What are the main characteristics of spatial data?
Spatial data refers to the shape, size and location of the feature. Non- spatial data refers to other attributes associated with the feature such as name, length, area, volume, population, soil type, etc ..
What are the 5 components of GIS?
A working GIS integrates five key components: hardware, software, data, people, and methods. Hardware is the computer on which a GIS operates. Today, GIS software runs on a wide range of hardware types, from centralized computer servers to desktop computers used in stand-alone or networked configurations.

What is the main purpose of GIS?
A Geographic Information System (GIS) combines the visual elements and features on a map with the ability to link characteristics about these features in databases. This relationship provides a means for GIS to locate, display, analyze, and model information.
What are the importance of GIS?
The importance of GIS is well understood; it allows us to look at a location holistically, see patterns and trends we otherwise couldn’t, and make decisions based on the most comprehensive data available. Accordingly, GIS is an essential tool for realtors, government bodies, and engineers alike.
What are the types of GIS?

What is the main purpose of GIS?
A geographic information system (GIS) is a computer system for capturing, storing, checking, and displaying data related to positions on Earth’s surface. By relating seemingly unrelated data, GIS can help individuals and organizations better understand spatial patterns and relationships.
What are the advantages of GIS?
GIS allows users to organize, visualize, and analyze different layers of data by creating maps and scenes. With the ability to clearly visualize different types of data, users are enabled to uncover patterns, understand trends, monitor changes, and respond to events—facilitating better decision making.
What are the four application of GIS?
The GIS is used to study geologic features, analyze soils and strata, assess seismic information, and or create three dimensional (3D) displays of geographic features. GIS can be also used to analyze rock information characteristics and identifying the best dam site location.
