Planning and Designing Maps
Creating a Design Spreadsheet
One very effective technique for keeping track of all your data for a map is to
create a spreadsheet of all of the layers you create, consisting of the legend
layer name, which data sources they reference, the display range, and display
styles, such as color or line style, and notes. For example, you could create a
spreadsheet or table that looks something like this:
In this example, there are four layers. The first two layers use different data
to show the same area at different levels of detail when zoomed in or out. The
second two are set up the same way. Note that the first and third layers use
the same SDF, and the second and fourth layers use the same SDF. As you
might imagine, as you start adding several layers to achieve different results
at various scale ranges, it can become difficult to manage the process, so
taking an organized approach is critical during planning. In addition to the
columns shown in the example, you could also add columns that indicate
which server each layer uses, whether it is selectable, the layer type, the layer
group to which a particular layer belongs, and more.
