I recently ran a post on the weather durability of the Leica ScanStation Px line (P16, P30, P40) and really for all of Leica's mapping products as the weather durability (IP rating) is phenomenal across the board. You can read my original post here, which includes a description of IP ratings. Following this post, I heard both directly and through the grapevine from several detractors of this piece to three main points:
- It wasn't raining hard enough!
- Let's see the raw data so we can see for ourselves!
- The data quality is questionable—the rain would cause refraction of the laser!
I'm here again to address these statements. Continue reading

Rain delays, snow days, heat advisories, and freeze warnings…we can take it. We’re Leica, and WHEN IT HAS TO BE RIGHT…RIGHT NOW, there are no better 3D laser scanning options with which to head into the elements.
I just finished over 7.5 years as a crime scene supervisor for a sheriff’s office CSI team within a crime lab and 15+ years as a CSI. In my last 5+ of those years, I was a Leica ScanStation user. During that era, our Leica ScanStation and the USPS mail carriers had one thing in common: Continue reading

With OSAC forensic standards on the horizon, it’s a good idea for both individuals and agencies to be proactive. Those who have already adopted forensic scanning are well-positioned for the future because the laser scanner’s objective collection of evidence, I believe, will make it a foundational piece of the reforms.

Here's the setting...a man is lying dead in the street. Expended cartridge cases are strewn about...9mm, 40 cal, maybe more... Miscellaneous items of UNKNOWN VALUE are spread up and down the block...or around the parking lot...or at various places around the park...wherever it is that you are working. Thunder rumbles in the distance. No, this is not the beginning of the next great mystery thriller...okay, so it may be that also...but what it is, is the beginning of MANY, MANY crime scenes that are worked across the country, every single day.
When prosecuting a homicide, it’s not unusual for defendants to claim self-defense. However, it can be difficult to determine whether those assertions are true. In these cases, 3D laser scan data can give detectives valuable insight. Criminalist Steven Alexander, of the Cincinnati Police Department’s Homicide Unit and Criminalistics Squad, recounts one case in which their Leica ScanStation and supporting software helped corroborate a robbery victim’s claim of self-defense.

National Law Enforcement Officer Memorial Fund will soon begin the solemn process of engraving new names into the marble walls of the National Law Enforcement Officers Memorial in Washington, D.C. Each of the 252 names being added this year represents an officer who made the ultimate sacrifice in the line of duty, including 123 officers who died in 2015.

Two years ago, the Royal Canadian Mounted Police in Brandon, Manitoba, became the first law-enforcement agency in the province to adopt forensic laser scanning. “We initially bought a single Leica ScanStation to ensure that it would meet our needs and that the workflow wasn’t going to be overly cumbersome, especially the back end of the workflow at the office,” said Cpl. Byron Charbonneau, of the Forensic Collision Reconstruction unit. “We liked what we saw, so we purchased additional units for both the collision and forensic identification side of the business.” Continue reading
As a detective, Victor Pizzola used to build cases and drop them off at the district attorney’s office for prosecution. Now the criminal investigator for the Albany County District Attorney’s Office is on the receiving end, taking what’s already been built and helping the prosecutors prepare cases for trial.
The position has given Pizzola a new perspective on the criminal justice process. But when he made the transition in May 2015, he brought along valuable insight of his own, not only from years as a detective in the Albany Police Department’s Forensic Investigations Unit but also in the use of the department’s laser scanning technology.
