Setting maximum dimension of exported orthomosaic

[johnlionas]

I am processing a set of photos from consecutive spots of a specific area with a python script. The processing involves photos alignment and creation of a dense cloud, a mesh and an orthomosaic. When I export the orthomosaic in a tiff file using GUI, I have the option of setting the maximum dimension in a lower value so that I can produce a considerably smaller file. Specifically I change the value from 4096 to 1024. However, it seems that I do not have this option in exportOrtomosaic python function. Is there a way I can change the resolution of the exported file using the python script?

Hi John !

Here is the solution :

Hello mikeb,

You can use the following methods related to orthomosaic to calculate the require export resolution:
chunk.orthomosaic.width
chunk.orthomosaic.height
chunk.orthomosaic.resolution

So if you need to export the orthomosaic using max-dimension = X, then I think you can use the following:

Code: [Select]

dx = dy = max(chunk.orthomosaic.width, chunk.orthomosaic.height) * chunk.orthomosaic.resolution / X
