Grids and Graticules
MAPublisher Grids and Graticules is a powerful tool. There are dozens of settings to create an indexed grid, measured grid, or graticule exactly the way you want. We often receive questions about how to create certain grid and graticule styles and this was interesting. We were asked how to create a graticule to display a very specific latitude and longitude, perhaps even by itself (only a single line of latitude or longitude).
A graticule is the network of lines of latitude and longitude drawn at regular intervals on a map. Graticules are created in MAPublisher using the Grids and Graticules tool. In some maps, you may want to limit the area on the map that a graticule covers. For example, you may want it to cover only the map’s area of interest. The image below is a map of North America with a graticule drawn at 5-degree intervals. US State boundaries are drawn in white. In this post, we'll modify the graticule three times so it conforms to the edges of the image, so it covers only the Continental United States, and lastly a combination of the previous two modifications.
Ever have the problem that you want to make a map and you are waiting on the final extent or scale, but you want to get started adding data and working on the layout? Here are a couple of tips to make your life easier.
In MAPublisher, the grid bound is the visual extent of the grid or graticule. The grid constraint is the geographic extent of the grid or graticule. It may be a little confusing since both grid bound and grid constraint are defined by coordinate values. In terms of hierarchy, think of the grid bound as the overall container of the grid and the constraint as being contained within the bound.
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.
