How GIS is Used to Understand History
Historical geography is one area that has applied GIS to understand outcomes of battles, why cities were built in given locations, and using ancient technologies to understand length and difficulty of travel at different times of the year.
Real-time Collaborative GIS
Real-time collaborative GIS (RCGIS) enables users, from domain experts to common citizens, to collaborate on given issues and share data easily through a distributed framework.
4D GIS and Prediction
For the last two decades, GIS technologies have increasingly been used to incorporate not only spatial relationships but also analyzing and visualizing space across time. Spatial-temporal GIS, or 4D GIS, has, in particular, become essential in areas where GIS is needed for predicting dimensions across time.
GIS and NoSQL Databases
Relational databases present some limitations to scaling, preventing or limiting the applicability of big data and real-time data problems utilized within GIS. More and more GIS software companies and developers are adopting NoSQL formats where data retrieval is generally faster and easier to structure. NoSQL also facilitates analysis and integration within a variety of tools, which is why open source GIS has proven to be the most useful arena for NoSQL databases.
GIS and Natural Language Processing
Within GIS, natural language processing can be utilized for spatial understanding of where events, places, or people may relate to a given phenomenon.
New Earthquake Maps from the USGS Also Factor Human Activity Induced Causes
The United States Geological Survey has created a new map that highlights where natural and man-made earthquakes could cause damage around the country.
Google’s PlaNet: Geolocating Photos Using Artificial Intelligence
Google and researchers at the RheinischWestfälische Technische Hochschule Aachen University have developed an artificial intelligence system capable of identifying locations more consistently accurately than a human is able to do.
