Statewide Parcel Map Inventory Update
By Jay Krafthefer and Sally Wakefield, MnDOT
The
Statewide Parcel Map Inventory has been updated with new results, and more
units reporting. The state’s two National Forests, 4 tribal governments,
and all 87 counties are part of this year’s survey. The accompanying map
shows status in the counties: 56 counties doing parcel mapping (up from 54
in 2003) and 46 counties more than 75% complete with their work (compared
to 41 in 2003).
Inventory results are available at
http://www.lmic.state.mn.us/chouse/SPMI/Reporting/. These include
maps, reports for each county, and various methodology and summary
reports. Standard maps can be presented, like the one accompanying this
article, or two themes can be mapped together; e.g., development status
and whether the county employs a surveyor. Custom reports can be
generated for any county by clicking on desired items. Maps and reports
are quickly presented on the screen, but can be transformed into print
friendly output.
MnDOT
is supporting these inventories to help its own staff work better with
local government in Minnesota, but the results have proved useful to those
governments too. The 2003 inventory was, conducted by University of
Minnesota and ProWest and Associates, won the 2004 Partnership Award
from the Center for Transportation Studies, an honor reserved for projects
that have proved especially useful to the state.
The 2004 inventory was
conducted by the Land Management Information Center (LMIC) in the
Department of Administration and allowed respondents to update their own
information on the web using a password to protect response integrity.
Some significant changes appear compared to the 2003 inventory, possibly
due to question clarification and evolving respondent understanding of
question meaning. MnDOT hopes to update this inventory on a regular
basis.

Statewide Digital Parcel Map Inventory

Every county would like to have up-to-date parcel maps to assist the assessor, E-911, environmental, and a wide variety of other applications. Having the maps in digital form allows for rapid updating whenever a change takes place. It also facilitates GIS applications like producing letters
addressed to adjacent property owners. Until now, no one had a good idea of how many counties were on this path – or which ones are on track. A recent inventory has changed all that.
The accompanying map of Minnesota tells the story. Nearly 2/3 of Minnesota Counties are creating digital parcel maps – 54 of 86 reporting. In well over half (33 of 54) those counties parcel work is approaching completion; these counties are distributed across the state. Many of the remaining 21
counties are just getting started with their digital parcel mapping. Most of the 32 non-digital counties are small and rural. Detailed Survey Results are available for each county. Maps on that website show summary results for some 22 related questions in the inventory.
Our major goal was to create an inventory of existing digital parcel systems in Minnesota, along with contact information. A secondary goal of the inventory involved identifying the method of parcel data development, the frequency of maintenance, data development standards and distribution
practices, remonumentation efforts, and other key information. All that information is on the website for 86 of the Minnesota counties, seven non-metro cities, and one Indian Reservation.
The inventory was sponsored by the Minnesota Department of Transportation. Its Office of Land Management needs information about land ownership whenever highway construction or maintenance is planned, so knowing current status and contact names is useful to
them. Other state and local government agencies also have a need for such information, so the results are posted on the website for use by everyone. The Minnesota Governor’s Council on Geographic Information has a strong interest in developing parcel mapping statewide and was happy to learn about the level of activity across the state.
The inventory is very current and plans are in place to keep it current. Data was collected from fall 2002 and into early winter 2003. Plans are to update the inventory annually. Ideally, key county staff would be given a password that would allow them make changes directly into an on-line database. The current version on the web is in PDF format and not amenable to this approach. Contact
jay.krafthefer@dot.state.mn.us if you see mistakes in the current version that need to be corrected.

MnDOT Resources to Aid Parcel Mapping
MnDOT has data and map products available that could assist local governments with their parcel work. These resources are scattered across the department, but a new brochure – Survey and Land Information – has been developed providing contacts to relevant MnDOT people and websites. Maps and related documents are in a variety of formats, ranging from paper to scanned
images to CAD files to GIS datasets. They include:
