Now that we’re late into the summer, most of you will at some point hear your kid or a neighbor’s shout, “Ready or not, here I come!” as they joyfully run around the yard looking for their hiding friends. If you’re anything like me, you wistfully look at them and think, “I wish finding my layer data in GIS was as much fun as these kids are having.” Okay, so maybe nobody really thinks that, but it was a good segue into this week’s post on how to find layers that might be hiding.
This post is an expansion on a previous article regarding layer visibility. I’d recommend reading it or at least being familiar with the concept of layer visibility before continuing with this week’s post.
Some layers only have their data visible when zoomed to an appropriate scale. For example, the Cemeteries layer will show nothing but its name when zoomed out. This is because only some Cemetery Text is within the visible scale.
To view the layer’s data, you must either zoom in by hand until you are at the appropriate scale, or use the Zoom To Visible Scale feature. To access this feature, first click on the right arrow icon next to the layer you wish to zoom to.
The options presented let you navigate your selected layer in two different ways. The first, Zoom to Full Extent, will zoom to a location and extent that fully encompasses all the data in your layer. This is useful for zooming out to see all of a layer. The second option, Zoom to Visible Scale, will zoom you in to the proper extent to view your layer.
Try these options out and see if you can better find some of your hiding data. See you next Tuesday!
