Agisoft Metashape: SfM, dense reconstruction, and DSM generation.
Detailed Explanation
Agisoft Metashape is a software tool used in photogrammetry that focuses on three main functionalities: Structure from Motion (SfM), dense reconstruction of 3D models, and the generation of Digital Surface Models (DSMs).
- Structure from Motion (SfM) is the process of taking multiple images from different angles to create a 3D model. Metashape automatically identifies common points in the images and uses them to calculate the 3D coordinates of the features captured in the photographs.
- Dense reconstruction refers to generating detailed and high-resolution 3D models from these photographs, allowing for fine detail and accurate representation.
- Digital Surface Models (DSMs) represent the Earth's surface along with any objects on it, such as buildings and vegetation. This is crucial for applications that require detailed terrain analysis.
Examples & Analogies
Imagine you are trying to create a detailed scale model of a town using photographs. By taking pictures from various locations and angles, Agisoft Metashape acts like a puzzle solver, identifying pieces of the model (or features in your town) and fitting them together until you have a complete 3D representation of the town, complete with houses, trees, and roads.

Pix4Dmapper: UAV photogrammetry and GIS integration.
Detailed Explanation
Pix4Dmapper is another leading software in the field of photogrammetry that specializes in using Unmanned Aerial Vehicles (UAVs), or drones, for capturing aerial imagery. It allows users to create 3D maps and models from this imagery.
- One of the powerful features of Pix4Dmapper is its integration with Geographic Information Systems (GIS). This means it can combine and analyze geographic data, enhancing mapping accuracy and providing valuable insights for various applications like agriculture, construction, and urban planning.
- Users of Pix4Dmapper benefit from its automated processing capabilities, which simplify the workflow from image acquisition to mapping, making it more accessible for various industries.
Examples & Analogies
Think of Pix4Dmapper as a digital architect who uses drone-captured bird's eye views of a construction site. Just like an architect would combine blueprints and geographical data to design a building, Pix4Dmapper combines images and GIS data to build accurate 3D models, helping planners visualize projects before they break ground.

DroneDeploy: Cloud-based mapping and modeling platform.
Detailed Explanation
DroneDeploy is a cloud-based software platform that enables users to conduct aerial mapping and modeling using drone technology. It provides tools for creating 2D maps, 3D models, and other analysis features.
- The cloud-based nature of DroneDeploy means that users can access their data anytime and anywhere, facilitating collaboration among teams across different locations.
- It is typically used in construction, real estate, agriculture, and environmental monitoring, due to its simplicity and the ability to produce detailed maps and models efficiently.
Examples & Analogies
Imagine DroneDeploy like an online service that allows you to order a personalized map of your backyard, complete with flower bed designs, tree placements, and lawn features. Instead of sending someone to draw it for you, you simply upload drone images, and the platform processes and generates the map for you, accessible from your computer or mobile device.
