Benito River Network in Equatorial Guinea

September 1991 vector dataset representing the Benito River in Equatorial Guinea, created for the African Elephant Database. The data was produced through cooperation between the European Communities, Elsa Wild Animal Appeal, and UNEP/GRID. It contains 12 arcs and 1 polygon, projected using Miller Oblated Stereographic at a 1:1,000,000 scale.

Use Cases

• Analyze river network topology using FNODE# and TNODE# columns to model connectivity.
• Calculate river segment lengths using the LENGTH column for hydrological modeling.
• Identify the Benito River features by filtering on the ROAD-CODE column where value equals 5.
• Map the river's spatial extent using the coverage boundary coordinates (Xmin, Xmax, Ymin, Ymax).

Strengths

• Contains 12 arcs and 1 polygon with explicit topology.
• Spatial boundary is defined with specific coordinate extents.
• Documented projection (Miller Oblated Stereographic) and source scale (1:1,000,000).

Limitations

• Very small dataset with only 12 river arcs.
• Data is from 1991 and may not reflect current river courses.
• No coordinate system is defined within the coverage file.
