Project Goal
The primary purpose of this project was to develop and implement a “spatially-enabled” information architecture and web-based user application that was designed to automate the production of map documents and road inventory reports that are submitted by the Tribes to the BIA on an annual basis as part of the Indian Reservation Roads program. The IRRIS system is being utilized as the primary database repository for the storage, maintenance and management of all roadway related information on the Navajo Reservation. In addition to the office automation capabilities, the IRRIS system also includes a field component that allows Navajo DOT engineering technicians to capture and update relevant roadway information while in the field, including digital photographs, GPS positions and inspection data in real time.Business Problem Solved
The implementation of the IRRIS system substantially improved the quantity and quality of roadway inventory data that was submitted annually to the BIA’s IRR program. The IRR program is set up by the Federal government to distribute funding to the US Tribes on a national basis. The amount of funding that the Tribes receive is based primarily on the number of miles in the federal system. Prior to the implementation of the IRRIS system the Navajo DOT endured a labor intensive and inefficient process of developing the BIA deliverables and thus were not receiving their eligible share of funding. The first submission after the IRRIS implementation resulted in 35% increase in funding for FY 2007. In addition to increasing the quantity if inventory data all map documents and reports have been designed specifically to adhere to the BIA format, thus virtually eliminating the possibility of documents be returned to the tribe because of incorrect formatting or missing information.
Technology Implemented
The core system architecture was built on an InLine high-availability, two-tier server system that was optimized for use with ESRI’s ArcGIS Server Advanced Enterprise edition (version 9.2). The spatial database engine is comprised of ESRI’s ArcSDE and Microsoft SQL server, and utilized an LRS (liner reference system) database structure for the storage of all linear roadway geometry. The IRRIS office system utilizes a combination of Perl, Java Script, and Microsoft C #.net as the development languages and ArcGIS Server for the production of mapping documents and GIS visualization tools. The field system was also written in Perl, Java Script, and Microsoft C #.net, but utilizes ArcIMS as the map visualization engine.
