A freeware code written in C# to view LAS depth based files. It supports version 2 LAS only. Later release will be able to read version 3 also.

This code is written in C# and will require .Net Framework version 2 for execution. Plots can be saved in TIF or PPM formats.

File comment: Here is the standalone executable. Program needs .Net Framework for execution (which normally every Windows based PC has these days)

I don't think that Schlumberger BlueView is able to view LAS. However, Schlumberger DataView is able to view LAS as well as DLIS and CSV.

How did you parse the las files with the c# .net app?

Thanks!

1. Read a line of data. (lets say in string "linedata")
2. linedata= linedata.Trim()
3. linedata = linedata.Replace('\t', '')
4. index = linedata.IndexOf(' ')
5. data = linedata.Substring(0, index) ; datadouble = Double.Parse(data)
6. linedata = linedata.Substring(index)
7. repeat until linedata reads last data.

hope this helps.

Thanks!

Did you ever manage to update your code to support 3.0?

Also. do you have the code by any chance?

I am just trying to convert a las file to a neat looking ascii file.

I never got the time again to work on LAS3.

It would be a task to separate the code so that it converts las to ascii.
