Resolution NHD Project

Mike Martin,

Indiana Dept. of Natural Resources


Quality Control for Local Resolution NHD

• IGIC’s Waters Workgroup has the task of QC for the new local resolution NHD linework

• The vendor, AECOM, submits linework and other reference data by full or partial subbasin every 3 or 4 weeks

• Workgroup has 10 business days to provide feedback to AECOM


Quality Control for Local Resolution NHD


Quality Control Workflow

1. Vendor, AECOM, provides linework2. Members of workgroup review and

identify items of concern3. Vendor addresses concerns4. Workgroup reviews AECOM

resolution and approves or rejects


QC Without ArcGIS Server

1. Vendor, AECOM, provides linework and reference data file geodatabase of checked-out 24K NHD reference data: 6-acre streams, 6-acre

basins, hillshades file geodatabase of new linework shapefile of source data information

Latest Subbasin: 1.86 GB compressed



1. Vendor, AECOM, provides linework and reference data

2. Members of workgroup review and identify items of concern individuals from different organizations no common network requires ArcGIS Desktop different configurations of Windows,

ArcGIS review is not part of normal job duties—

time is of the essence

— ISSUES




2. Members of workgroup review and identify items of concern local copy of all data for each member or

each network individual shapefile of callouts for each

member each reviewer creates ArcMap document

with linework, reference data, and callouts

each reviewer edits individual callouts shapefile

all shapefiles of callouts merged, sent to AECOM

— WORKFLOW




2. Members of workgroup review and identify items of concern

3. Vendor addresses concerns edits the callouts shapefile sends shapefile back to workgroup




2. Members of WWG review and identify items of concern

3. Vendor addresses concerns4. Workgroup reviews AECOM resolution

and approves or rejects shapefile distributed to each reviewer each reviewer adds revised shapefile to

map and review

Advantages Using ArcGIS Server

• No software needed by reviewers• Single copy of all datasets• No prep-work for reviewers• Reviews can be made from any

Windows computer with access to Internet

• Quicker turnaround


QC Review Using Web Application



Map layers of old and new features, reference data



Back-ground layers matching sources used by vendor



Reviewer adds callout at location of found issue



Callout added to enterprise geodatabase



Post QC reviewers check updated lineworkand AECOM’s responses
