Trap Grounds [Introduction] [Conclusion]
The additional measurements and the original GPS data were combined
and converted
into a new area map made up of primary colours. It charts the accessible, inaccessible,
and the temporarily flooded parts of the land as recorded.
A simple computer programme was produced to count the total colour
values for the red,
green and blue pixels. From this data the different areas were calculated, the
higher and
lower estimates of accessibility provide the margin of error.
Table of Results:
| Colour | Accessibility | Pixel Count (sq.m) | Percentage | Average | ||
| Higher | Lower | Higher | Lower | |||
| Red | Inaccessible | 8363 | 11486 | 34.6% | 47.5% | 41.0% |
| Green | Accessible | 13994 | 10876 | 57.9% | 45.0% | 51.5% |
| Blue | Accessible (flooded) | 1817 | 1817 | 7.5% | 7.5% | 7.5% |
| Total | 24174 | 24179 | 100% | 100% | 100% | |
| Total Accessible | 15811 | 12693 | 65.4% | 52.5% | 59.0% | |
Total area of accessibility = 59.0% with a margin of error of 6.5%
In other words, about 60% of the area is accessible.
