but the and quoting here because this is
came currently must have I'm sorry with given this is certain Krontiris studying for a Masters course the subject and the University and I will be presenting and that they belong the development that through the base of the mines monitoring system the
content is our contention that as shown on that on the table of contents I like to start to read the
summary of our research the but
after 9 our topic that would interest are crucial infrastructure to industries they should however be continuously monitored as they also impose environmental and ecological treat to their reasons this research therefore focuses on Disney the 4 on monitoring system and develop someone that is able to Major and detect change all of the mind spurted of cross gone reasons we the use all future geospatial in in formation opened weapon and often so software does our optimistic for this research was to contribute to the ecological restoration of all the commands the
research is supported by nature Research Foundation of Korea and we're on our 2nd year old the project In the 1st year within minor classified into different sectors monitoring nestled are established and system development environment is set up this here being the 2nd year the research has been focusing mainly on establishing they have order monitoring establishment or or database for acknowledging consist of collecting data from the from there so this will the website and you neurocrine high resolution EEG and the and this data then combined into a single framework that operates In the last year does system design and prescribed established in 2nd year will father developed in mid GIS of 2 rear based on open source next use on Chris file from the mine in establishing concept on all of the mind monitoring
there are still still further from cement mining gonna reason of those 90 have are lies basic data and information to divide them into Active or opened to mine and met in mind the around were in use all those line for minded compared to the scale including Alappuzha as in mind were selected the subject that kid my for monitoring while billions into was chosen as neck Ch
the concept and monitoring concerning the meaning of an the concept of emerging concerning off mineworkers fighting tool or operational aspects and environmentally close prospects for the play will put us that consists of mining area equals for restoring area he just a restoring area the environmental ecological aspect consist of easterlies area and ecological restored areas methodology on the at present day out selection or according to monitoring area and is upgrading means are also set the
figure you some of subdivided monitoring area although on active mine La Paz Osman mind this new stuff 2 dimensionality she's on the resort to using different muscle so the meat or Sigel operative from Alabama disobeying on 2007 and 2014 the figure are
flooded the bizonal was monitoring area in 2007 and 2014
and this the figure is oxygen a monitoring area with residue RBM greatly the by neither the M operator from a urban later so banging 2007 and 2014 next is the construction of a database and use upgrade the for monitoring system furthermore turning
all often the minor mass so the Ricci efficiently detects change over time is needed In this research test that relational database for the margin system there collection and they are upgraded with new data or pollution to place the application process you close to questionable time and they and Ingersoll based by Jews special information open flat and all of them they are so this from the public and private or website they have a subway the process conses consistent to difference in the so the walker data periocular shimmied airborne laser something and then theory for collision at the UAB system or test your hideout for Argentina urgencies this collected data is combined it amid association they have been to create ofuse database for the monitoring system the collection is
a series of a collection of at the they and also images serviced by open their summers but for like other harassment minding image data consist of a biennial Open Data from favorite site and then GII initial image you need a deform so these while at the time they playing there is based on the and they are provided provided by tissue platform and Ng II and US Gs the energy entering
their provided by Ossetian Villepin from database is not enough for the monitoring with the mind transitions so this research as if acrid odor data up you equally in 2007 and 2014 using airborne majors so being for . 0 database upgrade overlap as a lesson in mind this occlusion of data made it possible but upgrade of the database to be the source image of a ground sample distance 0 . 2 5 meter in their own little on the order of criticize all of 1 meter
also the heavily utilized terrestrial either system for situations such as the gesture that need non fury upgrade all that the database terrestial i . 4 billion for smuggled data up poker focusing on mining slope you the more than 80 degrees was utilized in the urban light up yeah In cases over the gestures such as cost and the corresponding flow after solider use used to grasp the situation or to plow restoration for the area this
research has utilized ommended the Arab ecosystem as of muscle to operate a database the figure shows here he is also unique genes and efficient collaborative will the database obtained from monitoring area oldloc pozzolan-cement we really has the John or coercive the occuring data work out a means for his time of convenience and such as shown in the
Figure collected and EEG and training data are established in time series and combined it me that database overseas your those geospatial information platform constricting the integral database
this is the process registration awoke rigorously image on the monitoring system database margin system based on scission using major provider after registering onto GeoServer this is the figure reached

Abstract Large-scale open-pit mines are critical infrastructure for acquiring natural resources. However, this type of mine can experience environmental and safety problems during operations and thus requires continuous monitoring. In this study, a web three-dimensional (3D)-based monitoring system is constructed using open-source geospatial information software and targeting the open-pit mine in Gangwon-do, Korea. The purpose is to develop a monitoring system of open-pit mines that enables any person to monitor the topographic and environmental changes caused by mine operations and to develop and restore the area��s ecology. Open-pit mines were classified into active or inactive mines, and monitoring items and methodologies were established for each type of mine. Cesium, which is a WebGL-based open-source platform, was chosen as it supports dynamic data visualization and hardware-accelerated graphics related to elapsed time, which is the essential factor in the monitoring. The open-pit mine monitoring system was developed based on the geospatial database, which contains information required for mine monitoring as time elapses, and by developing the open-source-based system software. The geospatial information database for monitoring consists of digital imagery and terrain data and includes vector data and the restoration plan. The basic geospatial information used in the monitoring includes high resolution orthophoto imagery (GSD 0.5 m or above) for all areas of the mines. This is acquired by periodically using an airborne laser scanning system and a LiDAR DEM (grid size 1 m �� 1 m). In addition, geospatial information data were acquired by using an UAV and terrestrial LiDAR for small-scale areas; these tools are frequently used for rapid and irregular data acquisition. The geospatial information acquired for the monitoring of the open-pit mines represents various spatial resolutions and different terrain data. The database was constructed by converging this geospatial information with the Cesium-based geospatial information open platform of the ESRI World Imagery map and with SDK World Terrain meshes. The problems that resulted from the process of fusing aerial imagery and terrain data were solved in the Cesium-based open source environment. The prototype menu for the monitoring system was designed according to the monitoring item, which was determined by the type of mine. The scene of the mine and changes in terrain were controlled and analyzed using the raster function of PostGIS according to the elapsed time. Using the GeoServer, the aerial imagery, terrain, and restoration information for each period were serviced using the web standard interface, and the monitoring system was completed by visualizing these elements in Cesium in 3D format according to the elapsed time. This study has established a monitoring methodology for open-pit mines according to the type of mine and proposes a method for upgrading the imagery and terrain data required for monitoring. The study also showed the possibility of developing a Web 3D-based open-pit mine monitoring system that is applicable to a wide range of mashup service developments. Acknowledgments This work was supported by the National Research Foundation of Korea (NRF) grant funded by the Korean Government (MSIP) (NRF-2013R1A2A2A01068391).
