What is 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 like there). This provides a foundation for mapping and analysis that is used in science and almost every industry. GIS helps users understand patterns, relationships, and geographic context. The benefits include improved communication and efficiency as well as better management and decision making.
How is GIS used?
Hundreds of thousands of organizations in virtually every field are using GIS to make maps that communicate, perform analysis, share information, and solve complex problems around the world. This is changing the way the world works. GIS helps in Mapping, Data Collection and Analysis, also ease our daily through APPS for Smartphones, PC etc.
Getting Started with GIS Mapping Tools
GIS maps allow a company or organization to find and display meaningful spatial patterns in data. It’s a big toolbox, and the tools are often used simultaneously. So where to start?
Go back to basics.
Think about what problem you are looking to solve. That will help you determine where to focus your efforts. GIS mapping tools are often divided into four categories: desktop, web, server and specialized.
Some tools—such as Esri ArcGIS Pro, Esri Story Maps, and QGIS—are the most commonly used.
ArcGIS, produced by Esri, is the flagship product and one of the most widely used in GIS mapping, including ArcGIS Online, which transports desktop mapping into a web environment.
QGIS is a free, open-source tool, which makes it very accessible and popular among mappers.
Esri Story Maps, another free program, provides context and supporting information, so it can be a stand-alone resource.
All three of these applications can be used to:
Transform data into a map
Perform queries and visualizing the results
Connect a spreadsheet with map data
Geocode addresses
Edit attribute data and geometry
With desktop applications, you can add layers — styled as a stroke, fill or label — to maps to make comparisons. You can also create selection sets, which allow you to manipulate or highlight just one part of a map, to pull out details.
