title: Purdue Agronomy Farm Winter Wheat (791806)

description: &lt;p&gt;The purpose of this experiment is 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, 46, and 92 kg/hectare), and three disease treatments (resistant cultivar, susceptible cultivar, and susceptible treated with fungicide) with three replications in a randomized complete block design. Measurements of reflectance and radiant temperature of the wheat canopies were made with the Exotech 20C spectroradiometer system and the Exotech 100 Landsat band 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 University Buildings Demolition, Construction Images, November 2014, POTR Building Camera 2

description: &lt;p&gt;[[Video(http://www.youtube.com/watch?v=c-MM006ycq8)]]&lt;/p&gt;

&lt;p&gt;Purdue&#39;s campus landscape continues to change with the construction of new buildings and the remodel of old buildings. In 2012 the Engineering Administration Building (ENAD) and the iconic Heat and Power Plant-North (HPN) were targeted for demolition to make way for the construction of the Active Learning Center (ALC); a building with offices, collaborative spaces and classrooms with an emphasis on new instructional models. The Purdue University Lyles School of Civil Engineering capitalized on a key opportunity for education and research. Five cameras were installed to capture images from the demolition of the Engineering Administration Building and the Power Plant, to the construction of the Active Learning Center. The images from 3 fixed cameras situated on the Mathematical Sciences Building (MATH) and the Potter (A. A.) Engineering Center (POTR) can be accessed and used for educational and research purposes.&lt;/p&gt;

&lt;p&gt;Representative time lapse videos were created from these three cameras for each month of the project. The time lapse videos created from these images - 08:00 to 18:00, 7 days a week in each month - are accessible here: http://dx.doi.org/10.4231/R70P0WXD.&lt;/p&gt;

title: Purdue Agronomy Farm Corn Cultural Practices (791803)

description: &lt;p&gt;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;3 Planting Dates (May 2, 16, and 30)&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;

&lt;p&gt;The test took place in 1979. 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).

title: Purdue Agronomy Farm Corn Moisture Stress (791801)

description: &lt;p&gt;Differences in moisture availability account for much of the variation from year to year in corn yields. This experiment was a limited study of the effects of deficits in plant available moisture on the spectral characteristics of corn canopies. Three levels of stress were to be established when the corn reached approximately one meter height: none, moderate, and severe. The corn was grown on sand beds, unlain by perforated pipe for rapid drainage. Varying amounts of water can be applied to the plots to provide different levels of available moisture.&lt;/p&gt;

&lt;p&gt;Spectral measurements were to be made with the Exotech 20C and PRT-5 systems at weekly intervals, along with the standard agronomic and meteorological measurements. However, due to an unexpected nutritional problem associated with use of a new sand, only a limited number of measurements were made of this experiment.&lt;/p&gt;

&lt;p&gt;The test took place in 1979.&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).

title: Purdue Agronomy Farm Corn Nitrogen (791802)

description: &lt;p&gt;Nitrogen fertilization is one of the primary factors responsible for the increased yields in the United States in the past 15 years. Four levels of fertilization, 0, 67, 134, and 202 kg/hectare, providing a range from distinctly deficient to abundant have been selected from a long term fertilization experiment. The specific objectives of the experiment were to (1) determine the threshold of spectral detection of nitrogen deficiency and (2) determine kind and magnitude of changes in reflectance and thermal response as a function of level of nitrogen nutrition. Three replications were used.&lt;/p&gt;

&lt;p&gt;Measurements were made at approximately 10 day intervals throughout the growing season with the Exotech 20C spectroradiometer over the 0.4 to 2.4 mu m wavelength range. Radiant temperature of the canopy was also measured. In addition to the standard agronomic data (leaf area index, etc.) leaf nitrogen and chlorophyll concentrations were determined. Also, leaf reflectance measurements were made on several dates.&lt;/p&gt;

&lt;p&gt;The test took place in 1979.&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).

title: Iowa Intensive Test Site 0893 (791237)

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 controlled 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 first 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;
