General / Band designations in Metashape 1.5 for RedEdge camera photos

« on: November 22, 2019, 12:24:17 AM »

I am working with a MicaSense RedEdge camera with band designations as indicated below: 

Micasense RedEdge
Band 1 - Blue (center wavelength = 475 nm)
Band 2 - Green (center wavelength = 560 nm)
Band 3 - Red (center wavelength = 668 nm)
Band 4 - Near Infrared (center wavelength = 840 nm)
Band 5 - Red edge (center wavelength = 717 nm)

In Metashape when working with a raster calculator tool (Tools --> Raster Transform) to standardize reflectance values, Metashape has designated Band 4 - Red Edge and Band 5 - NIR.

Does Metashape recognize which is which, and has just re-ordered them (e.g., based on wavelength), or have they been switched?

Thank you.

Bug Reports / can't write pyramid data

« on: September 12, 2019, 10:02:56 PM »

Dear Forum,

I'm experiencing repeated "can't write pyramid data" errors when attempting to create an orthomosaic from a DEM.  The general conditions are:

Running the process locally on laptop with 32 GB RAM and 1 TB solid state hard drive with 293 GB of free space

2775 images, 10 ground control points, 1,073,203 tie points,  DEM 36802x44405, 1.57 cm/pix, images are RGB (.jpg, .dng) from a Ricoh GR2 camera

Agisoft Metashape Professional Version 1.6.2 build 7838 (64 bit) with a shared license within US Department of Interior (i.e., computer looks to DOI server occasionally to confirm the license, but all processing is done locally)


First time ran with 113 GB free drive space and error was cannot write pyramid data, not enough disk space
Second time ran with 293 GB free drive space and error was cannot write pyramid data, not enough disk space
Third and fourth time ran with 293 GB free drive space and error was cannot write pyramid data.
The job always fails in about an hour, after working to orthorectify sets of 28 photos at a time

The job is a recurrent analysis based on monthly flights over a study site.  The last .TIFF orthmosaic file that was created was only 9.3 GB.

Any insight would be appreciated.
