Map Calculator

Introduction

The Map Calculator can be used to calculate none equidistant matrices from measured maps or create a new channels in a given NC2 data file.

Matrix Calculation

The map can be saved as INCA-CSV file, a DAMOS file or as a Magneti-Marelli-CSV file.

The map can be inserted into the clipboard. From the clipboard can it can be inserted into an Excel sheet.

To calculate the matrix the selected interpolation method is used. If you need extrapolation, it is recommended to use the Thin-Plate-Spline method. See Data=>Interpolation.

Z-Channel Calculation

This command can be used to calculate for a x- and y-channel for a given NC file a new z-channel. The z-coordinates are interpolated for the given map. The new channel is saved in the NC file. If extrapolation is disabled, the z-coordinates for data points outside the convex hull are set to missing.

If the x- and y-channels have different number of data points, the new channel will be added to the dimension with the higher number of data points. This problem can occur with MDF files, were the x-and y-channels belong to different time groups.

Installation

The installed files are located in the C:\Program Files\UniPlot\AddIn\RS_3DCAL directory.

Usage

  • Import a 3D dataset.
  • Select the dataset.
  • Choose Data=>More Data Functions. Choose the function “Map-Calculator” or right click the data set and choose the command “Map-Calculator”.
  • In the following dialog box define the column and row values. Use a semicolon (;) or a comma (,) to separate the values.
  • Choose OK.
  • You will be asked for a file name to save the matrix. You can save the matrix as a Text-, Excel-, VS100/INCA Magneti-Marelli file or as a DAMOS file.
