LBA-ECO LC-01 Hydrography, Morphology, Edaphology Maps, Northern Ecuadorian Amazon

Map images depict hydrographic, morphologic, and edaphic features for the northern Amazon Basin in eastern Ecuador. Hydrographic data are available at two scales from 1:50,000 and 1:250,000 topographic maps generated in 1990 and 1993, while morphological and edaphological data were digitized from a 1:500,000 map published in 1983. The dataset is distributed as three compressed ZIP files.

Use Cases

• Analyzing river network patterns and drainage density based on hydrographic map layers.
• Studying landform evolution and soil-landscape relationships using combined morphological and edaphological data.
• Creating base maps for ecological or hydrological modeling in the northern Ecuadorian Amazon region.
• Comparing landscape features across different spatial scales (1:50k, 1:250k, 1:500k).

Strengths

• Provides multi-scale hydrographic data from 1:50,000 and 1:250,000 source maps.
• Integrates three distinct feature types—hydrography, morphology, and edaphology—for a single geographic region.
• Originates from a recognized scientific organization (NASA).

Limitations

• Source maps are dated, with the most recent topographic sources from 1993 and morphological data from 1983, limiting current applicability.
• Metadata completeness is low, with column names, row counts, and specific file contents unknown.
• Conflicting 'last updated' dates exist between platforms (1993 vs. 2026), creating uncertainty about data currency.
