GLOST - Global Spatial Tiles
收藏资源简介:
GLOST - Global Spatial Tiles This dataset contains a collection of vector square tiles in CSV format for the entire extent of the world (except polar regions) . Usage These tiles can be used as: Catalog and indexing large spatial datasets. Automatic retrieval layer for large spaial dataset. Typical zonal statistics for GIS analysis. Scales Available The dataset is available at the following spatial resolutions: 0.25 degree: glost_00P25_0_0.csv 0.5 degree: glost_00P50_0_0.csv 1.0 degree: glost_01P00_0_0.csv 2.0 degree: glost_02P00_0_0.csv 4.0 degree: glost_04P00_0_0.csv Formatting Format: CSV (.csv) with semicolon ';' as separator and standalone read-me header. Coordinate Reference System (CRS): WGS 84 EPSG:4326 Data Type: miscellaneous Text encoding conventions 'P' as decimal separator 'N' / 'S' for latitude signal 'E' / 'W' for longitude signal '-' hyphen as separator Main columns Column Description cd_board Tile board code (like a chessboard) in {size}-{row}-{column} cd_llcorner Lower-left corner code of the tile in {size}-{x_min}-{x_max} cd_bbox Bounding box code in {x_min}-{x_max}-{y_min}-{y_max} geometry_bbox WKT geometry of the full grid of tiles geometry_centroid WKT geometry of the tile centroid geometry_llcorner WKT geometry of the lower-left corner License CC-BY 4.0 Citation If you use this dataset, please cite as: Possantti, I.
