INTRODUCTION
1. The urgency of the thesis
Vietnam has rich and diverse mineral resources. However, the
management of mineral resources still has many shortcomings and
limitations; resulting in many illegal exploitation activities.
Therefore, the problem of rational management and use of mineral
resources for re-investment, towards sustainable development is
extremely important, urgent and a national strategy.
Today, with the development of science and technology and the
fourth industrial revolution taking place in all fields, including the
fields of state management of mineral resources, the application of
open source WebGIS platforms in building mineral resource
management database is reasonable, suitable as well as to ensure
topicality and reliability. Although, there have been a number of
studies on solutions based on open source WebGIS technology, but
these studies still have some problems such as building solution,
asynchronous techniques, and without integration of remote sensing
image data processing technology ...
By such facts, the thesis "Research on technical solutions to build
mineral resource management database using WebGIS technology"
is an urgent issue with practical scientific significance to solve the
above situation.
2. The research objectives of the thesis
To establish the scientific basis and methodology to build
WebGIS database in order to improve the efficiency of mineral
exploitation management and activities.
3. Target and area of this study
- Target of this study: The direct scientific object is to study
technical solutions to build WebGIS database for mineral resources
classes, suitable for the efficient management of mineral resources in
the practical conditions of Vietnam.
- Area of this study: Research scope of content is open source
WebGIS technology and some techniques for extracting mineral
information on remote sensing image implemented in Quy Hop
district - Nghe An province.
4. Method of research
- Analysis and synthesis method: Collection of GPS measurement
data, remote sensing image data, GIS vector data ...
2
- Remote sensing method: Processing of remote sensing image
data is to build potential mineral data layer ...
- GIS method: processing, editing, spatial analysis of GIS data
and remote sensing images.
- Comparison method: comparing and evaluating the research
results on the application of WebGIS technology in database
building and mineral resource management; compare results of
potential data layer on mineral resources based on information
extraction technique based on remote sensing image with
information related to mineral resource management, exploitation
and use.
- Modeling method: The research guide in the thesis is modeled to
make it easy to understand and use in the data processing process.
- Programming technique: selecting programming languages in
combination with libraries to support data processing, designing and
installing algorithms to build and test WebGIS systems to build
databases and manage documents. raw minerals.
5. The scientific and pratical meaning of this thesis
- Scientific meaning: To establish a scientific basis and technical
solutions to build WebGIS database for mineral resource
management.
- Practical meaning: The research results can be applied to build
WebGIS database for mineral management in general and WebGIS
database for Quy Hop district - Nghe An province in particular.
6. Defense thesis and new points of the thesis
Defense thesis 1: The solution of extracting information from
remote sensing images combined with GIS analysis based on an open
foundation is meeting the topicality and reliability in building
mineral resource database.
Defense thesis 2: Open source WebGIS technology is a suitable
technical solution satisfying to the management of large database of
mineral resources.
7. The new highlights of the thesis
- Propose technical solutions to build spatial database of mineral
resources from the extraction technique of remote sensing image and
GIS analysis based on open platform to serve the problem of
monitoring and assessing the current situation.
- Build mineral resource management system model based on
open source WebGIS platform suitable for managing large database

of mineral resource.
8. The layout of the thesis
The thesis is presented in 187 pages, including the preamble,
thesis content, conclusions and proposals, author's work list,
references, table of contents. The content of the thesis includes 4
chapters with 106 figures and diagrams, and 24 tables/sheets.
CHAPTER 1. OVERVIEW OF RESEARCH MATTERS ON
BUILDING WEBGIS DATABASES FOR MANAGEMENT OF
MINERAL RESOURCES
1.1. Current situation of mineral resources in Vietnam and Nghe
An province
1.1.1. Current situation of mineral resources in Vietnam
Mineral resources have strategic significance and serve as a
resource for the country's socio-economic development. However,
many illegal mineral exploration activities still take place. One of the
reasons leading to this situation is not good ability to monitor and
manage mineral resources. According to a study by the Institute of
Natural Resources Management published in 2013, Vietnam ranked
43/58 in the capacity of mineral governance.
1.1.2. Current situation of mineral resources in Nghe An province
Nghe An is a province with abundant mineral resources compared
to many other provinces. Nghe An province currently has 113
mineral mines with large reserves, 171 points of ore. However,
besides the positive development, the process of management and
exploitation of mineral resources in Nghe An province has revealed
many limitations such as:
- Some localities have lax in management of natural recources.
- Nghe An mineral resource database includes many categories
such as paper maps, documents, decisions, mineral exploration,
investigation, mining and processing licenses as well as data on
survey results, exploration but stored in many different agencies, not
concentrated.
Therefore, building a mineral resource database to integrate in a
common management system is very necessary.
1.2. Research situation in the world and in the country
1.2.1. Research situation in the world
Many scientific works have combined remote sensing and GIS to
establish potential maps of mineral distribution or assess changes in
