What is Geospatial Technology?

Geospatial Technology incorporates elements of Remote Sensing, Global Positioning Systems, and Geographic Information Systems (see descriptions below) to better understand the human and physical processes which shape our world. Through the use of Geospatial Technology, one can analyze, manipulate, and visualize features of the earth in new and exciting ways.


Remote Sensing (RS)

A remotely sensed image is derived from spacecraft, satellites, or aircraft at small and large scales of coverage. Many types of remote sensors are regularly recording images of the Earth for a multitude of purposes, and can capture areas which may be otherwise difficult to access.

Applications of remotely sensed imagery include: landscape and vegetation analysis, natural hazards mitigation, urban growth and development, and agricultural monitoring.

Global Positioning Systems (GPS)

The system of twenty-four satellites orbiting the Earth and transmitting data to stations on the ground is known as the Global Positioning System. Through measurements as accurate as one centimeter, GPS can detect even the slightest movements in land or building sites. It is one of the foundational elements of technologically-advanced mapping systems, and provides precise location information for land surveys, agriculture, mining, and construction operations.

Geographic Information Systems (GIS)

A Geographic Information System is a combination of hardware, software, data, and personnel which allows a user to collect, create, display, update, and disseminate geographic information in a wide variety of applications. GIS is a powerful tool to examine geographic patterns which may not be evident through the use of raw data or paper maps alone. Industries benefitting fro;m the use of Geographic Information Systems include conservation agencies, transportation, government, real estate, economic development organizations, military, and many more.
