ERT data for the survey at Tapo E.S., eastern Taiwan

The zip file contains two files: the .urf file for the resistance data and the .trn file for the terrain data. The file format is described in the followings:

A 2D sample Universal Resistivity data File (URF)
Top two lines are comments and the third line defines the length unit.
Unit: meters
;This file is used for illustration of URF file format only.
;Any line starting with a semicolon (;) is a comment line

;A line starting with a colon (:) defines a section header.
;A section header is required and must be spelled correctly.
;A blank line will be ignored
;Data entries are comma-separated.
;Electrode locations are defined with XYZ coordinates.
;Z = 0 on the surface and negative downwards
