Deep Ground Penetrating Radar Technologies and complementary solutions on needs of some geoenvironments

There are some works of all countries on caving literature...At this point,we can shortly express about presented better condition by oldtimes of "background based on tecnic information"  on chapters as cave mapping.But,despite some technologic developments,there are still some problems...You know that subject some standards developed for cave mapping.In this mean,I realised  a research(Thus,I think that conclusions are very informative for some geoenvironments);

NO ANY STANDARD:

Evaluating as a whole presentations based on first expressions,clearly summarying keyrole of geophysics concept for solution of some problems.You are right!Especially,some geoenvironments will evaluate that I imply to presented perfect supply to needs of some geoenvironments for this type applications of deep ground penetration radar technologies.For more information;

You maybe can wonder about name of this system known as Roteg or RT GPR...This name is summarying characters related of Rudolf Tengler☺

I share a "Carbonate Outcrop Map" considering a condition as discovery detailed big part of World;

Source.https://en.wikipedia.org/wiki/Karst

I realised analysis based on countries included especially selective provinces....Conclusions(Where,I have not considered any alignment.So,you must evaluate that this countries have to selective condition on criteria);
