怎么转换SRTM hgt数据到OSM
-jacky
参考环境
Ubuntu16.04 python3.5
第一步 搭建使用环境
搭建python3.5开发环境
验证
首先验证当前python版本，验证方法如下：
打开终端(control + alt + T),输入
这是python2.7的版本，phyghtmap不依赖2.7的版本，只需要3.x的版本
jacklin@ubuntu:~$ python --version
Python 2.7.12
这是python3.5.2的版本, phyghtmap依赖3.x的版本，所以此版本必须安装，建议>=3.0即可
jacklin@ubuntu:~$ python3 --version
Python 3.5.2
如果验证python版本号是3.x，则参考如下Case 0
如果验证python3 没有版本号，则参考如下Case1
case 0
可能当前只安装了python3.x，而且没有修改环境变量，所以只需要给python3换个别名即可
vim ~/.bash_rc
alias python3=你的python3完整路径
case1
可能没有安装python3，所以安装即可
sudo apt-get install python3
安装完后继续回去验证
安装好了继续第二步
第二步 下载phyghtmap
- Source distibution: phyghtmap_2.20.orig.tar.gz
下载phyghtmap_2.20.orig.tar.gz,默认放在~/Downlaod目录下
jacklin@ubuntu:~/Downloads$ ls *.tar.gz
phyghtmap_2.20.orig.tar.gz
jacklin@ubuntu:~/Downloads$ tar zxvf phyghtmap_2.20.orig.tar.gz

phyghtmap-2.20/LICENSE_GPL-2
解压完毕，进入解压的目录
jacklin@ubuntu:~/Downloads$ cd phyghtmap-2.20/
查看解压的文件
jacklin@ubuntu:~/Downloads/phyghtmap-2.20$ ls
build dist LICENSE_GPL-2 phyghtmap.egg-info setup.py
Changelog docs MANIFEST.in PKG-INFO
COPYRIGHT INSTALL phyghtmap README
第三步 安装phtghtmap
查看安装说明
jacklin@ubuntu:~/Downloads/phyghtmap-2.20$ cat INSTALL
The installation requires a working python setuptools installation.
To install it on a debian-like system say apt-get install python3-setuptools.
The program itself should run with python >= 3.0.
Some additional requirements have to be installed on your system in order to run
phyghtmap:
* python3-pkg-resources (on Debian-like systems, say apt-get install
python3-pkg-resources)
* python3-matplotlib (on Debian-like systems, say apt-get install
python3-matplotlib)
* python3-bs4 (on Debian-like systems, say apt-get install
python-bs4)
* python3-numpy (on Debian-like systems, say apt-get install python-numpy)
To install phyghtmap, finally say
sudo python setup.py install
which will install the stuff on your system.
安装上述依赖库
jacklin@ubuntu:~/Downloads/phyghtmap-2.20$ sudo apt-get install python3-setuptools
jacklin@ubuntu:~/Downloads/phyghtmap-2.20$ sudo apt-get install python3-pkg-resources
jacklin@ubuntu:~/Downloads/phyghtmap-2.20$ sudo apt-get install python3-matplotlib
jacklin@ubuntu:~/Downloads/phyghtmap-2.20$ sudo apt-get install python3-bs4
jacklin@ubuntu:~/Downloads/phyghtmap-2.20$ sudo apt-get install python3-numpy
安装完依赖库，安装phyghtmap
jacklin@ubuntu:~/Downloads/phyghtmap-2.20$ sudo python setup.py install
验证phyghtmap版本
jacklin@ubuntu:~/Downloads$ phyghtmap -v
phyghtmap 2.20
出现版本号即可使用
第四步 转换SRTM hgt数据
自行下载hgt文件到一个指定文件夹，此处假设hgt文件夹路径在~/Download
jacklin@ubuntu:~/Documents/srtm$ cd ~/Downloads/
jacklin@ubuntu:~/Downloads$ ls
hgt2Osm
jacklin@ubuntu:~/Downloads$ cd hgt2Osm/
jacklin@ubuntu:~/Downloads/hgt2Osm$ ls
N22E114.hgt N22E115.hgt N22E116.hgt
可见文件夹内有3个hgt文件
现在转换这3个hgt文件为osm文件，保存在当前目录
如下命令中，5是等高线最小单位，数字越小，产生的osm文件越大，可自行调整20 100 400 等数据
jacklin@ubuntu:~/Downloads/hgt2Osm$ phyghtmap -s 5 --start-node-id=$((1<<33)) --start-way-id=$((1<<33)) --max-nodes-per-tile=0 ./*.hgt
hgt file ./N22E114.hgt: 1201 x 1201 points, bbox: (114.00000, 22.00000, 115.00000, 23.00000)
hgt file ./N22E115.hgt: 1201 x 1201 points, bbox: (115.00000, 22.00000, 116.00000, 23.00000)
hgt file ./N22E116.hgt: 1201 x 1201 points, bbox: (116.00000, 22.00000, 117.00000, 23.00000)
jacklin@ubuntu:~/Downloads/hgt2Osm$ ls -l
total 357612

验证
上述文件lon114.00_117.00lat22.00_23.00_local-source.osm即转换完成的osm文件，需要使用FYIII的地图导入工具-Import，和详图一起导入，才能在FYIII中加载，导入教程的中文版下次再出
