NOT DISCUSSED TODAY DUE TO TIME LIMITS:
• TAXING DISTRICTS – MUNICS, SCHOOLS, TIF, ETC…
• ELECTION DISTRICTS – MUNICS, SCHOOLS,
LEGISLATIVE, COMMISSIONER, ETC…
• OTHER DISTRICTS - ZIP
UPDATE RECEIPT PROCESS
PLATS – LICENSED LAND SURVEYOR FOR CHECKING
PLATS – ANYONE RELATED TO THE PLAT COULD BE FILING
LOT SPLITS/COMBOS – COME FROM PROPERTY OWNERS
ROAD NAME/TURNBACKS – FROM JURISDICTION
CENTERLINES – ADDED FROM NEW PLATS OR ROAD
OPENINGS. ADDRESSES ARE ADDED FROM VARIOUS
RESOURCES (USUALLY TAX ATTRIBUTES FROM PARCELS
OR SHERIFF’S INFORMATION).
 POINTS – ADDED FROM NEW PARCELS ALONG WITH
ASSOCIATED ATTRIBUTION FOR CURRENT AND PENDING
TAX INFORMATION FROM AUDITOR’S PINS DATABASE
 TAXING DISTRICTS – DOCUMENTS FILED WITH AUDITOR
AND DISTRIBUTED TO SURVEY TO EDIT CURRENT
DISTRICTS
 ELECTION DISTRICTS – DOCUMENTS FILED WITH STATE
AND AUDITOR, DISTRIBUTED TO SURVEY TO EDIT. USUALLY
DONE DURING REDISTRICTING, BUT COULD BE AFFECTED
BY TAX DISTRICT CHANGE (ANNEXATION)

PARCELS
• PLATS
• LOT SPLITS / COMBINATIONS
• ROAD OPENINGS / VACATIONS/TAKINGS
• STREET CENTERLINE
• STREET NAMING CHANGES
• ATTRIBUTE CHANGES (ATB, PRECINCT CODE, PINS)
• COSMETIC CHANGES (ADJUSTING TEXT TO NEW COGO LINES)
• COGO LINEWORK CHANGES
PLATS
 CIC’S – NO MUNICIPAL REVIEW
 RLS – MUNICIPAL REVIEW
 SUBDIVISION – MUNICIPAL REVIEW
• PLATS ARE SUBMITTED BY LICENSED LAND SURVEYOR FOR
CHECKING AND APPROVAL BEFORE FILING, ALSO CITIES MAY BE
SEEING A PRELIMINARY PLAT PRIOR OR AT THE SAME TIME WE ARE
CHECKING.
• PLATS CAN STAY IN OUR DRAWER FOR UP TO 2 YEARS (PURGED
AFTER 2 YEARS) BEFORE THE DEVELOPER DECIDES TO FILE OR IS
FILEABLE.
• PLATS THAT ARE SIGNED BY THE MUNICIPALITY MAY, FOR SOME
REASON, NOT GET APPROVED BY COUNTY(USUALLY TORRENS PLATS)
• WE DO NOT ADD PLAT DATA TO MAP UNTIL PID’S ARE ASSIGNED BY
AUDITOR OFFICE TO ENSURE NO NULL POLYGONS.
PLATS (cont’d)
•
PLAT DATA SUBMITTED AS POINT FILES TO SURVEYOR’S OFFICE
1.
CHECKED WITH COORDINATE GEOMETRY SOFTWARE
THAT ASSIGNS UNIQUES LEVELS TO NEW LINEWORK
2.
NEW LINEWORK (DWG) IS IMPORTED, GEOMETRY AND
ATTRIBUTION IS PROCESSED USING SEVERAL CUSTOM
(ESRI) GEOPROCESSING MODELS (Figure 1)
3.
LINEWORK IS IMPORTED INTO THEIR RESPECTIVE
FEATURE CLASSES IN SDE
4.
POLYGONS ARE CREATED FROM LINEWORK AND
IMPORTED INTO SDE
5.
LOT DIMENSION ANNOTATION CREATION IS AUTOMATED,
MANUAL COSMETIC FIXES ENSUE
•
TURNAROUND IS USUALLY IS ABOUT 2-4 WEEKS FROM FILING,
DEPENDING ON THE WORK LOAD
•
PLATS HAVE THE HIGHEST PRIORITY TO COMPLETE DUE TO
BANG-FOR-THE-BUCK.
PLATS (cont’d)
Figure 1. Custom Geoprocessing Model Examples
LOT SPLITS / COMBINATIONS
•
SPLITS OR COMBINATIONS ARE SUBMITTED BY THE PROPERTY
OWNER EITHER AS A DEED, PLAT (TO RECORDER) OR LETTER OF
REQUEST(TO AUDITOR). THE AUDITOR WILL NOT ACCEPT THESE
CHANGES WITHOUT CITY APPROVAL OR IN THE CASE OF A
LENGTHY LEGAL DESCRIPTION , UNLESS PROVIDED BY A
LICENSED LAND SURVEYOR.
