  • 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 l.jpg

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)

UPDATE RECEIPT PROCESS

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 l.jpg

CIC’S – NO MUNICIPAL REVIEW

RLS – MUNICIPAL REVIEW

SUBDIVISION – MUNICIPAL REVIEW

PLATS

  • 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 l.jpg

PLATS (cont’d)

  • PLAT DATA SUBMITTED AS POINT FILES TO SURVEYOR’S OFFICE

    • CHECKED WITH COORDINATE GEOMETRY SOFTWARE THAT ASSIGNS UNIQUES LEVELS TO NEW LINEWORK

    • NEW LINEWORK (DWG) IS IMPORTED, GEOMETRY AND ATTRIBUTION IS PROCESSED USING SEVERAL CUSTOM (ESRI) GEOPROCESSING MODELS (Figure 1)

    • LINEWORK IS IMPORTED INTO THEIR RESPECTIVE FEATURE CLASSES IN SDE

    • POLYGONS ARE CREATED FROM LINEWORK AND IMPORTED INTO SDE

    • 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.

    Lot splits combinations l.jpg

    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.

    LOT SPLITS / COMBINATIONS


    Road vacations takings l.jpg

    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.

    ROAD VACATIONS / TAKINGS


    Street centerline l.jpg

    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 CENTERLINE


    Street name changes l.jpg

    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.

    STREET NAME CHANGES


    Attribute changes l.jpg

    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.

    ATTRIBUTE CHANGES


    Cosmetic text changes l.jpg

    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)

    COSMETIC TEXT CHANGES


    Cogo83 project l.jpg

    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.

    COGO83 PROJECT


    Data formats l.jpg

    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


    Data formats18 l.jpg

    PARCELS – SHAPEFILE:

    COUNTY-WIDE PARCEL SHAPEFILE EXTRACT FOR METROGIS

    WE HAVE A PROCESS THAT CAN EXTRACT BY INDIVIDUAL OR MULTIPLE MUNICIPALITIES

    CUSTOM OFFSETS ARE ACCOMODATED

    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

    CAN BE JOINED TO THE PARCEL_BASE POLYGONS

    IDENTICAL ATTRIBUTES TO THOSE OF METROGIS EXTRACT

    DATA FORMATS


    Data formats20 l.jpg

    DISTRICTS:

    INDIVIDUAL LINE, POINT, OR POLYGON FEATURES CAN BE REQUESTED IN A SHAPEFILE FORMAT WITH FEATURE-ASSOCIATED ATTRIBUTION

    MOST OF THESE EXIST IN THE DISTRIBUTED FILE GEODATABASE

    DATA FORMATS


    Data distribution l.jpg

    MEDIA / METHODS:

    CD (700MB)

    DVD (4.7GB)

    FTP

    CURRENTLY HAVING TROUBLE WITH INTERNET EXPLORER 7.X SENDING DATA TO FTP SITES

    DATA DISTRIBUTION


    Data distribution22 l.jpg

    LICENSING:

    CURRENT LICENSE AGREEMENTS MUST BE IN PLACE WITH THE ENTITIES AND THEIR CONSULTANTS

    FOR USE BY A CONSULTANT

    FOR DISTRIBUTION TO A CONSULTANT

    MOST MUNICIPALITIES ARE CURRENTLY LICENSED AND UNDER THE EXTENSION AGREEMENTS.

    DATA DISTRIBUTION

    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

    LOOKING FORWARD…..
