INDIANA NHD MAINTENANCE

WHAT DO WE NEED TO DO?ROBERT N WILKINSON

INDIANA DNR

DIVISION OF WATER

CURRENT NHD INDIANA FLOWLINES

IN 2016, INDIANA FINISHED A PROJECT UPDATING ITS SURFACE WATERS DATA IN THE NHD TO LOCAL-RESOLUTION. INDIANA USED HIGH-RESOLUTION IMAGERY AND ELEVATION DATA TO CREATE A MORE ACCURATE DEPICTION OF SURFACE WATERS AS COMPARED TO WHAT PREVIOUSLY EXISTED IN THE NHD (E.G. PREVIOUS HYDROGRAPHY WAS FROM 50+ YEAR-OLD MAPS AT A SCALE OF 1”=2000’, WITH THE NEW HYDROGRAPHY MAPPING AT A SCALE OF 1”=200’ (10 TIMES MORE-ACCURATE AND MORE-DETAILED THAN PREVIOUS).

WHILE THE RESULTS ARE A GREAT IMPROVEMENT, THERE WERE SOME ERRORS WHEN DRAWING THE DATA AND THE DESCRIPTIVE INFORMATION FOR THESE FEATURES. NOW, WE ARE SEEKING YOUR INPUT TO HELP CORRECT THE DATA TO MAKE THEM EVEN MORE VALUABLE.

CURRENT EFFORT – RN WILKINSON

• HUC 05120110 – SUGAR

• HOURS DEVOTED OVER THREE MONTHS – 187

• OVER 60K EDITS

• MAYBE ONE HALF OF HUC COMPLETED

• FCODE ATTRIBUTES NOT POPULATED

• LINEWORK CORRECTIONS

• WATERBODY CORRECTIONS

• GNIS NAME CORRECTIONS/ADDITIONS

• MAJORITY OF TIME SPENT POPULATING FCODES

• GUESS – 150 HRS

• I WILL NOT BE ABLE TO DEVOTE THIS MUCH TIME TO THIS PROJECT GOING FORWARD

• DAVE NAIL’S EMAIL – FUNDING????

• CAN WE LEVERAGE OUR NEED FOR CONTRACT MONEY?

• HOW?

All, The USGS National Map liaison section is hoping that in the near future there will be some USGS NHD/WBD funding.If funding does become available, maybe by next year, it will probably be announced publicly, be a competitive process and probably require some percentage of cost-share (similar to our 3DEP Elevation program). I know you already have a WBD project starting, but do you have any additional candidate projects and if so could you let me what they are? We're canvassing NHD/WBD stewards to see what types of projects they have in mind.

Thank you,Dave

CHANGE TO OUR NHD MAINTENANCE WORKFLOW

• ENTER INTO AGREEMENT OF CO-EDIT WITH USGS

• SIMPLE PHONE CONVERSATION WITH USGS REPRESENTATIVE (JOEL SKALET)

• COORDINATION THROUGH HIS OFFICE AND USING WEBSITES

• STATE DATA STEWARDS WILL CONCENTRATE ON MARKUP APP ISSUES• USING PROVIDED TOOLS, VALIDATE SUBMISSIONS AND MAKE EDITS

• TIME RESTRAINTS PREVENT DOING THE ORIGINAL PLANNED EDITS

• ORIGINALLY WE WOULD MAKE ALL EDITS FOR THE STATE

• WORKFLOW CALLED FOR US TO SCRUB THE TOPOLOGY AND ATTRIBUTES FOR ERRORS AND CORRECT AS WE FOUND ERRORS

• STATE WILL CONCENTRATE ON MAKING CORRECTIONS TO VALIDATED ISSUES

• OTHER OBVIOUS ISSUES CAN BE CORRECTED AT THE TIME.

