1. Basic concepts in interpretation of geophysical data (geophysical anomaly; qualitative and quantitative interpretation; forward and inverse modeling)

2. Non-standard cases of gravity measurements and some problems of interpretation (measurements in moving vehicles; anomalies and measurements at sea; underground measurements; problems with reduction density in Bouguer anomalies; pitfalls of interpretation in the plane z = constant)

3. Special methods in interpretation of gravity measurements (determination of anomalous mass; determination of bedrock topography; search for structures of pre-specified shape)

4. Special methods in interpretation of magnetic measurements (reduction to the pole, analytic signal, Euler deconvolution)

5. Data acquisition and data processing in gravity surveys (gravimeter maintenance; gravity stations and grid selection; base station and drift curve calculation; heights determination of gravity stations; calculation of the total and relative Bouguer anomalies; determination of error of measurements)

6. Data acquisition and data processing in magnetic surveys (grid selection; registration of short-time variations of geomagnetic field; determination of the normal geomagnetic field and calculation of ΔT values; determination of the error of measurements)

7. Gravity and magnetic modeling - program GM-SYS (basic principles; input data; gravity model; magnetic model; simultaneous modeling of gravity and magnetic data)

8. Gravity and magnetic image of the Czech Republic (geological and structural units in Central Europe and their geophysical images; gravity and magnetic maps of the Czech Republic; geological interpretation of major gravity and magnetic structures on the territory of the Czech Republic).

9. Examples of interpretation of gravity and magnetic measurements
