Sea Level Analysis using ENVISAT

 Content: In this project the goal is to retrieve reliable information about the sea level change from 2004 to 2008 using ENVISAT data. Furthermore the main concepts for a software development and implementation shall be simulated. For this purpose a program has to be developed that is capable of converting the ENVISAT raw data into a matlab readable format, applying all necessary corrections given by the data itself and interpolate the data to retrieve an assumption for the past sea level change from 2004 to 2008.   Acceptance Review Presentation Final Acceptance Review Requirements defined in the beginning of the project Defined work packages for software development Data Reduction and Flag Analysis Applied corrections during the processing Interpolation Algorithm and techniques Animation of absolute Sea Surface Height for all cycles Sea Surface Height per Year with a mean rise of 8.7mm/year Interpretation of most visible changes correlated with ocean surface currents Quantative validation of results including comparison with other studies Local Analysis and interpretation of results using specific POI Testing Procedures for the developed software Requirement Review for specific parts of the software development Trac, SVN and Wiki Pages As a version control system was part of the requirements of the project, a website was created for the trac system and SVN version control system used during the development of the program.
