Do you have some data you would like to divide into multiple layers using unique values in an attribute? If so, you might want to try using the Split Layer feature in MAPublisher.
For example, we have a MAP Layer of the world (world_area layer). The world_area layer has many attributes and one of the attributes is about “Continent” information. With the “Continent” attribute, there are eight unique values: 1) Africa, 2) Antarctica, 3) Asia, 4) Australia, 5) Europe, 6) North America, 7) Oceania, and 8) South America.
To split this world_area layer into eight different layers based on unique values in the “Continent” attribute, we simply specify the Continent layer in the Split Layer dialog box.
Open the Split Layer dialog box. Choose the world_area source layer, then select the option “Split art to new layer(s) by unique attribute value:”. If you have a specific word you would like to include with the eight layers, enter the value for the “New layer prefix” option. Here, we entered the word “continent” as the prefix.
Now you have eight new MAP layers created based on the unique values of the “Continent” attribute. The attribute scheme, structure, and attribute values are inherited from the source layer to the split layers.
In a previous blog about Grids and Graticules, we quickly introduced one of the major features of the new Grid and Graticule tool. We’d like to share another major feature when creating grids: creating grids with an alternative coordinate system.
For example, the MAP View has a coordinate system “NAD 83 / UTM zone 17N” (in metres). You might want to make grid lines with the same coordinate system but in different units. You can do so by creating a custom coordinate system and then specifying the desired unit (US Foot, for this example), then creating a grid based on custom coordinate system. In this example, a grid with NAD83/UTM zone 17N (metres) coordinate system is created in the blue colour. Another grid with a NAD83/UTM zone 17N (USFoot) custom coordinate system is created with the orange colour.
Likewise, you can create multiple sets of measured grids with different coordinate systems in one MAP View (e.g. one set with NAD83 UTM, another with NAD27 UTM, another with some other local coordinate system) without the need to transform the MAP View.
A little known (but very useful) feature is the Attribute Tear-Off Panel which is located in the upper-right corner of the MAP Attribute panel (available in MAPublisher that’s compatible with Adobe Illustrator CS6 or higher). Use it to help you edit and view attributes even when they are deselected. It is very handy when used to compare attributes of different datasets.
Simply click the Attribute Tear-Off Panel icon to open another MAP Attribute panel. There are a few key difference between MAP Attribute panel and Tear-off panel:
1) The tear-off panel does not have any MAP Attribute functions (e.g. Join Tables, Find and Replace, Edit Schema, etc).
2) The tear-off panel view remains active and shows attributes even after features are deselected.
If your data values are updated within MAP Attribute panel, click the Attribute Tear-Off Panel again to update the values in the tear-off panel.
