Parallax is an effect that occurs when the position of an object is viewed from different locations. The most common type of parallax is horizontal parallax, which is the apparent shift of an object against a background when the observer moves. In a GIS, parallax can be used to create the illusion of three-dimensional space on a two-dimensional map. Parallax can also be used to create an animated effect when scrolling through a map or image.
In GIS services, parallax is the difference in apparent position of an object viewed along two lines of sight, and is used in the stereoscopic analysis of remote sensing data.
The use of parallax in GIS services can help organizations improve the accuracy of their data and make better decisions. By using parallax, organizations can account for the different perspectives of data providers and create a more accurate picture of their data. This can lead to better decision making and improved outcomes.
