GM in need of help knocking some rust off

AS a player I have been in many games and as such have seen GMs use great maps for towns. buildings inside & out as well as great dungeon maps; I'd love to learn where these GMs are getting such great maps. I have searched Roll20 & the web with very little success on finding great maps either I'm looking in the wrong places or using the wrong key words. Please some one help me obtain great maps I can use for my games

There are a number of possibilities. The GM may have drawn the map himself (or herself) The map (or map tiles) may be from the Roll20 Marketplace, purchased by your GM The map may have been created in a tool specifically for that purpose, such as <a href="http://pyromancers.com/dungeon-painter-online/" rel="nofollow">http://pyromancers.com/dungeon-painter-online/</a> The map may be from a publication like Wizards of the Coast's Dungeon Magazine The map was created from assets on the web, possibly combining multiple sources into a single map

I've also pulled maps from video games via screenshots. It can be tricky to line up the perspective correctly and get it sized for the game, but less work than drawing it myself.

I do Google image searches for: rpg maps rpg city maps rpg dungeon maps etc That seems to always find me something 95% of the time close to what I'm needing, and I tweak it from there. If not I find a blank map from that and add what I need, or use a random dungeon gen and edit it.

Also, RPTools' Map Tool is a simple enough map builder that lets you export the finished product as a JPG file.

campaign cartographer is worth every penny, it comes with a overland map maker, city map maker, and dungeon maker(square or hex). There are great tutorials on youtube for it as well. Once you learn how to use it, you can make very professional looking maps quickly. I have tried all the free ones, and they are mostly junk compared to CC. Other than that I use Gimp(free) for a lot of stuff. Making letters with rustic looking paper or vellum, environment pictures, etc. Other advise: <a href="http://fantasynamegenerators.com" rel="nofollow">http://fantasynamegenerators.com</a> <a href="http://donjon.bin.sh/" rel="nofollow">http://donjon.bin.sh/</a>

Forgot to mention donjon thanks Ken, I love that site, I use it for most my dungeons. Play with it for about 5 minutes to get what I want, then throw it in photoshop replacing white with floor texture, and grey with stone texture and turn it into this..10 minutes total. <a href="http://i.imgur.com/bRuuTAj.jpg" rel="nofollow">http://i.imgur.com/bRuuTAj.jpg</a> Lot less time making a dungeon, then go about filling it with items/decorations and monsters. If I need a dungeon for the next day, using donjon and photoshop I can have a huge one up and ready in 1-2 hours. (pluss the hour of adding dynamic light walling in roll20 :P)

If you're pro with imaging software, Photoshop and GIMP are great choices. If you're pro with CAD, CC is a great choice. If you're neither, MapTool is a great choice, although I export as PNG and convert in Photoshop for file size.

Another good way to create dungeons is simply using the tools inside roll20, even if it's a little more gimmiky. you can, for instance, cover the hole bape with a floor tile you liken, than using the polygon/line tool to draw the dungeon itself. than turn on fog of war and cover the "outside" of the lines, and you have it. If you're a supporter or mentor, you can copy all the lines you have created (first group them all toghether) and then paste it in the dynamic light layer, and this way you can skip the fog of war gimmiky of covering the outside parts. here is an example:
