Spot heights for the Wet Tropics Bioregion (WTMA)

This dataset contains point features depicting spot heights for the Wet Tropics Bioregion. \n\nThe SpotHeight-250K dataset was sourced primarily from the 1:250 000 scale National Topographic Map Series (NTMS) and the Royal Australian Survey Corps Joint Operation Graphics (JOG) map reproduction material (repromat).\n\nThis dataset consists of a 25 MB shapefile containing 134,007 point features.\n\n*Accuracy*\nHorizontal accuracy is at 90% of well-defined detail within +/- 125m of true position. The dataset has an attribute accuracy of 100%.\n\nData reproduced with permission of Wet Tropics Management Authority\n\nThis metadata was prepared for the e-Atlas and is not authoritative.
