Service Description: This web map shows two unsupervised classification for Landsat 5 satellite images with three bands: 1, 4, and 5 of the electromagnetic spectrum. The data was classified first with Iso Cluster Unsupervised Classification. Then a majority reclassification was applied before applying boundary cleaning. Finally, the pixels counts were transformed into hectares by multiplying pixel counts by the spatial resolution (30x30=900) which yielded square meters, which later divided by the number of square meters per hectares (10,000). The end resulted revealed 25% shrinkage of Lake Pyongyang over 30 years.
