Loading Raster Data

Each raster image file requires a raster registration file in SIF, DRA, LIC, or XML format.

To load raster data

Open LOGarc Utilities.
On the right side of the screen, select the Raster tab.
Using the explorer tree on the left side of the screen, browse to the folder which contains the required Raster files. To search for all files within a folder tree, place a check mark beside Sub Folders.
Click Display Files.
LOGarc Utilities will display a list of all the registration files (i.e. SIF, DRA or LIC) files found in the specified location. Note that the associated image files will not be displayed.
Ensure the columns are populated with the correct information.

Some of the columns such as Source and Donor are populated from the Drop Down lists in the configuration screens. Other columns can be populated manually.

To manually enter or select a column heading, place your cursor inside the field and then enter the text.
Select each Raster file you want to load or click Select All.
If you want to delete the successfully loaded Raster files from the original folder, select Delete Original(s).
If a single file in the file(s) you selected contain multiple DRAs you can select Scan for Multi-DRAs. See details below
Click Start LOAD. As the files are being processed, the UWI and Status fields populate.
To view the log files for Raster files that failed to load, open the folder you specified in the Log File tab when you configured LOGarc Utilities. See Configuring LOGarc Utilities for details.

Scan for Multi-DRAs

When selected, the loading function scans the calibration files before loading to identify DRA files that contain calibrations for multiple images. If yes, the application parses out the calibrations and creates separate DRA files for each image.

The sources of multi-image DRAs are direct exports from GeoGraphix or LogSleuth of a single composite DRA for multiple wells, an entire project or AOI, or a similar export with one DRA per well.

If you know that the files that you are loading came from none of these sources, you do not need to select this option.

For small numbers of calibration files (a few hundred or less) this pre-loading scan is fairly quick. However, if the raster/calibration files selected for loading number in the tens of thousands, this scan can take as much as an hour or more.
