Leveraging Advanced Remote Sensing Technologies to Protect our Communities and Natural Resources Wildfires consume millions of acres of land every year, destroying homes, communities, and infrastructure across the United States and around the globe. Fire seasons are...

Does a Dual-Camera Drone Offer Better Coverage? “Give the customer what they need, but not what they want”. This is true for dual-camera drone configurations on UAV-LiDAR and photogrammetry mapping systems. These can be found in such products as Geodetics’...

LiDAR Sensors for UAV / Drone Application The Geo-MMS product suite is available with a wide range of LiDAR sensors. We classify LiDAR sensors into three categories: tactical, mid and long-range as illustrated below: When selecting the right LiDAR for your Geo-MMS...

Learn What Infrared or RGB Camera Works Best with Geo-MMS Systems The Geo-MMS product suite can now be equipped with a wide range of infrared or RGB cameras, as shown in Figure 1 below. The RGB camera can be used as a solo sensor with the Geo-Photomap product. Others...

And How Geodetics Geo-Photomap Photogrammetry Software Supports Image Attitude One of the main challenges in surveillance or photogrammetry systems mounted to multi-rotary UAV’s is the effect of vibration from wind, turbulence and pitching of the UAV. To address this...

PPK vs RTK Real-time Kinematic (RTK) and Post-processing Kinematic (PPK) are two related methods for improving GPS positioning accuracy – a technique commonly used in UAV mapping applications.  Both methods make use of differential processing to enhance...

Photogrammetry vs UAV LiDAR to Capture Snow Covered Areas Approximately, 40-50% of the land surface in the Northern Hemisphere is covered with snow during the winter session.  From a regional scale, an accurate mapping of snow cover plays an important role in...

Example Applications of LiDAR Intensity LiDAR intensity is recorded as the return strength of a laser beam. In the Geo-MMS LiDAR systems, it is a bi-product, provided as an integer number between 1-256. This number varies with the composition of the surface object...

LiDAR System Ideal for Aerial Mapping The primary reason that surveyors are switching from photogrammetry to LiDAR mapping systems is to obtain point clouds under trees, foliage and high canopies. This brings up the question: how can the point density of the point...

High Grade IMU for Mobile Mapping Systems A question that we often get asked from our customers is: “Do I need a Fiber Optic Gyro (FOG) IMU for my Geo-MMS system?”  The question can be restated as do we need a higher-grade IMU than MEMS-grade IMU’s for mobile mapping...

Combining BIM Modeling with Geo-MMS Products Another application of the Geo-MMS products is in Building Information Modeling (BIM). GeoBIM is emerging as a game changing strategy to solve contemporary multi-disciplinary challenges in our urban environments. This new...

Geo-MMS Offers Photogrammetry and LiDAR in One Payload The FAA Part 107 pilot license has opened the door to a wide range of new drone-based mapping applications that were previously prohibited by regulation.  New UAV-mapping technologies are rapidly finding their way...

Post-Processing-Kinematic and GPS Baseline Separation Our Geo-MMS customers using our liDAR mapping drone system often ask, “how far our system can fly from the base station for post-processing-kinematic (PPK) data processing?”. The short answer is about 10 miles...

Geo-MMS 'Resolutions' for the New Year Welcome to 2019. All of us at Geodetics hope you had a great holiday season and a happy New Year. We are excited about our 2019 mobile liDAR system product roadmap and our New Years’ resolution to expand the scope of capabilities...

GPS-MMS UAV Defense The US military is expanding it's uav defense strategies, turning to logistical purposes by expanding their abilities to defend against their enemies. In recent years, drones have become an integral part to government agencies as they have managed...

Geodetics Point&Pixel Geo-MMS LiDAR and Geo-Photomap utilize very different sensors and techniques for UAV mapping. Geo-MMS LiDAR directly geo-references LiDAR data to provide accurate and near real-time 3D point clouds. Geo-Photomap directly geo-references camera...

Geodetics Provides Images with Attitudes In the world of UAV Photogrammetry, the Aerotriangulation (AT) or the bundle adjustment is defined simultaneously refining the 3D model of captured images, estimating the camera position/attitude, and calibrating the camera. To...

Geo-MMS: From Flight Mission to Drone Flight Planning Three basic values must be known to correctly plan a data collection mission when using the Geo-MMS family of products: Appropriate flight altitude (AGL) Appropriate strip separation Appropriate flight speed These...

Geodetics Supports Map Coordinates in LiDAR Mapping Accuracy In drone-based LiDAR mapping accuracy, the drone’s trajectory used in georeferencing the LiDAR mapping point cloud, is typically computed in the WGS84 coordinate datum. This can be further represented in...

Turn your GPS/IMU ‘Black Box’ into a ‘White Box’ One of the key-components of a UAV/Drone mobile mapping system is the use and integration of a GPS/IMU module. The purpose of this module is to provide detailed accuracy of the trajectory path including position and...

LiDAR Drone Training and Customer Service Geodetics Geo-MMS family of products are in use all over the world. When purchasing a Geodetics mobile mapping system, first class customer service and top-notch drone training are available from Geodetics technical staff....

First Responders Quickly Adopt LiDAR Drones for Emergency Situations When it comes to emergency situations, first responders require agile real-time solutions which has led to first responders and drone usage increasing year over year. A real-time 3D map can provide a...
