I have a few projects where I'm plotting various things on a map that's broken down by neighborhood (this, basically). It's looking like I need to make my own shapefile but with absolutely no GIS knowledge of any kind I'm utterly stumped about how to do this. Everything I've found so far relies on expensive proprietary software and technical procedures that are way over my head, it looks like a lot of it even presupposes you already have a shapefile and just need to convert it to a different format.
Is there some way a layman can load up a map of a city and draw their own?
Since apparently there is no way to directly message the staff who locked this: This question is not opinion based. Whether a program exists that allows someone to visually draw polygonal shapes on top of a map and save the result as a shapefile is a question answerable only by objective facts.
