Why My Photogrammetry Software Doesn’t Support Image Attitude

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...

Do you Need RTK for your Geo-MMS UAV Mapping System?

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...

Does Geo-MMS UAV LiDAR Work in Snow Covered Areas?

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...

LiDAR Intensity: What is it and What are it’s applications?

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...

How to Increase the Point Density of Your LiDAR System

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...

Fiber Optic Gyro: Do I need one for my Geo-MMS System?

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...
