How can we use GIS mapping in our community?

A Geographic Information System (GIS) is a conceptualized framework that can record, store, modify, manage, analyze, and show a wide range of spatial and geographical data. This computer system is critical, particularly in planning, and is used to aid in planning and monitoring in various industries.

Data gathering for community assessment is an integral part of overall community programming, about which governing bodies are often unaware, underprepared, and may execute initiatives that are potentially ineffectual and irrelevant. To collect community data, various approaches are utilized, ranging from anthropological observations to key informant interviews and surveys. While these tools remain an essential element of the community’s toolkit, the information they produce is difficult for the individual to decipher. Furthermore, such statistics frequently fail to indicate the direct link between public and geographic location.



GIS technology is an important part of data infrastructure. It is often regarded as the technology, policies, standards, human resources, and related activities necessary to acquire, process, distribute, use, maintain, and preserve spatial data. GIS file formats consist of two major file formats; raster and vector.

  • Raster formats are cell or pixel grids that store GIS data and change over time, such as elevation or satellite images.
  • Vector formats are polygons made up of nodes (points) and lines. GIS data having defined borders, such as school districts or streets, can be stored in vector formats.

Any information that involves a location can be used by GIS. However, the area can be specified in various ways, including latitude and longitude, address, and ZIP code.

GIS allows you to compare and contrast different sorts of data including, public data, such as population, income, and education level. It can provide information on the land, such as streams, various types of flora, and soil. It also includes information regarding factories, agricultural sites, storm drains, highways, and electric power lines. 

GIS mapping is used to compare the locations of various objects to see how they connect. A single map may, for example, contain places that cause pollution, such as industries and areas that are vulnerable to corrosion, such as swamps and tributaries. GIS mapping aids in determining the areas where resources are most vulnerable. 

This article will discuss what GIS is and how it can be used in our community.


A Comprehensive View and Understanding.

GIS brings it all together and gives you a clear picture of your community. In GIS, there is a spot for every feature and resource through which you can look at data from numerous sources, systems, or departments using that location. You can examine your community assets in connection to other assets of the community to acquire helpful context and a better understanding. In this approach, the location serves as the connecting thread that allows you to get a complete picture of what’s going on.

When you look at a map, you automatically begin converting it into information by identifying patterns and detecting trends that might otherwise go unnoticed. You can comprehend where resources are today and where they will be in the future through spatial analysis.

Community leaders use GIS maps to identify where historical changes have happened and how plans will affect the community. This results in a more focused, well-researched decision-making process that is more in line with community goals.


GIS Sensors are a valuable data source.

The growing usage of sensors for monitoring, tracking, and linking daily processes, helps communities access a new source of precise, real-time geographical data. When a city garbage bin fills up, a parking space is available, or an electricity turbine requires repair, sensors can send out a signal. Communities can see what is occurring and react to situations more quickly when sensor data is coupled with GIS.

GIS is also used to overlay storm paths with sensor data to narrow down which electric utility equipment can be damaged by severe weather, lowering outage time and speeding service restoration. As communities adopt more modern technology, GIS will become increasingly important due to the rising reliance on spatiotemporal data.


Tracking of Vehicles.

Many cities are tracking the real-time location of police cars, public buses, snowplows, garbage, and trucks using GIS and sensor data. School buses are tracked, and drivers and operators are warned if they deviate from their planned routes. GIS tracking allows parents to follow their children’s movement to and from school and receive notifications a few minutes before pick-up and drop-off time.


Management of Natural Resources.

GIS technology aids in the management of natural resources, including agricultural, water, and forest, that are better maintained and managed using GIS mapping. Agricultural land management includes crop yield management, crop rotation monitoring, and other tasks that can be analyzed through GIS mapping. The Spatial Information System (GIS) is used to examine the geographical distribution of water, ensuring that accurate data is provided so that relevant measures can be taken.


Land cover and land usage are determined.

The feature that covers the barren landscape is referred to as land cover. The term “land use” means the surface area that is used for a particular purpose. The role of GIS technology in land use and land cover applications allows us to determine changes in various places. It also helps us identify and estimate land cover patterns over time while detecting abrupt land use and cover changes caused by natural processes or other actions such as deforestation.

Given worldwide concerns about climate change and population growth, it is more necessary than ever to evaluate planning and design decisions that affect the built communities’ surroundings. During the planning phase, communities require access to ecology, topography, biology, geology, hydrology, meteorology, and other scientific data to take relevant measures and a sustainable approach. GIS aids in implementing a systematic method, considering all relevant geographic information and stakeholder involvement, offering a more sustainable approach to communities all around.

The GIS community encompasses all five qualities that characterize an information community and is utilized in Geodesigns to automate the estimates of risk, sensitivity, hazards, capacity, proximity, vulnerability, accessibility, and other aspects that may be used to guide design decisions. Members of this information community use technology to exchange and distribute information, cooperate, and network with one another. For example, GIS Stack Exchange and GeoNet provide a platform for users to access information and share knowledge freely. Geography and mapping technologies can assist in opening and maintaining the communication channels needed to serve communities both inside and outside of a community effectively. Using a few accessible GIS apps to get started may help people form solid, long-term partnerships with their communities and the people around them.
