Introduction
For many organizations and professionals (we'll call them geospatial users) in Bulgaria geospatial data is crucial. From planning through design, construction, and maintenance, these geospatial users needs data interoperability and a fully integrated platform for managing geospatial data assets. It's essential that these geospatial users have the tools to take full advantage of all their geospatial data and geospatial information, which is typically stored in a variety of locations.
On the other hand everything has to be in accordance with current operating regulations for access and management of geospatial data. In the following we consider national operating regulations for:
* Conversion of existing geodetic and cartographic materials and data in Bulgarian Geodetic System 2005 (BGS 2005) [1], [2] and
* National formats [2] for storage and distribution of geospatial data - ZEM format for storage data in the Ministry of Agriculture and CAD format for storage data in cadastral map. ZEM format, contains the structure of the record of the Map of the Restored Ownership over agricultural and forest areas and registers to it. Last actual version 3.03 from 28.03.2103 [3]. CAD format or Format for the exchange of cadastral data [4], contains the structure of the digital record of the cadastral data. Last actual version 4.02 from 16.06.2105 [5].
So, important is the question - What geospatial solution is appropriate to geospatial users that manage geospatial data assets?
Methods used
The response to the question above means geospatial platform in accordance with operating regulations for access and management of geospatial data.
The geospatial platform provides a suite of well-managed, highly available, and trusted geospatial data, services, and applications. As a geospatial platform we'll consider Autodesk Aut°CAD Map 3D software - model based GIS and mapping software [6].
The compliance with current operating regulations for access and management of spatial data is achieve in Aut°CAD Map 3D software through:
* Third-party software modules (projects) created with Microsoft Visual Studio
* Coordinate System Library to create and assign BGS 2005 from within this library
* Cloud-based collaboration software Autodesk A360 desktop to view, search, and share data in the cloud using desktop, web and mobile device
* Built-in Geolocation feature to work with Bing Maps geocoding and map data
In the rest of this poster we'll focused on this compliance.
Third-party software modules to access and manage geospatial data in model-based GIS and mapping software
In compliance with the above mentioned operating regulations for access and management of geospatial data in model based GIS and mapping software, it needs to be available or realized the following functionality:
* Introduction and subsequent intended use (consistent with maintaining data model), data from ZEM format to maintain the data of the Ministry of Agriculture over agricultural and forest areas and registers to it (i.e. files with the extension ·. ZEM)
* Introduction and subsequent intended use (consistent with maintaining data model) of data from CAD format for the exchange of cadastral data (i.e. files with the extension ·. CAD)
* Transforming geospatial data and subsequent use as intended, to/from all the country used coordinate systems and projections (directly supported from maintained data model according created digital model of the territory - situation and/or relief)
* Work with interactive maps
The above mentioned functionalities are realized by the author in the form of modules for specific model based GIS and mapping software:
* Converting data from ZEM/CAD files
* Transformation of graphical objects according used in the country coordinate systems and projections
* Working with Bing interactive maps
The modules are compatible with the following Autodesk Aut°CAD based softwares (part of the package Autodesk Infrastructure Design Suite): Aut°CAD Map 3D, Aut°CAD Civil 3D, Aut°CAD Utility Design. In an environment of "pure" Autodesk Aut°CAD functionality is limited when converting data from ZEM / CAD files.
The modules are designed as panels in the Ribbon bar "Конвертор" to the appropriate workspace (Fig. 1)
The functionality of the modules will be presented with the help of ZEM file for the territory of village Plenimir, Region Dobrich (North-East Bulgaria).
Functionality module for converting data from ZEM/CAD files:
* Works entirely in corresponding Aut°CAD based software with menus in Bulgarian
* 100% compatible with supported data model in relevant Aut°CAD based software for accessing and managing geospatial data
* The conversion is performed through sequential steps (Fig. 2)
* After conversion all attribute data are structured in tables with built relations in · .mdb format by default (do not require MS Office) or Enterprise-class relational database system like Oracle, Microsoft SQL Server, MySQL
* Realize bilateral relationship between graphical objects and attribute data. The transfer of attribute data and the link to graphical objects is accomplished automatically
* Works with and without topology. When working with topology - for layers LESO and CADASTER (from ZEM file) and layer CADASTER (from CAD file) polygon topology is automatically created. Valid polygon topology allows formal assessment of data quality
* Enables implementation of various applications for visualization and reports (fixed and user-defined) from a database established (Fig. 3)
Functionality module transform graphical objects according used in the country coordinate systems and projections:
* Works entirely in the corresponding Aut°CAD based software with menus in Bulgarian.
