As a result of GIS Day November 20, several schools took
advantage of the offer of a set of CDs containing the digital orthophotography
Class C concrete monuments have been set at the Lloydsville
Garage and at Nelson Field, Bellaire, thanks to help from Carey Greco, Buckey
Thornton and Don Buonamici. Berntsen’s
bronze 4 inch diameter markers, stamped “Belmont County Engineer - Geodetic
Control”, will be grouted into the tops of the monuments. These monuments will be observed next spring
as part of NGS’s reobservation and establishment of a new datum. In November a monument was also set by the
A dual-frequency GPS receiver was delivered this month. The Ashtech Z-Xtreme unit will be used to observe the above-mentioned monuments. It will also be used in the process of getting positions on existing section corners, and other points, to help with better orienting digital tax mapping. I tried the unit out by setting it up on a water shutoff and getting four hours of static observations. The data was downloaded to a notebook computer, zipped and submitted online to NGS’s OPUS site. Within a few minutes, an email was received giving specifics about the point’s location. Pretty slick!
We now have single-file countywide coverages for buildings, hydrography, centerlines and 10’ contours, thanks to Stanley Wong and John Antalovich, Jr. of Kucera International. We appreciate their willingness to create these layers. The contour layer is the largest, at over 800 MB in file size! These files have been copied to the E-911 server and distributed to the Sanitary Sewer and Engineer Departments.
Some more features have been added to the house numbering
program to facilitate consistent data entry.
Drop-downs for road name, road type, community and township make for
more consistent data. Emergency service
number lookup was also added to populate police, fire and

GIS Day, an annual worldwide event, was November 20 this year. Governor Taft declared GIS Day in
On November 14, the county’s parcel data went online. John Parkinson covered the development of this project in a previous newsletter. The public access computers in the tax map room were converted to the new program this week. Parcels can be queried by name, parcel number, property address, owner address, and section. Results show name, Auditor parcel number, Engineer parcel number, deed volume and page, subdivision with Cabinet and Slide (if applicable), addresses and land and improvement values. Thanks to Jason and Jim II Davenport of Draft-Co for agreeing to host the data on their server and for a speedy setup. John is uploading the data from his office to the server, and will probably do so on a weekly basis. The recorded plats are also available at the GIS web site (www.belmontcountyohio.org, County Departments), and these online files have been updated this month as well.
the ESRI Workshop at this year’s 12th Annual Ohio GIS Conference in
At the Professional Land Surveyors of Ohio Fall Seminar, ESRI’s Survey Analyst was demonstrated. This package will be included in the next release of ArcMap 8.3. Other PLSO sessions included ethics, charm school for surveyors, writing deed descriptions and robotic surveying. Stu Davis of OGRIP, Dave Conner of NGS and Dave Albrecht of ODOT also updated surveyors on geodetic control work scheduled for next year.
Permission was granted by the Bellaire Board of Education October 14 for installation of a geodetic control survey monument on school property. The monument will be placed within a month, and observed next Spring using GPS technology.
We have asked Kucera International to create seamless countywide coverages for planimetric features, and possibly contours. Data is currently in .e00 format by 5000 foot square tile, and there are 681 tiles that cover the county. Building outlines that span one or more tiles are represented by separate polygons. A countywide coverage will result in each building being represented by one polygon. Similarly, centerlines, streams and lakes will be joined. Delivery should occur within another week. At that point we can begin assigning house numbering data.
Ohio Utilities Protection Service has asked for mapping data to improve the
accuracy of road centerlines in
National Geodetic Survey (NGS) and the Ohio Geographically Referenced
Information Program (OGRIP) have held four workshops this month in the four
quarters of the state, with one more workshop planned for central
September 12 I visited Kucera International’s office in
On September 10 a GIS update was given to the 911 Board at their monthly meeting. House numbering and building outlines were the focus, and a new database interface was shown for rural house numbering. I also presented to the Martins Ferry Rotary September 16, where I had an opportunity to speak with Rotarian and former Belmont County Department of Development Director Don Myers. Don expressed his support for the GIS program, and wished he had the information he saw that night when he was Director here.
