Inserting IHO/INT1 Compass Rose

JustinOdell — Thu, 21 Oct 2021 00:46:15 GMT

Hi all,

I wish to insert an 'IHO / INT1' standard compass rose into an ArcGIS Pro layout.

I have the 'Maritime' licensing extension turned on. When I go to insert > north arrow and do a search for "rose" or "compass", I do not see any IHO or INT1 looking compass rose options.

What is the best way to configure an official hydrographic chart compass rose in ArcGIS Pro?

@JustinOdell

I have published a "How To" document to accomplish this very thing! I shared it with you in the attachment.

Hi Justin,

Since you have the maritime extension, you should be able to use the attached stylx with a maritime geodatabase. You need to insert a feature into TidesAndVarirationsP, under the MAGVAR subtype.

You can calculate magnetic variation and annual change using the Calculate Magnetic Components tool https://pro.arcgis.com/en/pro-app/latest/tool-reference/topographic-production/calculate-magnetic-components.htm

Use the option to Connect Symbol Properties to Attributes to apply the geographic rotation (not graphic) of the arrow. https://pro.arcgis.com/en/pro-app/latest/help/mapping/layer-properties/attribute-driven-symbology.htm#ESRI_SECTION1_5E319812B4E14CEBAE02E002305EB0EA

Let me know if you have more questions.

I came across this forum today - but solved this from a slightly different approach. - This places the compass rose on the the map in its location - rather than a layout element

In the ArcGIS Maritime Server Install files there is a directory

C:\Program Files\ArcGIS\MaritimeServer\Server12.0\customchartbuilder\CompassRose

A Filegeodatabase and a lyrx file

Make a copy of this directory and you can paste this to your working project

Add the lyrx file to the map

If necessary point the source data to the compass rose feature in the file geodatabase

Now you can add points in the location(s) you desire - save your edits

Now you can use the tool Calculate Magnetic Components

and map the fields to the Value of Annual Change in magnetic variation and the Value of magnetic variation.

(Or if you know these values - you can populate these in the attribute table manually - you will still then need to save your edits after this)

Either method will change the rose as shown here. (image(15).png)
