#Spectrometry Projects#
**Spectral Workbench open source spectral analysis**

**Goal:** spectrum pattern matching to identify oil contamination
** Links:** http://github.com/jywarren/spectral-workbench
**GPLv3**

###Project: import open spectral databases###
**Description:** Determine which spectral databases can be used in an open source manner (such as perhaps the HITRAN and ASTER datasets) and import them, tagging them with their source and relevant metadata. Focus on near-infrared, visible, and ultraviolet ranges. 
** Links:** https://github.com/jywarren/spectral-workbench/issues/54
**Prerequisites:** Ruby/Rails, familiarity with open data licensing and database parsing/scripting
**Difficulty level:** easy
**Mentor:** Jeff Warren (jeff@publiclaboratory.org)

#Map Projects#
**MapKnitter open source image rectification and GIS**
**Goal:** spectrum pattern matching to identify oil contamination
**Links:** http://github.com/jywarren/mapknitter
* GPLv3

###Project: optimize and improve high-resolution stitching interface###
**Description:** This could take the form of several ideas/approaches -- from [caching the warped images as dataURLs in the canvas element](https://github.com/jywarren/mapknitter/issues/13) to speed up interactivity, to [implementing the Client Zoom feature in the most recent OpenLayers](https://github.com/jywarren/mapknitter/issues/75).
**Prerequisites:** JavaScript/Prototype/Canvas element, Ruby/Rails
**Difficulty level: ** medium
**Mentor:** Jeff Warren (jeff@publiclaboratory.org), Stewart Long (stewart@publiclaboratory.org)

###Project: Clashifier open source image classification. abstract Classifiers class to make different classifiers more pluggable###
**Goal:** identify wetlands species and/or oil contamination
**Links:** http://github.com/jywarren/clashifier
* GPLv3
**Description:** Some structural changes are necessary to allow people to develop and add new classifiers to the system. It should be as easy as having a "classifier.classify()" function which accepts an RGB (or more colors) pixel value, or perhaps an image and x,y coordinates. Some of this work has been started in the /lib/ directory, but it will require some architectural changes.
**Links:** https://github.com/jywarren/clashifier/issues/4
https://github.com/jywarren/clashifier/issues/3
**Prerequisites:** Ruby/Rails, some familiarity with classification algorithms like naive bayes or cartesian, or anything else
**Difficulty level:** medium
**Mentor:** Jeff Warren (jeff@publiclaboratory.org)

###Project: add annotations layer to Mapknitter###
**Description:** This could include adding polygonal overlays to highlight regions, adding notes, and linking discussions/data directly into maps.  
**Links:** https://github.com/jywarren/spectral-workbench/issues/89
**Prerequisites:** JavaScript/Prototype/Canvas element, Ruby/Rails
**Difficulty level:** medium
**Mentor:** Jeff Warren (jeff@publiclaboratory.org), Stewart Long (stewart@publiclaboratory.org)

###Project: georeferencing in Mapknitter without base image data###
**Description:** investigate and implement different methods of georeferencing images besides overlaying on existing aerial data.  GPS, ground-target, or EXIF-embedded data could all be used.
**Links:** https://github.com/jywarren/mapknitter/issues/64
https://github.com/jywarren/mapknitter/issues/10
https://github.com/jywarren/mapknitter/issues/65
https://github.com/jywarren/mapknitter/issues/73
**Prerequisites:** JavaScript/Prototype/Canvas element, Ruby/Rails
**Difficulty level:** medium
**Mentor:** Jeff Warren (jeff@publiclaboratory.org), Stewart Long (stewart@publiclaboratory.org), Ned Horning (horning@amnh.org)

###Project:  Align and analyze overlapping visible and near infra-red images###
**Description:**  A utility to process large numbers (dozens or hundreds) of pairs of visible and infra-red images, including those taken by users with matched visible and IR cameras. The utility could automate a subset of the processes below. It could be based on the experimental multispectral features of MapKnitter, with a focus on analysis and NDVI. Such a utility could greatly improve the quality, consistency, and usefulness of the NDVI maps made by Grassroots Mappers.
* Align pairs of overlapping visible and near IR photographs
* Crop the result to the area of overlap
* Compute NDVI for each pixel of the layered image and produce a third layer of the NDVI values.
* Modify the assignment of colors to the NDVI values
* Downsample the NDVI layer by averaging (e.g., blocks of 4 to 256 pixels) to account for alignment error
* Interactively display the NDVI value for mouse-selected pixels or polygons
* Output the NDVI layer (e.g., as jpeg) for aligning with adjacent overlapping images (e.g., MapKnitter) or stitching into a seamless aerial image (e.g., MS ICE, Gigapan Stitch)
**Prerequisites:** JavaScript/Prototype/Canvas element, Ruby/Rails, GDAL and/or ImageMagick/RMagick, familiarity with remote sensing would be nice

#MapMill.org crowdsourced image sorting#
http://github.com/jywarren/mapmill

###Project: shift image storage to Amazon S3###
