Data from selected sites can be output to files on your harddisk for
further analysis outside of PaleoVu. For georeferenced data, PaleoVu
can output a columnar ASCII format with spaces, commas or tabs
separating the columns. Time-slice image data can be exported in NetCDF
and ASCII Special.|
6.1. Exporting Georeference Data
Any set of data sites can be exported through the Export button of the SITE LISTING window. When the Export button of the SITE LISTING window is clicked, you are presented with the EXPORT DATA SET dialog.
The ASCII files created will carry the same eight character file names as the PaleoVu data site file name with the extension ".out" or an extension of your choice added. The EXPORT DATA SET dialog allows you to set the output directory. It also allows you to specify whether or not header information will be output. Furthermore, any combination of variables may be exported.
An example of exporting Ice Core Data Sites follows:
- Create the SITE LISTING window by clicking the List Sites
button of the GEOREFERENCE WINDOW.
- From the SITE LISTING window, click on the sites that you
want to export. In this case Vostok and Quelccaya Core 1
are selected for export.
- Click the Export button.
- The EXPORT dialog (above) will now be displayed. A
description of each EXPORT dialog component and examples of using each
to export Ice core data follow:
- Output Directory Text Box
- Enter the target directory for the exported data here. In the above example all the export files will be put into the D:\GEODAT directory.
- Column Delimiter List Box
- Click on the arrow on the right side of this box to see a drop-down menu with your column delimiter options. Select from tabs, spaces or commas.
- Output File Extension Text Box
- Enter the file extension for the file(s) you are exporting. By default the files will be given their filename with a .out suffix. This text box is also used for naming the export file if you are exporting multiple sites into one file. A file containing multiple sites will be named allsites.out by default.
- MULTIPLE files or all sites in ONE file selection box
- If you are exporting the data from more than one site, you have the option of having one file containing all the data sets or a separate file for each data set.
- Define Header Variables To Be Exported
- Click this button when you are ready to decide which of the header variables, such as latitude, longitude and elevation, you would like to have exported at the top of the file along with the georeference data from the site. The variable lists at the bottom of the dialog box will be used for this selection process.
- Define Vector Variables To Be Exported
- Click this button to begin selecting which columns of data to export from the sites selected. The variable lists below will be used for this process.
- Variables To Export List and Variables NOT To Export List
- The Variables to Export list displays all variables that will be exported. The Variables NOT to Export list displays all the variables that you choose not to export. The variable list titles also indicate whether you are working with Header variables or Vector variables. For instance the example dialog box above is set for the selection of vector variables.
The button displaying a right pointing arrow (right arrow button), the button displaying a left pointing arrow (left arrow button), and the two ALL buttons allow you to move variables between the two lists.
To move a group of variables (or one variable) from one list to the other, select the variables that you wish to move, and click on the arrow button that points in the direction of the target list. To move an entire list select the ALL button with the appropriately directed arrow for the direction of your move. For example, the ALL button would move every variable from the Export list to the NOT To Export list.