•
AUDITOR SUPPLIES DESCRIPTION AND PIDS TO SURVEYORS.
•
SURVEYORS GET SPLIT / COMBINATION DESCRIPTION AND MAKE
CHANGES TO EXISTING PARCELS.
•
OLD PARCEL(S) GETS A FEATURE CLASS CHANGE TO PARCELDIV
THAT DO NOT SHOW UP ON THE METROGIS EXTRACT, BUT DO
SHOW ON THE FILE GEODATABASE.
ROAD VACATIONS / TAKINGS
•
PUBLIC ROAD AND ALLEY VACATIONS ARE INITIATED BY THE
AUTHORITY THAT HAS JURISDICTION OVER THAT RIGHT-OF-WAY
PASSED ON TO RECORDER AND/OR AUDITOR BY CITY COUNCIL
RESOLUTION. THESE RESOLUTIONS ARE PASSED ON TO
SURVEYORS OFFICE FOR CHANGES TO MAP DATA.
•
SURVEYORS TRY TO ADD THESE AS SOON AS POSSIBLE ALONG
WITH DOCUMENT NUMBERS, BUT THEY HAVE LOWER PRIORITY
THAN PLATS OR SPLITS/COMBOS, UNLESS THEY ADD PROPERTY
TO ADJACENT PROPERTIES. IF ENTIRE PARCEL IS TAKEN BY A
DOCUMENT(S), THE PID MAY REMAIN AS A PID_IN_RTWY AND MAY
REMAIN CURRENT, BUT NO POLYGON IS CREATED OR LEFT
BEHIND.
•
SURVEYORS GET RESOLUTIONS FROM AUDITOR AND PLACE
THEM IN TO-DO BY DATE RECEIVED.
STREET CENTERLINE
• PUBLIC ROAD OPENINGS FROM NEW PLATS ARE ADDED AS
SOON AS POSSIBLE, AS THESE HAVE ADDED-VALUE FOR
GEOLOCATION END-USERS (IE. SHERIFF, GIS, CITIES,
ETC…)
• ANY OTHER DOCUMENT OR INPUT THAT WOULD IDENTIFY
OPENINGS OR CLOSURES ARE COMPLETED ON THE
CENTERLINE IN A TIMELY FASHION.
STREET NAME CHANGES
•
PUBLIC ROADS ARE DEPENDENT ON THEIR RESPECTIVE
JURISDICTION TO NAME THEM AND KEEP US INFORMED OF ANY
UPDATES.
•
PRIVATE STREETS ARE HARDER TO IDENTIFY - WE GLEAN
INFORMATION FROM THE PLATS AND ORTHOPHOTOS.
•
ROAD TURNBACKS FROM GOVERNMENT ENTITIES TO OTHER
GOVERNMENT ENTITIES, QUESTIONS THE RENAMING OF THESE
ROADS IN A TIMELY BASIS. I DO NOT HAVE A GOOD ANSWER FOR
ALL TURNBACKS AS TO THE NOTIFICATION OF CHANGE. IT
WOULD BE A GOOD IDEA IF THE CITIES RECEIVE OR TURNOVER
ROADS TO ANOTHER ENTITY, THEY INFORM SURVEY OFFICE
DIRECTLY.
•
THESE CHANGES USUALLY HAVE AN EASY FIX AND ARE DONE
QUICKLY.
ATTRIBUTE CHANGES
•
WE GET A MONTHLY CUT OF TAX INFORMATION (1ST OF THE
MONTH) FROM OUR MAINFRAME – THE TABLE IS JOINED TO THE
PARCELS FOR METROGIS POINT & POLYGON EXTRACTS (WHICH
ARE RUN MONTHLY, BUT DISTRIBUTED QUARTERLY).
•
FEBRUARY 15TH IS THE APPROXIMATE DATE HENNEPIN TURNS
TAX DATA OVER TO THE NEW TAX YEAR.
NEWLY CREATED PIDS IN THE CURRENT TAX YEAR WILL BE
CURRENT THE FOLLOWING TAX YEAR. THEY MAY SHOW UP AS
“DIVISION-IN-PROCESS” OR “PENDING”. THAT IS WHY WE KEEP
THE UNDERLYING POLYGON AS A PARCEL_DIVIDED (BECAUSE
THEY ARE STILL CURRENT)
•
•
IN THE FILE GEODATABASE, SUBSTANTIAL ATTRIBUTION IS
ATTACHED TO THE POINTS FEATURECLASS. THE POLYGONS ARE
LIMITED TO ATB AND PRECINCT-CODE; THESE ATTRIBUTES ARE
MAINTAINED BY THE SURVEY DIVISION AND NOT EXTRACTED
FROM THE MAINFRAME.
