Development of a Geo-electrical Database Management System (GDBMS) for Geoscientist Application.

Thesis Abstract

In the field of geosciences, large sum of data are always  acquired, processed and interpreted for different geographic locations, but only few of the data are well managed, such that, they can be useful for subsequent geoscience related surveys carried out in the same geographical locations. This is a challenge in the geoscience field, and it would be beneficial to the field when this challenge is resolved and it becomes a utilisable concept. It is in this regard that a database  management  system  (GDBMS)  for  geo-electric  data  storage,  retrieval,  and manipulations  (corrected  and  updated)  for  geoscientist  application  is  conceived.   With  the application  of  vertical  electrical  sounding  technique  of  electrical  prospecting  method,  17 location  points  were  occupied  at  Owena,  Ondo  east  local  government.  Deriving  from  the interpreted geophysical data acquired are the field curve types, geoelectric section and relevant  hydrogelogic maps such as anisotropy, longitudinal conductance and corrosivity maps of the area.  Through  programing  coding  involving  C-sharp  and  SQL  (Structured  query  language) programming language, a DBMS software application is developed. Using the results of the geophysical investigation, the geoelectric DBMS (GDBMS) was developed. The  deployment of this developed GDBMS enhance the displaying, editing etc of geoscientific information that can be applied in the field of engineering geophysics, environmental and hydrogeophysics.
