What is reference map?
Reference maps are maps that help us determine features of the world in which we live. These maps show a selection of physical and/or cultural features through a map. These physical features include rivers, mountains, and geology. Cultural features include towns, roads, and time zones. Classrooms and atlases include reference maps to teach students about geographic features or to help you navigate through them. I remember learning the states from an old pull-down political map in the classroom. Someone had circled the word Florida, likely out of hopes for a vacation. Specialists, like geologists, also use several reference maps to learn about topography and help see what is underground. You can even help them by becoming a GIS specialist to create maps of the world together with GIS. To become such an expert, you must take a course and get the appropriate specialty and a certificate to prove it. If you’re having trouble deciding, I’ve reviewed the best online GIS certificate programs here. I hope you will find it useful.
What are political maps?
Political maps display a selection of human-made features such as borders and cities. They also show some physical features, such as rivers, but do not show topological features. A world map showing countries and major cities is a political map, as is one showing counties within a state. Political maps are often used for teaching or display. However, they can be used to assert international border claims.
What is a cartogram?
Cartograms rescale areas on a map to represent a count about a feature. You may have seen this in a world map where the size of the countries represents population – with a fat India. These maps are great at showing numbers, but the reader has to have a basic understanding of maps in order for a cartogram to make sense. Here you can find the famous Washington, DC Metro cartogram and compare it to maps that show distance and actual location.
What is a dasymetric map?
Dasymetric maps are similar to proportional symbol maps. They show dots representing data over a geographic background. But a dasymetric map has a better way of representing populations, moving dots to where people live makes a more accurate map. This method requires an additional step to adjust the dots to density. On this website, the USGS shows some dasymetric population maps.
What does a thematic map tell us?
Then, we layer thematic maps over that to help you investigate a problem. Reference maps tell us what is there. Thematic maps tell us how it is there .

Here is a great video t…
Reference Maps
- Reference maps show the reader what is where. They once illustrated qualities that do not change, or that change very slowly, but with GIS they can more often represent changing or fluctuating data points like the flood stages of a river. 1. Political mapsdisplay a selection of human-made features such as borders and cities. They also show some physical features, such …
Thematic Maps
- Thematic maps help us ask questions across an area of space. They focus on one topic to make a point, or multiple ideas to help support analysis. Thematic mapping sits at the heart of GIS, which allows us to use thematic maps to analyze and understand complex interactions of data. 1. Weather mapsare the thematic map most of us are very used to seeing. They display details of …
Conclusion
- Reference vs thematic maps is an everyday question for a GIS student, analyst, or programmer. Reference maps are used to communicate location on more static data points. Thematic maps communicate information in a geographic display where the map part is essential, but not the main idea that the map communicates. For a quick review on reference vs t...
