We first generate a set of locations (i.e., points(x,y)), randomly. Then we assign for each point a number showing the angle of a line being centred at that point. The criteria for the length of lines ...
I am looking automate the creation of a polar grid shapefile (polygon). I am currently creating this in a many-step editing process, starting from a concentric buffer. Here is how I think I should be ...
I want to write an algorithm that creates a polygon inside a hole made by a set of other polygons. It's something like a flood fill and it's like the "boundary" tool in Autocad. The image shows an ...
I have a shapefile containing arcs representing the path travelled by a truck spreading fertiliser onto a farm. Let's say I know the spread width is 30m, i.e. the truck can spread fertiliser 15m ...
Given a set of coordinates, How do we find the boundary coordinates. <== Figure 1 Given the coordinates in the above set, How can I get the coordinates on the red boundary. Boundary is the polygon ...
I have several thousand irregularly shaped polygons in a shapefile. I want to be able to split each polygon into three areas, and to specify what the size of those areas (they sum to the previous ...
