GENERAL
- What is
GIS?
GIS
stands for Geographic Information Systems. The
official definition of GIS is a system of hardware and software used for
storage, retrieval, mapping, and analysis of geographic data.
- Where is
your office located?
We
are located in downtown Painesville, OH in the Lake County Administration
Building at 105 Main Street. The GIS/Tax Map Office is in the lower
level. We are open weekdays from 8:00am to 4:30pm.
GIS DATA
- Where can I
get data and how much does it cost?
We
offer GIS data in a few different formats: digital on CD, paper maps, and
online viewing.
|
-
Digital: CDs can be
purchased from our office for $50.00 each. Data formats
include: ESRI Shapefiles & Coverages, DXF, and MrSID & TIFF
Orthophotography. Data Types include everything from Planimetrics
(Roads, Buildings, 2' Contours, etc . . .) to Cadastral (Parcels,
Subdivisions, etc . . .). Payment must be received before CD
media can be mailed. Please make checks payable to 'Lake
County GIS Department'.
-
Paper: Printed maps can be
obtained in a number of different sizes with varying costs. However, availability of custom maps is dependant upon staff workload.

Online: If you would
prefer to print your own copies from the comfort of your home or
business, visit our LakeNavigator
site where you can search for specific properties or simply explore
the county. We have many types of data available including
planimetrics, cadastral, natural resources, civil, and aerial
photography for the entire county. This online service is provided
for free to anybody with an internet connection. |
- How
accurate and current is the GIS data?
The
answer to this question depends on the type of data you are interested
in. Our planimetric data (bridges, buildings, centerlines, 2'
contours, pavement edges, railroads, streams, lakes, and transmission
towers) were captured from April 2000 orthophotos and meet ASPRS Accuracy
Standards for Class 1 Large-scale Maps. The digital orthophotos have
a spatial accuracy corresponding to 1" = 100'. Parcels are referenced
to the digital orthophotos and follow apparent lines of occupation,
therefore, they are not survey accurate. The parcel layer is
continually being updated and the current date will be included in the
disclaimer for the LakeNavigator site. We are in the process of
adding metadata (data about data) to all our GIS layers which will provide
detailed information about precision and accuracy.
If you have more specific questions about our data you may contact us at
the Lake County GIS Department.
- What
coordinate system or projection is the GIS data in?
Ohio
Stateplane coordinate system, North Zone, North American Datum 1983
(NAD83), US Survey Feet.
TAX
MAP / PARCELS
- What is the
difference between a 'tax map' and a 'plat' and how do these relate to the
GIS parcel layer online?
|
-
Tax Map: Maps that are
updated daily by county employees and show ownership, acreage, and
frontage. They are the property of the County Auditor but are
maintained by County Engineer employees.
-
Plat Map: A plan or map of
a piece of land with actual or proposed features. These are
static maps most often produced by engineering firms that shows lot
dimensions and other detailed information concerning changes to the
land.
-
GIS Parcels: The parcel
layer online is based on the linework from both the tax maps and
plats but is also adjusted to the April 2000 aerial photos.
Information like ownership, date of last transfer, address, and such
comes directly from the County Auditor's database and is linked to
the parcels through the 13-digit parcel number. |
- Where can I
find my parcel number and what does it tell me?
You
can find your parcel ID in a number of places, including.
|
-
On your property Tax Bill (upper left-hand corner)
-
Auditor's Transfer Office (provide them a name or address)
-
Treasurer's Office
-
On the Internet. Go to the Auditor's
Real Property Information site. |
