Airborne geophysical survey: Missouri Vertical Intensity Magnetics

Description:
Abstract:
Magnetic data were collected by instruments that recorded vertical-intensity values. Locations were determined by using topographic maps. The best way to represent this data was to create an analog map with contour lines. This dataset is a representation of the digitized contour lines by following the contour lines. The values presented are latitude, longitude, and map vertical- intensity values. Note: Only selected parts of the original map were digitized to fill in around the airborne data.
Purpose:
Aeromagnetic and ground magnetic surveys are used for geophysical prospecting. Some variations in magnetic measurements are caused by rocks that contain significant amounts of magnetic minerals (magnetite being the most common). These anomalies reflect variations in the amount and type of magnetic material and the shape and depth of the body of rock. The features and patterns of magnetic anomalies can also be used to delineate details of subsurface geology including the locations of buried faults and the thickness of surficial sedimentary rocks.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
The data shown on the original map have been processed using various formulas and methods that are not usually documented but that represent industry standard practices for vertical intensity data reduction. Latitude and longitude were derived from existing topographic and other state and local maps. The exact accuracies of these processing steps may not be known.
Logical_Consistency_Report:
The data on the original map were collected by a variety of people who were responsible for collecting and processing the data. Survey layout specified the conditions and specifications under which these data were collected. Standard academic practices of the time were followed in data collection and processing.
Completeness_Report: Data is complete as reasonably digitized from the original map
