There are two common types of coordinate systems used in GIS: A global or spherical coordinate system such as latitude–longitude. These are often referred to as geographic coordinate systems. A projected coordinate system based on a map projection such as transverse Mercator, Albers equal area, ...
Map projection selection is a complex process involving an evaluation of map projection alternatives based on a set of characteristics that describe these projections and the types of analysis to be performed. This paper presents a prototype expert system for selecting the suitable map projection. The...
Here are some more helpful references for map projection types: What are Map Projections? Map Distortion with Tissot’s Indicatrix Cylindrical Projection: Mercator, Transverse Mercator, and Miller Conic Projection: Lambert, Albers, and Polyconic Azimuthal Projection: Orthographic, Stereographic, and Gnomon...
The most critical issue in dealing with coordinate systems is knowing what the projection is and having the correct coordinate system information associated with a dataset. There are two types of coordinate systems—geographic and projected. A geographic coordinate system uses a three-dimensional ...
SELECTING SUITABLE MAP PROJECTIONS IN MINIMIZING DISTANCE DISTORTIONS IN GIS-BASED APPLICATIONS: A CASE STUDY FROM TURKEY As a result, it was seen that equidistant map projection selection in the GIS application gave more sensitive results in terms of distance. KEYWORDS: GIS... F Yildirim - 《Fre...

The goal of an application plays an important role in choosing one of those projections. Choosing the equal-area projection for an application in which area information is used (forestry, agriculture, ecosystem etc) reduces the amount of distortion on the area, but many users using GIS ignore ...

Map Projection Types In order to choose the optimal map projection for your map there are many things that you must consider. Projection Properties:You must consider the projection properties and whether those properties are compatible with the purpose of your map. For instance, if you want users...
