Chapter 4 started out by explaining the basics of ArcCatalog.   We learned how to access different information and how to navigate through the files.  ArcCatalog allows its user to search through data layers.  Once data is identified, it can be relocated and added to ArcView maps.  For example, the base layer of the blue sea floor was our original map, the planned and diverged flight paths of Earhart were added by moving the diverging flight path layer from one file in ArcCatalog to the active file in ArcView.  This allows the user to combine useful information.

In Chapter 18 exercise d, I exported a map in two different image file formats.  The bitmap is 2,525 KB, and the JPEG is 356 KB.  Because I want my web pages to load quickly, I will use the smaller image file below.

The image has such a low resolution and large pixel size because the export process has lowered the number of pixels in the image.  This map was obtained by enlarging a portion of a larger map. This process has decreased the clarity of the image.  The image can't be better than the original image but it can be less crisp than  due to the exporting and resizing process.
