Finer Resolution Observation and Monitoring of Global Land Cover 10m (FROM-GLC10)¶

This work and the paper was designed with an aim to classify 10-m resolution images acquired in 2017 with a sensor on board a different satellite. We examined through the 10-m resolution map, FROM-GLC10, and compared it with our 2017 30-m global land cover map, FROM-GLC30. We found while the results are comparable the 10-m map did provide more spatial details. Although an overall accuracy comparable to the 30-m resolution data was achieved, the actual accuracy of the 10-m resolution map can only be properly assessed with test samples collected from the 10-m resolution data.

About FROM-GLC¶

Global land cover data are key sources of information for understanding the complex interactions between human activities and global change. FROM-GLC (Finer Resolution Observation and Monitoring of Global Land Cover) is the first 30 m resolution global land cover maps produced using Landsat Thematic Mapper (TM) and Enhanced Thematic Mapper Plus (ETM+) data.

Data preprocessing¶

The datasets were downloaded and a MODE pyramiding scheme was applied owing to the fact that these are classified datasets. The RGB values were provided by the authors and these were converted to hex code for creating a palette. The sample script also takes into consideration remapping the values to provide a more continuous mix max distribution.
