Gis infographic examples3/19/2024 ![]() In this example, I set the Philadelphia City Council Districts spatial dataset as the Data Driven Pages Index Layer because I needed to cycle through maps by district. At the very least, you’ll need an attribute column with integer values that determine the sort order of features. It’s important to structure the attribute data in a way that is compatible with Data Driven Pages. Select any vector feature as the Index Layer. Then, use the Index Layer as the bounding box of the entire map. ![]() Unless you need to display the Index Layer grid on the map, set the portions of the bounds of geometries in your Index Layer equal to the map layout dimensions. It may be necessary to edit features in the resulting Index Layer when using these tools, especially the Strip Map Index Features tool. Fill necessary options shown in the dialogue box. Navigate to ArcToolbox -> Cartography Tools -> Data Driven Pages and select the tool that matches your input feature type. The Grid Index Features tool works best for point or polygon inputs and the Strip Map Index Features tool works best for line inputs. You can use either the Grid Index Features or Strip Map Index Features tool to create a custom Index Layer. There are built-in tools in ArcMap that make it pretty straightforward to create an Index Layer using a vector feature input. If you set the portions of the bounds of geometries in your Index Layer equal to the map layout dimensions, you can use the Index Layer as the bounding box of the entire map. Think about how you would like to design your map layout to determine which Index Layer option will work best for your project. You have two general options for Index Layers: create an Index Layer or select an existing layer from your Data Frame. The driving force behind this tool is an Index Layer that includes the geometries for each feature you would like to use as the either the subject or frame of the map. I’m using ArcMap 10.5 in this example, but Data Driven Pages functionality is baked into ArcGIS Pro as well. Since I aimed to design one map layout that changes dynamically based on a list of geographies, I decided to use the Esri ArcMap Data Driven Pages tool. In addition to displaying text and numerical metrics on the page, we included maps and charts to visualize the story of transit performance in each district. In this example, we determined that a static design (rather than an interactive one) fit the needs of the advocacy group best, since they intended to share the documents as hard-copies or via email. The visualizations on each document represent data analysis results for a specific geography. The backbone of this workflow is a spatial dataset. I’ll walk you through a process that leverages a combination of software that data and GIS teams often have on hand. Nope, I’m not talking about D3.js, although you could build out a similar HTML template using the open source JavaScript framework. The project example in this outline was completed for a Philadelphia regional transit advocacy groups, PA for Transit and 5th Square, and aims to illustrate bus and trolley performance statistics for the routes that run through each City Council District. In this post, I’ll walk through steps that result in a series of custom infographics that correspond to a list of geographies. Delivering custom reports to City Council members helped the nonprofit win $1 million in funding. In the past, we used this formula for creating custom reports to help a nonprofit advocate for the need for high-quality childcare in the Philadelphia region. By telling representatives the story of how their jurisdiction compares to surrounding areas, you can help them understand the implications of their decision-making and drive conversation towards specific solutions for the people they represent. This data-driven method applies to a variety of use cases, including delivering custom reports to elected officials. ![]() Using a data-driven workflow will limit the number of files you’ll need to edit and maintain throughout the course of the project. Without an automated workflow, creating a series of infographics that have the same layout and information but are specific to unique locations can be time consuming and tedious. Infographics that combine maps, charts, and text help to tell the full story of a geographical area.
