Nigeria Vertical Aerial Photography For Stereoscopic Mapping

1:10000 scale vertical aerial photography scenes of Nigeria provide overlapping imagery for stereoscopic 3D viewing. The archive is stored as color photographic negatives and can be supplied in digital or photographic formats. The National Remote Sensing Centre (NRSC) collected this data, with the last recorded update in 1991.

Use Cases

• Create topographic maps and contour lines using overlapping 60% along-flight-line and 25% cross-flight-line imagery for stereoscopic photogrammetry.
• Analyze historical land use and land capability changes from 1:10000 scale color photographic negatives for environmental studies.
• Support civil engineering and transport planning projects with large-scale vertical aerial photography for site assessment.
• Investigate boundary disputes or public inquiries by providing detailed aerial evidence of specific areas via cover searches.
• Assess forestry, mining, quarrying, agriculture, and water resource management from high-resolution vertical aerial scenes.

Strengths

• Imagery adheres to the RICS Specification for Aerial Photography Issue III, ensuring standardized quality.
• Photographs offer 60% along-line and 25% cross-line overlap, enabling stereoscopic 3D viewing and precise measurement.

Limitations

• The dataset's temporal coverage is stale, with a last updated date of 1991, limiting contemporary analysis.
• Specific quantitative details like total row count, file size, and available geographic extents are unknown.
