Land Cover Map Along the Inuvik-Tuktoyaktuk Highway Corridor.

This land cover map was developed mainly for permafrost mapping along the Inuvik-Tuktoyaktuk Highway (ITH) corridor. Along the ITH corridor, vegetation changes from forest in the south to typical arctic tundra in the north. Vegetation conditions play important roles affecting permafrost, and they also are indicators of snow and subsurface conditions, which are critical for permafrost as well.本土地覆盖图主要为开展因纽维克-图克托亚图克公路（Inuvik-Tuktoyaktuk Highway，ITH）沿线区域的永久冻土填图工作而编制。沿该公路沿线区域，植被类型从南部的森林逐步过渡至北部典型的北极苔原。植被状况不仅对永久冻土具有关键影响，同时也是积雪与地下环境状况的指示指标，而此类要素同样对永久冻土至关重要。
