Merge Two Digital LAS Files into One

This web application allows the user to merge two files into one. The design of this web application was to provide a 4 step process in combining two LAS Files.

  1. The user selects the "(1) Load 2 LAS Files" Button to load each file into the Merge LAS File Web App. The user will only be allowed to do two digital LAS Files at a time. The Program assumes LOG ASCII STANDARD - VERSION 2.0 for the digital LAS Files.
  2. The user then selects the "(2) Modify LAS Header" Button to select which digital LAS File Header to start from and to insert any missing data. The user then selects the "Done" Button at the bottom of the dialog and the header information is automatically transferred to the program.
  3. The user then selects the curves they wish in the New LAS File by selecting the "(3) Select Curves" Button. The user has the option to use the Mnemonics used in the original files or to use the KGS standard Mnemonics for the LAS File Curves. This dialog provides a table containing the KGS Standard Mnemonic name for the LAS curves. The user can then select the radio buttons next to the curve mnemonic of each curve from each file they wish to appear in the new LAS file. Once the user is done they only need to select the "Done" Button and the curve information will automatically be transferred.
  4. The fourth and last thing they need to do is select the "(4) Create new LAS File" Button and a dialog will display to request a filename for the new LAS File. The new LAS File will appear in the new directory.

In merging the LAS Files there are a number of depth step size combinations that the web app is designed to handle,
