I'm a newbie in GIS and for a project I need to create a shapefile given some points in lat/lon. I have been following this tutorial: https://community.pyramidanalytics.com/t/q5tk8w/creating-a-shapefile-using-latitude-and-longitude-coordinates and it's OK for polygons but I need some lines to be curved.
My data is described given vertices and circles, like this: 3400N 02500W; 3000N 02000W; 3139N 01725W from this point following an arc of a circle 100 NM centred on 3304N 01621W up to 3130N 01545W... and then it continue giving the points of the vertices of the polygon.
(There are other curved parts as well, described like the above part, but I think with one example I'd be able to do the others).
How can I solve this?
