Geographic Information Systems (GIS) are used
to gather and synthesize data about locations and geology. Online GIS
courses are available in remote sensing, programming, modeling, spatial
analysis and GIS applications.
Overview of Online GIS Courses
Geographic Information Systems (GIS) are used to collect, organize,
store, analyze and present information related to location. Geographers,
cartographers, photogrammetrists, surveyors, mapmakers and software
designers are all examples of professions that utilize GIS. Universities
offer online GIS courses as continuing education or part of a
certificate or degree-granting program.
Course Requirements
Taking online GIS courses requires a computer with an up-to-date
operating system, high-speed Internet access and word processing
software. A sound card with speakers and monitor capable of high-color
16-bit display are also necessary. Some courses or schools may also have
specific suggestions regarding operating systems and processors.
List of Online GIS Courses
Remote Sensing Course
Students learn about remote sensing principles, detection
technologies, interpretation techniques and real-world applications.
Earth-observing technologies covered include satellite systems, aerial
cameras and electronic imaging. Students often discuss the
electromagnetic spectrum and radiation principles as they learn about
detectable energy sources and discover how to attain accurate
measurements using photogrammetric techniques.
Data Resources, Spatial Analysis and Modeling Course
This course discusses spatial thinking, analysis and modeling
concepts used in GIS technologies and applications. Students learn to
identify the type of information needed for a project and determine
whether quality data already exists or needs to be generated. A survey
of existing technologies for spatial analysis and modeling is provided.
Students gain experience utilizing some of these tools as they integrate
data and create models to solve spatial problems.
GIS Programming Course
This course provides an overview of GIS database needs assessment,
design, development and customization. Students are introduced to
programming basics and focus on ways of automating tasks to increase
functionality. Students learn to write code and utilize the latest GIS
software as they practice creating, maintaining and integrating
databases first-hand.
GIS Applications Course
This course covers the wide array of practical GIS uses, including
environmental impact assessment, natural resource management, geohazard
identification and natural disaster monitoring. Students learn how GIS
is used to inform decisions in various fields including strategic
planning, marketing, national security and urban planning. Exercises
employ GIS data sets and software to provide experience solving
real-world problems.
