Question 1

I have to work in hilly areas, does Tap2Map have a solution for this?"

Accepted Answer

Yes, Tap2Map is among the few Applications on the market to offer a TERRAIN FOLLOWING option at the moment. This is, on a photogrammetric point of view, the most important option to keep the block images overlappings and thus will allow a better "bundle block adjustement", then a better final product accuracy.

Question 2

Can Tap2Map be used in countries where there is no stable internet access, or in remote areas without 3G signal?"

Accepted Answer

Once installed, the application itself do not really need any internet connexion to work, it's understood that you need to have an internet connexion at least to draw your AOI on an updated map. Then on the field, you can fly your project without internet as far as your get GNSS sufficient number of satellites.

Question 3

Is it possible with Tap2Map to fly a multi-batteries project in order to map an area larger than a single battery endurance?

Accepted Answer

Yes, it’s not a issue for our Tap2Map application. As soon as you use our ”divide area” option, which is based on your battery endurance, the drone will come back to the departure point for you to you change the battery for a new one and restart.
In any case when you interrupt a flight, the application will keep the mission progress and restart the next flight at the place it was stopped.

Question 4

Is it possible to run DJI-Go application in background and start Tap2Map at the same time on my IOS device?

Accepted Answer

We would not recommend to do this. As far as we know it’s not possible for the moment to run 2 applications at the same time on an iOS device, it might be quite annoying for you, but that’s the only way for us to be able to waranty the good functionalities of our Tap2Map application.

Question 5

If I want to take control of my drone during the automated flight, is it possible?"

Accepted Answer

Yes. Tap2Map offers a fonctionnality that allows you to ”pause” the mission and hoover, or land in place, or return to take off point, but you can do this manually.

Question 6

Is it possible with Tap2Map to control the drone camera angle?

Accepted Answer

The camera angle is usualy preset in Tap2Map according to the mission type that you choose, but you always can change the angle in the flight screen to any angle by step of 5º… Except for the ”double grid” mission where you’ll have the choose among the 3 preset camera tilt angles.

Question 7

Regarding the light conditions, what camera settings do you recommend?"

Accepted Answer

This is not a Tap2Map depending question. But we did set the tuning of the camera to ”automatic exposure”. In any case, our application offers you the possibility to access to manual settings.
We cannot recommend a specific setting for photogrammetry, but from our experience if you find a manual test exposure that fits with your needs, keep the same setting for the whole flight, as a mission is generally for a short duration.

Question 8

What do you recommend as forward and lateral overlaps?

Accepted Answer

We do not recommend specific overlaps. Your tecnical choices for this, and the third party software that you intend to use after, is relying on your own knowledge. But we have an opinion about this topic: due to the fact that many drone lenses have a kind of wide FOV, we recommend to stay on the safe side with quite large overlaps (like 70% / 70% as a minimum). But be aware that the overlaps will not be constant due to the terrain variation in elevation … Our interesting feature of Terrain Following option will at least allow to mitigate (or nearly eliminate) the risk to have too weak or small overlaps due to the terrain variations.

Question 9

Can I create a 3D product with Tap2Map?

Accepted Answer

No, Tap2Map is a Flight planning software, it will allow you to collect proper survey grade standard data in order to create 3D maps through a third party processing software.

Question 10

Which cameras/sensors does Tap2Map work with?

Accepted Answer

Tap2Map is adapted to all built in DJI’s sensors types that are offered. We also added the possibility in our development that our customers can configure and use their own sensor that will be mounted on their DJI drones.
Note: In that case, we do not manage the triggering communication between the drone and the owned camera, make sure that it works.

Question 11

Does Tap2Map work with different drones brand?

Accepted Answer

Tap2Maponly works with DJI drones.

Question 12

What type of SD Card is recommended?

Accepted Answer

Please only use high-speed SD Card. Do not take the risk to jeopardize your porject to save few money.
