City of Melbourne 3D Textured Mesh (Photomesh) 2020

3D textured mesh (photomesh) representing all physical features (e.g. buildings, trees and terrain) across City of Melbourne. The 3D textured mesh is provided in object file format (.obj) and is accompanied by material (.mtl) and image texture (.jpg) files.The data has been split into a series of tiles covering the entire municipality. An index file (Tile_Index.kml) is included to indicate the geo-spatial location of each tile. To position the mesh in its real world location, use the origin coordinates found in the metadata file (metadata.xml).The 3D textured mesh is provided in different levels of detail, as indicated in the file name of the .obj filename. The levels of detail vary from L13 (lowest level of detail) to L20 (highest level of detail).Capture Information- Capture Date: May 2020- Capture Pixel Size: 7.5cm ground sample distance- Map Projection: MGA Zone 55 (MGA55) - Vertical Datum: Australian Height Datum (AHD) - Spatial Accuracy (XYZ): Supplied survey control used for control (Madigan Surveying)ContentsThe download is a zip file containing compressed:- Object files (.obj)- Material files (.mtl)- Image textures (.jpg) - Metadata (.xml)- Tile index (.kml)Preview Data:For an interactive sample of the data please see the link below (WebGL browser required - Google Chrome recommended).Photomesh 2020 - SLPK (arcgis.com)Photomesh 2020 - OBJ (arcgis.com)Usage:Through the download an use of this data you agree to the licensing and disclaimer conditions.While all due care has been taken to ensure the data of this website is accurate, current and available please note: · there may be errors or omission in it· there may be occasions where the data is not available and/or the website will be unavailable.

本数据集为覆盖墨尔本全市所有实体地貌（如建筑、树木与地形）的三维纹理网格（photomesh）。该三维纹理网格以对象文件格式（.obj）提供，配套材质文件（.mtl）与图像纹理文件（.jpg）。数据已被拆分为覆盖整个市政辖区的多个瓦片，附带索引文件（Tile_Index.kml）用于标注各瓦片的地理空间位置。若需将网格定位至真实世界坐标，可使用元数据文件（metadata.xml）中记录的原点坐标。该三维纹理网格提供不同细节层级，具体层级可从.obj文件名中识别，细节等级范围从L13（最低细节层级）至L20（最高细节层级）。
