I'm working on creating a large number of flight routes, constrained by ETOPS. I've been using the Cost Connectivity tool using costs rasters that represent the ETOPS constraints. I then run the resulting routes through the Geodetic Densify tool, which works great for routes with mid-line vertices that indicate flight path changes. However,… (Show more)

When I look at examples of other trail maps produced in this projection, the meridians, parallels and UTM grids are all perfectly parallel or perpendicular to the data frame. That is not the case when I use this projection. The parallels, meridians, and… (Show more)

It is a common map saved to a folder on the sever.  Today when they opened the map (on various computers) they noticed that items… (Show more)
