GIS Application Development

GIS stands for Geographic Information System - technology for collecting, editing, transforming, analyzing and displaying spatial data - and GIS apps refer to software built around this core technology.

These applications, which can be web, computer or mobile based, often use maps or other spatial representations to overlay or assess data with a geographical factor. As such, their core functionality often differs from traditional applications.
However, it’s perhaps better to say that there are two factors for GIS - the technologies that collect the data and the tools that format and analyse them. To have a useful GIS system, you need both.

GIS Mapping

It’s well known that airplanes don’t fly in a straight line, as they use the curvature of the earth to their advantage. GIS applications play a role here.
A world map can show either the correct sizes of countries or their correct shapes, but it can’t do both. GIS takes data from maps that were made using different projections and combines them so all the information can be displayed using one common approach.

This is because mapping has long been a challenge - something that GIS application development solves as feasibly as possible - due to the 3D curved nature of the earth. More specifically, how we typically try to represent this 3D data on 2D maps. For this, there are two factors: scale and projection.