COSMETIC TEXT CHANGES
• COSMETIC TEXT CHANGES ARE USALLY DUE TO THE
SHIFTING OF LINEWORK DUE TO COGO83 PROJECT.
• THE COGO83 PROJECT TEAM RESEARCHES DEEDS AND
IMPORTS RECTIFIED LINEWORK AND POLYGONS TO OUR
SDE DATABASE.
• SOME LINEWORK MAY SHIFT SIGNIFICANTLY TO REQUIRE
COSMETIC CHANGES TO ANNOTATION (TEXT) TO BE
COMPLETED. (SEE COGO COMPLETION MAP)
COGO83 PROJECT
•
THE COGO83 PROJECT TEAM IS REDIGITIZING PARCEL LINES
FROM RESEARCHED DEED DESCRIPTIONS, RECORDED PLATS,
AND OTHER DOCUMENTS PERTINENT TO IDENTIFYING TAXABLE
PROPERTIES.
•
THIS IS A LONG-TERM PROJECT STARTED IN ABOUT 2004… THE
ESTIMATED YEAR OF COMPLETION IS 2012.
•
BE AWARE THAT THE PROPERTY LINES IN YOUR CITY MAY MOVE.
•
PROPERTIES NEAR WATER ARE MORE LIKELY TO MOVE DUE TO
THIS PROCESS. THE PROPERTY LINES WILL MATCH MUCH
BETTER TO THE AERIAL PHOTOS ONCE COMPLETED.
•
THIS PROJECT IS NOT A SURVEY, THEREFORE THE LINES SHOULD
NOT BE USED TO SURVEY FROM.
DATA FORMATS
AERIAL PHOTOGRAPHY:
• DISTRIBUTED IN MRSID
• TIFF IS LIMITED TO ‘REQUEST ONLY’ DUE TO SIZE OF FILES.
• SECTION TILES ARE STANDARD, BUT CAN ENVELOP A
SMALLER AREA FOR SMALL LIMITED PUBLIC REQUESTS.
• 2009 AERIAL REQUEST FOR BIDS WILL BE GOING OUT
SOON.
• HENNEPIN COUNTY IS REQUESTING TO HAVE A DECEMBER
31, 2009 DELIVERY DATE IN THE BID.
DATA FORMATS
PARCELS – SHAPEFILE:
•
COUNTY-WIDE PARCEL SHAPEFILE EXTRACT FOR
METROGIS
•
WE HAVE A PROCESS THAT CAN EXTRACT BY INDIVIDUAL
OR MULTIPLE MUNICIPALITIES
1. CUSTOM OFFSETS ARE ACCOMODATED
2. IDENTICAL ATTRIBUTES TO THOSE OF METROGIS
EXTRACT
DATA FORMATS
PARCELS – FILE GEODATABASE:
•
LOOK AND FEEL OF OUR SDE DATA MODEL
•
THE COMPLETE TAX INFORMATION TABLE IS OMITTED IN
THE EXTRACTED GDB
•
LIMITED ATTRIBUTES ARE ATTACHED TO THE POINTS FILE
1. CAN BE JOINED TO THE PARCEL_BASE POLYGONS
2. IDENTICAL ATTRIBUTES TO THOSE OF METROGIS
EXTRACT
DATA FORMATS
DISTRICTS:
• INDIVIDUAL LINE, POINT, OR POLYGON FEATURES CAN BE
REQUESTED IN A SHAPEFILE FORMAT WITH FEATUREASSOCIATED ATTRIBUTION
• MOST OF THESE EXIST IN THE DISTRIBUTED FILE
GEODATABASE
DATA DISTRIBUTION
MEDIA / METHODS:
• CD (700MB)
• DVD (4.7GB)
• FTP
1. CURRENTLY HAVING TROUBLE WITH INTERNET
EXPLORER 7.X SENDING DATA TO FTP SITES
DATA DISTRIBUTION
LICENSING:
•
CURRENT LICENSE AGREEMENTS MUST BE IN PLACE
WITH THE ENTITIES AND THEIR CONSULTANTS
1. FOR USE BY A CONSULTANT
2. FOR DISTRIBUTION TO A CONSULTANT
•
MOST MUNICIPALITIES ARE CURRENTLY LICENSED AND
UNDER THE EXTENSION AGREEMENTS.
DATA DISTRIBUTION
LOOKING FORWARD…..
• DISCUSSION TO REVIVE HENNEPIN COUNTY FTP SITE
• STUDIES ON OTHER DISTRIBUTION METHODS
• HENNEPIN COUNTY IS WORKING ON A NEW
FORMAT/PROCESS FOR LICENSING IN THE FUTURE
