Hydrography: lakes, rivers, streams, swamps, rapids, falls. Transportation: roads, trails, railways, bridges, airports/airfield, seaplane. Culture: buildings, urban development, power transmission line, pipelines, towers. Toponymy: place names, water feature names, landform names, boundary anchorages geographical names.
