Read Ocean Current Data from NetCDF File in Matlab

Thursday, 13 February 2014 | by Riza | | 4 comments

Before create a script, make sure your Matlab has integrated with NetCDF toolbox, if don't have, you can search in google or any search engine to get toolbox, but in this post I use nctoolbox, for further information such as installation, guide and download nctoolbox open this site. Sea current data used here is NetCDF file, for example I use current data from Ocean Surface Current Analyses - Real time (OSCAR) NOAA which can be downloaded here. Download...

ArcGIS for Ocean : How to Make Base Map in ArcMap (Part 2)

Monday, 10 February 2014 | by Riza | , | No comments

Before continue,  please read this post : ArcGIS for Ocean : How to Make Base Map in ArcMap (Part 1) Ok lets continue to the next step. After put the data in ArcCatalog 10.1, open ArcMap 10.1. In the left side, you will see Table of Contents box, right click Layers and choose Add Data. Add the data downloaded in folder made previously. Add coastlines in GSHHS_shp folder and choose full resolution in h folder and then add GSHHS_h_L1...

ArcGIS for Ocean : How to Make Base Map in ArcMap (Part 1)

Sunday, 9 February 2014 | by Riza | , | No comments

In this post, I will describe how to make base map in ArcMap for oceanography purpose. This base map is a map consist of coastlines; administrative boundaries, rivers and road of the country; maritime boundaries; and total sediments thickness of the world ocean; You can add any data such as bathymetry, SST etc, but in this post I only use data mentioned previously. You need to install and running ArcMap and ArcCatalog, in this excercise I use ArcMap...

Create Bathymetry Map in Matlab from xyz Data

Thursday, 6 February 2014 | by Riza | , | 41 comments

Matlab is a high-level computing language. There are many purpose using this program. In this post, I will describe how to make bathymetry map from xyz data in Matlab. Main idea of the process is only make x data, y data and z data to be a grid because of use surf command, so simple. OK lets start ..... Before make a Matlab script, you must have xyz data, as an example I use data from  ETOPO 1 National Geophysical Data Center (NGDC) NOAA,...

A. GENERAL EXPLANATION : METODE HUCKEL Metoda Huckel atau metoda orbital molekul Huckel (HMO), diusulkan oleh Erich Huckel pada tahun 1930, adalah cara yang sangat sederhana pada kombinasi linear dari orbital atom - orbital molekul (linear combination of atomic orbitals molecular orbitals/ LCAO MO) untuk menentukan energi orbital molekul elektron pi dalam sistem hidrokarbon terkonjugasi, seperti etena, benzena dan butadiena. Metode extended...
