Legal Boundaries: Start with “Why”

Several years ago, Simon Sinek gave a TED Talk on marketing—a business, services, products, even ideas and beliefs. Although his talk was focused on business success and inspiring leaders, the message, “start with why,” is easily transferable to winning in court as an expert. Since the essence of expert witness testimony is opinion-based, it is crucial to that testimony to have the ability of explain the “why” of your opinion. As Sinek reiterated in his talk, people do not buy “what” you do or “how” you do it—they buy the “why.” This will be true in court as well.

Path planning algorithms will bolster beyond visual line of sight UAV flights

While Canada and Europe are already relaxing their rules on flying UAVs outside the visual range of pilots, BVLOS (beyond visual line of sight) operations in the U.S. may still take some time for government approval due to airspace safety and security considerations. This is, of course, another classic case of technological innovation that’s out of step with bureaucratic rule making as more advanced algorithms for autonomous UAV navigation have now become more widely adopted and easier to deploy.

Finding and Preserving Lost Black Cemeteries: UAVs and ground-penetrating radar are making the work more successful and efficient

Communities across the country are rediscovering forgotten and lost Black cemeteries and documenting their history, using technology to map above and below ground. In late 2022, Congress passed the African American Burial Grounds Preservation Act, that will provide resources to locate, document, and preserve these often unmarked or abandoned sites through 2027.

Quantum Sensing: Profound change could be ahead for airborne reality capture and mapping, in the realm of quantum physics.

The term “quantum leap” is often used loosely to describe excitement over new technologies. This time, though, the “quantum” part is literal—specifically, “quantum sensing.” In this case, it is the leveraging of quantum physics, quantum mechanics, particle states, and properties to improve foundational geodesy, sensors, systems, and methods.

Aerial Construction Monitoring Solutions that Require No Pilot

In construction site monitoring, here are two solutions that require, in one case, no drone, and in another, a drone that requires no FAA-Part 107 certified operator.

Can traditional aerial photogrammetry survive in the era of uncrewed aviation?

On December 11, 2024, a photogrammetry aircraft registered N818BR made an unscheduled forced landing on a busy highway in the vicinity of Victoria, Texas. The pilot survived with minor injuries, three cars were hit with occupants suffering minor injuries, too. The aircraft was destroyed.

Maps as Art: Hijacking Cartography

Artist Ed Fairburn loves collecting all sorts of antique ephemera, but he has a particular soft spot for maps, which he uses as a canvas to express his art. For example, in this ink work over a map of Brooklyn (based on Cram’s 1894 Universal Atlas), Fairburn draws a human face along lines of roads, rivers and other map details–while carefully preserving the original character and functionality of the map. He calls this “hijacking cartography.”

MAPPS is the preeminent national association of firms involved in many aspects and benefits of the geospatial field in the United States. A cornerstone of MAPPS is being fully engaged in a non-partisan manner with the legislative process on issues that directly impact its membership and the geospatial profession.

This article summarizes several long-standing and highly effective MAPPS programs which demonstrate the associations’ dedication to Democracy in Action, public and private partnerships, and geospatial political advocacy. The programs below allow MAPPS members to engage in the political process by making their collected voices heard on Capitol Hill and with federal agencies:

Legislative Affairs Committee (LAC), Federal Programs Conference (FPC), Capitol Hill Day, Political Action Committee (PAC).

3D model maps of disappearing tropical glaciers reveal a stark warning for the cultural future of Uganda’s Bakonzo people

Project Pressure’s Klaus Thymann works with Kule Jocknus Bwabu Solomon, Muhindo Rogers of Uganda Wildlife Authority and glaciologist Heïdi Sevestre to set up precision points for photogrammetry survey.

Micro-drones, those that weigh less than 250 grams, are popular with recreational UAV flyers for several reasons. They are relatively inexpensive, with models starting at under $500. Additionally, the 249-gram-and-under category requires no FAA registration, nor do they fall under the remote ID (RID) regulation.

Now, with the aid of sophisticated flight planning and automated control software, micro-drones are tackling commercial operations such as construction monitoring.

A hybrid system for capturing land and water promises dramatically improved efficiency over legacy aerial approaches.

Capturing the four distinct elements of shorelines and coastlines often entails using two, three, or more separate systems. Zones of offshore, nearshore, the shoreline, and uplands, captured with separate systems, are stitched together—not always seamlessly. The zones represent a single ecosystem, and the latest approach captures it with one system.

Fresh Specs That Are Lifting the UAV Game

The latest UAV technologies released in the first quarter of this year seem to be bucking the trend of white-washed main frames and disappearing control buttons commonly seen in the last five years. Instead, the current crop of drones is gaining more advanced robotic payloads, as well as imbibing unconventional shapes that allow for better functions.

Plus, there’s a big jump in chip performance thanks to more advanced artificial intelligence technology. Here are the latest UAV specs that bring in the bells and whistles.
