Upon Return

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 to rank each photo as "Really Good," "Just OK," or "Not Useful."
• Second, use the Knitter 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, you can upload images to a Public Laboratory server and email 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.
