Hello, I am a surveyor working in both grid and surface ORD Files. I love the background bing map, and it is coming up perfectly in a grid drawing. When I adjust the coordinate system applying a Helmert Transformation and add a scale factor like 1.00013. the background map stays in grid. Am i missing a way of scaling the background map up with our surface coordinates. See the below photo of a bridge and ROW as a visual.
Thank you,
Hi, you may want to try attaching the Bing map as a raster rather than using the background map. I like doing this in a separate file so I can attach it as a reference and clip it to the project limits. It'll appear in the correct location when a Helmert Transformation from grid to ground is applied to the coordinate system.
