Size of Flight

Number of Images 

The biggest factor in deciding the number of images you should collect during your flight will depend on your choice of photogrammetry software, as each one will have different requirements, as well as limits. A general rule of thumb to follow is to not try to process projects with more than 5,000 images per flight, but collecting more images will always render better results than attempting to process small datasets with limited images.  

If you do have a flight with more than 5000 images, we recommend breaking up the project into multiple flights and processing them as separate datasets during the photogrammetry stage, then combining them into one single dataset in post-processing.   

Point Cloud Density

If you have a point cloud that is over 3 GB in size, we recommend breaking up the project into multiple las files. If you have a flight with a point cloud density greater than 5000 points per square meter (ppsm), we recommend thinning the point cloud to reduce the density of points.
