Open-File Report 99-404
This CD-ROM contains digital data, image files, and text files describing the data formats and survey procedures for aeromagnetic data collected during three airborne geophysical surveys in New Mexico during 1997-1998. The Sandoval-Santa Fe survey covers the southern Española Basin and northern Albuquerque basins, including Española, the western part of Santa Fe, major portions or all of the lands of the Pueblos of San Juan, Santa Clara, San Ildefonso, Pojoaque, Nambe, Tesuque, Santo Domingo, San Felipe, Santa Ana, and Zia, and minor portions of the lands of the Pueblos of Cochiti and Jemez. The Belen survey covers the southern Albuquerque basin from just north of Belen to Bernardo on the south. The Cochiti survey primarily covers Cochiti Pueblo lands, west of Santa Fe. Sander Geophysics, Ltd. conducted the Sandoval-Santa Fe and Belen aeromagnetic surveys in 1998; Geoterrex-Dighem collected aeromagnetic data as part of the Cochiti time-domain electromagnetic survey in 1997.
The data files and information about their formats and use are organized into three directories plus the PDF file, all listed on the right-hand side of this page. Files pertaining to the gridded data are contained in the "grids" folder; files pertaining to the flight-line data are contained in the "linedata" folder; and files pertaining to the color shaded-relief images are contained in the "images" folder. In each folder, ASCII files with the extension .txt describe the format and contents of the data files. Read the .txt files before using the data files.
