Are basic map files exportable?

Hi all, I am new to the site and forum - just wanted to pose a couple questions before I spend too much time on here. I have a vast game world I designed when I was younger (when there was no such thing as new editions of AD&D), probably several books worth of material in total. Some of my maps and dungeons are massive in size (largest was more then a full pad of graph paper, easily more then 50 sheets in total) and there is no way its all going to fit on here even with a subscription. So i'm wondering, is it possible to compose the basic map/floor plan of any single given structure/dungeon etc and export it off the site? Or am I better off looking for another program to do this kinda thing? Just something where I can import scanned maps of square graph paper, snap to square grid or hexagonal grid and use zoom functions etc. The basic map editor on here works nicely for that kinda thing, but I see no option to save or export files. I'd like to put up some of my material on here but initially just looking to digitize the maps / content so I can have (and manipulate) them on PC. Its all still on ye old sheets of paper and will probably take me months worth of work just to transfer the info/maps onto PC. Never done anything concerning D&D on PC before and i'm a complete novice with the site and scanning etc., please be gentle. :)

Most people use. Gimp. Or other map tool to make a flat image  to then upload to roll20

Does Gimp have a build in grid system you can build on top of?

No grid in Gimp. To be honest, if you're looking for a program that allows images to "snap" to corners and midpoints, I'd recommend Inkscape. Much like Gimp, it's free. Plus you can lay out your own grid.
Ah great, thanks for the tip i'll look into that next :)

Gimp has a viewable grid but it does not print. There are ways to make a printable grid in gimp but that is not roll20 specific.
I would build the image without a grid and setup the grid thur roll20 page settings amyway

i agree with lordmage. If you are planning to eventually use those maps in roll20, you're better off not having a visible grid on the map, and using roll20's grid.

There are some great dungeon-building programs out there, too. I won't recommend any of them here, since it's OT to discuss products outside of Roll20 too heavily, but a web search can turn up many of them, some free or with powerful demo versions.

Back to the original poster's questions that are roll20 related: Damon M. said: Hi all, I am new to the site and forum - just wanted to pose a couple questions before I spend too much time on here.

There is no official method to export anything you create in roll20 but there are a few methods you can use to get an image from roll20 to your pc. The main way many people use is a screen capture of sections of maps they built then stitch them together before uploading them back to roll20. I usually build any images that I use in gimp then upload them to roll20. This lets you have a copy on your pc so that if something happens you have a backup.
lordmage said: I would build the image without a grid and setup the grid thur roll20 page settings amyway Problem is (for the larger maps) that the content is drawn on old graph paper (square grid) - and all the paper sheets are taped together for any given map piece / level. Some maps are 4 or 5 feet square, maybe more. So the grids don't completely line up spacially (grid system was imperfect - not to mention my joinery of tape), and some are crumpled and have creases etc. I won't be able to accurately restitch them digitally without having a grid system to manipulate them and work on - with sizing and snapping tools. But this only works as a blueprint to draw on anyways.  Doesn't matter if the final map has a grid on it to me, but it has to be accurate to use on a grid system. I managed to scan and import a small 3 page castle map onto roll20 here yesterday and use the sizing and snapping tools to align things properly on the grid - but it will only function as a blue print to draw a real map on, and it did work well. Rather a daunting task considering the amount of material tho. No idea if this is really the best way to go about transferring the large graph paper maps onto PC, dissecting them for scanning in the first place is a job in itself. I don't think digital pics of the large dungeon maps will work either because, i'm guessing, the edges will distort in size the further away they are from the camera / on the edges of the field of view. But the grids don't line up properly on them anyways. I wonder if just redrawing them by hand on PC would be faster. I did also look at some of the map/dungeon editors online but didn't see anything (for free) that seemed to suit my purposes, but again i'm a complete novice here. Even for transferring the larger maps into a dungeon builder it would be nice, if not required, to have a large, accurate map (grid-wise) to import, but again maybe it would be faster just to redraw them by hand with a dungeon builder, Inkscape or Gimp, then transfer the finished maps onto roll20. In regards to the scale of things, when I was designing my stuff back when.. I was always disappointed at the limitations of a single, square page of paper to confine my imagination on. Not saying that things have to be big to be good.  But I wanted some dungeons/architecture to be vast, sprawling, labyrinthine areas that my players could literally get lost in, for days (gnomish delves, dwarven kingdoms, or legendary dungeons that exist for hundreds or thousands or years should be Vast, some of them anyways). I still find this square-box characteristic evident in MMORPGs to this day; areas and architecture stuck into a square box of 3D space. And I still find it disappointing. Tho the best content transcends this concept completely, regardless of size. Anyways, my goal is to transfer my content into digital format first, have backup versions, then take a few adventures and stick them on roll20 - and see where that goes.
