SYD Landsat raw data v01
收藏资源简介：
## **Abstract** \n\nThis dataset and its metadata statement were supplied to the Bioregional Assessment Programme by a third party and are presented here as originally supplied.\n\n\n\nLandsat TM, and ETM+ data are provided in GeoTIFF for Level 1T (terrain corrected) products, or for either Level 1Gt (systematic terrain corrected) or Level 1G (systematic corrected) products, if Level 1T processing is not available. GeoTIFF defines a set of publicly available TIFF tags that describe cartographic and geodetic information associated with TIFF images. GeoTIFF is a format that enables referencing a raster image to a known geodetic model or map projection. \n\n\n\nThe initial tags are followed by image data that, in turn, may be interrupted by more descriptive tags. By using the GeoTIFF format, both metadata and image data can be encoded into the same file. The Landsat 7 ETM+ GeoTIFF file format is described in detail in the"Landsat 7 ETM+ Level 1 Product Data Format Control Book (DFCB), LSDS-272": http://landsat.usgs.gov/documents/LSDS-272.pdf. The Landsat 4-5 TM GeoTIFF file format is described in detail in the "Landsat Thematic Mapper (TM) Level 1 (L1) Data Format Control Book (DFCB), LS-DFCB-20": http://landsat.usgs.gov/documents/LS-DFCB-20.pdf. \n\n\n\nFor more information on GeoTIFF visit: http://trac.osgeo.org/geotiff\n\n## **Dataset History** \n\nORGANIZATION\n\n\n\nEach band of Landsat data in the GeoTIFF format is delivered as a grayscale, uncompressed, 8-bit string of unsigned integers. A metadata (MTL) file is included with data processed through the Level-1 Product Generation System (LPGS). A file containing the ground control points (GCP) used during image processing is also included. A processing history (WO) file is included with data processed through the National Landsat Archive Production System (NLAPS). Landsat 7 ETM+ SLC-off products processed after December 11, 2008, will include an additional directory (gap_mask) that contains a set of flat binary scan gap mask files (one per band). (Please note that the processing date and acquisition date are not necessarily the same.)\n\n\n\n\\* DATA FILE NAMES\n\nThe file naming convention for Landsat LPGS-processed GeoTIFF data\n\nis as follows:\n\n\n\nLMSppprrrYYYYDOYGSIVV_BN.TIF where:\n\n L = Landsat \n\n M = Mission (E for ETM+ data; T for TM data; M for MSS)\n\n S = Satellite (7 = Landsat 7, 5 = Landsat 5, 4 = Landsat 4)\n\n ppp = starting path of the product\n\n rrr = starting and ending rows of the product\n\n YYYY = acquisition year\n\n DOY = Julian date\n\n GSI = Ground Station Identifier \n\n VV = 2 digit version number\n\n BN = file type:\n\n B1 = band 1\n\n B2 = band 2\n\n B3 = band 3\n\n B4 = band 4\n\n B5 = band 5\n\n B6_VCID_1 = band 6L (low gain) (ETM+)\n\n B6_VCID_2 = band 6H (high gain) (ETM+)\n\n B6 = band 6 (TM and MSS)\n\n