options to generate higher resolution of orthograph #705

Closed bingzhang closed 6 years ago

bingzhang commented 6 years ago

Hello:

I have a dataset with 200+ image and total size is 1.5 GB. By default 40 pixels per meter, the output orthograph is around 200 MB. I tried to increase to 70 pixels per meter, the output orthograph size does not increase however a little bit less than the default 40 setting. By using another tool, the output result size is around 1 GB. Is there a way to increase the output size of orthograph, please?

Regards.

It depends on the resolution of your images. If you try to increase the resolution higher than the resolution of your images, then you won't get anything higher. It's possible the other tool is not efficiently handling the orthomosaic. It is also possible that the other tool is processing a larger area. ODM tends to be more conservative around the geographic edges of a dataset, and therefore will construct a smaller orthophoto, despite having the same resolution.
