  • Wood County Parcel Mapping (2010)

    1. 1. <ul><li>JPEGSgisdef.gif </li></ul>
    2. 2. Scanned Map <ul><li>Paper maps have no data attached to them other than what is written on them. </li></ul>
    3. 3. GIS <ul><li>How does this GIS relate to the Assessor’s Office? GIS has a multitude of uses in the assessor’s office. </li></ul>
    4. 4. GIS in the Assessor’s Office will <ul><li>Clean up maps and IAS </li></ul><ul><li>Quickly find any parcel </li></ul><ul><li>Help people more efficiently </li></ul><ul><li>Cut down on office traffic </li></ul><ul><li>Print better maps </li></ul><ul><li>Pick up property that is not assessed </li></ul><ul><li>Determine parcels in the 100 year flood plain </li></ul><ul><li>Quickly find adjacency containment & proximity </li></ul>
    5. 5. GIS Geographic Information System <ul><li>What is GIS in the Assessor’s office. </li></ul><ul><li>Tax Maps overlaid on aerial orthophotography. </li></ul><ul><li>Tax parcels linked to the IAS database </li></ul><ul><li>(Intelligent maps) click on parcel for owner info. </li></ul>
    6. 6. GIS layers <ul><li>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, </li></ul>
    7. 8. Map layers <ul><li>Anno General </li></ul><ul><li>Opens up into eight separate layers that toggle on and off </li></ul><ul><li>Boundary- Municipally and District lines text </li></ul><ul><li>Dimensions- lot line distance and directions. </li></ul><ul><li>Anno_misc- For miscellaneous text that doesn’t fit into any of the other layers </li></ul>
    8. 9. Map layers <ul><li>Hydrology- streams, lakes and rivers text </li></ul><ul><li>Lot Numbers </li></ul><ul><li>Railroad Names </li></ul><ul><li>Road Names </li></ul><ul><li>Parcel Numbers: We have our map number/ parcel number on the maps </li></ul>
    9. 10. Map#/Parcel #
    10. 11. Symbols <ul><li>Bldtypes layer- Symbols for Cemetery, Library, Airport, Church, Hospital, Post Office, Fire Station, and School. </li></ul>
    11. 12. Symbols
    12. 13. Acreages <ul><li>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. </li></ul>
    13. 14. Acreages <ul><li>The linkage also caused some problems so they are now unlinked but it is well worth doing till you clean them up. It is very simple to unlink this field. </li></ul><ul><li>If we did a split after July 1 st when we relinked to the new years file the acreages would revert back to the old acreage. </li></ul><ul><li>Some districts when relinked acreages would come up as many as three times. </li></ul>
    14. 15. LAYERS <ul><li>Boundary- This is the parcel line work where we actual draw the lines for the Parcels or do COGO work. </li></ul><ul><li>Tax parcels- This is the layer where the parcel polygons reside </li></ul><ul><li>Parcel hooks- land hooks </li></ul>
    15. 16. Wood County Seamless Coverage
    16. 17. AIR SHOTS <ul><li>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. </li></ul>
    17. 19. Air Shot 2003
    18. 20. NEW ORTHOS Coming Soon <ul><li>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. </li></ul><ul><li>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. </li></ul><ul><li>The 2003 photos are 36 inch pixels. </li></ul><ul><li>Assessors can contact their local Sheriffs department for availability. </li></ul>
    19. 21. Mapbook Layer <ul><li>We also use the DS Mapbook which allows us to print all new tax maps and to customize the field maps instead of just running copies of the drawer maps for the field workers. </li></ul><ul><li>We can also quickly turn all of these maps into JPEGs, PDFs, BITMAPS, or other file types. They then can be printed on letter size maps, E-mailed, or sent to the state. </li></ul>
    20. 22. Mapbook Grid
    21. 23. Field maps <ul><li>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. </li></ul>
    22. 24. Field map
    23. 25. Field Use <ul><li>At some point we would like to try using the system on laptops in the field which some counties are doing. </li></ul>
    24. 26. <ul><li>Construction- You can use this layer when drawing new parcel lines then copy key </li></ul><ul><li>them to the boundary layer. </li></ul><ul><li>District Lines- for district line and Corporation lines </li></ul><ul><li>Flood & Contours- This layer contains the Fema flood maps and twenty foot contour lines. </li></ul>
