Hi Praveen, geographically speaking what you call Y is Z, the vertical, if I understood what you say. Your profile seems to be leading on the X/Y surface (the horizontal), right? There are some issue that are important for geological sections, especially in medium to small scale (ex 1:25.000-1:5:000), for instance those points, projected firs tto the section and than to the profile might show situation which are not on the surface but underground. If you project them on the surface you bring a geometrical error on the rapresentation of the structures. Second problem is what I wrote before, to take into account the strike of the bodies which cannot be perpendicular to the section. There are other question too that make me not sure if a simple ortogonal projection tool can be useful for geological sections. Anyhow I leave the other OJ member to give their opinion about that. There is a "dirty" way to obtain what you need a) add geographical Z as a separate attruibute to all your points and project them to the line c) for each point add the distance from the star point as a separate attribute (ex L) d) save the layer as TEXT file e) reload the file using a CVS plugin into Openjump and choose Z attribuite as Y and L attribute as X The pointss will be reprojected at the right distance from the start point of the section and at the right deep (or altitude) from the surface line NOTE that the profile has to be build using the same tecnique.
After drawing your geological section using OJ as a cad drawing software you can export the section as DXF I hope I was clear regards Peppe 2013/1/2 Praveen Sinha <pks...@yahoo.com> > Hi, > Actually, I mean orthogonal (verticaly up and not with inclination= in > proximity it does acquire an inclined path) translation of the intersection > points ( between section line and the lithology polygon layer (rotated to > horizontal X varies from point to point but Y is constant)) to a curved > profile line (developed on the section line ). > > This is not to develop a geographic layer but just to improvise the > co-ordinated space of the display device of OJ to draw a geological section. > > Find attached a drawing to understand the point, I am driving at.
