An Integrated Geographic Information System over Railroad Valley, Nye County, Nevada

William H. Aymard, Joseph Lintz, Jr., John J. Perry

Evaluation of hydrocarbon potential at Railroad Valley is a process involving the consolidation of different data sets acquired by multiple technologies. Previous studies have demonstrated correlation between fracture systems and geochemical anomalies with oil-producing fields.

An integrated geographic information system (IGIS) is defined as the merging of spatially referenced data. Specifically, it is the consolidation of remotely sensed data in raster format with the vectorized representations of map features for spatial analysis. An IGIS is used to integrate the following data sets: Landsat thematic mapper, digital topography, digital gravity data, well log data, geochemical data, digital aeromagnetic data, seismic data, digitized geologic maps, and organic geochemical data.

It is necessary to (1) analyze how these spatially referenced data sets interact as factors or variables, which may be extremely complex, and (2) establish the fundamental operations for data processing. First, interpreted information from the individual data sets is derived prior to the merging process. A one-way performed discriminant analysis on the multivariate classes follows.
