-<p>CHARISMA-GPR creates a 2-dimensional grid space based on the user input and fill up this space with the multiple GPR scans. In our software, you have the flexibility to define the x and y directions of the 2D contour map based on your perspective of the scan area. Since the orientation may vary depending on where you stand, you can choose which direction corresponds to the x and y axes. For example, if you are standing on the north side looking south, you might decide that the x-axis runs west to east, and the y-axis runs north to south. However, if you change your position—say, standing on the south side looking north—your definition of the x and y axes will flip. This shift in perspective can cause confusion if the directionalities aren’t clearly defined based on your view. To avoid this, we’ve made the configuration flexible, allowing you to set the axes according to your unique viewpoint, ensuring a user-friendly experience and enhanced accessibility regardless of your orientation in the field.</p>
-<p>After defining these axes, you’ll select the scan origin, which is the starting point for the GPR scans. The origin can be any of the four corners of the rectangular area, depending on your setup. Once the axes and origin are set, you’ll choose the scan direction, which can either follow the x-axis or y-axis. Since there are four possible origins and two scan directions for each, there are eight potential configurations for how the grid is filled. Based on your selections, the software will process the GPR data and generate the 2D contour map accordingly, ensuring that the output matches your defined setup and perspective.</p>
+<p>CHARISMA-GPR assumes a rectangular grid layout with linear GPR scans to generate a contour map. It accepts multiple GPR scan files in one directory, each representing a linear scan taken at regular intervals. These files will be processed to fill the grid space and create a contour map through interpolation.</p>
+<p>We follow standard frameworks developed by ASTM and AASHTO. The data collection methods and device settings are well established in the documents. However, still, there are some unclear or vague statements in the data processing part, that lead to subjective interpretation. To address this, we conducted a comprehensive literature review on GPR data processing and selected only the most widely accepted and commonly used steps. Our software achieves full automation by following the necessary framework (time-zero, background removal, migration, dielectric constant characterization, and rebar mapping). Each step will use a fixed algorithm to output a consistent result.</p>

 <li><p><strong>Single Channel Requirement</strong>: Currently, CHARISMA-GPR does not support multiple-channel DZT files. It only accepts a series of DZT files containing single linear scans.</p></li>
 <li><p><strong>Rebar Mapping Algorithm</strong>: The software employs the F-K migration algorithm for rebar mapping, which assumes that the dielectric constant of the subsurface materials remains constant throughout the entire area.</p></li>
