How completely do various technologies nowadays map how much there is of various kinds of physical matter to be found at various locations within the space defined by the coordinate systems in use? What are the technologies now in play to address these questions and how well do they do? Can you point me to papers that address these questions or provide me with a more or less comprehensive view of the state of the art in these regards, please?
if you have point data of various place can be generated in form of spatial pattern.
first you have to know all point data with its coordinate.
in excel you can write latitude and longitude place name value etc can be brought into arc gis. then you have to chose interpolation technique which is given above in website with various technique.
Thanks for your response @Firoz Ahmad. :-) But the geography I am speaking of is not the kind that deals in Lat & Long. I deal in Refractivity (unitless) and Wavelength (λ, nm) and plot probability levels on the Z axis. I speak of statistical density functions that map the density of matter in space, which trends with Refractivity. Both Density and Refractive Index (RI) trend with compositions of minerals. That's my game. I'm seriously wondering (without knowing enough) whether there are any other techniques that can map the minerals in a rock sample with anything like the precision and accuracy I can demonstrate from my own work. For instance, do researchers using Raman and Mie spectroscopy map things similarly to what I do? What about information from lasers or back-scatter γ radiation? I am much too ignorant about "competing" technologies such as what is learned from Electron Microscopy, and so on. So I am seriously asking what others can do to map the probability levels of density/RI in the transparent-mineral phases of a rock or anything else. Thank you for your interest! -Steve-
