title: South Dakota Intensive Test Site 1687 (781227)

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 intensive test site represents a 5 by 6 mile area over commercial fields. The major crops in this intensive test site are spring and winter wheat. Other crops in the site include rye along with some fields with no cover (bare soil). This experiment is a continuation of 761227 and 771227.&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;light logs&lt;/li&gt;
 &lt;li&gt;Supporting agronomic, meteorological and atmospheric observation&lt;/li&gt;

title: Purdue University Buildings Demolition, Construction Images, December 2014, POTR Building Camera 1

description: &lt;p&gt;[[Video(http://www.youtube.com/watch?v=2MtSIre0uUQ)]]&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 Soybean Row Direction (791810)

description: &lt;p&gt;The objective of the experiment is to determine the effect of rows and row direction, variables in the area of cultural practices, on the reflective response of a soybean canopy as a function of azimuth and zenith sun angles. The design of the experiment involved 11 plots. One plot was planted in east-west and north-south rows 25 cm wide to obtain, at later growth stages, a canopy with negligible row effects. A second plot was bare soil, providing an opportunity to monitor the reflectance of the soil background of the soybean plots. The remaining nine plots were planted in soybeans with 76 cm wide rows with the following azimuthal directions: 90-270, 105-285, 120- 300, 135-315, 150-330, 165-345, 180-360, 210-030, and 240-060 degrees. The row directions were selected to maximize the probability of obtaining data during the morning hours when cloud conditions are more favorable for data collection than in the afternoon. Reflectance data were acquired at 15 minute intervals throughout the day on three days, representing three canopy growth stages.&lt;br /&gt;
Data analysis involves mathematically modeling the effect of combinations of sun azimuth and sun zenith angles on the reflectance from a row crop of soybeans. The experiment design permits the effect of sun angles to be analyzed independently.&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 Instrument Altitude (791811)

description: &lt;p&gt;The object of the experiment is to determine how the canopy reflectance varies as a function of height above the crop and, particularly, what minimum height is needed to acquire repeatable reflectance measurements. Data were acquired on three canopies, mature corn planted in 76 cm rows (field 52) mature soybeans planted in 96 cm rows with 50 to 70% ground cover (field 898) and mature soybeans planted in 76 cm rows with 100% ground cover (field 899). The canopies provided scenes with a range of row effects from pronounced rows to no obvious rows. Data were acquired at 10 heights hanging from 0.5m to 10m above the canopy. At each height 12 reflectance data points were acquired at 15 cm intervals in the direction perpendicular to the rows by moving the spectrometer along a horizontal board. The data analysis involves determining how the variance of the data obtained at each height changes with height. This analysis will provide the information necessary to place error bounds on reflectance data acquired at a particular height.&lt;/p&gt;

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

title: Purdue Agronomy Farm Soil Background (791807)

description: &lt;p&gt;The purpose of this experiment was to determine the effects of soil background (soil color, soil moisture, soil roughness) on the spectral response of corn. The treatments were:&lt;/p&gt;

&lt;ul&gt;
 &lt;li&gt;2 surface moisture levels (moist and dry)&lt;/li&gt;
 &lt;li&gt;2 surface tillage conditions (rough and smooth)&lt;/li&gt;
&lt;/ul&gt;

&lt;p&gt;Two replications were used in a randomized complete block design. Spectral reflectance measurements were made with a Landsat band radiometer (Exotech 100). Radiant temperature and overhead color photographs of the canopies were obtained simultaneously with the reflectance measurements. Oblique color photographs were also obtained. The agronomic measurements of the plots included crop growth stage, percent soil cover, plant height, leaf area index, plant biomass, and surface soil moisture and condition. Grain yields were measured at harvest time.&lt;/p&gt;

title: Purdue Agronomy Farm Corn Leaf Blight (791805)

description: &lt;p&gt;The purpose of this experiment was to investigate the effects of a non-systematic fungus disease, southern corn leaf blight (Helminthosporium maydis), on the multispectral reflectance and radiant temperature of corn. Southern corn leaf blight is an example of a non-systematic fungus disease capable of significantly reducing the photosynthesis capacity of corn. The specific objectives of the experiment were to determine the relationship of disease severity level to the spectral characteristics of corn. The factorial treatments included 2 Hybrids and 3 Leaf Blight Treatments (non, early and late inoculation). The early and late inoculation provided two different levels of disease severity at any given measurement date. The experiment was conducted using a randomized complete block design with two replications. After the disease became established (about July 1) measurements of reflectance and radiant temperatures were to be made with the Exotech 20C and PRT-5 sensors at weekly intervals until maturity. In addition to the standard agronomic characterization of the canopy the degree of infection (loss of green leaf area) was measured. Inclement weather in August and loss of one of the hybrids due to poor germination severely limited data collection on 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).
