How to get consistent quality of vectors when exporting to AI format

By Michael Law, Esri Product Engineer

Exporting to an external graphics package like Adobe Illustrator or Macromedia Freehand from the ArcMap environment can have its challenges. One positive aspect of exporting is the ability to make certain that CMYK values are retained for proper print color reproduction. Some of the challenges you may face after export are inconsistent vector line widths, irregular polygon shapes, and something our programmers call polygon dicing. Continue reading

Creating dash-dot symbols for polygon outlines

By Charlie Frye, Esri Chief Cartographer

Example of a dash-dot line symbol used on boundary lines

Dash-dot line symbols for polygon outlines should be displayed in a way that consistently shows the pattern of dashes and dots and clearly shows the shape of the polygon. In ArcGIS, a multi-layer line symbol is required. One layer is a cartographic line symbol with a dash pattern.  The second is a marker line symbol that shows a marker (the dot) with a complementary pattern to the dashes. Continue reading

Using feature weight rankings to avoid placing labels on major streets

By Charlie Frye, Esri Chief Cartographer

Labeling toolbar with Label Weights button circled.

Notice in the first graphic below that the labels for “CAJON ST” and “CLIFTON CT” are placed over of major streets in a way that makes them difficult to read. This graphic is derived from my recent blog entry on the Maplex Street Placement option, and I was using the Street Placement option, but that left me with this problem. Well, this happened because I didn’t tell the Maplex Label Engine to treat the major streets differently. Continue reading

Tips for exporting to Adobe Illustrator format (AI) so CYMK colors are maintained

By Michael Law, Esri Product Engineer

Color Selector showing the menu that is shown be black triangle button.

For many GIS users and cartographers, the use of external graphics software is a common step in his or her workflow and production of print quality maps. One of ArcMap’s more popular export formats is the Adobe Illustrator (AI) export because of its wide compatibility with a number of graphics software packages. This export format was first made available in ArcGIS 8.1 Service Pack 1 and has been popular ever since. The ArcMap AI exporter has been fully tested to work in Adobe Illustrator CS and CS2. It is currently being tested in CS3 with good initial results. Continue reading

Cartographic settings in the ArcMap Advanced Settings utility

By Aileen Buckley, Mapping Center Lead

Image of ArcMap Advanced Setting Utility

A lot of people don’t know about the ArcMap Advanced Settings utility – it can help you customize some of ArcMap’s default options and as a result make your experience with ArcMap a bit more efficient and personalized.  The executable file that starts the utility is located in your ArcGISUtilities folder.  On my computer, the path is C:Program FilesArcGISUtilities.  Double-click the AdvancedArcMapSettings.exe filename to start the utility.  Here are some options you may find useful on the various tabs: Continue reading

How to symbolize one-way streets

By Charlie Frye, Esri Chief Cartographer

Example of one-way arrows on streets

Indicating that a street is one-way and which way is valid to travel was a lot harder than it should have been prior to version 9.2. At 9.2, the new representations symbology makes this a much faster and easier task. To create this effect, you will need to have your street line data stored in a geodatabase which is a requirement for using representation symbology. Continue reading

What does the Maplex Label Engine’s Street Placement option do?

By Charlie Frye, Esri Chief Cartographer

Maplex Label Engine's Street Placement Option

You may already have the Maplex for ArcGIS Extension. It’s free with an ArcInfo license of ArcGIS. Many ArcInfo users don’t know this and that fact has unfortunately kept many people from taking advantage of the superior text placement capabilities in the Maplex Label Engine.

One of those capabilities is the Street Placement option, it is available for line layers. Though it is obviously for street labeling, we are often asked what exactly does it do? Here’s the answer. Continue reading

Suggested workflow for creating hillshades

By Charlie Frye, Esri Chief Cartographer

Thumbnail

A few months ago I wrote a blog entry called setting the Z Factor parameter correctly, and I used the Hillshade tool as the example. Since then several people wrote into Ask a Cartographer with questions related to using the Hillshade tool, and we’ve responded additional guidelines that are worth sharing more broadly. Together, these guidelines form the basis our standard workflow in producing hillshade datasets.

Creating a legend for hypsometrically tinted shaded relief

By Charlie Frye, Esri Chief Cartographer

Example of a shaded relief image

Here’s a question that has, in various forms, been posed on Ask a Cartographer:  “I have a map that has a hillshade and a DEM drawn with transparency on top of it. I cannot figure out how to make a legend that properly shows the final colors on my map; how is this done?” Continue reading
