision makers' uncertainty. As the GIS program is web-based, users can work with decision makers to solve GEOINT and national security related issues from anywhere in the world. There are various kinds of GIS software used in GEOINT and National Security, such as Google Earth, ERDAS IMAGINE, GeoNetwork open source, Esri ArcGIS and others.

The importance of the geographic information system (GIS) in the modern world can not be underestimated. Demand for geospatial data and geospatial information (GEOINT) continues to grow exponentially. Geospatial science and data become an important element in more and more fields and are an important part to solve the most difficult problems and problems in all walks of life. Geographic information systems can be found in almost all fields from agriculture to zoology, from A to Z. The US Geospatial Information Authority (NGA) is a GEOINT Information Community (IC) and a Department of Defense function manager. NGA is responsible for generating geospatial information and information to support our national security initiative.
