Using ESRI ArcView/ArcReader on the
NavajoDSFC DE-OM Meeting
April 2012
![Page 17: FACILITIES/SANITARY SURVEYS AS DESIGN TOOL](https://reader035.fdocuments.us/reader035/viewer/2022081513/5681478c550346895db4bc8b/html5/thumbnails/17.jpg)
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

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

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
