Basic Mapping
A software for processing drone captured-images into 2d and 3d maps
What is ESRI Drone2Map?
A single, geometrically corrected image “stitched” together from multiple drone photos
What is “orthomosaic”?
JPEG and TIFF
What is file types that can be used as input in ESRI Drone2Map?
Ground Control Point Viewer
What is a tool within Drone2Map primarily used to check the GPS accuracy of images?
It stitches images together based on GPS and GCP data
What Drone2Map does to handle the processing of multiple images?
A 3D representation that includes structures like trees and buildings
What is a “digital surface model” (DSM) output in Drone2Map?
Automatically identified points where images overlap
What is a “tie point”?
Overlapping images from different angles
What is the type of data is essential for creating 3D models in Drone2Map?
To enhance GPS alignment and spatial accuracy
What is the purpose of using Ground Control Points (GCP’s) in drone mapping?
Use Ground Control Points (GCP’s)
What is used to ensure accurate GPS alignment in your imagery?
Digital Surface Model; it provides elevation data including buildings and vegetation
What is “DSM” and why is it useful?
To add detailed surface textures over the mesh for realistic visualization
What is the main purpose of a textured model?
Set the project name and file location
What is the first step when starting a new project in Drone2Map?
It processes images to create 3D models and DSMs
What is the function that the “3D mapping” template provide?
For quick, low-resolution previews during field operations
What is the use of the “Rapid” processing option?
A collection of 3D points generated from overlapping drone images
What is a point cloud in the context of Drone2Map and how is it generated?
Point clouds capture discrete 3D points, whereas meshes connect these points to create surfaces
What is true when comparing point clouds and meshes?
Review the Quality Report for processing errors
What must be completed before exporting a map in Drone2Map?
60-80%
What is the percentage of overlap is recommended when capturing drone images for Drone2Map?
Import the GCP file before starting image processing
What is the step necessary to include Ground Control Points in a Drone2Map project?
Data output that is best for accurate measurements of surface elevation and slope in Drone2Map
What is a Point Cloud?
Applying detailed image textures over 3D meshes
What is a textured model improve the visual experience in Drone2Map?
Click “Run” in the processing tab
What is the action must you take to start processing the images?
Measurement Tool
What is the tool that allows users to measure distances and areas within a map?
A network of connected triangles formed from point clouds
What is the description of a mesh in Drone2Map?