B7 = band 7 \n\n B8 = band 8 (ETM+)\n\n MTL = Level-1 metadata\n\n GCP = ground control points\n\n TIF = GeoTIFF file extension\n\n\n\nThe file naming convention for Landsat NLAPS-processed GeoTIFF data \n\nis as follows:\n\n\n\nLLNppprrrOOYYDDDMM_AA.TIF where:\n\n LL = Landsat sensor (LT for TM data)\n\n N = satellite number\n\n ppp = starting path of the product\n\n rrr = starting row of the product\n\n OO = WRS row offset (set to 00)\n\n YY = last two digits of the year of \n\n acquisition\n\n DDD = Julian date of acquisition\n\n MM = instrument mode (10 for MSS; 50 for TM)\n\n AA = file type:\n\n B1 = band 1\n\n B2 = band 2\n\n B3 = band 3\n\n B4 = band 4\n\n B5 = band5\n\n B6 = band 6\n\n B7 = band 7\n\n WO = processing history file \n\n TIF = GeoTIFF file extension\n\n\n\n\n\n\\* GAP MASKS\n\n\n\nAll Landsat 7 ETM+ SLC-off imagery processed on or after December 11, 2008, will include gap mask files. (Please note the difference between acquisition date and processing date, files dates are not necessarily the same.) The gap mask files are bit mask files showing the locations of the image gaps (areas that fall between ETM+ scans). One tarred and gzip-compressed gap mask file is provided for each band in GeoTIFF format. The file naming convention for gap mask files is identical to that described above for LPGS-processed GeoTIFF data, with "_GM" inserted before file type.\n\n\n\nIf gap mask files are not included with the data, a tutorial for creating them can be found at: http://landsat.usgs.gov/gap_mask_files_are_not_provided_can_I_create_my_own.php\n\n\n\n\n\n\\* README\n\n\n\nThe README_GTF.TXT (or README.GTF) is an ASCII text file and is this file.\n\n\n\n\n\n\\* READING DATA \n\n\n\nDelivered via file transfer protocol (FTP): data files are tarred and g-zip compressed and will need to be unzipped and untarred before the data files can be used. UNIX systems should have the "gunzip" and "tar"\n\ncommands available for uncompressing and accessing the data. For PC users, free software can be downloaded from an online source. Otherwise, check your PC, as you may already have appropriate software available.\n\n\n\nNo software is included on this product for viewing Landsat data. \n\n\n\n\n\nGENERAL INFORMATION and DOCUMENTATION\n\n\n\nLandsat Project Information:\n\nhttp://landsat.usgs.gov\n\n\n\nLandsat data access:\n\n \\* USGS Global Visualization Viewer (GloVis): http://glovis.usgs.gov\n\n \\* USGS EarthExplorer: http://earthexplorer.usgs.gov\n\n \\* USGS LandsatLook Viewer: http://landsatlook.usgs.gov\n\n \\* Landsat International Ground Station (IGS) network: \n\n http://landsat.usgs.gov/about_ground_stations.php\n\n\n\nFGDC metadata:\n\nhttp://www.fgdc.gov/metadata \n\n\n\nData restrictions and citation:\n\nhttps://lta.cr.usgs.gov/citation\n\n\n\n\\* National Snow and Ice Data Center (NSIDC) \n\nRadarsat Antarctic Mapping Project (RAMP) elevation data citation:\n\n\n\nLiu, H., K.

