Two-Way Non-Scrolling Regions for Large Maps & Tables

A big map just won't fit on your average monitor. It's easy to lose your points of reference. Smaller maps are often insufficient. Large tables are worse. If you lose sight of the column or row names, you're lost. It's a bad case of tunnel vision.

 

Here, we used the same tools we used for our non-scrolling headers and footers to build dual-scrolling latitude and longitude gifs for a large map. We built a similar page for a very large table. These scripts work for both IE 4.0 & NetScape 4.0 and later.

Big Maps: The first example is a map of beautiful Ireland that's 1000 x 1256 pixels. It takes a bit to download, so be patient. You'll notice, once everything is in place, that the edge of each ruler is transparent, allowing the red latitude and longitude marks to extend onto the map. As you move about the island, notice the map's latitude and longitude are always in synch with the rulers.

Lemme see that map!

Really Big Tables: The second example is a very large table. These kinds of tables are more difficult to view onscreen. We scroll about, and we lose the titles once we move into the middle of the table. We get tunnel vision, and the data loses its meaning. In this demo, columns and row titles scroll with the cells in one direction, and don't scroll in the other. You always know where you are, and what the numbers mean.

This table is about six feet wide, and pretty darned tall.
