Shoot-out (2006)

Analysis of Soils by Diffuse Rectance

There have been a couple of inquiries about using the 2006 data set in publications. Click here to get the official acknowledgment needed to appear in any publication that uses the data set.

The data for the 2006 IDRC shoot-out session is availabe below, as are the datasets from earlier IDRCs. You can find the instructions and rules for this event by clicking here - 2006 Shootout Rules. The data set is available in many formats. The data can be downloaded by selecting the appropriate link below. These files have been zipped, but they are still quite large.

In the MATLAB, NSAS and JCAMP formats, missing constituent information is indicated by a value of -1 replacing the missing data. In the Unscrambler format, missing constituent data is indicated with the normal Unscrambler symbol of lower-case "m" replacing the missing data.

Additionally, the Unscrambler, JCAMP and MATLAB formats have the spectral data from 350 to 2500 nm in 1 nm increments, while the NSAS format has the spectral data from 400 to 2498 nm at 2 nm increments. Please note that the data is in units of Reflectance. NOTE - The units on the NSAS file indicate absorbance only to allow the Vision software to read the file. The spectral data is ALL in REFLECTANCE.

Matlab - 62MB

Unscrambler - 36MB

NSAS - 17MB

JCAMP-DX - 35MB

Also, the signal to noise ratio information below is provided. The details for this are as follows. The instrument was warmed up for 4 hours. Repeated scans of the white Spectralon reference were collected approximately every 30 seconds. This was repeated for approximately 5 days in a row. The S/N was scaled such that the sum(S/N)^2 = 1. The exact number of repeated scans is not known.

S/N data - 200KB in Excel format.

Parameter Description file - 16KB in Excel format.

8/19/2006 - Now that the 2006 conference is complete we have the validation results available for download. This is in Excel - Validation File.

For some years the instructions that originally accompanied some of the data sets are missing. If anyone has a copy of a missing set of instructions related to any of the prior Software Shoot-outs listed below, please contact Howard Mark (Email).
