SWQDC

Storm Water Quality Data Conversion (SWQDC)

· Multi-year effort led by CCH HOLIS to improve the coverage, accuracy, and dissemination of CCH storm water-related GIS data

· National Pollutant Discharge Elimination System (NPDES) permit · CCH ENV, DPP/HOLIS, DDC, and DFM · Identify and collect potential data sources · Design and populate new storm water geodatabase · Design and build Geometric Network · Design and develop web-based mapping application · Establish long-term maintenance procedures

Geodatabase

Storm Water Geodatabase · Data sources · ~8,000 1995-2006 as-built plans

· ~15 other types, ranging from historical hand-drawn drainage maps to field data collection

· Georeferencing · Heads-up digitizing · Sewing together patch-work file geodatabases · Large QA/QC effort: spatial and attribute data accuracy · Feature counts: · ~65,000 structures · ~62,000 conduits = 1,040 miles · Production of a complimentary project plans database · Almost 70,000 plan records

Geometric Network

Storm Water Geometric Network · ArcGIS Geometric Network · Declaration of Sources and Sinks · Simple Edges · Stand alone, heavy topology; goal: no Orphan Junctions · Overall goal: determinate flow in all conduits island-wide · Integration of State DOT and NAVFAC storm water datasets · Differences in State DOT geometric network design · Overlap between State DOT and CCH data · Modeling the real world and creation of "virtual" network feature classes

Tools

SWAPP Functionality · Basic map navigation and zoom-to · NPDES-specific · Jurisdiction · Spill response · Catch Basin inspections · Report Generator · Geometric Network · Tracing · Flow direction · Project plans · Accessing scanned plan PDFs · Adding georeferenced TIFFs to the map · Parcel data includes external links to CCH Real Property and hi.central.com

An Example

A Recent User Case · ENV notified of a spill plume in Kakaako/Kewalo Basin outfall · ENV request to HOLIS to trace upstream from outfall to identify potential spill sources · Map production with upstream trace and georeferenced construction plans

Technical Architecture

Under the SWAPP's Hood · Custom ArcGIS Server (v10.0) Web ADF design · Local Web ADF-to-ArcGIS Server connection · ArcSDE GIS data repository · SQL Server non-spatial business data repository · Programmed in ASP.NET/VB.NET · Leverages AJAX Partial Post-back lifecycle model · Custom ArcObjects modules · JavaScripted dynamic HTML in user interface · Conserve screen real estate · Avoid pop-up windows · XML configuration file

Deployment

Rolling Out the SWAPP · Multiple demonstrations during and after development · Pre-deployment host scenario definition · Initial deployment in March and April 2011 · Post-deployment testing · First "Service Pack" applied September 2011 · Storm Water GIS on ArcGIS Online in Fall of 2011 · New Report Generator tool scheduled deployment Spring 2012

Lessons

Lessons Learned · Reinforcement of the user-first strategy · Identification of data sources · Importance of field-based feedback, notification, and recognition · Strong feature identification protocol · Web ADF deprecation

Improvements

Improving the SWAPP in the Future · Further integration of NPDES business data · NPDES data clearninghouse · NPDES report generation · Opening to CCH NPDES contractors · Update functionality, especially field-based corrections · Resolve Web ADF dependence
