Through the years, the ASU mascot, Sparky the sun devil, has gone through significant changes in his appearance. This Tempe map from 1962 takes a humorous approach to Sparky, showing him in many different recreations and professions. From cowboy to golfer to mer-devil, Sparky draws attention to professions and sites around Tempe. Knoell Homes likely wanted to draw attention to the town and their houses under construction.
In addition to the illustrations, this map also shows several sites that no longer exist. Next to the Salt River, pre Tempe Town Lake, you can see Tempe Beach Park. Further north is Tempe’s own theme park, Legend City, demolished in 1983. The “future site” of several local schools are labeled, likely to accommodate the growth of additional neighborhoods as advertised. Notice that Baseline Road marks the Tempe city limit. This map and many others in our collection show the changes to ASU, Tempe, and the greater Phoenix metro area over time.
The Map and Geospatial Hub is pleased to announce a recent acquisition of brand new, yet-to-be-released geospatial datasets for greater metropolitan Phoenix produced through the United States Geological Survey (USGS).
LiDAR-derived 3D building polygons and tree points, visualized with QGIS.
The data package includes raw, processed, and value-added products generated from a series of September/October 2014 LiDAR acquistion flights. Among the datasets included in the package are:
LiDAR reflective surface, bare earth surface, last return surface, and intensity surface datasets (0.5 meter spatial resolution),
LiDAR point clouds (available in 1km X 1km overlapping tiles),
a 2D building footprint polygon layer,
a 3D building polygon layer,
a forest polygon layer,
a tree point layer.
Over the coming weeks, the Map and Geospatial Hub will work to properly document these data with appropriate metadata and upload the layers into the ASU Geospatial Data Directory, and, eventually, into a forthcoming web-based geospatial data repository, along with the rest of our vast geospatial data holdings.
Spatial extent of new LiDAR coverage for greater metropolitan Phoenix.
These data make an exciting addition to the geospatial data landscape for greater metropolitan Phoenix. Applied research applications in the realms of urban geography, ecology, hydrology, land-use/land-cover change, urban planning, design, policy, livability, and sustainability abound.

Verona is perhaps best known as the setting of Shakespeare’s Romeo and Juliet. The city at the time this map was published was a picturesque layering of ancient Roman architecture as well as medieval and Renaissance Era structures.
Some notable landmarks include the Verona Arena, the Roman style amphitheater located in the center of the illustration and the Castelvecchio, the large castle just west of the arena. Another notable feature is the system of walls surrounding the city, spanning both sides of Adige River. Stretching over 10 km, the walls are a reflection of the city’s extensive history. Originally built by the Romans, they went through cycles of disrepair and restructuring throughout the centuries. Yet in most places, the base of the walls are still of the original Roman build. Whereas some cities underwent rapid change during the past few centuries, old Verona has stayed mostly the same albeit sprawling out into the neighboring countryside.
The city walls, the arena, even the streets remain nearly the same for this quaint city on the Adige River. Below the map is a modern view of the city with the walls outlined, as closely as possible, as depicted on the map for comparison.
