Although many facets of AM/FM/GIS have been successfully implemented, work order generation and work order processing seem to be lagging behind. Work order generation in a GIS environment is complex and raises some data integrity issues that do not concern other areas of the GIS. Work orders, by their very nature, indicate that the GIS data is not static, but rather a "living organism" which requires constant maintenance -- a challenge to all those charged with maintaining accurate data. The work order process will be discussed, analyzed and demonstrated, in principle. In addition to generating work orders, a tracking mechanism must be initiated and integrated into the enterprise GIS to complete the work order to as-built, completing its life cycle. Again, addressing the issue of maintaining data integrity as entity states are changed and data are added to the corporate assets. In this session, the work order will be presented as the tool by which the enterprise GIS is fed and maintained while allowing interdepartmental access to the data by planning, forecasting, engineering, records, accounting, right-of-way, construction and others.
As GIS technology is developed, GIS data transfer is needed to support various GIS users. As the Korean GIS infrastructure is being developed, National GIS was being constructed in Korea, and in terms of NGIS in Korea, the GIS Data Exchange Standard Subcommittee was constructed. Korea Telecom and CADLAND proposed the Korea GIS Transfer Standard, which is developed based on SDTS as a draft in August 1995. Because the current domestic knowledge and techniques about transfer standard were low in Korea, although demand for transfer is growing in Korea, the National Transfer Standard is needed to use existing transfer standards. In the process of establishing the Korea transfer standard, several steps were taken. First, we surveyed the existing GIS software in Korea to identify and review the GIS users. Second, after surveying GIS software, we reviewed GIS software data formats to check the common properties of GIS data formats. Third, existing data transfer standards were surveyed to determine which standard is appropriate for establishing the Korea GIS transfer standard. Through the previous three steps, we determined the SDTS as a proven standard. The reasons why SDTS was selected from existing standards were general aspects and specific aspects. Regarding general aspects, SDTS has four major categories as a transfer standard; that is, generality and general purpose, open system-based, integration and harmonization, and interpretability, extensibility. Regarding specific aspects in Korea, we focused on four issues: current domestic requirement (National GIS infrastructure), harmonization among various domestic interests, proven stability acquisition, and coordination between international and national standard activities. After choosing SDTS as an adopted standard, we took the next steps; that is, user need assessment, to modify SDTS as an appropriate Korean standard. In this step, we reviewed and analyzed the framework, structure, data model, and data dictionary in SDTS, and we collected the various interests of GIS users. After this process, we modified two parts in SDTS: the data dictionary and coordinate system. During the evaluation procedures, ArcInfo's SDTS export/import commands were tested, and the conversion process was more than adequate when we have tested it with Korean characters for annotation and database text. Regarding data dictionary modification, we compared the SDTS data dictionary (as a part 2) with the Digital Mapping Guideline of NG (National Geographic Institute) in Korea. To construct the proper data dictionary as a standard, we referred to various existing data dictionaries nationwide such as National Geography Institute, Agency for Defense Development, and other provincial governments. After modification in the data dictionary and coordinate system, we established the detailed implementation method. Through several steps, the Korean GIS transfer standard was established, and this draft was submitted to the GIS Data Exchange Subcommittee of NGIS. On 7 December 1995, the SDTS-based Korea GIS transfer standard was adopted as a National Transfer Standard (KIS0000 (95) W).Now we are preparing the complete National Transfer Standard through the sophisticated modification process, and have the plan to support the physical conversion process between the standard and various GIS software.