Recorded plats are now available online! I have often thought of the muffled groans I heard when I was still in the courthouse made by those who were asked to make a copy of a recorded plat for a customer. Plats are stored in the Recorder’s Office one floor up, and making a copy necessitated a trip upstairs, bringing the one and only official copy downstairs, copying the plat, returning the original, and getting the copy to the customer. Now the public and employees alike can access the plats in pdf format on the web. I added pages to the GIS web site that link to files placed in additional storage area provided by FirstNet. Files are organized by Cabinet and Slide, and the plat names are listed for reference. Give it a try at www.belmontcountygis.com. And let me know of any missing or incorrect links.
On September 18, MRT, Inc. demonstrated their pilot project mapping area to the Belmont County Commissioners during a regular meeting. Mark Toalson showed census, soils, flood zone and fire hydrant data with parcel data, planimetrics and orthophotography for the one square mile area. Derrel Owens demonstrated a public access front end for easy access to owner information and mapping. Commissioner Chuck Probst asked about the availability of county water and sewer data for the system. Currently that data is not in digital format. This was the focus of a presentation to the GIS Committee by Woolpert LLC on August 15, outlining inventory methods for collection of data for water and sewer infrastructure. Thanks to the Commissioners for the opportunity to present a GIS program!
On September 20 the Belmont Soil and Water Conservation District held their 5th Annual Legislators’ Tour. The GIS office was packed with people who saw sample mapping in the Barnesville area, and a demonstration by Jeff Bittenger, NRCS Lead District Conservationist, on farm plan mapping. They use ArcView for showing field tile locations, fencing projects, and buffer zones around creeks. Beverly Riddle, District Program Administrator, mentioned the need for updated tax maps in digital format to facilitate farm plans, especially with the high number of property transfers in coal company areas. The interest in the county’s GIS was overwhelming, and we thank them for making us a part of their tour.
A web-based database program has been written for public access to parcel data. We are looking at installing the software on public access computers in the Engineer’s Office in the near future, replacing the DOS-based software currently in use.
A GIS update was given to the Belmont County Township Association August 1, showing digital orthophotography and announcing availability of CDs. A tentative date is in the works for a demonstration at an upcoming Commissioners meeting.
Kucera International has now delivered all building outline, hydrography and transportation centerline planimetrics. They tell us that the balance of all contour data will be delivered during the course of this month.
Work has begun on the county house numbering database so it can be attached to planimetric data. Woolpert LLP gave a presentation August 15 on water and sewer infrastructure inventory and mapping. Aerial photo enlargements from 1950 have been compressed to Adobe Acrobats’s pdf format, and are available on one CD. Also, all the recorded plats have been compressed from tif to pdf format, and fit on one CD as well. And finally, the Ohio GIS Conference is coming up next month, September 25-27, in Columbus.
Note: It was two years ago, August 9, 2000, when the GIS Committee appeared before the Commissioners and recommended the establishment of the GIS Department.

The digital orthophoto CDs are being duplicated! Cost is $35.00 for countywide coverage, or $5.00 per CD, for pickup at the Engineer's Office; shipping and handling will be added if you want them mailed to you. There are six CDS which cover the county at one foot pixel resolution. Each image covers a 5000 foot by 5000 foot area. A seventh CD covers the non-rural areas - Barnesville, Bellaire (including St. Joe and Neffs), Belmont, Bethesda, Bridgeport, Brookside (including Wolfhurst, Lansing and Blaine), Flushing, Martins Ferry, Powhatan Point, Shadyside, St. Clairsville and Yorkville - at one-half foot pixel resolution, 2500 foot by 2500 foot. Images are in color and are in MrSID format at 20:1 compression, NAD 83(95) datum. ArcExplorer is included on each CD, which you can install on your computer to view the images.
All of the digital orthophotos have been received in tif format. We have 86 CDs at 1"=200', and 20 CDs at 1"=100' for a total of 106 CDs. Kucera is now compressing the images using MrSID by LizardTech. There will be a 20x compressed file for each township, and a 40x compressed countywide image. About 90% coverage has been delivered for road centerlines, building outlines and hydrography. The Engineer's Office has been creating files by township for these layers in AutoCAD Map.
I attended an OGRIP outreach meeting in Stark County June 24. Brent Winslow, PS, of the Stark County Auditor's Office GIS, presented a very interesting explanation of section corner and quarter section corner recovery and restoration. Staff research survey maps, field books and deeds for section corner references. Then field reconnaissance is done. Corners in poor condition are restored with a new monument, and then corners are GPS'd. The 17 townships are in the rectangular survey system, and it is anticipated the 2000+ section corner and quarter corners will be monumented by 2010.
