Hi, I'm (extremely) new to GIS and related technologies. I am looking to get started but don't know where to begin. I need something to allow me to interpret map data, specifically road. I.e. If my long. and lat. are xx and yy, I would like to know what happens at xx + 1 and yy. Is this possible? I also need something that does not require an internet connection, so the data must be pre-loaded. Does technology like this exist?
Thanks in advance for the help.
