A panel illustrating alien vegetation land cover change (A) and native vegetation land cover change (B) with classes including expansion, loss, and stability for the 1990-2020 timeseries.

This dataset was used to produce land cover change maps for Figure 3.5 as part of a master's thesis titled- Repeatable methods for classification of alien and native vegetation in the Montane grasslands.Three data entries are included: (1) r script- for coding and visualisation (2) GeoTIFF with four generalised land cover types during 1990-2020 for alien vegetation and (3) GeoTIFF with four generalised land cover types during 1990-2020 for native vegetation.This dataset illustrates the changes that occurred in both alien and native vegetation as four generalised land cover changes (i.e. Other land cover changes, loss, expansion and stable) between 1990 and 2020, using a harmonised Landsat time series.Date of data collection: February 2020Location of data collection: Blyde River Canyon Conservancy and its surrounds, in Mpumalanga/Limpopo Provinces, South Africa.

本数据集用于制作题为《山地草原外来与本土植被分类的可重复方法》的硕士论文中的图3.5土地覆盖变化地图。本次数据集包含三类数据条目：(1) 用于编码与可视化的R脚本（R Script）；(2) 包含1990—2020年外来植被四类广义土地覆盖类型的地理标记图像文件格式（GeoTIFF）文件；(3) 包含1990—2020年本土植被四类广义土地覆盖类型的地理标记图像文件格式（GeoTIFF）文件。本数据集基于经过统一协调处理的陆地卫星（Landsat）时间序列数据，展示了1990年至2020年间外来与本土植被的四类广义土地覆盖变化类型，即其他土地覆盖变化、消失、扩张与稳定状态。数据采集日期为2020年2月，采集地点位于南非姆普马兰加省与林波波省的布莱德河峡谷保护区及其周边区域。
