Extract values from tiff

JoaoPinto — Mon, 20 Dec 2021 15:51:27 GMT

Hello Everbody,

I georeferenced a Tiff, but after this, i found a problem with extracting the values (quoted points).

Any solution to extract the quoted points from the tiff?

I leave an image below with an example(red circle) of what I want to extract, but the values are many.

best Regards

two options

or if it is because they are closely spaced then you will need to use one of the other extraction tools

Heads-up digitization could be your fastest option here.

Are you saying you have a tif with the values as written text from a scanned map and you want to extract those text values to points with numeric values?

I don't think that is feasible. I agree with @JayantaPoddar you might have to digitise manually.
