Four Mile Canal Terracing and Sediment Trapping TV-18 2010 Photomosaic Data

The Louisiana State Legislature created the Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) in order to conserve, restore, create, and enhance Louisiana's coastal wetlands. The restoration plans developed persuant to these acts specifically require an evaluation of the effectiveness of each coastal wetland restoration project in achieving long-term solutions to arresting coastal wetland loss. This data set consists of digital data describing the photomosaic data for the Four Mile Canal Terracing and Sediment Trapping for the year 2010. Color-infrared aerial photography is acquired and scanned on a photogrammetric scanner that produces a high-resolution image in Tagged Image File Format (TIFF). Each frame is then orthorectified and mosaicked to produce a seamless image.

路易斯安那州议会设立了海岸湿地规划、保护与修复法案（Coastal Wetlands Planning, Protection and Restoration Act，简称CWPPRA），旨在保护、修复、营建并改善路易斯安那州的海岸湿地。依据该法案制定的修复计划明确要求，需对每个海岸湿地修复项目在长期遏制海岸湿地流失方面的实施成效开展评估。本数据集包含2010年四英里运河梯田改造与沉积物截留项目的影像镶嵌数字数据。该数据集采用彩色红外航空摄影技术，通过摄影测量扫描仪完成扫描，生成标记图像文件格式（Tagged Image File Format，简称TIFF）的高分辨率影像；随后对每一帧影像进行正射校正与镶嵌处理，最终生成无缝拼接影像。
