Currently working through the Gravity and terrain correction walk through using the sample data given and when I read in the FreeAir correction the data is not populating with anything. Any advice?
Hi all, I was working on a forward model via GM-SYS and suddenly the curves for the calculated gravity and gravity error disappeared, although in the display they are selected. Does anyone know what is the problem with this? how can I fix it? So far, I tried the following approaches, none of them worked: 1- save the model…
Hi everyone. I would like to ask if anybody can help me with quantifying uncertainity on gravity data I downloaded from the Bureau Gravimetrique International BGI. I know gravity data are affected by a series of uncertainty coming from aquisition (geographic posizion, elevation, drift correction) and processing…
I am looking for documentation for the Geosoft gravity Isostatic Residual tool and for assistance with some questions that I have about the way that the calculations are performed. The only documentation that I can find is an online eLearning tutorial and a short description on the product webpage.…
Since upgrading to v 9.5 I have issues with the Drift Correction. I can not perform a drift correction manually with a click of the button like I could in previous versions. In the Gravity workflow, one has to create or append the location data base BEFORE importing the gravity data. Provided all the correct locations are…
Dear Voxi user I am new user in Voxi earth modeling and have some questions about it. I have gravity data for inversion. I only have topo data to be used for sensor elevation as well as DEM grid, am I right? Normal unconstraint inversion give me voxel file (V1) with data values as -46 to 23.7. Is that normal density or…
Hello, Do we know definitively the units for the Local Correction Distance field? km or m? My gravity station's X,Y and the DEM are in UTM, so meters there. Thanks
I realized that values in MicroGravity are between +1/2 and - 1/2. I guess these values are obtained after removing the mean value from Complete Bouguer values, am I right? for example, if the Complete Bouguer as 15-20 mGal with mean of 17.0, when removing 17 from all data, we get the MicroGravity values.

When using constraints grid in gravity structural inversion, I have basement depth grid from Euler deconvolution and would like to use it as constraints grid, I could not find a way to create such constrain grid. You may have explanation for that issue. regards Essam
