Hi Mark, thank you so much for your answer. I work for golf course construction company in Florida. A typical job involves taking a raw piece of land such as farm fields and wooded areas, clearing the land, digging lakes for fill material and building the golf course and surrounding community (roads and houses).
The end goal for this app is something very similar to what you have in the iOS toolkit v100 samples where you can view hidden infrastructure in AR. Only instead of underground pipes, I want to take the CAD drawings that we receive from the engineers, convert the linework to a feature layer with polylines and drape the feature layer over the base map in the "world view" ARScene. This will allow us to see the job site plans (centerlines of roads, property boundaries, etc.) as if it were drawn on the ground in real world scale when looking through the iPad or iPhone camera. I will have the option to use a high precision GNSS receiver, such as the Pix4D viDoc RTK rover for iPhone, but the app will also be able to use the internal gps if needed with less accuracy. I have no plans as of now to take the data offline.
In the future I'm hoping to have an augmented reality app that will not only show the design plans in the real world before construction as begun, but also once construction is finished I want to as-built the job as well. Using the a sub-centimeter RTK GNSS and the iPhones/iPads lidar, the app will have a cross-hair in the middle of the screen showing the gps coordinates and elevation of whatever the cross-hairs are pointed at. There will be a button that when pressed records a point with the coordinates and elevation of the spot where the cross-hairs are. This will be similar to Trimble's SiteVision only instead of buildings, we will be recording drainage pipes that we install and other land and utility features "as-built".
Thank's for your time and I'll keep an eye out for future updates.
