What and where are the community’s needs?

What is the status of available resources?

Smart communities are already getting a comprehensive view of needs and resources by using GIS and even incorporating realtime sensor data and 3D visualization. Citizens and businesses are using open data and increased governmental transparency to collaborate and drive innovation. When you can see the entire, community-wide landscape, it is much easier to identify gaps in service or areas that need to become more livable, sustainable, and resilient. That clear view can be seen from a GIS platform — a way to view, map, share, analyze, and act on information about the community.

1. GIS Provides a Comprehensive View and Understanding

GIS pulls it all together and provides a clear view. Every feature and resource in the community has a location. You can use that location within your GIS to look at data from various sources, systems, or departments. You can analyze community assets in relation to other assets or features of the community to gain valuable context and greater understanding. In this way, location is the common thread needed to create a complete view of what is happening.

2. Go Deeper with Spatial Analysis

When you see data on a map, you gain insight. But GIS can help you do much more by providing you with spatial analysis capabilities. You can answer important questions:

Where is the best location for a new building or a community service offering?

Is there a relationship between disease and environmental features in our community?

What are the most efficient alternate routes a bridge is closed for repair?

Through your GIS, you can also use spatial information to make predictions by asking questions such as

Where are water contaminants most likely to flow?

and

Where will a fire most likely spread?

By using spatial analysis to answer questions and make predictions you give your community smarter use of its resources plus better services and increased safety for its citizens. The possibilities for spatial analysis are practically endless, limited only by the imagination and available data. Fortunately, new sources of data continue to emerge.

3. Sensors Provide a Valuable Source of Data

Communities have access to a new source of detailed, real-time spatial data, thanks to the expanding use of sensors for tracking, monitoring, and connecting many daily operations. Sensors can broadcast when a parking space is open, a city trash bin is getting full, or an energy turbine requires maintenance. When sensor data is combined with GIS, communities can see what is happening where and react more rapidly to events.

4. Community Engagement Adds to Your Data

Community engagement means that you can communicate directly with citizens and staff, and they can communicate immediately with you — reporting problems, locating services, and supporting local initiatives. Citizens can use their cell phones to voluntarily collect information about their surroundings and share that data with the community. You can use GIS to aggregate this and other data on a map to identify hot spots such as water conservation concerns, property damage, mobile health clinics, or areas in need of graffiti removal.

5. 3D Modeling and Visualization Improve Planning

Sensor data and community engagement within GIS give a clearer view of your community. You can make that view even more holistic by adding 3D visualization and analysis. Compare, for example, construction proposals of a new structure by viewing and analyzing them from every angle to see how each proposal fits into the landscape. You can make a more informed decision before any construction occurs. Urban planners and the public can see the potential impact of any proposed building in terms of issues such as where it will cast shadows, block views, or reflect heat. And it’s not just decisions about buildings that will benefit from a 3D view. When you see 3D representations of mass transit proposals, you get a more realistic view of the impact on communities and existing structures, so you can more accurately discuss the merits and concerns of proposed routes. The immersive nature of 3D visualization makes it an unparalleled tool for communicating community impact of a project design.

Case Study: Singapore uses 3D modeling to carefully plan growth on the already densely populated island. Singapore’s Urban Redevelopment Agency takes into account local planning guidelines for land parcels and applies local building templates to iterate feasible designs quickly. Lines of sight and changes to traffic patterns are easily assessed and viewed in the context of a 3D environment.

6. The Intersection of New Smart Technologies

3D visualization is an excellent tool for quickly understanding patterns in sensor data collected across the city and at different elevations. For example, you can collect noise pollution data at different locations and building elevations throughout the city and render that data in 3D. Likewise, you can look at the severity of air pollution measured by sensors in 3D to show areas where pollution needs to be mitigated.

Case Study: Esri partner, Valarm, used a GIS-based app to collect air quality data such as volatile organic compounds (VOC) around the University of Southern California (USC) campus in downtown Los Angeles, California. The sensor data was combined with GIS for 3D visualization.

7. Geodesign for More Sustainable and Healthy Communities

Given the global concerns of climate change and growing population, it is more important than ever to evaluate planning and design decisions related to the built environment within the context of the natural environment. Communities need access to geology, biology, ecology, hydrology, meteorology, and other scientific data during the design process. Geodesign is a formalized process for taking into account all the geographic information and stakeholder input available when deciding where and how to build.
