安装GRASS GIS并在Linux机器中通过python使用它？

Question

是否有 bash 脚本来安装 GRASS GIS 并在 Linux 机器中将其与 python 一起使用？

Answer 1

sudo apt update
sudo apt -y install grass-dev
export GRASSBIN=$(which grass)
pip install grass-session
curl https://sh.rustup.rs -sSf | sh -s -- -y
source "$HOME/.cargo/env"
pip install pygrass
# >>> from grass_session import Session
# >>> import grass

Answer 2

从 GRASS GIS 版本 8.4+ 开始，不再需要 pip 包，但现在提供内部 Python API。

示例：导入 GRASS GIS Python 绑定（需要 8.4+）并测试 r.in.pdal

export PYTHONPATH=$(grass --config python-path)
python

import grass.script as gs
import urllib.request

# download a small sample data file (LiDAR points)
urllib.request.urlretrieve(
    "https://github.com/OSGeo/grass/raw/main/docker/testdata/simple.laz",
    "/tmp/simple.laz",
)

# full path to new project
project = "/tmp/grassproject_epsg_25832"
gs.create_project(project, epsg="25832")

with gs.setup.init(project):
    print("GRASS GIS session: tests for PROJ, GDAL, PDAL, GRASS GIS")
    print(gs.parse_command("g.gisenv", flags="s"))

# simple test: scan the LAZ file for boundary extent
gs.run_command(
    "r.in.pdal",
    input="/tmp/simple.laz",
    output="count_1",
    method="n",
    flags="g",
    resolution=1,
    overwrite=True,
)
