It uses the [ASPRS](https://www.asprs.org/) (American Society for Photogrammetry and Remote Sensing) [Lidar point classification](https://desktop.arcgis.com/en/arcmap/latest/manage-data/las-dataset/lidar-point-classification.htm). See [LAS specification](https://www.ogc.org/standards/LAS) for details.\n\nThis COG type is based on the Classification [PDAL dimension](https://pdal.io/dimensions.html) and uses [`pdal.filters.range`](https://pdal.io/stages/filters.range.html) to select a subset of interesting classifications. Do note that not all LiDAR collections contain a full compliment of classification labels.\nTo remove outliers, the PDAL pipeline uses a noise filter and then outputs the Classification dimension.\n\nThe STAC collection implements the [`item_assets`](https://github.com/stac-extensions/item-assets) and [`classification`](https://github.com/stac-extensions/classification) extensions. These classes are displayed in the \"Item assets\" below. You can programmatically access the full list of class values and descriptions using the `classification:classes` field form the `data` asset on the STAC collection.\n\nClassification rasters were produced as a subset of LiDAR classification categories:\n\n```\n0, Never Classified\n1, Unclassified\n2, Ground\n3, Low Vegetation\n4, Medium Vegetation\n5, High Vegetation\n6, Building\n9, Water\n10, Rail\n11, Road\n17, Bridge Deck\n```\n","item_assets":{"data":{"type":"image/tiff; application=geotiff; profile=cloud-optimized","roles":["data"],"title":"COG data","raster:bands":[{"name":"Classification","unit":"metre","sampling":"point","data_type":"int16","description":"Raster for Classification PDAL dimension, ASPRS Lidar Point Classification Standard"}],"classification:classes":[{"value":0,"description":"Never Classified"},{"value":1,"description":"Unclassified"},{"value":2,"description":"Ground"},{"value":3,"description":"Low Vegetation"},{"value":4,"description":"Medium Vegetation"},{"value":5,"description":"High Vegetation"},{"value":6,"description":"Building"},{"value":9,"description":"Water"},{"value":10,"description":"Rail"},{"value":11,"description":"Road"},{"value":17,"description":"Bridge Deck"}]},"thumbnail":{"type":"image/png","roles":["thumbnail"],"title":"3DEP Lidar COG"}},"stac_version":"1.0.0","msft:group_id":"3dep-lidar","msft:container":"usgs-3dep-cogs","stac_extensions":["https://stac-extensions.github.io/item-assets/v1.0.0/schema.json","https://stac-extensions.github.io/raster/v1.1.0/schema.json","https://stac-extensions.github.io/classification/v1.0.0/schema.json"],"msft:storage_account":"usgslidareuwest","msft:short_description":"3DEP Lidar collection for Cloud Optimized Geotiffs (COGs) created according to PDAL's Intensity dimension","msft:region":"westeurope"}
