How would you define GIS in your own words?
GIS stands for Geographic Information Sytems which involves mapping data, spatial analysis and statistics, remote sensing, analyzing high altitude and satellite imagery for government, military, environmental, geologic and geography, and marine uses. Topics covered will include raster and vector analysis, spatially analyzing how mapped data projects a result or change, or results from an event (natural disasters, famine, disease, elections, population changes, real estate trends - pretty much anything can be mapped). Many students and adult learners in real estate, environmental, urban planning, geology, geography and remote sensing are required to understand different software programs (ESRI's ArcGIS Mapping & ArcGIS Pro, ENVI, Socet GXP, Erdas Imagine, or QGIS) to map land use and land changes, vegetation, species migration, urban planning, real estate trends and valuation, fire or other natural disasters. GIS requires identifying the problem, setting up the analysis, finding reliable and sound data to study this situation, and mapping it correctly using different software tools, and presenting the results in a visual format. The power of GIS is that this system is able to visually present data and tell a visual story either in layers of information, 3D format, or time trends (animation) rather than by static graphs and pictures.
How would you define GIS in your own words?
GIS is a bridge between the world we observe and the world we record. In this light, it can be seen as a tool that allows us to access, investigate, analyze, model, and make predictions from data that is being collected at a near continuous rate. But to use GIS effectively in this way requires the ability to observe, recognize, and think spatially—all on the phenomenal level. Thus, GIS must also occupy its own scientific space and be governed by its own methodological principles, which allow for the rigorous investigation of all phenomena, social and natural, on Earth.
