Types of GIS Mapping

There are many different mapping styles in geographic information systems, ranging from category maps to bubble maps to heat maps, depending on the problem that has to be solved.

FREMONT, CA: A Geographic Information System(GIS) map is a must-have tool when portraying geophysical data about the world on the screen in a dynamic and interactive form. Without GIS map data, monitoring change, making educated decisions, and detecting geospatial trends is not possible today. There are many different mapping styles in GIS, ranging from category maps to bubble maps to heat maps, depending on the problem that has to be solved.

Category Maps

There is nothing like a category GIS map when one needs to know precisely which parts of the map correlate to which data segment. Because it is the simplest to generate, this is the most popular sort of GIS mapping. A different color is assigned to a specific category or attribute. Consequently, one will have a handy map of variously colored patches, each representing a different category.

Heat Maps

The term ‘GIS heat map’ is frequently misused to quantity maps; however, it refers to a distinct mapping convention. A basic idea of ‘warmer’ and ‘cooler’ regions can help when the data you need to show on the map is highly dense and mixed up. Especially if one knows that the hottest locations correspond to the densest concentration of the supplied quantity. Red is generally thought to represent heat, whereas blue is said to represent coolness. It is not really accurate, but it does provide a fair view of amount distribution.

Bubble Maps

A bubble GIS map illustrates how shapes and their size differences can be used to make the presentation of complex numerical data easier. Consider the situation when comparing the number of people who use certain slang phrases in various areas. On the GIS map, larger and smaller bubbles will represent more and fewer people, respectively. One receives bubbles instead of monotonous rows and columns of numbers. This saves time and effort by providing a rapid basic knowledge of the link between numbers and locations at a glance.

Cluster Maps

Colors, forms, and labels are successfully combined in this kind to cluster densely packed points of data together. To put it another way, there are too many points to display on the GIS map individually; thus, they are merged into a single cluster point for ease.

Quantity Maps

Color-coding is used on a GIS quantity map, but different shades of the same color are used to represent the variation in amounts of the item depicted on the map. It is an ideal GIS mapping solution for seeing a large amount of detailed data spread out over a large area.
