Flight plan to generate best DSM and DTM of dense vegetation

Hi,

In case I want to generate both DSM and DTM from pix4dmapper of a dense vegetation. Which flight plan should I use, is it the double grid plan,

or it is sufficient to use the normal grid with at least 85% frontal overlap and at least 70% side overlap?

Thanks

Hi @beatriceimmanuel25,

I would recommend you to do a double grid mission(70% side and 75%front overlaps) or a single grid with 85% front and 85% side overlap. The most important is to capture the image with an angle between 10º and 35º (0° - the camera is looking down).

Thanks for you information @Kapil_Khanal,

If I use parrot bluegrass with camera position as shown below, is that okay?

Thanks

Hello,

In that case, the angle should be fine.
