The Alaska Stand Alone Gas Pipeline (ASAP) Route RTE_ASAP layer depicts the route feature for the Alaska Gasline Development Corporation (AGDC) project area and was developed for the AGDC. GIS data for the project is stored in a geodatabase format and is compiled for distribution in ESRI GIS formats. The AGDC, USGS, and Digital Globe imagery were also used. The data was digitized and prepared in 2009-2011 by the Michael Baker Jr., Inc. Accuracy of this alignment is for preliminary engineering and planning purposes only and is based on mapping on two-foot pixel orthoimagery. Later refinements of this alignment will likely utilize a survey control network developed for the project, thus accuracy will be improved for possible construction planning purposes. |
