Ubuntu at Win 10 and install GMT

早聞win10可運行Ubuntu, 但遲遲未試,
結果這次安裝發現, 果真容易啊!
從沒裝過Ubuntu, this is the first time!
之前都試Red Hat Group, 想說邏輯上應相似, 見招拆招吧!

### Install Ubuntu at Windows 10
跟安裝Windows程式一樣輕鬆,
選一選安裝, 重開機就搞定!(網路上有圖文並茂的Step by Step說明)
前後約10 min.

### Install fortran
sudo apt install gfortan
真的就這樣就過了!簡單程式測試也ok!

### Install GMT
sudo apt-get install gmt gmt-dcw gmt-gshhg
若要高解析海岸線,參考之前寫的!http://shicinw.blogspot.com/2018/06/gmt5.html

### Install Imagemagick
sudo apt-get install imagemagick
這太多人用, 裝起來毫無問題

結論:
因為windows版本跟apt支援, 所以裝起來很無腦(應說輕鬆愜意啦)!
用cygwin在windows的方法可以考慮轉換一下!

CDO (Climate Data Operators) 套件無腦安裝法@ CentOS 7

工作上接觸Outgoing Longwave Radiation (OLR)資料,
需要安裝CDO (Climate Data Operators) 套件作資料的轉檔,
剛好OS是CentOS7 (CentOS Linux release 7.5.1804 )故以下這篇超有幫助,
自己blog備份,以免屆時連接失效,
另外撰文此時最新版cdo-1.9.4.tar.gz, 但是make 有error message沒過
降版本cdo-1.9.0.tar.gz 就ok!

    Installsing CDO in CentOS 7

CDO - Climate Data Operator is a tool developed for perform various operation on Climate and NWP model output data. It can handle netCDF, HDF5, GRIB 1/2 with compression. It is a very efficient tool work with large dataset found in a climate model for its simplicity and speed. I wish to write some tutorials on working with CDO, however this one only covers the installation of CDO in CentOS 7 system.

To install the basic packages, I will use Yum package manager. First install the netCDF, HDF5 packages as follows -

# yum install nco netcdf netcdf-devel hdf hdf-devel hdf5 hdf5-devel

You can see I have also installed nco, for my convenience actually. If you are not already familiar to nco, please see here.

 Now downloading and installing the cdo. Use following commands, hope they will make sense :)

~ wget -c wget -c https://code.zmaw.de/attachments/download/13525/cdo-current.tar.gz
~ tar -xvzf cdo-current.tar.gz
~ cd  
~ ./configure --with-netcdf=/usr --with-hdf5=/usr
~ make
~ sudo make install

Here, is the folder you get after extraction. It depends on the current version. This should install cdo in your system, and you can access the command by simply typing cdo in the terminal. Let me know if you have any problem. 

Happy CDOing :-)

GMT 在CentOS 6下 EPEL套件是gmt4

先講結論
1. CentOS 6 下EPEL 套件是gmt4
   也可以用yum 輕鬆安裝,不用重新編譯的老方法
    CentOS 6 安裝GMT5 要自己編譯
3. CentOS 7反之, EPEL 套件是GMT5
    要用gmt4 要自己編譯

################################################

因為CentOS 7 在yum 下很容易安裝GMT5
手賤嘗試CentOS 6 的機器下安裝, 但是裝起來是gmt4版
過程中搞到原來gmt4版也不能run, 影響原本routine jobs! 很煩惱
又要重新編譯了~~~
後來看到此文, 立馬又恢復

Dear all,
I just found the solution 
it's because of rpm:
first off all I did this:
cd /etc/yum.repos.d/
I just keep these :
CentOS-Base.repo CentOS-Media.repo
CentOS-Debuginfo.repo CentOS-Vault.repo
CentOS-fasttrack.repo

and then deleted others.(it's importatnt do keep JUST CENTOS REPO at this step)

second: I updated Cent by yum update
third: I restarted Cent
forth: yum remove GMT
yum remove epel-release (if it exit)
fifth : it's important to delet all of hdf5* library that I installed befor
so I did this : yum remove hdf5*


after all I installed epel again : yum install epel-release
then I installed GMT : yum install GMT

it's amazing friend!!

GMT5 成功安裝過程與測試畫海灘球

新server, GMT5出了一陣子, 過去GMT5 安裝都沒成, 試試看
OS: CentOS Linux release 7.5.1804

照GMT官網所述 GMT5 安裝在CentOS下很容易

yum裡面都有,不過default的yum 套件庫應該是沒有GMT

所以要先擴充套件庫epel

sudo yum install epel-release

然後就直接用yum (超容易啊!回想之前真是痛苦)

sudo yum install GMT gshhg-gmt-nc4-all dcw-gmt

環境也不用設,都放在系統灌好的位置下,立馬可以用!                                                                         

這樣安裝假如還要用高解析海岸線(e.g. pscoast -Df or -Dh)需要在官網直接下載

撰文此時位置與版本http://gmt.soest.hawaii.edu/files/download?name=gshhg-gmt-2.3.7.tar.gz

然後解tar解壓縮到想放的位置,並在script(應該可以設在環境中,但沒試)中指向該位置

設定方法如同gmtset,但要合於GMT5的語法

例如 gmt gmtset DIR_GSHHG = /usr/share/gmt/gshhg-gmt-2.3.7

這樣就可以在pscoast中用了!

##############################

測試畫海灘球

用之前gmt4版的script改成GMT5的

以下為小感想或試出的差異

1. 所有GMT5版本都濃縮在gmt這個指令裡, 所以所有指令開頭都是gmt(包含gmtset)

2. grdimge, pscoast, psscale, psxy , 在開頭加gmt後接gmt4版語法都可以用(也有可能是我沒用太多功能選項)

3. gmtset 才設定兩個, 兩個都不一樣, 可以參考error message或跑script會產生出的gmt.conf檔

   原本 gmtset PLOT_DEGREE_FORMAT +ddd:mm:ssF 改為 gmt gmtset FORMAT_GEO_MAP = +ddd:mm:ssF

   原本 gmtset ANNOT_FONT_SIZE_PRIMARY 20p 改為 gmt gmtset FONT_ANNOT_PRIMARY = 20p,Helvetica,black

4. pstext是常用而改比較大的

   gmt4一定要輸入指定七項(x, y, size, angle, fontno, justify, text),

   但GMT5只要輸入x,y,text三項,其餘放在指令的參數裡, 沒寫就用預設值

   可以參考官網英文版或http://gmt-tutorials.org/scatter_plot.html 中文版

   例如 -F+f[字體大小,字體名稱,顏色]+j[對齊選項]+a[角度] 

   原本 echo "122.30 25.15 15 0 0 LM Taiwan" | pstext -R -JM -P -O -N >>ofn

   改為 echo "122.30 25.15 Taiwan" | gmt pstext -R -JM -F+f15p+jLM -P -O -N >>ofn

   

5. psmeca 原本 -Sa下用 -C1/0, 在GMT5 只能用-C1 才能過
