Hi, I have used above two tools. Thanks a lot for those in advance. I did the following: 1) las2txt -i a.las -o coordinates.txt -parse xyz 2) las2tin -i a.las -o triangles.txt
My questions are as follows: 1) Do all the points in coordinates.txt should be appearing in triangles.txt? I.e. for example if in coordinates.txt I have the following: x0 y0 z0 x1 y1 z1 x2 y2 z2 ... x100 y100 z100 Where x0,y0,z0,...,z100 are floats. So I assume that in triangles.txt I will only see numbers between 0 and 100 inclusive. Am I right on this? Also can I be 100% sure that all the numbers between 0 and 100 will appear in triangles.txt at least in one triangle? 2) For example currently I have downloaded the following "http://liblas.org/samples/mscst000131.las"; las file... I converted it using your tools above into coordinates.txt and triangles.txt, respectively as it is shown exactly above. But then I run a program which consists of the following code: //program written in c# string[] triangles = File.ReadAllLines("triangles.txt"); string[] coordinates = File.ReadAllLines("coordinates.txt"); long counter; for(long i=0; i<coordinates.Length; i++) { counter = 0; for(long j=0; j<triangles.Length; j++) { string[] str = triangles[j].Trim().Split(' '); if((long.Parse(str[0]==i))||((long.Parse(str[1]==i))||((long.Parse(str[2]==i))) { counter++; } } Console.WriteLine("Line: "+i+", found "+counter+"times."); } Some of the lines are found to be 0 times. It means that not all of the coordinates appear in tins created? Am I doing something wrong? Or is it normal that some of them do not appear in tins generated? Thanks a lot in advance!
