Introduction For additional visual reference when working with the GeoCue Map View, you can add layers in the Map View that are ‘mapping’ to a Web Mapping Service. It is often the case that you will continually reuse a small set of WMS layers within your GeoCue projects. To make this easy to set-up, we…
Geiger-mode lidar data is getting a lot of press lately as the “next big thing” in airborne data collection. Unlike traditional lidar sensors, which we will call “linear-mode lidar” for convenience, Geiger-mode sensors use a different detection method in the receiver – the “Geiger-Mode” part – to enable much higher data collection altitudes and higher…
When using imagery as a source of metric measurement, an up-front task that must be accomplished is determining the exact position (X, Y, Z) and orientation (Pitch, Yaw and Roll) of the camera at the precise time of each image exposure. This seven tuple of data is termed the dynamic exterior orientation (DEO or often…
