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,
You may also want to check out creating a new coordinate system using a projection with an affine processor, then applying your scale factor to A1 and B2. This will align your bing map.
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.
