Hello<br><br>I have got a global sesimic tomgraphy grid loaded as a .pvd file (see attached) and it accurately plots the data comprising 56 layers as a structured grid:<br><br>Statistics<br><br>Type: Structured (Curvilinear) Grid<br>Number of cells: 3564000<br>Number of points: 3659096<br>Memory: 1.1e+02 Mb<br><br>Data arrays<br><br>Anomaly (-6.7043, 6.879)<br><br>Extents<br><br>X Extent: -180 to 180 (dimension 361)<br>Y Extent: -90 to 90 (dimension 181)<br>Z extent: 0 to 55 (dimension 56)<br><br>Bounds<br><br>X range: -180 to 180 (delta 360)<br>Y range: -90 to 90 (delta 180)<br>Z range: 3.58e+03 to 6.33e+03 (delta 2.75e+03)<br><br>The bounds are correct for what I need, i.e. Long, Lat and radius distance (km) from sphere centre. What I need is to change this to XYZ for spherical coordinates.<br>Apparently this should be possible using the calculator but I cannot see the process - any pointers here :)<br><br>What I am hoping to achieve is the data to be a structured grid in spherical geometry.<br><br>Thanks<br><br>Lester<br> </body>