* 100% compatible with supported data model in Aut°CAD based software for accessing and managing geospatial data
* The transformation of graphical objects between different coordinate systems and projections apply to graphical objects (primitives) from Aut°CAD database using (set/change) the current coordinate system (Fig. 4) or assign a target one (Fig. 5)
* Apply official transformation parameters and transitions according to operating regulations [2]
* After transformation, all graphical objects are in DWG format fully preserving the structure of the user
* After transformation module store information about the current coordinate system (Fig. 4)
Functionality module work with Microsoft Bing interactive maps:
* Used platform Microsoft Bing Maps (Fig. 6)
* Works entirely in corresponding Aut°CAD based software (Fig. 7)
* Automate work with Microsoft Bing Interactive maps (Fig. 8 and Fig. 9)
Key role in this geospatial platform play supported from Aut°CAD Map 3D - FDO technology and Industry models. With the latest we can talk for a comprehensive geospatial technology.
FDO or Feature Data Objects is data access technology [7]. FDO supports the creation of data store neutral applications and makes it easier to exchange information. The underlying technology is based on open standards, so it eliminates many of the difficulties commonly encountered when working with proprietary systems. FDO is the Autodesk software standard and general purpose API for accessing features and geospatial data regardless of the underlying data store.
Industry model [8] is a specialized schema stored in an Oracle or Microsoft SQL Server database (an enterprise industry model) or in a drawing or template file (a file-based industry model). Industry model contain feature classes, rules, relationships, and other settings (like forms, reports, analysis tools, workflows). Aut°CAD Map 3D offer five predefined data models - ELECTRIC, WATER, WASTEWATER, SURVEY and GAS industry models. The predefined data models are adapted in conformity with operating regulations. User can create, edit, and configure industry models using the Autodesk Infrastructure Administrator - configuration module to set up and manage projects and industry models. Besides, we create special (3rd party) industry models - CADASTRE, SPATIAL DEVELOPMENT, BIOTA/ABIOTA/INFRASTRUCTURE NATIONAL PARK CENTRAL BALKAN.
CONCLUSION
Presented solution integrate Autodesk Aut°CAD Map 3D as model-based GIS and mapping software with 3rd party software (modules) in accordance with operating regulations for access and management of spatial data. The solution brings leading geospatial technologies (such as Remote Sensing, Geo Information System, Global Positioning System, Internet Mapping) together to help organizations get the full value from spatially enabled data, such as:
* Direct access to geospatial data natively stored in a databases (such as Oracle, ESRI ArcSDE, Microsoft SQL Server, ODBC, and MySQL), file based data stores (such as Autodesk SDF, ESRI SHP and raster), or a direct connection to web services (such as Web Feature Service for vector data and Web Map Service)
* Publish and share CAD, GIS map, and asset information with web based GIS mapping software
* Natively access to CAD, GIS, point cloud imagery and business information from a broad range of sources without the inherent risks of data conversion
* Analyze data for better insight to into existing conditions and the potential impacts of future projects
* Apply intelligent industry models to better organize information
* Effectively share more coordinated and consistent information
* Helps surveyors, architects, planning and engineering professional access evaluate and share data to make more informed decisions
Presented modules expand the functionality in Autodesk model based GIS and mapping software ensuring the necessary interoperability in accessing and managing geospatial data according operating regulations.
Important practical point of view for implementation projects to support planning, design, and data management and directly related to the access and management geospatial data, is the fact that in June 2015, the Agency for Geodesy, Cartography and Cadastre (AGCC) perform transformation of the cadastral map from coordinate system 1970 (zones K-3, K-5, K-7 and K-9) in BGS 2005. This happened as a result of the implementation of Government Decree ? 153 of July 29, 2010 to introduce "Bulgarian Geodetic System 2005"[9].
