Eastern Sea of Vietnam is the world's largest semi-open sea and is bounded by archipelagos, islands, mainland and connected partially with Pacific and Indian Ocean. Its total water surface area is about 2,974,600km2. Vietnamese and foreign geoscientists have researched, got samples and mapped the geological map of Eastern Sea since 1960s but no guidance or right method was carried out to map, especially in presenting geological units on geological map.

The Potential of Soil Survey Data in a Quantitative Evaluation of Surficial Geology Mapping in Northern Maine by Rosalia Evans

Using the analytic hierarchy process (AHP) method for multi-index evaluation has special
advantages, while the use of geographic information systems (GIS) is suitable for spatial
analysis. Combining AHP with GIS provides an effective approach for studies of mineral
potential mapping evaluation. Selection of potential areas for exploration is a complex
process in which many diverse criteria are to be considered.
Comprehensive and authoritative baseline geospatial data content is crucial
to the nation and to the U.S. Geological Survey (USGS). To maintain its prominence,
realize its potential, and fulfill its mission to develop and distribute these
national data assets in a fast-moving information technology environment,
USGS needs a coordinated geographic information science (GIScience) research
presence that provides the scientific underpinning for these operations and exerts
leadership in research that is critical to serving USGS’s unique role.
Engineering is a subject that ranges from large collaborations to small individual projects. Almost all engineering projects are beholden to some sort of financing agency: a company, a set of investors, or a government. The few types of engineering that are minimally constrained by such issues are pro bono engineering and open design engineering.
Humankind’s fascination with Mars predates
recorded history. The bright planet with the reddish tint
is unique among the other celestial objects. Tycho
Brahe’s observations of its unpredictable motion were
deciphered by Johannes Kepler in the early 17th century
as he developed his laws of planetary motion.
Galileo trained his telescope on Mars and saw it as a
disk in 1610. Later in the 1600s, Christiaan Huygens
and Gian Cassini drew the first maps of the Martian

ABSTRACT. The Mekong Delta in the south of Vietnam is a highly dynamic landscape with rapid changes in land use. Costal forests of mangrove (Rhizophoraceae, Sonneratiaceae and Avicenniaceae) and the more inland Melaleuca forests are changed into shrimp ponds and rice fields.
