GSNI Data Catalogue
The Tellus airborne electromagnetic survey of Northern Ireland (XYZ Data)
This dataset presents the results of the Tellus Electromagnetic data as xyz data.
Channels in the dataset are:
X: Grid Easting (m)
Y: Grid Northing (m)
LAT: WGS84 latitude in decimal degrees
LONG: WGS84 longitude in decimal degrees
FID: Numerical sum of Julian day and seconds past previous midnight
FLIGHT: Flight number
DATE: Date of survey flight (YYYYMMDD)
DAY: Day number (Julian)
TIME: Time (HHMMSS.SS)
DIR: Flight direction (degrees clockwise)
RALT: Radar altitude (m)
GPS_H: GPS altitude (m) above geoid (WGS84)
DTM: Digital Terrain Model (m)
PLM: Power-line monitor (no units)
RE_LF: EM real (in-phase) component, low frequency (2005: 3125 Hz; 2006: 3005 Hz), ppm
IM_LF: EM imaginary (quadrature) component, low frequency (2005: 3125 Hz; 2006: 3005 Hz), ppm
Low_Freq: Low frequency (2005: 14368; 2006: 11962), Hz
RE_HF: EM real (in-phase) component, high frequency (2005: 14368 Hz; 2006: 11962 Hz), ppm
IM_HF: EM imaginary (quadrature) component, high frequency (2005: 14368 Hz; 2006: 11962 Hz), ppm High_Freq: High frequency (2005: 14368; 2006: 11962), Hz
LFApRes: EM apparent resistivity, low frequency (2005: 3125 Hz; 2006: 3005 Hz), ohm.m
LFDepth: EM apparent depth, low frequency (2005: 3125 Hz; 2006: 3005 Hz), m
HFApRes: EM apparent resistivity, high frequency (2005: 14368 Hz; 2006: 11962 Hz), ohm.m
HFDepth: EM apparent depth, high frequency (2005: 14368 Hz; 2006: 11962 Hz), m
The Tellus survey was funded by the Department of Enterprise, Trade and Investment (DETI), now the Department for the Economy (DfE) in Northern Ireland and the INTERREG IVA programme of the European Union (EU) Regional Development Fund.
