This option is used only for imagery acquired with high-accuracy, differential GPS, such as Real Time Kinematic (RTK) or Post Processing Kinematic (PPK). Fix Image Location for High Accuracy GPS (RTK and PPK)-When enabled, this option changes the Matching Neighborhood setting to Small (Optimized).The options allow you to define key adjustments to be used in the block adjustment process, tie point matching, and point cloud generation. GPU ID-Define a specific GPU ID to use for multi-GPU systems.CPU-Processing is restricted to the CPU only.CPU + GPU (default)-Processing is performed by both the CPU and GPU.Processor Type-Allows you to define how image processing is offloaded to the computer's hardware.Slide the bar to the left or right to adjust the number of CPU threads. CPU Threads-The number of central processing unit (CPU) threads dedicated to processing your project.Hardware-Configure CPU and GPU hardware options.3D Point Cloud-Allows you to choose whether to keep 3D point cloud files.True Ortho/Orthomosaic Tiles-Allows you to choose whether to keep ortho image tile files.DSM Point Cloud-Allows you to choose whether to keep DSM point cloud files.Keep Intermediate Products-Defines whether any intermediate products should be kept after processing completes.This scale allows the selection of the Ultra or High point cloud settings. User Defined-A resolution value can be manually defined in centimeters or pixels for the GSD.This scale defaults to the Low point cloud setting. 8x-For very large projects with high overlap, 8x Source Resolution can be used to speed up processing, which usually results in slightly reduced accuracy, as fewer features are extracted.

This scale defaults to the Medium point cloud setting. This scale is also recommended for very blurry or very low-textured images.

4x-Recommended for very large projects with high overlap, 4x Source Resolution can be used to speed up processing, which often results in slightly reduced accuracy, as fewer features are extracted.

1x (default)-Recommended image scale value.

Changing this value changes the resolution by multiples of the ground sample distance (GSD).

Automatic (default)-Uses the resolution of your source imagery.

Project Resolution-Defines the spatial resolution used to generate output products.

This is typically used only for rough testing. It is suitable for quick projects or testing.

Medium-Medium level of density point cloud.

This is the recommended setting for most projects.

High-High level of density point cloud.

Use for final products that require the highest detail possible.

Ultra-Highest level of density point cloud.

Point cloud settings are tied to the selected Project Resolution setting. To prevent the point cloud from becoming too sparse, it is recommended that you increase the GSD resolution in 2D Processing, as the point cloud density is decreased. Generally, point cloud densities below High should only be used for rapid assessment and testing. Increasing this value improves edge sharpness of features and increases processing time.

Point Cloud Density-Density of the point cloud used to derive the level of geometric detail of the resulting reconstruction.You can also save intermediate outputs and define how much processing power is used when generating those products. On the General tab, options are provided that allow you to adjust the quality and resolution of output products. To open the window, on the ribbon, on the Home tab, in the Processing group, click Options. Use the Processing Options window to configure which steps will run, the settings for each step, and which products will be created. You can run steps independently, minimizing the time required to generate the desired products however, you must run the initial step at least once. Drone2Map, you can adjust the processing options for a project to customize it.
