airborne_survey(region=None, data_region=(- 5.0, - 4.0, 56.0, 56.5))¶
Create measurement locations for a synthetic airborne survey
The observation points are sampled from the Great Britain total-field magnetic anomaly dataset (see
harmonica.datasets.fetch_britain_magnetic). A portion of the original survey is cut (data_region) and the coordinates may be scaled to the given region.
region (tuple or list (optional)) – Survey horizontal coordinates will be scaled to span this area. The boundaries must be passed in the following order: (
north, …), defined on a geodetic coordinate system and in degrees. Only the 4 horizontal boundaries are used. Subsequent boundaries will be ignored. If
None, the survey points won’t be scaled. Default
data_region (tuple or list (optional)) – Subsection of the original Great Britain magnetic dataset that will be sampled. The boundaries must be passed in the following order: (
north, …), defined on a geodetic coordinate system and in degrees. All subsequent boundaries will be ignored.
pandas.DataFrame) – Dataframe containing the coordinates of the observation points on a geodetic coordinate system. The
pandas.DataFramewill have the following columns:
height. Longitudes and latitudes are in degrees, and heights in meters.
