Oh! you know to fly a drone… and what do you do with the data that you collect? [Parte II]

Now we are here again, for those who missed the previous post I leave here the link to the first part, for everyone else, then I leave a small review of programs for the treatment of the data collected with a drone, here we go:

PIX4D:   pix4d

The most popular software for the processing of data collected via a Drone, obviously because it was one of the first and I don’t know if it would be very wrong if I say that the first. In fact, sensefly attached it inside the package when you buy one of its drones.

We can say, of the program… which is very complete, you have so many options that it may even be difficult to handle. It is a program that works on local, so prepare a powerful team to process the data that you collect.

It may be little intuitive and somewhat tedious in carrying out your first projects without prior training. That if, and this is welcomed, the results can be exported to a large number of formats and extensions to be able to continue working with the images in other programs CAD, ERDAS and ARCGIS…

In terms of outcomes, measurements on the orthophoto are correct. Again compared to measurements in orthophotos of the Government of la rioja, the measures have an error lower than 3%, which, taking into account that the project has become quickly more than is acceptable.

To give you an idea of the power of this program, sensefly mapping the Matterhorn with this program, and the truth, les was not bad…

As I have already mentioned, a thing so only you can do with the most powerful software…

Agisoft Photoscan:  Agisoft

This software is not so exclusive to treat data collected from drones, is used to create models in 3D buildings or objects. In fact, you have a version for mobile and take pictures in 3D. The main application in drones is the obtaining 3d models of remote objects and make measurements on the model.

The drawbacks, a program installed locally so you need a decent computer for processing, the photos must be of quality and have to be taken concrete form, if not the model will not be well and therefore the measurements do not. Generate PDFs of models in 3D.

I leave a few examples with the same pictures that I’ve done the rest of tests and the example of the pdf in this link 3D: 3D project

Maps Made Easy: mapsmadeeasy

I found this application during the development of this post. Like Dronedeploy, it is a service in the cloud. Operational it, upload photos that you got with your drone and then the orthophoto which take measurements is generated. NVDI and 3D models can be generated. The difference with Dronedeploy is that you need to work more, you have to enter by hand at least 7 GCP (ground control points), the process is very simple.

The results are made to wait a bit since you upload photos to the cloud, but are satisfactory. You have several options when it comes to exporting your orthophotos and to working with them in other programs. One of the drawbacks, are the units, they are Anglo-Saxon system, I have not managed to change them.

The program has an option of “flight planner” and an exclusive pilot for apple map, there are no Android, know if a link is necessary to load the plan in the drone or you can do it via the network as in UgCS.

Here you have some examples:

This is the “dashboard” of the application:

And the result and their exportable formats:

Summary:

Finally, along with those that appear on the 1st part of this post, these are programs that I have tried, as you can see in the table below all have their good and bad, things like everything in life… I encourage you to try them and you decide based on the work that you are going to do and then tell it us all of them have free trial versions.

I leave you with the listing, if you click on the icon will take you to the page where you can prove it or even purchase the license that best suits your needs:

Dronedeploy

Features: Application in the cloud, easy to use and good results.

pix4d

Features: Application in local, need for powerful equipment for processing data, on the other hand, perhaps the most powerful of the four as well as the most difficult to handle.

Agisoft

Features: More focused on generation of 3D models but also program is popularise get orthophotos and measurements on them. It requires more technique in obtaining photos. Also application to install in place with what is required

mapsmadeeasy

Features: Application in the cloud. Its use is very simple and she is will be explaining the step by step process. The way the results is really clear and is easy to work with the orthophotos.

See you!!
