Upon return from your balloon mapping trip, you'll want to:

* First, select the clearest, most straight down images of your desired area:
  * you can sort them one at a time on your computer, or 
  * have multiple people use [MapMill](http://publiclaboratory.org/wiki/mapmill) to rank each photo as "Really Good," "Just OK," or "Not Useful." 
* Second, use the [Knitter](http://cartagen.org/maps) or a desktop program like Adobe Photoshop to georectify the images and stitch them into a map.

###Uploading to MapMill###

Using an FTP/SFTP program like [Filezilla](http://filezilla-project.org/), you can upload images to a Public Laboratory server and email [team@publiclaboratory.org](mailto:team@publiclaboratory.org) once your transfer is complete. We'll add your images to the MapMill.org site and you can start sorting.

**SFTP information**

_You must use the more secure SFTP protocol, not normal FTP_

Server: **upload.publiclaboratory.org** 
Username: **mapmill**
Password: **grassygrassy**

_Place pictures in a folder (not zipped, please) named with the date, the site name, and your name, like ’2011-8-15-missisippi-longbeach-jeff’_

**It's very helpful if when you submit folders, they are labelled in this format and each set is a single folder containing only JPG images.**
