The explore tool combines navigation and identification into a single tool. Clicking and dragging pans the map around, and clicking a feature displays information from the database.
- [Instructor] Now that our project has started, it's probably a good idea to get a feel for navigating around the map. The view I have on the screen right now is great for getting an overview of North America, but I'd like to zoom in to give different areas a closer look, and also zoom out to get a global perspective. To do this, we'll take a look at the map tap on the ribbon, and specifically focus our attention on the tools in the navigate group. The first tool is the explore tool. The explore tool combines navigation and identification into a single tool. If you're familiar with the identify tool in ArcMap, you'll know that clicking on a feature in the map will bring up a window that displays attributes.
Now, at this point, we don't have any data. We only have this background base map image. So I'll come back to the identification functionality later on in the course. What we can do with the explore tool, though, is click and drag around on the map to pan it around to different locations. If you click and drag up, you'll move the map northward. If you click and drag down, you'll move it southward. You can get the same functionality by using the arrow keys on your keyboard. So if I press the up arrow key, it'll nudge the map up, and if I press the down arrow key it'll nudge it down, and we can do the same going left or right.
Another keyboard trick that we can use is to hold down the Q key on your keyboard. Now, when I do that, it's going to take a look at the current location of my mouse cursor. So, I'm going to move my mouse right to the center of the screen, and then I'm going to press and hold the Q key. Now, as I move my mouse around to get it farther away from the starting location, you'll notice that the map starts to pan around. The farther away that my mouse gets from its starting location, the faster the map pans. I can use this to kind of roam around the map. So I'm still holding the Q key down and just moving my mouse around in different directions around the point that I started with.
That's kind of a fun way to navigate around the map. Now, we can also zoom in and out of the map. With the explore tool still activated, we can use the scroll wheel on our mouse to zoom in our out. Now, my mouse is actually very sensitive right now, so I don't actually get good results with this, but depending on your settings, you might get a better feel for how this zooms in and out. A more controlled option is to use these two options on the navigate group, fixed zoom in and fixed zoom out. These will zoom the map in to the center point of the current screen. So I can click fixed zoom in to zoom in a little bit, and fixed zoom out to incrementally zoom out.
We can also use the plus and minus keys on our keyboard to get the same result. I can zoom out using the minus key and zoom in using the plus key. If I want to see the entire extent of my data, I'll press this globe icon in the navigate group. That'll zoom out to the full extent of all the data that I currently have on the map. You can also press the insert key on your keyboard to activate the full extent option. Below the fixed zoom in and fixed zoom out buttons are options to go to the previous extent, and then go to the next extent. If I press previous extent, it's going to go back to where I started a moment ago, and we can toggle back and forth between these two different views.
Then I can go to a different location. Let's go ahead and pan the map around a little bit and do some zooming in. Then I'll press the full extent button again, and you can see I can toggle back and forth between these two views. The keyboard shortcuts for the previous and next extent options are to press the angle brackets, which are actually the period and comma keys on your keyboard. If I press the left angle bracket, you'll go to the previous extent, and if I press the right angle bracket, you'll go to the next extent. There's a couple of additional ways that we can zoom in our map. If I press and hold the shift key on my keyboard, you'll notice that I get this icon that represents a magnifying glass with a plus symbol in it.
Now, if I click my mouse, I will center the map on the area that I clicked in and zoom in at the same time. So, for instance, if I hold down the shift key and then click on the state of Florida here, it's going to center Florida into the map and zoom into it. And we can continue to zoom in to that area by clicking and holding down the shift key. Another way to zoom in is to hold the shift key down and then click and drag out a rectangle. That'll create an area, or a box on the screen, and when I let go of the left mouse key, it'll zoom in to that area that I drew the rectangle around.
Finally, I can hold down the control key on my keyboard and simply click to center the map without zooming in or out on the area that I clicked on. Let's go ahead and go back out to the full extent of the map by pressing the button on the navigate group. A couple of other shortcut keys that I want to show you. If you hold down the A key, that'll rotate my map in a clockwise direction, and if I hold down the D key, that'll rotate my map view counterclockwise. And if I want to straighten my map out again, just tap the N key, and that'll orient the map so that north is up.
Now, there might come a point where you want to save different locations so you can return to them. Let's go ahead and hold down the shift key, and I'm going to zoom into North America again just by clicking and dragging out a rectangle. And then what we can do is create something called a bookmark. I'll come up to the bookmarks button on the navigate group, and click on it once, and then we'll choose new bookmark. This'll create a saved location that we can return to again. I'm going to call this North America. And we'll press okay, and if we go back to our bookmarks, you'll see that we have a new bookmark for North America.
Let's go ahead and click off of that, and we'll use the Q key to kind of roam around a little bit. We'll find another area we want to look at. I'll come over here to Europe, and we'll go up just a little bit more, and we'll go ahead and save a bookmark for this. Once again, I'll go to the bookmarks option, and choose new bookmark, and we'll call this one Europe. Now, if I want to return to these two locations, I've got two different bookmarks. If I click on North America, it'll zoom back to that, and if I click on Europe, it'll go to that view. So getting around the map view is an essential skill.
With a little practice with the keyboard shortcuts, you'll quickly be able to navigate to any area that interests you. And, by saving bookmarks of important locations, you can jump back to them at any time.
