Laguerta explained that the additional one kilometer from the seven-kilometer extended danger zone is a buffer distance
We merged well buffers around each individual well into a single polygon per buffer distance
and state to account for overlapping buffers within states due to higher well densities, in order to avoid duplication in population allocation.
To calculate the minimum buffer distance
for each wetland, a GPS waypoint was taken at each wetland and subsequently plotted using ArcGIS 10.0 (ESRI, Redlands, CA).
Each field can be divided into fumigated blocks that each have a related buffer distance
and buffer zone meeting all requirements.
The results in figure (2.A) are showing the buffer distance
of three hundred meters around the tube wells.
While the efficacy of the five-metre buffer distance
between vehicles travelling at 80km/h is drawing diverse reactions from motorists, what has garnered unanimity is the decision by the Dubai Police to use radars to catch culprits.
Using circular buffers of a quarter mile, half mile, one mile, and three miles we examined the number of schools with >4 pCi/L test results within each buffer distance
category of a residence with >4 pCi/L results.
"Stay under 400 feet, stay 5 kilometres away from an airport, so that keeps you away from any aircraft that might be flying, planes or helicopters, staying more than 30 metres away from people or property keeps a safe buffer distance
from people who could get injured from your machine, and always keep your machine in line of sight so you can see where it is, keep it under control at all times," he said.
The turbines have been located at a recommended buffer distance
from the mains gas pipeline that runs through the site, that being 1.5 times the hub height."
Out-of-the-box, the Buffer tool allows users to specify the buffer distance
in map units, the buffer selection layer, and whether or not the attributes of those features within the buffer will be displayed.
Similarly, if a car slows for 3 seconds, or just long enough to force the car behind it to slow too, the car behind must delay resuming speed long enough to rebuild buffer distance
. At 60 miles (or about 100 km) per hour, cars are supposed to maintain 6 car-lengths.
BUFFER encloses point and line features within a polygon and allows the user to define the buffer distance
between the feature and the polygon edge.
