    “Itiner-e aims to host the most detailed open digital dataset of roads in the entire Roman Empire. The data creation is a collaborative ongoing project edited by a scholarly community. Itiner-e allows you to view, query and download roads. Each road segment has a URI that allows it to be cited and linked by external resources.

    “The Roman Empire’s road system was critical for structuring the movement of people, goods and ideas, and sustaining imperial control. Yet, it remains incompletely mapped and poorly integrated across sources despite centuries of research. [They] present Itiner-e, the most detailed and comprehensive open digital dataset of roads in the entire Roman Empire. It was created by identifying roads from archaeological and historical sources, locating them using modern and historical topographic maps and remote sensing, and digitising them with road segment-level metadata and certainty categories. The dataset nearly doubles the known length of Roman roads through increased coverage and spatial precision, and reveals that the location of only 2.737% are known with certainty. This resource is transformative for understanding how mobility shaped connectivity, administration, and even disease transmission in the ancient world, and for studies of the millennia-long development of terrestrial mobility in the region…”

  3. A Free Tool [DeFlock] Maps The License Plate Readers On Your Route [Flock, Etc], Then Lets You Slide Right Past Them

    • The tool arrives as scrutiny of license plate readers continues to grow.
    For years, automated license plate readers have quietly spread across America. They sit on utility poles, at intersections, near shopping centers, and along roads most drivers use every day. The overwhelming majority of motorists never notice them.

    “Automated License Plate Readers (ALPRs or LPRs) are AI-powered cameras that capture and analyze images of all passing vehicles, storing details like your car's location, date, and time. They also capture your car's make, model, colour, and identifying features such as dents, roof racks, and bumper stickers, often turning these into searchable data points.
    These cameras collect data on millions of vehicles regardless of whether the driver is suspected of a crime. These systems are marketed as indispensable tools to fight crime, but they ignore the powerful tools police already have to track criminals, such as cell phone location data, creating a loophole that doesn't require a warrant…”
