- Researcher, Colorado State University, U.S.A.,
1993 - 1998.Studied the theory and operated different types of
Geographical Information System (GIS) programs, both raster and vector based
such as IDRISI, ARCINFO and MAPINFO.
- Studied the theory and operated various types
of Global Positioning System (GPS) programs and GPS receivers both in
autonomous and differential correction modes.
- Developed knowledge and explored the uses of
GIS and GPS in many applications, such as generation of georeferenced digital (electronic)
maps, environment protection, surveying and remote sensing, with a great
emphasis on their applications in precision farming.
- An extensive field study was conducted to
implement the precision farming technique, where soil samples from an
agricultural field were collected and analyzed to determine the appropriate
herbicide application rate for different field locations.
- Utilized a GIS program and GPS technology to
develop a digitized GIS map of the studied field; the map was used as a
herbicide application rate management map.
Used a real-time differentially corrected GPS
system to locate a ground sprayer in the field and precisely determine its
position coordinates (latitude and longitude).
- Integrated the knowledge of GIS and GPS into
the development of a GPS and GIS-based spatially variable rate herbicide
application system. The developed system
was capable of automatically changing, on-the-go, the amount of chemicals to
fit the requirements of current sprayer field location in the study field in
order to reduce environment contamination and farming cost. The system was
tested in the field and proven to be effective and efficient.
- Research Assistant, Colorado State University, U.S.A.,
1989-1992.Studied and operated various data collecting systems.
- Studied and calibrated different types of
- Conducted a field study to reveal the
accuracy of a commercial control system in providing a constant application
rate of agricultural chemicals at different ground speeds of a field chemical
- Conducted extensive field experiments to
monitor the behavior of a ground field sprayer with and without a control
- Proficiency in GIS and GPS
systems. This includes developing
digitized GIS maps, location determination using satellite signals, remote
sensing, surveying, and managing spatially-variable data.
- Knowledge in agricultural
chemicals and their safety procedures.
- In-depth knowledge of
site-specific (precision) farming and different techniques ofapplying it, such
as the implementation of GIS and GPS technologies.
- Knowledge in field data
acquisition devices and data analysis.
- Experience in designing and
performing different tests and experiments both in the lab and out in the field
- Proficiency in all MICROSOFT
OFFICE programs and engineering-related software programs, such as SURFER and
- Skilled knowledge in computer
- Proficient in GIS programs and GPS
communication software programs.
