The recent new developments for updating the user interface (UI) of the Black Sea oceanographic database are described in the current work. The developments dedicated to the use of new techniques at the base of WebG, for the visualization of the Black Sea oceanographic data and the online data access functions and features. The updated Black Sea oceanographic database is realized in two parts using the postgresql. The first part of the database, which is responsible for accessing the metadata was designed and developed for interactive transaction processing (OLTP access template). The second part, which is responsible for the in-situ data archiving was developed following the "star" architecture. The latter is typical for the OLAP access template. The selection of the WebGL for the updated Black Sea UI is based on the advantages in using the modern technology for data visualization and analysis. The WebGL provides fast visualization of geographic objects at the user browser using GPU. Therefore, the previous implemented Mapserver for the Black Sea oceanographic GIS has been abandoned in favor of the WebGL. The updated UI of the Black Sea Oceanographic database includes a main menu, providing access to several online friendly user functions. The UI provides access to the data through several filters/criteria, such as the cruise name, date of cruise, ship name, sea area, hydrological and hydrochemical parameters, etc. The selected data are provided in the form of maps, profiles and metadata.

This paper illustrates how BIM integration with GIS is approached as part of the workflow in creating Virtual Historic Dublin. A design for a WEB based interactive 3D model of historic buildings and centres in Dublin City (Virtual Historic Dublin City) paralleling smart city initiates is now under construction and led by the National Monuments at the Office of Public Works in Ireland. The aim is to facilitate the conservation and maintenance of historic infrastructure and fabric and the dissemination of knowledge for education and cultural tourism using an extensive Historic Building Information Model. Remote sensing data is now processed with greater ease to create 3D intelligent models in Historic BIM. While the use of remote sensing, HBIM and game engine platforms are the main applications used at present, 3D GIS has potential to form part of the workflow for developing the Virtual Historic City. 2D GIS is now being replaced by 3D spatial data allowing more complex analysis to be carried out, 3D GIS can define and depict buildings, urban rural centres in relation to their geometry topological, semantic and visualisation properties. The addition of semantic attributes allows complex analysis and 3D spatial queries for modelling city and urban elements. This analysis includes fabric and structural elements of buildings, relief, vegetation, transportation, water bodies, city furniture and land use.

The paper briefs on the improvements of the Black Sea oceanographic GIS, which is developed for the needs of the Marine Hydrophysical Institute (MHI) oceanographic database. The structure, data and the online data access technology for the existing oceanographic GIS at MHI were described in "Black Sea GIS developed in MHI" [1] and "Using GIS technology for access to coastal data" [2]. Currently, a geo-spatial database has been implemented in order to improve the Black Sea oceanographic GIS. For this purpose the postgresql/postgis database has been used, taking the advantage of its high functionality and open source. The structure of the new Black Sea oceanographic GIS database has been developed following the SeaDataNet metadata and data standards. The new improvements include the development of scripts for data exchange between the User Interface (UI) and the postgresql/postgis database. Furthermore, instead of the previously used Flex RIA, the HTML5 is implemented to avoid problems concerning the support of new browsers. The main functions of the UI are realized using jQuery, while the Mapserver services are realized using OpenLayers.
