Hi @**[Raúl
](https://community.pix4d.com/t/6098/comments/360000254143)**
Since the cloud is running the stable, you will not see it from the processed folders. In case you are interested in seeing the values, you may re-optimize the project using the desktop preview.
There are some cool surveys here, with very creative ways to show the Pix4D logo.
Here’s my survey of a natural channel design in Oakville, Ontario: https://cloud.pix4d.com/pro/project/258797/map?shareToken=59c4c7c377fc4139839018bc0ea36e0a

Good luck to everyone!

Attached is the link to our project. We had to do a little impromptu painting but we got it in there.
This site will look very different very soon. Proposed development!

Hola.
Quisiera saber cuales son las fechas de inicio y cierre de esta convocatoria.
Saludos desde Colombia!!!
Here is my submission for the contest. Thanks for the opportunity to have some fun with this challenge.

Good Luck Everyone
@Angélica María Leon Pedraza, the deadline is Thursday, March 15 (23:59 CET). You can learn more about the challenge at the top of this page.
Hello,
I’m a bit late to join the race, but I will try anyway, the weather forecast is good for tomorrow!
As I’m not familiar with processing in the cloud, could you explain the best way to edit the raycloud with Pix4Dcloud? Should I download the results, edit with P4D desktop and upload it back?
Thank you,
Julien
Hi everyone! Greetings from Philippines. Here is our entry for the challenge. We had used 2 rolls of tissue paper for the logo and few stones preventing it to be blown. We are also proud to feature the landscape map of our province- Leyte, Philippines. Phantom 4 Pro was used.

@Brandon
It’s there something funky going on with your DSM. The height difference in the DSM cougth my eye and the I measured height of one of the cars and I’m pretty sure that none of them are over 6m tall 
The terrain looks pretty flat but accoding to DSM there is 100m height difference from lowest point to top of the tallest tree
@vijayaraghavan R @Julian Krick @Brandon Egelhoff @Matt Gurr @Eco Farmi: wonderful projects! and creative Pix4D logos!
@Julien Lieb: You can create a project on desktop (adapt processing options, add MTPs, or GCPs,…) and then upload to the Cloud for processing with Project > Upload Project Files… If you upload through the Cloud interface, standard processing options will be applied (e.g. 3D Maps). However, edits made with the point cloud editing tool will not be taken into account. If you use the Annotation tool (Carve) on desktop and then upload the project, the Carve should be applied on the Cloud as well. Everything Cloud related is documented here. More specific links in point 4. of the “How to participate” section in the original post. Let me know if there are other questions. Good luck!
@jaakko I’m not sure I see what you are seeing in my dsm. On my end everything looks right and the 3D model certainly doesn’t show the cars being 100m. I did use ground control to bring the whole surface up to ground. So al elevations should be at msl. Would be courious to see the bust and how to fix it.
@Brandon
I meant that the cars are out of proportion (over 6m in height). Either you have big cars in the states or your DMS is messed up 
It looks OK visually but the scale seems to be messed up. There must be some weird foot to meter conversion that is the source of this.
And the DSM shows the lowest point over 100m under the highest point but visually your terrain looks pretty flat.
Here’s the explanation:

Note that mapping trees is notoriously difficult, and the area of interest was only the orchard.
In fact, here is a the area of interest from a closer flight path of 20m:

Dan, there must be some overlap or MTP issues because looking at the 3D model shows all sorts of mis-alignment. Yes trees are hard to map with any detail but they shouldn’t affect the alignment of the scene…you may need more MTPs or add a Processing Area. You can look at Jason’s project and see that lower detail doesn’t mean mis-alignment…just an FYI to improve the project.
Jaakko and Brandon, I see the same scale issue as well…that car is not 45 feet long :) I wonder if there is some feet to meter issue?
Eco and others, be sure to check your 3D model for mis-alignment, not just the orthomosaic. It is great to see the point cloud finally from Pix4DCloud and it is quite revealing on areas that just aren’t processed correctly or not flown correctly. Each project has different requirements so maybe it isn’t an issue but this industry will never gain full credibility until we are as good or better than any other method. This is by no means a negative to anybody here, it is great seeing all sorts of projects and they look good…I have the experience with many customers questioning the accuracy of photogrammetry so it is my goal to help improve this industry.
I tell everybody this…always check accuracy in the point cloud as everything else is an approximation from it. This is also why I don’t care for other “not to be named” software packages that only produces a mesh.
Well hopefully the Cloud gets done with my own project tonight or tomorrow…I cut out half my pictures so it hopefully gets done in time.
What a great opportunity to apply Pix4D skills and knowledge! Here is a novel approach using a “school bus”.
Our project for consideration is here: https://cloud.pix4d.com/pro/project/259386/map?shareToken=4ad14d64815042c5836e21a285f33c2d
#Pix4Dchallenge
Hey Everyone,
We are excited to enter our submission for the surveyors challenge! We decided to use the DJI Phantom 4 Pro copter flown with the DJI Ground Station Pro flight app. Two main flights were generated in a grid pattern, the first with complete nadir image acquisition, and the second with the camera slightly angled. The two flight plans were perpendicular to each other, and took approximately 1 hour to acquire images. The copter was flown with a maximum speed of 4 mph, in order to reduce image blur due to movement. The flight altitude was ~165ft AGL, and ~125ft AGL respectively. Image overlap was planned for 80% forward and side overlap, or greater. Approximately 400 images were acquired for the initial area comprised of less than 10 acres.
This project was flown entirely for this competition, and if you look closely in the gravel parking lot you can see the Pix4D logo. Since this is a surface model competition, we tried to make the logo “POP” in the DSM by using spray foam in order to write each letter. You can notice it in the point cloud, but the online DSM symbology will not detect the minor changes to display it.
Survey precise Ground Control Points were used to georeference the 3D model and orthophoto. We only used 4 ground control points collected with a Trimble R6, as this project is for demonstration purposes only. Typically we would set double this amount of control (with redundant shots on each control panel) with additional check shots in between in order to verify the accuracy within Pix4D, as well as external point cloud software’s.
There are a few cars that moved during the duration of the flight, causing some noise in the parking lots. Currently we do not have any leafs on our hardwood trees since its still brisk outside, therefore the landscaping trees are not generated as smooth as they would if there was actual matter on them to be mapped. Typically we appreciate when this happens as our goal is to map the surface of the earth, and not the vegetation that exists on it!
Working with large buildings such as this church in Fuquay Varina (North Carolina, US) means that we have to generate and fly missions with detail in order to recreate the site in 3D for inspection or topography surface generation. We typically fly and process at least two sites a week for either volume calculations, topography surface models, or high resolution orthophoto generation. Pix4D has been a critical part of our workflow for over two years, and we look forward to how it will continue to open new doors for the construction and engineering fields.

Anyways, thanks for the opportunity and we look forward to participating in future competitions, and hall of fame submissions.
