Create a GDAL CLI context from linked binaries

Resolves executable paths for GDAL utilities (e.g., gdalinfo, gdalwarp, ogr2ogr) under a specific binDir and prepares a per-call environment (PATH + optional vars).

Usage

gdal_context(
  binDir,
  env = character(),
  log_file = file.path(tempdir(), "gdal-run.ndjson"),
  help_cache_dir = file.path(tempdir(), "gdal-help-cache")
)

Arguments

binDir

Character. Directory containing GDAL executables.

env

Named character vector. Additional env vars (e.g., GDAL_DATA, PROJ_LIB).

log_file

Character. NDJSON log file path (default: "gdal-run.ndjson" in tempdir()).

help_cache_dir

Character. Directory for cached help texts (default: "gdal-help-cache" in tempdir()).

Value

A list (class "gdal_context") with resolved executables and env.
