title: Iowa Intensive Test Site 0893 (801237)

description: &lt;p&gt;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 purpose of the experiment is to study the spectral characteristics and separability of corn, soybeans, oats, and pasture as a function of growth stage and cultural practices. The intensive test site represents a 5 by 6 mile area over commercial fields. The major crops in this intensive test site are corn and soybeans. Other crops in the site include grass (pasture) and oats along with some fields with no cover (bare soil). This the second year for an experiment at this site.&lt;/p&gt;

&lt;p&gt;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).&lt;/p&gt;

&lt;p&gt;The FSS data includes:&lt;/p&gt;

&lt;ul&gt;
 &lt;li&gt;Bidirectional reflectance factor data&lt;/li&gt;
 &lt;li&gt;70-millimeter boresight color photographs&lt;/li&gt;
 &lt;li&gt;Flight logs&lt;/li&gt;
 &lt;li&gt;Supporting agronomic, meteorological and atmospheric observations.&lt;/li&gt;
&lt;/ul&gt;

&lt;p&gt;The study took place in 1980.&lt;/p&gt;

&lt;p&gt;The supporting docs include a brief summary of used instruments, a wavelength table (Wavelength_ASCII.txt), reflectance note and reflectance tables (ReflectanceTable206.txt and ReflectanceTableMulti.txt), and file format description (ExperimentDataFormat3.txt). The format description file is in ASCII format in lines of 80 characters.&lt;/p&gt;

&lt;p&gt;This research dataset is part the Field Research Data Library that consists of over 200,000 spectral observations of soils and vegetation that have been collected since 1972 till 1991 as part of the research focused on vegetation and soils at the Laboratory for Applications of Remote Sensing (LARS) located at the Purdue University.&lt;/p&gt;

title: Soil reflectance and soil moisture (tension) study (801601)

description: &lt;p&gt;The purpose of this experiment was to study the relationship of soil reflectance and soil moisture (tension). Fifty-seven samples were selected from surface samples representing 240 representative soil series widely distributed over the United States and supplied to Purdue&#39;s Laboratory for Applications of Remote Sensing (LARS) by the Soil Conservation Service (SCS). See experiment 781701. The 240 samples were selected to cover as large a range of visible spectral properties (colors) as possible. In experiment 781701, reflectance measurements were made of the soils equilibrated to a moisture tension of 0.1 bar. For this experiment, 57 of the 240 samples were selected to represent the range in soil charateristics known to affect reflectance such as iron oxide, organic matter content, texture, etc. Reflectance measurements of these 57 samples were made with the samples equilibrated to several other moisture tension levels . All 57 sample were run at oven dry; 12 of the 57 samples were run at 1/3 bar; 29 of the 57 were run at 15 bar; and 15 samples were run an 10 bar.&lt;/p&gt;

&lt;p&gt;The study took place in 1980.&lt;/p&gt;

&lt;p&gt;File 801601 contains soils data&lt;br /&gt;
File 801602 contains reference calibration data&lt;/p&gt;

&lt;p&gt;Note: The reflectance of 6 soil sample were measured on 8/12/80 at 15 bar. After that time, concern was raised that at least some of the soil samples may have not equilibrated at 15 bar moisture tension. Some of these samples were rerun on 7/17/81.&lt;/p&gt;

title: Purdue Agronomy Farm Corn Cultural Practices (801803)

description: &lt;p&gt;1980 is the second year for this experiment, (see 791803). The objectives of this experiment are to determine (1) the threshold of early season spectral detection of corn, (2) the spectral response of corn as a function of growth and amount of vegetation, and (3) the effect of soil background differences, particularly soil color, on the spectral response and early detection of corn. The treatments were as follows:&lt;/p&gt;

&lt;ul&gt;
 &lt;li&gt;7 Planting Dates (May 7, 16, 22, 29, June 11, 18 and July 2)&lt;/li&gt;
 &lt;li&gt;3 Plant Populations (25,000, 50,000 and 75,000 plants per hectare)&lt;/li&gt;
 &lt;li&gt;2 Soil Types (Chalmers, &quot;darker&quot; and Fincastle, &quot;lighter&quot;)&lt;/li&gt;
&lt;/ul&gt;

&lt;p&gt;A split plot design with two replications was used. Spectral measurements, along with agronomic characterizations of the canopies and surface soil, were made at approximately weekly intervals throughout the growing season.&lt;/p&gt;

&lt;p&gt;The spectral reflectance measurements were made with a Landsat band radiometer (Exotech Model 100). Radiant temperatures and overhead color photographs of the canopies were obtained simultaneously with the reflectance measurements.&lt;/p&gt;

&lt;p&gt;The major agronomic measurements of the plots included growth stage, percent soil cover, height, leaf area index, biomass, and surface soil moisture and condition. Grain yields were measured at harvest time.&lt;/p&gt;

title: Purdue Agronomy Farm Winter Wheat (801806)

description: &lt;p&gt;This experiment was a continuation of the 1979 Winter Wheat Experiment. The purpose was to investigate the effects of disease and nitrogen fertilization on the spectral and agronomic characteristics of winter wheat. There were three nitrogen fertilizer rates (0, 60, and 120 kg/hectare), and three disease treatments (resistant cultivar, susceptible cultivar) and susceptible cultivar treated with fungicide) with two replications in a randomized complete block design. Measurements of reflectance and radiant temperature of the wheat canopies were made with the Exotech 20C field spectroradiometer system and the Exotech 100 field radiometer system at approximately weekly intervals from tillering through ripe stages of development. Agronomic characterizations of the canopies included: leaf area index, biomass, percent soil cover, height lodging, disease severity, leaf nitrogen concentration, and grain yield.&lt;/p&gt;

title: Purdue Agronomy Farm Winter Wheat Disease (801805)

description: &lt;p&gt;The purpose of this experiment was to investigate the effects of disease (rust) on the spectral response of winter wheat. There were two disease treatment levels with three replications. Each plot was 6 meters square. Measurement of reflectance and radiant temperature of the wheat canopies were made at approximately weekly intervals of two replications of the plots from the time the wheat was inoculated with rust until the wheat was ripe. Several observations were made of each plot to study the effects of varying severity levels as the disease spread throughout the plot.&lt;/p&gt;
