Landcover - GIS Data of Surrounding 1552.5 Acre Circle
Description
Data set contains GIS derived landcover classes of land types which surround the plot.
GIS Orthophotos from summer 2015 were used.
Total area quantified for each plot is 1552.5 acres.
Usage
landcover
Format
A data frame with the following variables:
siteID: id of the site
transectID: id of the transect
crop: acres of crop land within the 1552.5 acre circle. Almost always this was corn/soybeans.
grass: acres of grassland within the 1552.5 acre circle. This could include pastures, roadsides, field edges etc.
woody: acres of wooded land within the 1552.5 acre circle. This could include single trees, forests, shrubs, etc.
developed: acres of developed land within the 1552.5 acre circle. This includes any man made, non natural structure, i.e. roads and buildings.
barren: acres of non vegetated land within the 1552.5 acre circle.
shadows: acres of shadows within the 1552.5 acre circle. The true landcover of these acres are unknown due to shadows.
water: acres of surface water within the 1552.5 acre circle. This could include lakes, streams, water treatment facilities, or any standing water.
water_shadows: acres of land which were either water or shadows within the 1552.5 acre circle. Water/shadow differences could not be determined.
water_barren: acres of land which were either water or barren within the 1552.5 acre circle. Water/barren differences could not be determined.
water_grass: acres of land which were either water or grass within the 1552.5 acre circle. Water/grass differences could not be determined.
barren_shadows: acres of land which were either barren or shadows within the 1552.5 acre circle. Barren/shadows differences could not be determined.
Protocol
The center of each plot was determined.
From that center point a circle of radius 1.41km or 0.88miles or total area of 1552.5 acres was drawn.
Within the area of the circle GIS tools were used to quantify the landcover type for each major landcover group variable listed in this dataset.
