This large-format map, created for Discover Gilbert, showcases the town’s unique features and history through bright photography and engaging callouts. It highlights riparian preserves, foodie destinations, and a vibrant arts and culture scene, while a photojournalistic timeline traces Gilbert’s evolution from “Hay Shipping Capital” to “Phoenix’s Coolest Suburb.” Parks, golf courses, and cultural landmarks are located via a reference grid aligned to the town’s original surveyed Sections, a design choice that marries cartographic function with place-based storytelling. The design adopts Discover Gilbert’s lively palette and distinctive fonts, with locator insets for the greater Phoenix area, and drive time and direction. A silhouette of the Superstitions and the iconic Water Tower anchors the map in its sense of place.This map was almost entirely created in ArcGIS Pro. One of my favorite features is the reference grid that uses the street network. Fun fact: the purple alphanumeric tabs around the edges of the map are repeated in the side panels to help locate points of interest, and use text formatting tags for background, border, color, and font to show the coordinates in a purple box in-line with the text. Other fine cartographic details include the timeline, where the distribution of years is to scale, and the Drive Time and Direction map, where destinations and surrounding towns are placed accurately along concentric circles representing hours from Gilbert, positioned in the correct direction as the crow flies. Data sources include the HIFLD (now deprecated), Maricopa County, Town of Gilbert, Maricopa Association of Governments (a source that I discovered via the AGIC listserv!), Maricopa County Assessor, FAA, USGS NHD, OpenStreetMap, AZ GeoHub (thanks, AGIC!), NHPN, and Esri.
