TVA Surveying History Planimetric & Topographic 7 1/2’ Quadrangle Cooperative arrangement with USGS 896± Quad sheets Photogrammetry Techniques created and mastered by TVA & USGS Aerial Photography archive

TVA Surveying History Aerial Photograph Finished Quad Map Who knew that the modern photogrammetric processes started between a cooperative arrangement between NGS and TVA in Chattanooga? Finished Quad Map

Planimetric & Topographic TVA Surveying History Planimetric & Topographic This new photogrammetric process would be used to map the entire TN Valley. New reservoirs would be built, flooding would be mitigated, and the area would be able to economically prosper. Only graduates from top colleges would be employed in these new processes. In just a few short years these same techniques would be put to global use.
