Lat/Long: 39, -93.7 Observer: Rauch
Active Since: 2009  
   

Site Description:

Site is located in a rural area of mostly cultivated land with sparse woodlands, mostly in riparian areas. About 100 acres of low density Christmas trees on property.

Hive consists of 2 deeps, colony is a one year old Buckfast package. Plan to requeen in Spring of 2009.

Scale is an old platform type, 17 x 22 in., 500 lb capacity, leveled on wooden base and exposed to weather.

Forage is primarily Black locust in spring, white clover in summer, with soybeans in some years.

MODIS Subset Data (from the ORNL DAAC)
Red dots are the average of all pixels with acceptable quality (see landcover extract below for area covered).
Blue dots are the center pixel only (point is not plotted if the pixel is of unacceptable quality).

 

NDVI

The Normalized Difference Vegetation Index (NDVI) is the ratio of the  difference between visible (red) and infra-red (IR) wavebands to the sum of these bands. 

NDVI = nir - red / nir + red


 NDVI provides an indication of the amount and vigor of vegetated  surfaces. 

 NDVI has been widely used with multiple generations of satellite data.

EVI

 The Enhnaced Vegetation Index (EVI) is a more complicated combination of wavebands compared to the more widely used index, NDVI.  The advantage of this newer index is improved sensitivity in high biomass regions and reduction in atmospheric influences.
where,
pNIR = NIR reflectance
pRed = red reflectance
pBlue = blue reflectance
C1 = atmosphere resistance red correction coefficient
C2 = atmosphere resistance blue correction coefficient
L = canopy background brightness
G = gain factor

The MODIS sensor on the Terra satellite platform provides us with 16-day composite measures of NDVI/EVI throughout the year.  NASA distributes MODIS data from many of their distributed data centers.