## 摘要 本数据集及其元数据声明由第三方提供给生物区域评估计划（Bioregional Assessment Programme），此处按原始提供的形式呈现。 Landsat TM与ETM+数据以GeoTIFF（GeoTIFF）格式提供，对应地形校正级（Level 1T）产品；若无法进行Level 1T处理，则可对应系统地形校正级（Level 1Gt）或系统校正级（Level 1G）产品。GeoTIFF定义了一组公开可用的TIFF标签，用于描述与TIFF图像相关的制图与大地测量信息。GeoTIFF格式可将栅格图像关联至已知大地测量模型或地图投影。 初始标签后紧随图像数据，而图像数据又可能被更多描述性标签打断。通过GeoTIFF格式，元数据与图像数据可被编码至同一文件中。Landsat 7 ETM+的GeoTIFF文件格式详见《Landsat 7 ETM+ Level 1产品数据格式控制手册（DFCB），LSDS-272》：http://landsat.usgs.gov/documents/LSDS-272.pdf。Landsat 4-5 TM的GeoTIFF文件格式详见《Landsat专题制图仪（TM）Level 1（L1）数据格式控制手册（DFCB），LS-DFCB-20》：http://landsat.usgs.gov/documents/LS-DFCB-20.pdf。 如需了解GeoTIFF的更多信息，请访问：http://trac.osgeo.org/geotiff ## 数据集历史 ### 组织与交付规范 GeoTIFF格式的Landsat数据各波段均以灰度、未压缩的8位无符号整数字符串形式交付。通过Level-1产品生成系统（LPGS）处理的数据会附带元数据（MTL）文件，同时还会包含图像处理过程中使用的地面控制点（GCP）文件。通过国家Landsat档案生产系统（NLAPS）处理的数据会附带处理历史（WO）文件。2008年12月11日后处理的Landsat 7 ETM+ SLC-off产品将新增一个名为gap_mask的目录，其中包含一组平面二进制扫描间隙掩码文件（每个波段对应一个文件）。请注意：处理日期与获取日期未必一致。 ### 数据文件名命名规则 #### LPGS处理的Landsat GeoTIFF数据 命名规范如下： `LMSppprrrYYYYDOYGSIVV_BN.TIF` 各字段含义如下： - `L`：代表Landsat - `M`：任务类型（E代表ETM+数据；T代表TM数据；M代表MSS数据） - `S`：卫星编号（7代表Landsat 7，5代表Landsat 5，4代表Landsat 4） - `ppp`：产品起始路径号 - `rrr`：产品起始与结束行号 - `YYYY`：获取年份 - `DOY`：儒略日 - `GSI`：地面站标识符 - `VV`：2位版本号 - `BN`：文件类型： - `B1`：波段1 - `B2`：波段2 - `B3`：波段3 - `B4`：波段4 - `B5`：波段5 - `B6_VCID_1`：波段6L（低增益，适用于ETM+） - `B6_VCID_2`：波段6H（高增益，适用于ETM+） - `B6`：波段6（适用于TM与MSS） - `B7`：波段7 - `B8`：波段8（适用于ETM+） - `MTL`：Level-1元数据 - `GCP`：地面控制点 - `TIF`：GeoTIFF文件扩展名 #### NLAPS处理的Landsat GeoTIFF数据 命名规范如下： `LLNppprrrOOYYDDDMM_AA.TIF` 各字段含义如下： - `LL`：Landsat传感器（LT代表TM数据） - `N`：卫星编号 - `ppp`：产品起始路径号 - `rrr`：产品起始行号 - `OO`：WRS行偏移量（固定为00） - `YY`：获取年份的后两位数字 - `DDD`：获取儒略日 - `MM`：仪器模式（MSS为10；TM为50） - `AA`：文件类型： - `B1`：波段1 - `B2`：波段2 - `B3`：波段3 - `B4`：波段4 - `B5`：波段5 - `B6`：波段6 - `B7`：波段7 - `WO`：处理历史文件 - `TIF`：GeoTIFF文件扩展名 ### 间隙掩码文件 2008年12月11日及之后处理的所有Landsat 7 ETM+ SLC-off影像均附带间隙掩码文件。请注意：获取日期与处理日期未必一致，文件日期与二者均无必然关联。间隙掩码文件为位掩码文件，用于标识图像间隙（ETM+扫描线之间的区域）的位置。每个波段对应一个以GeoTIFF格式存储的tar打包且gzip压缩的间隙掩码文件。间隙掩码文件的命名规范与LPGS处理的GeoTIFF数据一致，仅在文件类型前添加`_GM`后缀。 若数据未附带间隙掩码文件，可通过以下教程自行创建：http://landsat.usgs.gov/gap_mask_files_are_not_provided_can_I_create_my_own.php ### 说明文件 `README_GTF.TXT`（或`README.GTF`）为ASCII文本文件，即本文档。 ### 数据读取方式 本数据集通过文件传输协议（FTP）交付，数据文件均经过tar打包与gzip压缩，使用前需先解压缩并解包。UNIX系统可使用`gunzip`与`tar`命令完成解压与提取操作。PC用户可从在线资源下载免费软件，或检查本地是否已安装合适的解压工具。 本产品未附带用于查看Landsat数据的软件。 ## 通用信息与文档 Landsat项目官方信息：http://landsat.usgs.gov Landsat数据获取渠道： - USGS全球可视化查看器（GloVis）：http://glovis.usgs.gov - USGS地球资源探索器（EarthExplorer）：http://earthexplorer.usgs.gov - USGS LandsatLook查看器：http://landsatlook.usgs.gov - Landsat国际地面站（IGS）网络：http://landsat.usgs.gov/about_ground_stations.php 联邦地理数据委员会（FGDC）元数据标准：http://www.fgdc.gov/metadata 数据使用限制与引用要求：https://lta.cr.usgs.gov/citation #### 国家冰雪数据中心（NSIDC）相关数据引用 Radarsat南极绘图计划（RAMP）高程数据引用格式： Liu, H., K.
