Is there a way to emulate the Data Driven Pages process (ArcGIS 10) of reading angles (rotation) in a polygon shape file? Screen shot of the DDP window with rotation field and corresponding attribute circled in green

In other words, make a polygon rectangle shp recognize an "Angle" field from its attribute table and automatically rotate the polygon rectangle based on that "Angle" field ?

  • How was your Angle field populated? forums.arcgis.com/threads/… – Mapperz♦ Jan 26 '12 at 20:12
  • it's all Esri-automated as far as i can tell with Data Driven Page's "Strip Map Index Features" function (in ArcToolbox > Cartography Tools > ddp)... i usually run this tool based on a long polyline and the attribute table always has the angle field populated in the new mapbook shp file it creates. – sirgeo Jan 26 '12 at 20:45
  • Seems i could better formulated this question, that esri forum "It's much harder than that!" link is not really helping much... i will post question again without using Data Driven Pages as a reference for what i am trying to do, if mods think that is okay? – sirgeo Jan 27 '12 at 13:55
  • FOUND SOLUTION forums.esri.com/Thread.asp?c=93&f=987&t=210244 will need to download EasyCalculat10 here:ian-ko.com/free/EC10/EC10_download.htm – sirgeo Jan 27 '12 at 16:42

The asker of this Question has not logged into the site for 6 months but it looks like he/she was satisfied with the answer found at the ArcGIS Discussion Forums:

You can use the field calculator with "polygon_rotate_byFieldValues.cal" expression of EasyCalculate(http://www.ian-ko.com). It will rotate the polygons with an angle from a field. The rotation point is the centroid of each polygon. You'll need to do some changes (rotation field) in the code.