A GIS demo was given at the Flushing Ruritan July 1. A large crowd saw images of downtown Flushing and the pilot tax map area in Goshen Township. Thanks to Ty Justice for the invitation to speak.
Fire hydrant locations were gathered for the pilot tax map project in the Bethesda area. MRT will give a presentation of the final product to the GIS Committee at its next meeting July 25 at the GIS Office. Included will be parcel mapping and database linkage, sample parcel card and survey maps, orthophotography, road video, bridge info, railroad and highway plans, watershed area, and coal seams.
We have now received 188 images of digital orthophotography for the county. This makes a 23% delivery of about 815 images for the entire county. Contours for some areas have been received as well.
A pilot tax map conversion project has been initiated. About 1200 parcels will be mapped and data-linked in the Bethesda municipal area. Paper tax maps and other data are being scanned and forwarded to Map Research Technologies, Inc. The mapping area includes a state road, county road, township road, municipal streets, subdivisions, and an abandoned railroad. Anticipated completion is mid-summer.
The second annual Tax Map Workshop will be held in Columbus May 21-22. Each county in the state has been asked to provide a tax map for display at the workshop. This should make a very interesting exhibit. To all the County Engineers – make sure a tax map from your county is sent to OGRIP, 77 S. High St., 19th Floor, Columbus, Ohio 43216 by May 10.
I have begun attending CEAO’s Surveying, Mapping and Land Records Committee. Chair is Coshocton County Engineer Fred Wachtel. The April 11 meeting included informative discussion about geodetic control. The Ohio Valley and Muskingum Chapters of PLSO may arrange a joint meeting so this topic can be explained by Dave Conner of NGS and Dave Albrecht of ODOT, who are willing to travel to PLSO meetings for this purpose.
I gave a short GIS presentation at the Engineer’s Annual Township Trustee meeting April 3. I also spoke at Career Day at St. John Central High School April 12. On May 3 I will give a presentation at the annual employee’s meeting, and also May 7 at the St. Clairsville Rotary lunch meeting. See you “on the road.”
We have begun to receive digital
orthophotography on a regular basis in the last month from Kucera
International, Inc. Images have been
received for the northwest part of the county, in addition to images for the pilot
project of about four square miles in the Bethesda/Goshen Township area. The color images are in tiles and take about
73 Mb of disk space each. We will
evaluate compression ratios using MrSID software from Lizardtech, and have
received samples from Kucera in 10x, 20x and 30x ratios. The tiles are square, 5000 feet on the side,
with one foot pixels. In the more
populated areas, tiles are 2500 feet on the side and have a resolution of ˝
foot pixel. The tile grid is based on
values from the State Plane Coordinate system for
Status of Countywide Mapping:
Kucera International, Inc. estimates that it will be the end of May, 2002 before the countywide mapping project is finished.
The GIS Office has moved to its new location. On February 1 almost all equipment and furniture had been moved and set up. The new phone number is 740-526-9306. The office is located in the new garage on US 40 at Lloydsville, 1.5 miles west of the intersection of SR 331 and US 40.
Global Positional System (GPS) training was conducted January 23 at the courthouse. Mike Wahl, John Parkinson, Tom Fulton Judy Jenewein and myself watched as Bob Busch of CompassCom instructed us in setting up a job with the accompanying Pathfinder software. We then went outside and mapped some points, lines and areas. Upon returning to the office, we downloaded the job and performed postprocessing using data from the Internet. An ArcView shape file was created and viewed over existing digital ortho photography.
The Ohio Valley Chapter of the Professional Land Surveyors of Ohio met January 24 in the tax map office. They plan to establish a latitude/longitude monument on the St. Clairsville bike path this spring. Dennis Bigler, Service Director for the city, agreed this would be a good public service activity. The Chapter covers six counties, and intends to set a monument in each in the future.
We received the aerotriangulation report from Kucera International. They are still processing the digital mapping data and have not sent any deliverables yet.
I made a trip with Dick Quinlin and company January 10 to the state surplus warehouse in Columbus, where I found a couple of cabinets for the new GIS office. I enjoyed riding with computer-guru Sgt. Dave Lucas of the Sheriff’s Office, and talking about GIS applications for their department.
Finally, thanks to Chuck Malolepszy of Austen Surveying for the compliment regarding the section maps on our web site:
Thanks for the digitized maps -- they will be a valuable tool for us.
A little encouragement once in a while goes a long way.
