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...
