Landsat Ii Digital Data Analysis and Mt Tarawera Vegetation
نویسنده
چکیده
Digital data collected by Landsat II satellite were used to produce a vegetation map of Mt Tarawera, Rotorua, New Zealand. The accuracy of this map, when checked in the field, varied for each class of vegetation; low stature and cover vegetation were more reliably classified than tall forest. The average probability of a resolution unit being correctly classified (with 95% confidence limits) was 65% when strict vegetation class definitions were used, and 88 % when more flexible definitions were adopted.

Vegetation succession on Mt Tarawera, Rotorua, New Zealand, a recently erupted volcano, was studied. Field data from 70 plots were collected and analysed by a clustering algorithm. The plots formed an altitudinal and successional series which included bare scoria, herbfield, mixed hardwood, scrub, kamahi forest and tawa forest. Because of the differential effects of the 1886 eruption, different...
