Hi R users, I want to calculate Thiessen weights to compute areal rainfall from number of point measurements. I am using R and thanks to some previous question in the same topic, I got to know that I can usedeldir. But the problem is my boundary polygon is not a rectangle; it's an irregular polygon (it's a catchment boundary derived using ArcGIS). But in deldir the boundary can only be a rectangle. Are there any other packages where I can calculate Thiessen weights of an area covered by an irregular boundary?
Given below are my measurement points (meas_points) and coordinates of a (simplified) boundary polygon(boundary) > meas_points X Y[1,] 415720 432795[2,] 415513 432834[3,] 415325 432740[4,] 415356 432847[5,] 415374 432858[6,] 415426 432774[7,] 415395 432811[8,] 415626 432762 > boundary x y[1,] 415491 432947[2,] 415269 432919[3,] 415211 432776[4,] 415247 432657[5,] 415533 432657[6,] 415781 432677[7,] 415795 432836[8,] 415746 432937 Any help is really appreciated.
