Generating Information from Scanning Ohio Maps (GISOM) - This is a cooperative project among state agencies (OGRIP/DAS, Ohio Department of Development (ODOD), Ohio Department of Transportation (ODOT), Ohio Department of Natural Resources (ODNR), and Ohio Environmental Protection Agency (OEPA)), USGS, and The Ohio State University’s Center for Mapping. This project consists of scanning the 7.5-minute U.S. Geological Survey (USGS) quadrangles which encompass Ohio. GISOM creates vector information from scanned images. This vector information consists of boundaries, Public Land Survey Systems (PLSS), hydrography, hypsography and transportation.
The digital base map being developed by the GISOM project converts USGS’s 1:24,000 topographic 7.5-minute quadrangles into the Digital Line Graph-3 (DLG-3) format developed by the USGS. Subsequently, these data are entered into the National Digital Cartographic Data Base (NDCDB) as part of the public domain. The digital files are distributed by the USGS at the federal level, and the Ohio Department of Administrative Services’ GIS Support Center at the state level. DLGs for the entire state have been completed and are expected to be available in the fall of 1998.
Survey of Geographic Information Systems (GIS) in Local Government - The goal of this OGRIP-funded study was to acquire information about geographic and land information systems (GIS/LIS) development in local government agencies in Ohio. The results of this study look at local governments and describe the status of their system development and the forces for change in them. For the most part, local government was represented by Ohio county auditors and engineers who responded to the two questionnaires which contributed to the study. The results of this study are available through the OGRIP office.
Metadata Issues - OGRIP is researching issues associated with data documentation and data about data, referred to as metadata. As more data becomes available metadata will provide the foundation for data usage and sharing in the future. One of the projects associated with metadata is the “Spatial Metadata Software Evaluation” report. This project involves the examination, assessment, testing and evaluation of software processing tools for spatial metadata. Anticipated completion of this report is the summer of 1998.
OGRIP is also funding a Metadata Pilot Project. The scope of this project is the development of a metadata pilot to test the creation, dissemination and searching possibilities of metadata files using real world data. This work will result in the following:
- a real-world test of metadata collection tools;
- the creation of real-world metadata suitable for a state clearinghouse node;
- documentation of a process of creating metadata and posting files to a searchable site;
- a test of the creation of a clearinghouse site using text and/or relational database metadata files yielding information about problems and benefits of each file type; and
- an additional study of core metadata fields and how individual fields will be used in Ohio. The ultimate goal of this work is the promotion of statewide data sharing activities in and between Ohio organizations. Anticipated completion of the pilot is 1999.
National Digital Orthophotography Program (NDOP) - Ohio is participating in NDOP which will provide 1:12,000 scale, 1 meter pixel resolution, +/- 33-foot accuracy, 50 MB file size (compressed to 5MB), digital orthophotos covering _ of a 7.5-minute U.S. Geological Survey (USGS) quadrangle. The results of this effort for Ohio is a statewide digital orthophoto coverage with the above specifications.
Three federal NDOP partners, USGS, National Resource Conservation Service (NRCS), and the U.S. Farm Service Agency (FSA), as well as the Ohio Department of Transportation, Ohio Department of Natural Resources, Ohio Environmental Protection Agency, and the Ohio Department of Administrative Services (OGRIP) are cooperating in this 2.4-million-dollar initiative. The Federal government and the State of Ohio have agreed to fund 75% and 25% of the costs respectively.
While Digital Orthophoto Quarter-quads (DOQQs) fulfill obvious requirements for state agencies, they also provide significant benefits to the private sector, local governments, and regional planning commissions. Examples of these benefits are consistent coverage of large geographic areas, (statewide/ regional coverages, service boundaries, transmission and distribution corridors, floodplains, watersheds, etc.) and assistance in the identification of five- acre parcels or larger in the rural counties. Similar benefits are being realized in states participating in, and/or receiving data from NDOP.
OGRIP believes providing access to DOQQs will serve several purposes:
- provide a consistent base-map coverage;
- serve as an education tool for the use and application of digital orthophotos; and
- provide a spring board for GIS initiatives and cooperation. OGRIP is committed to this program due to the wide range of benefits to OGRIP’s membership.
The DOQQs will be made available through the GIS Support Website. Expected completion of this program is in the Fall of 1998.
State of Ohio Geodetic Advisor Program -The National Geodetic Advisor Program is jointly funded by the Ohio Department of Natural Resources (ODNR), the Ohio Department of Transportation (ODOT), and the Ohio Geographically Referenced Information Program (OGRIP) to establish geodetic control throughout the State of Ohio. This program provides much needed technical assistance to ODNR, ODOT, and OGRIP, as well as The Ohio State University Center for Mapping and local government regarding the planning, coordination, and implementation of pilot projects to continue the development of Multi-Purpose Cadastres (MPC). For more information on this project, please contact David Conner, Ohio Geodetic Advisor.
Higher Education Curriculum Study - OGRIP is collaborating with a consortium of Ohio universities in the development of a statewide GIS training curriculum for practitioners of GIS technology. The results of the survey contain three analyses concerned with how to provide specialized training in the use of Geographic Information Systems (GIS) for professional staff in Ohio. The analyses include: 1) an inventory of GIS training programs at Ohio’s universities; 2) an assessment of GIS training programs in other states; and 3) a survey of practitioners in Ohio. This study was funded by OGRIP and The Ohio Urban University Program. The results of this study are available through the OGRIP office.
Guidebook on Consortium Development - This is a research project working with Wayne County to develop a guidebook that can be used by other communities. The purpose of the study was to document institutional and organizational issues involved in establishing geodetic control and other foundational requisites for developing county compatible data. This study is currently under development.
