Volume Calculations using QGIS

[@antoniiojosee]

hi, from Brazil! Your video is awesome, your content is super current. One day i will visit India.

Brilliant Brilliant Brilliant greetings from Deutschland haha

Great Explanation 👍

[@geodeltalabs]

Glad you liked it

[@revansiddayyap3925]

I like the way you explain it and i have a request that pls start a tutorial on HEC-Ras or Watergem softwares where there are no recent contents on youtube, I will be waiting for your reply brother and love to learn those softwares from you.

Thank you for this, excellent guide! As I understand it the calculated area in the volume report is a "flat" surface and not the surface area?

I would love to be able to take drone photos and import them to qgis and extract volumetric data the way that I can with other photogrammetry webwares

in here , how to get hill.tif is it dem file

[@sreenathijk2952]

what is pixel value , i didnt understand, can you explain it

The horizontal and vertical length of one grid cell

BUT HOW DID YOU CREATE PIT FILE, THATS THE REAL THING. AND YOU SKIPPED IT ? 😢

[@geodeltalabs]

Hi, no there was no plan to include it in the first place in this tutorial as this focuses only on the volume calculation aspects (hence, the raster dataset is provided for you guys to directly download). As a quick note, there are multiple ways to create a 3D model of a pit, and one of them is to have an array of depth/ elevation points and use a geostatistical interpolation method to develop a raster dataset. More advanced methods would include things like LiDAR scans. I will publish a tutorial on this in a couple of days time so keep an eye out for that :)
