From the pioneering SBC project and LGIView to NGA’s advanced requirements for “full geo” capability, this piece traces the development of GeoPDF standards, software adoption across key agencies, and the birth of TerraGo.

TerraGo turns 20 this year. To mark the occasion, we’re launching a series of articles exploring the history of GeoPDF and the software tools that produce, modify, and consume GeoPDF maps. In this inaugural post, we look at the early use of Portable Document Format (PDF) files and custom-built software systems that delivered geospatial applications—or GeoApps—to end users.

When it comes to public safety, lighting the way—literally—can make a powerful difference. A new study evaluating the Philly Streetlight Improvement Project (PSIP) shows just how impactful these programs can be.
