DRAPE_2024_RASTER

The Digital Raster Acquisition Project Eastern Ontario (DRAPE) 2024 imagery acquisition was part of a Geospatial Ontario coordinated project. This aerial project is part of a five-year plan (2023-2027) to acquire high-resolution, leaf-off/low leaf imagery of settled areas across the province. DRAPE 2024 was acquired in the spring of 2024 , under the best conditions possible to achieve cloud free, snow free, ice free, smoke free and leaf off/low leaf captures. The orthophotography has a pixel resolution of 16 centimetres and is accurate within 45 centimetres on the ground. Time of Capture: March 12th - May 31st 2024 Coverage: 35,993 square kilometres Canopy Coverage: Leaf-Off/Low-Leaf Resolution: 16 centimetre Bit-depth: 8-bit Number of Image bands: Four band (RGBN) Accuracy: Within 45 centimetres on the ground at 95% confidence. Format: GeoTIFF (and compressed GeoTIFF)东安大略数字栅格采集项目（Digital Raster Acquisition Project Eastern Ontario, DRAPE）2024影像采集项目，系安大略地理空间（Geospatial Ontario）统筹协调项目的组成部分。该航空影像项目是安大略省2023-2027年五年规划的组成部分，旨在采集全省定居区域的高分辨率落叶/低植被覆盖航空影像。DRAPE 2024项目于2024年春季开展采集作业，为获取无云、无雪、无冰、无烟雾且符合落叶/低植被覆盖要求的影像，全程选用最优气象条件实施。该正射影像的像素分辨率为16厘米，地面定位精度可达45厘米以内。 采集时段：2024年3月12日至5月31日 覆盖范围：35993平方千米 冠层覆盖状态：落叶/低植被覆盖 影像分辨率：16厘米 位深度：8比特 影像波段数：4波段（RGBN） 定位精度：95%置信度下地面误差不超过45厘米 数据格式：GeoTIFF（含压缩GeoTIFF格式）
