STACTA-时空资产目录平铺资产
3.3 新版功能.
司机简称
STACTA
Driver built-in by default
This driver is built-in by default
This driver supports opening JSON files following the Spatio-Temporal Asset Catalog Tiled Assets specification. Such JSON file references tiles (also called metatiles), split from a potentially big dataset according to a tiling scheme, with several zoom levels. The driver provides a single raster view, with overviews, of the dataset described by the JSON file. The driver supports metatiles of arbitrary size.
开放语法
STACTA数据集/子数据集可以使用以下语法之一进行访问:
filename.json
:本地文件STACTA:"https://example.com/filename.json"
:远程文件STACTA:"filename.json":my_asset
:指定本地/远程文件的资产STACTA:"filename.json":my_asset:my_tms
:指定本地/远程文件的资源和平铺方案
The root of the JSON file must be of type Feature
.
打开选项
支持以下打开选项:
WHOLE_METATILE
=YES/NO。如果设置为YES,metatiles将完全下载(到内存中)。否则,默认情况下,如果metatiles大于阈值,则将以分段方式访问它们。SKIP_MISSING_METATILE
=YES/NO。如果设置为YES,则将跳过缺少的metatile而不会出错,并且数据集中的相应区域将填充nodata值,如果没有nodata值,则填充为零。也可以使用GDAL_STACTA_SKIP_MISSING_METATILE
配置选项。
子数据集
如果STACTA JSON文件包含多个资产模板和/或平铺方案,驱动程序将返回子数据集名称列表,以打开每个可能的子数据集。
驱动程序功能
Supports VirtualIO
This driver supports virtual I/O operations (/vsimem/, etc.)
