15. Hold down the Ctrl key and click on each of the five layers, so they are all selected. Right-click
on one layer and select Create Layer Package. In the window that emerges verify that your five
layers are Included. Click Save package to file (rather than uploading it to ArcGIS). Browse
to ___IGIS-Arc_ YourInitials \River and provide the file name First_Layer_Package_ YourInitials .
lpk. Click Save. In the Layer Package window, click Item Description. For the Summary type
Hodgepodge_ YourInitials. For tags type GPS, Ford, Roads, DOQ, DEM. For Description type IGIS
Exercise 3-7. Click Analyze and hope for no errors. If there are any, you can click the Error
symbol and take the appropriate remedial action. Dismiss the Prepare window. Click Share.
Wait until the progress window says Succeeded. Click OK.
16. Start ArcMap with a new, blank map, without saving. In ArcCatalog (either the sidebar or the
program) look for First_Layer_Package_ YourInitials . (You may have to refresh the Catalog Tree:
Highlight ___IGIS-Arc_ YourInitials , right-click on the folder, and click Refresh.)
17. Getting a layer package into ArcMap is, candidly, a little weird. You can't Open it. You can't add
it as data. But you can drag it from ArcCatalog into ArcMap—either the T/C area or the map
area. Once you do you will see a map of the five layers, at its full extent. The attribute data
is there as well. Open the Attribute table of Boat_SP83 to check it. Close the table. Dismiss
ArcMap, without saving. Obviously there is no need to save anything, since you have it all
wrapped up in a layer package.
The layer package you have just made and tested is simply a file with an LPK extension. You can email it,
put it in your favorite cloud, transfer it to a flash/thumb drive—in other words treat it as just a file that you
can transfer to anyone who can run ArcGIS Desktop. That person can access all the information, using the
symbology that you set up. Basically the problem of easily transferring ArcGIS data is solved!
Styles
Styles basically let you draw maps using colors, symbols, and patterns developed by other people and
organizations. When you have drawn maps before, you have been using a style developed by ESRI. In
fact, it is difficult to separate the software, which basically lets you draw points, lines, and polygons—
admittedly in myriad colors—from the ESRI predeveloped symbols. Let's start your understanding of styles
by eliminating all of them.
18. In ArcMap, enter Data View and click the New Map File icon on the Standard toolbar to start
with a Blank Map. Add the polygon component of the coverage SOME_POLYGONS, which you
will find in the
___IGIS-Arc_ YourInitials \Trivial_GIS_Datasets.
folder. Set the T/C tab to List By Drawing Order.
19. Set the software so that it uses no styles at all, by clicking Customize > Style Manager to bring up
the Style Manager window. Click the Styles button to bring up the Styles References window. Clear
all the boxes you can. Which one can't you clear? _______________________. Click OK. Click Close.
20. In the T/C, right-click the polygon symbol. You may recall that that usually that brings up an
array of distinct colors (e.g., Medium Apple, Sodalite Blue, Mars Red, and so on). However,
those are part of the ESRI style. At the bottom of the box, click More Colors. Now what you
have is the Color Selector window, which you met in Chapter 2. It lets you select any color
