Importing sample locations for interpolation

Versions 1.4 and later.

This is only to be used when sampling is not completed in the Veris software. By

following these steps the user could map a field and then flag the GPS locations where

samples were collected and use those locations to get the interpolated values from the

Veris software.

Step 1: Collect field data, then extract and filter the data. Exit the Veris

Spectrophotometer Software once these steps have been completed.

Step 2: Create a file of the GPS coordinates of the sampled locations. The file should

be created in the following format. Column A is the sample number, column B is the

longitude, and column C is the latitude. Save the file as actual locations.txt in the

working directory, where the field data has been stored.

Example of actual locations.txt file

Step 3: Open the Veris Spectrophotometer Software and chose interpolation. The

software will use the locations stored in the actual locations.txt file, and give an

interpolated spectra, and auxiliary data for each location. The output will be a file called

[email protected], which will be created in the working directory.
