GIS Programs

GIS Program

The PWSSP has implemented a GIS program and encourages all Navajo Nation community planners to become involve in environmental planning in their community development initiatives. Protection of the community's drinking water source(s) is very important as it will have serious impact on the community. Planning support systems can measure and compare performances of different planning scenarios according to planner- or citizen-defined indicators for land use, transportation, natural resources, and employment, to name a few. As communities grow, concerns over the placement of gas stations, sewer lagoons as opposed to septic tanks, hospitals, mortuaries, industrial buildings all need to be considered.

GIS's mission is to establish a positive working relationship to provide computer generated map of various layers, boundaries and community watering point information on the Navajo Nation. PWSSP will continue to collect spatial data for access and distribution of non-sensitive data to requesting parties.

GIS program is preparing to implement a map module and make it available for chapter planners using Internet Mapping capabilities.

GIS Datasets

GIS program will continue to collect and use geographic datasets for access and distribution of non-sensitive data to requesting parties. Currently, general Navajo Tribal Utility Authority (NTUA) dataset are secured by approval of NTUA for the use of GIS dataset license. Navajo EPA-PWSSP will not display their data outside the office without a written consent of NTUA. However, other GIS dataset have come from Navajo Land Department and is available for the general public.
