GIS is a framework for gathering, managing and analyzing spatial data by overlaying layers of information on maps and in 3D scenes. It integrates data from many sources and reveals patterns and relationships to help users make better decisions. Key aspects of GIS include using both raster (grid) and vector (line/polygon) data formats to represent geographic features, as well as processes for capturing, surveying and scanning spatial data. The implementation of GIS in an organization depends on its intended roles and can take different forms with varying impacts.
2. Simple understanding to GIS:
GIS stands
for Geographic
Information
Systems.
01
GIS = Spatial +

02
GIS = Overlaid
layers. (one of the
discipline of spatial
data sciences)

3. GIS Defination:
• A geographic information system (GIS) is a
framework for gathering, managing, and analyzing
data. Rooted in the science of geography, GIS
integrates many types of data. It analyzes spatial
location and organizes layers of information into
visualizations using maps and 3D scenes. With this
unique capability, GIS reveals deeper insights into
data, such as patterns, relationships, and
situations—helping users make smarter decisions.
4. This is changing the way the
world works:
• Determination of the role and scope of
GIS in the organization leads to the
appropriate model for implementation
and management. Although GIS can play a
wide variety of roles in organizations, few
characteristic GIS implementation types
exist. Each situation has different impacts
and implications.
6. GIS Files Formats:
• The two major types of GIS file formats are
• Raster and vector.
• Raster formats are grids of cells or pixels.
• Raster formats are useful for storing GIS data that
vary, such as elevation.
