What is GIS data management?
It is a system for managing information, organizing and visualizing maps and data, and analyzing relationships and patterns over any geography. This allows you to design, plan, and perform predictive analytics.
What are the four types of GIS data?
The three types of GIS Data are -spatial, –attribute, & —metadata
- vector data.
- raster or grid data (matrices of numbers describing e.g., elevation, population, herbicide use, etc.
- images or pictures such as remote sensing data or scans of maps or other photos.
What are data types in GIS?
There are two different types of GIS data, vector data and raster data.
What are the main functions of GIS?
Functions of GIS include: data entry, data display, data management, information retrieval and analysis.
How is GIS used?
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 like there).
What are the uses of GIS?

What is a GIS?
Basic GIS concept A geographic information system (GIS) is a conceptualized framework that provides the ability to capture and analyze spatial and geographic data.
What is the main source of data for GIS?
In developing a digital topographic database for a GIS, topographical maps are the main source, and aerial photography and satellite imagery are extra sources for collecting data and identifying attributes which can be mapped in layers over a location facsimile of scale.
Is there a time-variant GIS database of changing historical administrative boundaries?

What is data representation in GIS?
Data representation. GIS data represents real objects (such as roads, land use, elevation, trees, waterways, etc.) with digital data determining the mix. Real objects can be divided into two abstractions: discrete objects (e.g., a house) and continuous fields (such as rainfall amount, or elevations).
