Our GIS is composed of many layers of information, Tax parcels, 911 road names and address, Flood data, Contour lines, Orthophotography, Full annotation, Symbols, District Lines, Hydrology, History layer, Topology and construction layers,
AssessedArceAnno- Parcel acreages were linked to the acreage field in the IAS database field. When we linked the acreages to the IAS were able to compare the old map acreages to the IAS acreages and found over a thousand instances were the acreages were different. This really helped clean up a lot of acreages discrepancies.
The base layer is the 2003 aerial orthophotography which is a picture of the ground and what is on the surface of the land. These photos have had the elevation distortion removed and have been fitted together into a seamless countywide coverage.
The WV Sheriff's Association currently has a contract to have the state flown leaf off this spring and fall. This should be some very nice orthophotography Not only will it be top down but it also will have oblique views of structures.
The more populous areas will be at 4 inch pixels and the rural areas will be at 12 inch pixels this project is to be distributed to all counties.
The 2003 photos are 36 inch pixels.
Assessors can contact their local Sheriffs department for availability.
The field workers wanted smaller maps to work with 18 X 24 instead of the 24 X 36 copies. We also added what is called a shadow layer which is a light colored area around the map which shows adjoining parcels to the subject map.
Information displays with a click of the mouse on the parcel of interest.
The Identify box displays the ownership information of the parcel. Map and parcel number, acres in parcel, address of owner, deed book and page, legal description and other information in the database which you can control.
We also use the GIS to querry information in the IAS database. Such as find all parcels say larger than 1 acre but less than 5 acres. Find all parcels in neighborhood 12. Find all parcels that are vacant and greater than 50 acres.
. You can querry on any information that you have downloaded from the IAS into your database. It can be a very simple querry or a very complex querry with multiple variables In it. Such as find all parcels in Lubeck District with single family dwellings that are more than 5 acres less than 10 acres and are in neighborhood 21 and are within 1 mile of the Junior High School. Your knowledge, imagination, and information in the database are the only limits of your queries.
Do the same on the taxable field and research the ones that come up null, then check the tax exempt parcel to see if any should be taxable while doing this you can symbolize Churches, School, Libraries, etc on the map. All Parcels that require symbols are tax exempt. This really makes finding these parcels easy.
You can use Microsoft office access to run mismatch files to determine parcels that are on the map but not on IAS or on IAS and not mapped we had several of these both ways in most districts. These searches will really help to clean up your maps and IAS.
We also have our GIS deployed on the internet by Kimball Corp. with a link at our county web page. Many of the professionals in our county use this web site such as Lawyers, Real Estate Appraiser, Realtors, Developers, Timber
. People will call in from local or out of state wanting to see maps we will direct them to the web page. If they want we can make a JPEG file of their area and e-mail it to them. We have had a noticeable drop in the traffic to the map room because of the web site.
As I was working on this presentation a gentleman working for the Censes bureau came in wanting to know what houses had been demolished for the new RT 50 by-pass. I put him on our web site and he was very happy with that and it save me quite a bit of time.
