Quick Reference Guide
Most users are probably aware of the Quick Reference Guide in the Cheat Sheets. It lists all the mXrap shortcuts and hotkeys but it is spread over a few pages and can be a bit tough to find what you’re looking for. Below is a one-page Quick Reference Guide for more of a visual lookup […]
To a/b, or not to a/b
The a/b value is sometimes used as a measure of seismic hazard but there are some common mistakes made with this analysis and interpretation. What is a/b? The Gutenberg-Richter distribution is a statistical model that describes a log-linear relationship between the number of events, N, exceeding magnitude, M. log10 N = a – bM At N […]
3D distance measuring tool
You can now measure distances in any 3D view in mXrap (version 5.6.0 or later) with the ruler tool in the Annotations tab. The “Annotations tool” training video goes through all the features and the operation. Most operations will probably be for the distance between two points, such as the event-to-survey distance below. You can […]
Changes to mXrap interface – right-hand-side panels
There have been some interface changes made to the mXrap software in versions 5.6.6 or later. The right-hand-side controls have had a bit of a face-lift and now there are separate coloured tabs for exporting, selections, annotations and clipping. The 3D Controls button has also been moved above the series window and the buttons in […]
Updates to survey importing
If you have updated your software to 5.4.0 or higher, you may have noticed some changes to the Survey Import tool. The Survey Setup training video has been updated. The main changes have been to support additional properties from DXF files. DXF text Text objects from DXF files can now be imported into mXrap and […]
What survey formats can be imported into mXrap?
mXrap supports the following survey formats to be used in 3D views: DCF, VDCL (Deswik) DXF (AutoCAD .dxf) DTM / STR (Surpac .dtm/.str) PNT (.pnt) INP (Map3D Geometry .inp files) Our preferred format if you are using Deswik is DCF. These files are more compact than DXF exports, and your attribute information can be imported […]
Frequency-magnitude chart anatomy
When you are using the frequency-magnitude chart, it can be easy to forget it is log scale and this can distort a few things. Consider the chart below; have you ever thought the Gutenberg-Richter distribution doesn’t look right? Think it isn’t matching the large events very well? The Gutenberg-Richter distribution is a statistical model of […]
Fun and games with mXrap
If you were wondering what a bored Xman does in their free time, this might give you an indication….. You should know by now that mXrap is very flexible and apps can be developed to perform a very wide range of functions. If you were doubting that, this might change your mind 🙂 Ever played […]
What’s the difference between updating the mXrap software and updating the root folder?
Some things you see in mXrap are properties of the software, while other things are properties of the root folder. We often use the software Excel as an analogy. Excel has many built-in capabilities with endless possibilities for creating specific calculations. The software has powerful capabilities, but without a user constructing the spreadsheet, the power and […]
Why aren’t my events updating?
If you notice that you are not getting updated events in mXrap, there are a few possible explanations. In order to troubleshoot the problem, it is good to know exactly how your events are transferred from your seismic database, into mXrap. The first thing to check is if the events are just being filtered out. […]