• STATE NEEDS TO CONSIDER CONTRACTING HELP FOR THE MAINTENANCE PROJECT

• LINEWORK UPDATE FROM PROJECT IS MASSIVE

• ATTRIBUTE DATA WAS NOT POPULATED DURING CONFLATION

• NEW ‘FCODE’; “DRAINAGEWAY” FEATURE ADOPTED BY USGS WILL NEED TO BE APPLIED TO LINEWORK!

• REASONING BEHIND NOT UPDATING THE ‘FCODE’ ATTRIBUTE…

DESCRIPTION OF DRAINAGEWAY:STILL GATHERING INFORMATION AND GETTING A GRASP ON THIS!

• HERE'S THE DESCRIPTION OF DRAINAGEWAY: A DRAINAGEWAY IS DEFINED AS A WATERCOURSE THAT CONVEYS, OR IS LIKELY TO CONVEY WATER BUT LACKS A CLEARLY DEFINED CHANNEL OR BANKS DIFFERENTIATING IT FROM AN EPHEMERAL STREAM/RIVER. DRAINAGEWAYS TYPICALLY CONVEY WATER FOR LIMITED PERIODS OF TIME AND DO NOT CARRY PERENNIAL FLOW EXCEPT WHEN FLOW IS THE RESULT OF CONTRIBUTIONS FROM CONSTRUCTED SUBSURFACE OR OTHER HUMAN-INDUCED DRAINAGE (E.G., FOUNDATION DRAINS, OR STORM DRAINS THAT INTERCEPT GROUNDWATER). DRAINAGEWAYS MAY FOLLOW NATURAL TOPOGRAPHIC FLOW PATHS OR CONSTRUCTED OR HUMAN-MADE FLOW PATHS.

• LINEAR HYDROGRAPHY FEATURES IN THE NHD ARE, AND ARE INTENDED TO BE, INITIALLY DERIVED FROM ELEVATION SURFACES (IN PARTICULAR THE HIGH QUALITY 3DEP DATASETS). ONCE DERIVED FROM ELEVATION SURFACES, THE LINEAR HYDROGRAPHY FEATURES ARE VERIFIED BY COMPARISON TO OTHER EXISTING HYDROGRAPHY DATASETS (VIA CONFLATION), FIELD VERIFICATION, AND/OR REMOTE SENSING IMAGERY. THE VERIFICATION PROCESS MAY INCLUDE CONSIDERING WHETHER A FLOWLINE CARRIES WATER PERENNIALLY (YEAR-ROUND FLOW), INTERMITTENTLY (FLOW CEASES FOR WEEKS OR MONTHS EACH YEAR) OR EPHEMERALLY (FLOWING FOR HOURS OR DAYS FOLLOWING A PRECIPITATION EVENT).

•

• THEREFORE, A NEED FOR A FEATURE TYPE/FEATURE CODE OF “DRAINAGEWAY” HAS BEEN RECOGNIZED.

• THIS FCODE ‘46800’ WOULD SERVE TO IDENTIFY HYDROGRAPHIC FEATURES EXTRACTED FROM ELEVATION DATA THAT EITHER HAVE NOT YET BEEN VERIFIED AS FEATURES THAT SHOULD BE CLASSIFIED AS STREAM/RIVER OR AS FEATURES THAT AREN’T STREAMS BUT HAVE THE POTENTIAL TO CONVEY WATER. THIS DISTINCTION WILL BECOME INCREASINGLY IMPORTANT AS NEW, HIGHER DENSITY NHD DATA IS DERIVED FROM HIGH RESOLUTION ELEVATION SOURCES. INCLUSION OF THIS NEW FCODE WILL IMPROVE THE DATA QUALITY OF EXISTING FLOW LINES AND ENSURING THAT NEWLY CREATED ‘DRAINAGEWAYS’ ARE EASILY CLASSIFIED AND VERIFIED.

• PARTNERS CURRENTLY ENTER SUCH FEATURES INTO THE DATABASE USING FCODE ‘46000’ (STREAM/RIVER), BUT THIS IS NOT AN ACCURATE DESCRIPTION OF THESE FEATURES. DRAINAGEWAY IS A MORE ACCURATE DESCRIPTION OF THIS TYPE OF FEATURE.

