Improved IHS STARS Data SystemImproved IHS STARS Data System

Using ESRI ArcView/ArcReader on the

NavajoDSFC DE-OM Meeting

April 2012

Where in the world is that waterline, anyway?

The NTUA contracted the GIS mapping of all of the water utilities on the Navajo Reservation, including waterline, tanks, wells, valves, etc. The IHS has been using that valuable data for hydraulic modeling and other important project-related tasks.

ArcView as a Planning and Design Tool

• Locating nearest existing or planned waterline• Identifying nearby homes• Avoiding right-of-way obstacles• Locating other existing utilities• Storing data on existing surveying control

points• ArcPad on a mobile device allows all this to be

done in the field

Homeowner submits application - site visit completed and GPS reading entered into ArcView

Topo Map from ESRI online support superimposed with aerial image to view home and section lines

Land Status layer helps determine that home is in Allotment # 1880

Zoomed out view shows home in relation to the existing (green) waterline and close to SDS waterline SDS-NM17448-0104

Home added to SDS Project in Attribute Table

Maps and namelists can be easily be printed to submit for SDS

ArcView as an Operation and Maintenance Tool

• One centralized source for all as-built data that can be easily transmitted and shared

• Hyperlinks allow storage of project as-builts with pertinent design data

• Changes in project status automatically displayed based on changes to attribute values

• ArcPad on a mobile device allows operators/engineers/technicians to access data on any facility while at the site

View Home Details using Hyperlink

View Waterline Profiles using Hyperlink

View Well Details using Hyperlink

ArcView provides:

• An electronic, georeferenced “base map” alternative to cumbersome mylar and paper copies of as-builts

• A forum to integrate the Tribe’s GIS data with our hydraulic models and survey data

• A tool to determine the easiest way to extend services to a home by identifying the nearest existing, funded (PDS) or proposed (SDS) waterline

• Coordinate information, based on any system, for waterline tapping or other permits

• A way to store and geographically organize project as-builts
