GIS is more than just creating a map and it is more than just data. GIS is used in many industries and fields of work. I started out learning GIS and using it when I worked in the oil and gas industry. I used it with clients to track their assets and oil and gas leases. I am currently applying GIS in archaeology and history. There is a myriad of ways to use GIS but just what is GIS. Follow the link in the below paragraph to peek your curiosity and learn more about this relatively young technology and its application.
This is probably the most asked question posed to those in the Geographic Information Systems (GIS) field and is probably the hardest to answer in a succinct and clear manner. GIS is a technological field that incorporates geographical features with tabular data in order to map, analyze, and assess real-world problems. The key word to this technology is Geography – this means that some portion of the data is spatial. In other words, data that is in some way referenced to locations on the earth. Coupled with this data is usually tabular data known as attribute data. Attribute data can be generally defined as additional information about each of the spatial features. An example of this would be schools. The actual location of the schools is the spatial data. Additional data such as the school name, level of education taught, student capacity would make up the attribute data. It is the partnership of these two data types that enables GIS to be such an effective problem solving tool through spatial analysis.
GIS operates on many levels. On the most basic level, geographic information systems technology is used as computer cartography, that is for straight forward mapping. The real power of GIS is through using spatial and statistical methods to analyze attribute and geographic information. The end result of the analysis can be derivative information, interpolated information or prioritized information.
