I am new to julia and currently using ArchGDAL. Currently, I want to compute a convex hull for a lot of points. When I using AG.convexhull, and save the result to a shapefile using GeoDataFrames. When I open the shapefile with QGIS, the shapefile is still the orignal points. The result should be a convexhull polygon (only one polygon).
Here is the code:
coords = zip(rand(10), rand(10))
table = DataFrame(geom = hull)
Also, does anyone know how to read shapefile(points) and compute convex hull for shapefile directly?
Any help on this? Thanks in advance!
