Oriented Imagery in GIS: Unlocking Value From Unstructured Data
In an era defined by explosive data growth and rapidly expanding drone-based sensing, the geospatial community faces a new frontier: unlocking the value of unstructured imagery. Chad Lopez, a solutions engineer with Esri’s Imagery and Remote Sensing team, is at the forefront of this effort. In a recent interview, Lopez discussed how oriented imagery—raw photos...
GNSS Backup at the Atomic Level
A first-of-its-kind GNSS backup system provides independent navigation solutions using quantum magnetometry. This is a double-plus development. Not only is it a solution that dramatically outperforms certain other GNSS backup approaches, but it is a prime example of a solution that leverages quantum sensing. It is compact enough, light enough, and has a power consumption...

A Conversation With Spatial Storyteller, Pete Kelsey
Geospatial storytelling, geo-evangelism, and how to build the ultimate reality capture kit. By Pete Kelsey and Gavin Schrock, PLS The geospatial sector has a bona fide “geo celebrity”, and that distinction is well deserved. Pete Kelsey has been out there in the geo trenches with the rest of us for decades. Beginning with military service,...
The Surveyor and the “Geodesy Crisis”
Surveyor’s Corner By Tim Burch To the average professional surveyor, the term “geodesy” does not exist in their everyday conversations about the business. While the use of state plane coordinates has expanded greatly with the development of GPS/GNSS receivers and RTK/RTN connectivity, the mathematics and “black magic” of geodesy remains an enigma to most of...
From Meters to Centimeters
Understanding correction services for GNSS By Towfique Ahmed Real-time correction services were created to enhance the accuracy of Global Navigation Satellite Systems (GNSS), reducing errors from tens of meters to precise, centimeter-level measurements. While some applications can function with sub-meter accuracy—such as those supported by regional Satellite-Based Augmentation System (SBAS) solutions—surveying requires far greater precision....