    25. 27. FLOOD PLAIN DATA <ul><li>Turn on the flood plain layer </li></ul><ul><li>Blue line indicates the extent of the 100 year and the 500 year flood plains </li></ul><ul><li>Click over the subject property </li></ul><ul><li>Identify box tells flood plain zone and the firm panel map number </li></ul>
    26. 28. FLOOD ZONE INFO
    27. 29. FLOOD ZONE
    28. 30. Fema map
    30. 33. Contour lines <ul><li>Contour lines displayed with elevation on lines. </li></ul>
    31. 34. contours
    32. 35. Adding Layers <ul><li>WVU has a GIS clearing house were they store GIS maps of all sorts which we can log on and down load layers into our GIS for FREE. </li></ul><ul><li>Contours </li></ul><ul><li>District Lines </li></ul><ul><li>Orthophotos </li></ul><ul><li>Streams & Rivers </li></ul><ul><li>Topo Maps </li></ul>
    33. 36. WV GIS TECHNICAL CENTER <ul><li>http://wvgis.wvu.edu/ </li></ul>
    34. 39. <ul><li>911 layer- There are numerous layers in our 911 maps primarily we use the Streets, roads names, and address layers in our maps The 911’s full project is out on the internet. </li></ul><ul><li>Incorporating this layer into our GIS helps with correlating address with parcel IDs </li></ul><ul><li>http://www.woodcounty911.com </li></ul>
    35. 40. 911 Map
    36. 41. Neighborhood Delineation Maps <ul><li>We also have neighborhood delineation maps that are printed out of the system. The field people can use these to determine if they have any parcels in the wrong neighborhood. </li></ul><ul><li>You can corrected parcels in the wrong neighborhood eliminated neighborhoods and created neighborhoods utilizing this information. </li></ul>
    37. 43. FIND <ul><li>To find a parcel on the map click on the find box and type in the map number. </li></ul><ul><li>We have over 900 hundred maps in Wood County with GIS I can be on any map in the county in 30 seconds or less. </li></ul>
    38. 44. Find A Tax map
    39. 45. FIND <ul><li>Click ok then type in the parcel number. </li></ul>
    40. 46. FIND THE PARCEL
    41. 47. Find result
    42. 48. Mall <ul><li>Information displays with a click of the mouse on the parcel of interest. </li></ul><ul><li>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. </li></ul>
    43. 49. Grand Central Mall GRAND CENTRAL MALL
    44. 55. GIS in West Virginia <ul><li>based on the 2007 roll call information. There were about 33 WV Counties working towards a GIS </li></ul>
    45. 56. Wood County Website <ul><li>http://www.woodcountywv.com </li></ul><ul><li>Most record searching can be done online </li></ul><ul><li>Scanned tax maps, newer deeds, IAS info, home sketch. </li></ul><ul><li>Wood County’s GIS has been on the internet since October 2008. </li></ul>
    46. 57. Querry <ul><li>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. </li></ul>
    47. 58. Attributes Table (IAS Database)
    48. 59. 1 to 5 Ac
    49. 60. Querry <ul><li>. 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. </li></ul>
    50. 61. Clean up your data <ul><li>You can do queries to clean up your data. You can search the attributes table sort ascending on the acreage field all null acreage will come to the top then search then out and find out why. </li></ul>
    51. 62. Attributes Table <ul><li>You can search the attributes table sort ascending on the parcel ID field all parcels with no ID will come to the top then search then and find out why they have no ID. </li></ul>
    52. 63. No parcel ID
    53. 64. Check tax exempt parcel <ul><li>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. </li></ul>
    54. 65. Mismatch maps to IAS <ul><li>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. </li></ul>
    55. 66. Internet use by pros <ul><li>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 </li></ul><ul><li>Companies, and the general public. </li></ul>
    56. 67. Internet convenience <ul><li>. 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. </li></ul>
    57. 68. Internet saves time <ul><li>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. </li></ul>
