Do you know you can use custom settings and powerful cloud computing for all your mapping projects?

Add ground control points to improve both global and relative accuracy, or apply processing areas to highlight the area of interest of your Pix4Dmapper cloud projects, and more…

Pix4Dmapper hybrid solution


Offering both desktop and cloud processing to generate mapping outputs such as digital surface models (DSMs), 2D maps and 3D textured mesh, Pix4Dmapper is one of the first hybrid solutions in surveying and mapping industries. By “hybrid,” we do not just refer to a selection of using it on desktop or cloud, but the complementary of both in the same workflow.



As a professional user, you may prefer processing images using a desktop software because you can have more control of the project. Take one of the most used features – adding ground control points (GCPs) for example, Pix4D Desktop interface allows you to easily import and edit those points. You can easily view errors and adjust the point location on corresponding images in real time, which you cannot do with the cloud.


However, with the desktop version, you may also find it complicated when sharing the output with your client. In the past decades, geospatial data were mainly used by people in the industry. Due to the popularization of drones, the acquisition of aerial images is easier and much more efficient, making the generated output accessible to almost everybody. You no longer need to download tons of unfamiliar software just to open and visualize georeferenced maps or models. Now, you simply send a link to clients so they can view the entire project with all the annotations you made in a browser.


Since both of our desktop and cloud solutions have their strong points, we see no reasons forcing our users to choose one over the other. In other words, with Pix4Dmapper hybrid solutions, you are able to process projects with customized settings and share them out easily.


Why go hybrid?

Apply custom settings to achieve better-quality results


The Pix4Dmapper hybrid solution allows you to apply preferred settings to cloud processing. You can indicate the image scale and targeted number when finding image key points, adjust the weight of imported geotags and choose the corresponding calibration method. These customized settings have a direct impact on the quality and efficiency of your cloud-processed projects. For example, by increasing the image scale, assigning a larger targeted number of key points or using geotag-assisted searching, you force the cloud processing to find more features in difficult projects. By changing the scale, density, and minimum matches in point cloud densification, you can generate a better-described digital surface model.


Improve both global and relative accuracy of powerful cloud computing


The hybrid solution is especially important if you want to improve the accuracy of your cloud projects. All you need to do is to create a desktop project and run initial processing (easier to find the right locations for marking points), import your ground control points (GCPs) or check points and mark them on corresponding images, or add manual tie points (MTPs) to improve some problematic regions. Once you reoptimize and upload the project to the cloud, the marked points will be taken into account for processing, and the accuracy of them will be displayed in the quality report. With the accurate ground truth, you will obtain your mapping outputs with the centimeter accuracy as you expected. With the accurate ground truth, you will obtain your mapping outputs with the centimeter accuracy as you expected.


Clip areas of interest for efficient processing


Another common use of our hybrid solution is when you have a huge amount of images but would only like to process and share a part of it with certain clients. You can simply define a processing area in Pix4Dmapper Desktop and upload the project to cloud. Pix4Dmapper Cloud will generate all outputs only within the region you indicated. This allows efficient processing and highlights the area of interest to your clients.




Since Pix4D Desktop is offering so many advanced control options, the key question is, how practical it is to sync the desktop project with the cloud? Since Pix4D Desktop version 3.2, uploading images and project settings from desktop to the cloud becomes 10 times faster, which takes only a couple of minutes to upload a project of 150 images. The high-speed uploader smoothens the hybrid workflow and completes the solution.
