General / Re: Export to KML format

« on: March 04, 2025, 01:47:45 PM »

Thank you for your reply.

My client needs a KML file because he has other software that only accepts that format.

I had read about the requirement of WSG84 - but I thought that requirement was met by the geotags from the jpegs captured by his drone.

I tried using an online utility that converts KMZ to KML files, and it produced about a dozen small KML files.  When loaded into Google Earth, it depicts squares in the proper geolocation but with big red "x"s over the squares.

I'm not well informed about KML and KMZ format files.  So I may be missing something obvious and simple to someone who is well informed.

General / Export to KML format

« on: March 04, 2025, 02:33:08 AM »

Hello -

I have a small project.  I have an orthomosaic that I want to export as a KML format file.

The help says I can do this, by choosing the orthomosaic, selecting export, selecting a coordinate system, and then doing the export.

In my version of Metashape, I don't get the option to choose the coordinate system.  And perhaps because of that, the only choice I have is to export in a KMZ format.  I need KML.

Is there a way to do this?

Thank you - Joe Stroup

General / Rolling Shutter questions

« on: March 25, 2024, 09:31:01 PM »

Hello -

I have a couple of questions about Rolling Shutter corrections in Metashape.

First - how does Metashape determine the camera sensor read-out time for a camera?  For example, WebODM has a database of known camera read-out times, or the user can enter the read-out time for the task being processed.  Alternately, Pix4D allows the user to set if the camera sensor is a rolling-shutter - and if so, will calculate the read-out time from the data.

As a note - the camera sensor read-out times reported in the Pix4D quality reports are often wildly different from the actual readout times for a camera.

Second - I'm testing Metashape for models of building where the survey flight path is an orbit.  By stopping the drone at each photo, no rolling shutter correction is needed.  But if the drone does not stop, the the rolling shutter effect will exist - but in the lateral direction.  Does Metashape provide a rolling shutter correction in this case?

Thank you!

General / Metashape on Raspberry Pi 5

« on: March 23, 2024, 04:11:20 AM »

I've had some success running WebODM on an overclocked Raspberry Pi 5 with a 1TB NVMe.

I was hoping to have similar success with Metashape - but I'm getting an error that seems to indicate that the Metashape Linux software is complied for X86 hardware.

Does anyone have any information about this?

Many thanks!
