GRTSmh_brick: the raster data source GRTSmaster_habitats converted to 10 hierarchical cell address levels at the original resolution

The data source file is a 10-layered GeoTIFF file, derived from the raster data source GRTSmaster_habitats (link). Both GeoTIFFs (GRTSmaster_habitats, GRTSmh_brick) use the INT4S datatype. The GRTSmh_brick data source (resolution 32 m) holds the decimal integer ranking numbers of 10 hierarchical levels of the GRTS cell addresses, including the one from GRTSmaster_habitats (with GRTS cell addresses at the resolution level).

See R-code in the GitHub repository 'n2khab-preprocessing' at commit ecadaf5 for its creation from the GRTSmaster_habitats data source.

A reading function to return the data source in a standardized way into the R environment is provided by the R-package n2khab.

The higher-level ranking numbers of the RasterBrick allow spatially balanced samples at lower spatial resolution than that of 32 m, and can also be used for aggregation purposes. The provided hierarchical levels correspond to the resolutions vector 32 * 2^(0:9) (minimum: 32 meters, maximum: 16384 meters).

Beware that not all GRTS ranking numbers are present in the data source, as the original GRTS raster has been clipped with the Flemish outer borders (i.e., not excluding the Brussels Capital Region).

本数据集源文件为10层GeoTIFF（地理标记图像文件格式）文件，源自栅格数据源GRTSmaster_habitats（链接见原文）。两款GeoTIFF文件（GRTSmaster_habitats与GRTSmh_brick）均采用INT4S数据类型。其中GRTSmh_brick数据源（分辨率32米）存储了GRTS格网地址的10个层级的十进制整数排名编号，包含来自GRTSmaster_habitats的、对应原始分辨率层级的GRTS格网地址。

可于GitHub仓库'n2khab-preprocessing'的ecadaf5提交版本中，获取由GRTSmaster_habitats数据源生成本数据集的R代码。

R包n2khab提供了可将本数据源以标准化格式导入R运行环境的读取函数。

此RasterBrick（栅格砖）的高层级排名编号，支持在低于32米的空间分辨率下开展空间均衡采样，同时也可用于数据聚合操作。本数据集提供的层级与分辨率序列32×2^(0:9)一一对应（最低分辨率为32米，最高分辨率为16384米）。

请注意：本数据源并非包含所有GRTS排名编号，因原始GRTS栅格已按照佛兰芒地区外边界进行裁切（即未排除布鲁塞尔首都大区）。
