Intrepid Workshop - ASEG PESA
G1: Tensor Processing: Gradient Processing
This course provides participants with an introduction to quality control, gridding and filtering of vector and full tensor datasets. You will learn to assess the quality of a tensor survey, interpret tensor data and optimise the signal content through linear differential de-noising [MITRE] and other methods.
Saturday 21 August 2010
8.30 am - 5 pm
Crowne Plaza, Darling Harbour

GeoModeller Workshop - ASEG PESA
G6: GeoModeller: Building a 3D Geology Model - Reconciled with Gravity / Magnetic Tensor Data
This one day workshop will initially introduce the 3D GeoModeller approach to building a 3D geology model. Users will add new geology data, and revise their interpretive ideas, and will learn that geology models can be easily revised and improved.
Friday 27 August 2010
8.30 am - 5 pm
Crowne Plaza, Darling Harbour

Reduction and Levelling

Spike Detection
Data reduction
Complete data reduction services are available. Spatial and temporal coherence of surveys are checked. Flight lines are edited and clipped. Survey data is checked for noise and spikes. Automatic or manual spike detection and removal is completed using a Profile Editor. Heading, Parallax, Diurnal, IGRF and Navigation problems are corrected as required.
Tie Lines
Advanced levelling
There are two levelling methods, tie line based levelling and microlevelling. Tie line levelling methods include polynomial fitting to error estimates, and also loop closure levelling. These methods have been used successfully on a wide range of potential field datasets from many different sources.
Other available methods include cross over analysis, rejection of bad outliers to improve the "goodness-of-fit", pseudo-tie line levelling for poorly acquired surveys. Full tensor levelling is current development work.
With new vector and tensor data-sets, we are offering to analyse using the survey data itself for a range of systematic errors that commonly occur. In particular vector gradient heading errors in the four principal flying directions can be estimated and used to remove this effect. In a similar manner the self-weight of effects in gradient tensor data can also be removed.
Decorrugation
Decorrugation and microlevelling
Decorrugation and microlevelling allow finer improvements to data, and are also used where tie line based operations are not possible. Re-levelling of older surveys is one of our specialty areas. INTREPID microlevelling methods have been applied with great success on a very diverse range of data sets.