HOW CAN YOU HELP?

WE NEED LOCALS TO SUBMIT SUGGESTIONS FOR EDITS TO NHD VIA THE MARKUP TOOL

PROVIDED BY USGS.

WE HAVE CREATED A WEBSITE THAT WILL GIVE BACK STORY AND EXPLANATION FOR THIS

PROJECT. IT ALSO HAS A LOT OF INFORMATION ON THE MARKUP TOOL AS

WELL AS LINKS TO THE MARKUP TOOL AND ITS HELP TOOLS.

REQUIREMENTS:

• GOOGLE ACCOUNT OR AGOL ACCOUNT

• USES GOOGLE CHROME ONLY

• FILL IN AS MUCH INFORMATION AS YOU CAN IN COMMENTS TO SUPPORT

SUGGESTION

• FOR ‘REVIEW/VALIDATION’ PHASE

• YOUR INPUT IS DESIRED, BUT WE NEED YOU TO EXPLAIN WHY WE ARE CHANGING SOMETHING!

• VALUABLE LINKS TO TRAINING VIDEOS ON THE MARKUP TOOL!

• POLYGON – SUGGEST NEW WATERBODY OR HIGHLIGHT AN ENTIRE AREA WHERE ISSUES OCCUR

• COMMENT ONLY/ATTRIBUTE CHANGES

• HELP MENU IS USER FRIENDLY AND RECOMMENDED TO DISCOVER THE MYRIAD OF OPTIONS THIS TOOL HAS, PLUS I FOUND THE

MARKUP LIFE CYCLEREVIEW AND VALIDATE –

USGS AND INDIANA STEWARD

PERFORM EDITS –

WE HAVE THREE OPTIONS IN PARTNERSHIP WITH USGS:

• USGS WILL DO ALL EDITS FOR VALIDATED ISSUES

• EDITS WILL BE PERFORMED BY USGS PERSONNEL.

• ON THEIR TIME LINE ON FIRST COME FIRST SERVED BASIS.

• INDIANA WILL ASSUME RESPONSIBILITIES TO DO ALL EDITS ON VALIDATED ISSUES

• INDIANA ASSUMES ALL RESPONSIBILITIES FOR MAINTENANCE.

• NOT ENOUGH TIME IN THE WORK SCHEDULE FOR ALL THAT NEEDS DONE.

• *A PARTNERSHIP IS CREATED WHERE BOTH PARTIES DO WHAT THEY CAN WHEN THEY CAN.

• NHD MAINTENANCE PERFORMED BY BOTH.

• COORDINATION IS KEY!

• EVEN WHEN A HUC HAS BEEN CHECKED OUT BY POC, USGS CAN MAKE EDITS WITHIN THE HUC.

• ALLOWS FOR CRITICAL EDITS TO BE MADE FASTER.

MARKUP REVIEWER • REVIEWER SOFTWARE IS AN ADD-IN TOOL IN ARCMAP.

• ONLY TRAINED AND CERTIFIED PERSONNEL HAVE ACCESS TO THIS TOOL!

• TRAINING THROUGH USGS

• CERTIFIED BY USGS AND GIO OFFICE - STATE DATA STEWARD

• STATE STEWARDS REVIEW SUBMISSIONS:

• NOTIFICATION AT BEGINNING OF MONTH FOR ANY SUBMISSIONS FOR THE STATE.

• RESPONSIBLE FOR TIMELY REVIEW

• DETERMINATION TO PROCEED:

• IN PROGRESS

• WON’T FIX

• STATE STEWARD EDITS:

• PRIORITIES FOR EDITS WILL BE DETERMINED FROM MARKUPS

• IF HUC INVOLVED IS CHECKED OUT BY STEWARD, THEN EDITS CAN BE MADE

• HANDSHAKE AGREEMENT WITH USGS TO HANDLE AS PARTNERS
