Point density tool outputs-units

SophieKay — Wed, 01 May 2019 10:29:22 GMT

Hello all,

I am trying to examine point density of where tropical cyclones form. My output cell size is 100 km^2 (I am looking at the Central Pacific) and my outputs in the legend come out as values such as 2.5.

Does this mean there are 2.5 storms that form within each 100 km2 grid cell? I'm just looking for some clarification, as I also have values of 0.75 also. This leads me to believe my interpretation is incorrect and that a division has occurred?

Thanks in advance!

Relying on an answer from someone else won't help. Make sure that your results make sense with respect to your cell size, any scaling and your input values

Thanks for your reply. I did take a look at those before posting, but still couldn't figure it out I'm afraid, hence the post.

That would depend on the options your have specified.

Even 'defaults' have their implications and require interpretation.
