LAStoDash is a sample Dash project that takes a Log ASCII Standard (LAS) file and builds a web app to view its content and print in PDF format.
As indicated in the LAS 2.0 Specifications, LAS files contain sections that are marked by a ~. The LAS file used for this app contains four of these sections, including version and wrap mode information (~V), well identification (~W), curve information (~C), and ASCII log data (~A), all of which are displayed in some format (e.g. graph, table) in the demo app and the printable report in PDF format.
