[jts-dev] Minor error in the STRtree javadoc

[Chamin Nalinda Lokugam Hewage <chamin.lokugamhewage@xxxxxxxxxxxxx>]

hi devs, 

while using JTS to make R-tree, 

I noted a minor error in the documentation. 

the depth() method states, that it returns the size of the tree

instead, it returns the depth or the number of levels. 

kind regards!
