Grant and Lester,
I do primarily geochemistry for processing and display in QGIS, but
occasionally I do a little physical chemistry - aka geophysics ;-)
I’ve been really liking working in R with all the support in there for
visualization, EDA and modelling. For some purposes it could be
Hi Grant,
As a potential fields geophysicist myself, I often do all my
processing using GMT or Mirone,both of which can be used to compute
derivatives via grdfft, including directional and differential RTP
(for your mag). GMT can work with a number of data formats but
primarily netCDF; Mirone has
Hi,
I have no real idea of what you are doing but I think you will need filters to
go from a total magnetic intensity image to a 1VD image. Try to figure
out what these filters are and then Google the filter type with QGIS, Saga or
Grass. Chances are that Saga or Grass have what you need and
I have a total magnetic intensity image and would like to create a first
vertical derivative of the image. I have found the hillshade, slope and
aspect operations and wondered what is the best to use as 1VD process?
