Concept Modules
Artificial Intelligence, Machine Learning, Deep Learning, and Internet of Things - By: Ann JohnsonThis Concept Module reviews the development of Artificial Intelligence and how it is used in applications and tools for geospatial technology. It also defines and reviews Machine Learning, Deep Learning, and the Internet of Things with real-world examples of how they are used.

Attribute Relationship - By: Wing CheungThis Concept Module reviews the use of color in visualizations of geospatial analysis emphasizing that both art and science are needed when choosing appropriate colors. It will look at how we see colors and how the different audiences may view colors based on cultural differences. Details are also given on choosing colors for different types of classifications.

Data Visualization and MAUP - By: Ann JohnsonThis Module reviews important cartographic concepts and topics when data is visualized in a map. This includes the map scale, projection, symbology, color and the boundary used to aggregate the data. This includes review of the Modifiable Areal Unit Problem and how a change in the boundary used for data can influence its interpretation.
|
Datum - By: Ann JohnsonThis Concept Module reviews what a datum is, differences between vertical and horizontal datum, how the datum have been created over time and plans to combine vertical and horizontal datum in the future. It includes the importance of a Datum for accurately locating features and the problems that can occur if all data sets in an analysis are not using the same datum.
|
Map Projections - By: Ann JohnsonThis Concept Module reviews the need to create a flat map for features on a spherical Earth. Topics include why distortions occur in the process of going from a sphere to a flat map, different types of map projections and what distortions occur and provides a rule of thumb for picking a projection based on a project’s specific needs.
|
Mathematical and Geospatial Technology, Part I - By: Ann JohnsonThis Module highlights how math relates to how computers work. It reviews basic mathematics principles such as number operations and computation. Definitions used in math are covered as well as Laws and decimal, binary and hexadecimal number systems.
|
Remote Sensing - By: Ann JohnsonThis module reviews important concepts in the use of remote sensed data including the electromagnetic spectrum, Passive and Active sensors, bands, composite images digital numbers, resolution (spatial, radiometric, spectral and temporal, and signature graphs. Also included is a brief discussion of classification methods.
|
Scale - By: Ann JohnsonThis concept module discusses the term of scale when used in geospatial technology. It gives examples of the use of the terms Large Scale and Small Scale when referred to maps. It includes reasons why it is important to use data created at the appropriate scale and to document in metadata the scale of the data you create.
|
Statistics - Basic Topics, Part I - By: Ann JohnsonThis Concept Module reviews the use of basic statistics for geospatial technology. Topics include descriptive and summary statistics, terms used for different statistical values (mean, median, and mode), standard deviation, variance, correlation coefficient and normal distribution.
|
Statistics - Basic Topics, Part II - By: Ann JohnsonThis Concept Module reviews the use of basic statistics for geospatial technology. Topics include descriptive and summary statistics, terms used for different statistical values (mean, median, and mode), standard deviation, variance, correlation coefficient and normal distribution.
|
Topology - By: Wing CheungThis Concept Modules briefly reviews Map and Geodatabase topology that are important to accurately model the geometric relationships in maps and in a geodatabase and preserve spatial integrity. It includes different types of typology between features and how it can help find data errors and fix them.
|
US Census History and Geography - By: Thomas MuellerThis Census Concept Module provides a brief history and reasons why the United States Census is important. It also covers what data is collected, how it relates to geospatial data, the two types of surveys that are collected and the structure of the geographic units that data is a reference to.
