751217 Description

North Dakota Intensive Test Site 1966 (751217)

The objective of this experiment was to provide a data set which can be used as an intermediate level of extrapolation between data collected from contolled experimental plots at field research stations and data collection by satellite scanners. The intensive test site represents a 5 by 6 mile area over commercial fields. The major crop in this intensive test site is winter wheat. Other crops in the site include grass, oats, rye and safflower along with some fields with no cover (bare soil).

Data were collected by a helicopter mounted Field Spectrometer System (FSS). The FSS system is based on a S191-H spectroradiometer. Data were collected for 6 lines running E-W across the test site. The FSS spectral data consists of .02 um wide bands from 0.4 to 1.1 um, .05 um wide bands from 1.1 to 2.4 um and 0.5 um wide bands from 8.0 to 14.0 um. The spectral data collected over the site are processed into two different formats. One format represents all individual observations collected over each field (termed single scan data) and the other format represents the average of all similar scans within each field (field averaged data).

The FSS data includes:

     - Bidirectional reflectance factor data
     - 70-millimeter boresight color photographs
     - Flight logs
     - Supporting agronomic, meteorological and atmospheric observations.
