What is Cartesian Coordinate System?

Cartesian coordinate systems are an essential tool in mathematics, physics, engineering, and many other fields. They provide a way to describe the position of points in space using numerical values, which can be used to solve equations, plot graphs, and analyze data. In this blog, we will explore what Cartesian coordinate systems are, how they work, and why they are important.

Topology – Its all about relationships

In a GIS, topology means storing object relationships in the database. There are two ways of handling relationships. One way is to derive them on-the-fly when requested by the user. This is the approach used when we invoke the distance calculation command to compute the distance between two arbitrary points.

What is Geographic Coordinate System (GCS)?

The geographic coordinate system (GCS) is a spherical or ellipsoidal coordinate system for measuring and communicating positions directly on the Earth as latitude and longitude. It is the simplest, oldest and most widely used of the various of spatial reference systems that are in use.

What is Global Positioning System (GPS)?

The Global Positioning System (GPS) is a satellite-based radionavigation system. It is one of the global navigation satellite systems (GNSS) that provides geolocation and time information to a GPS receiver anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites. Positioning facility is freely accessible to anyone with a GPS receiver.

What is Geographical Information System (GIS)?

A geographic information system (GIS) is a system that creates, manages, analyzes, and maps all types of data. GIS connects data to a map, integrating location data (where things are) with all types of descriptive information (what things are).
