1.) Are drones the only mechanism that the city has thought about as an alternative way to collect information from the field? What are some other methods that have been thought about?
2.) What is the city's not-to-exceed budget on this project?
1. No this is not limited to drones. The belief is that survey grade data collection at every asset is time consuming and expensive. The thinking was that Drone or other LiDAR based methods, steps, could gain survey grade data at the surface more cost effectively, allowing assets to then be “opened up” with accurate measurements taken at surface and tied back to that drone based survey or other survey grade surface data.
Various pathways likely require GIS schemas for data collection by asset types: Manholes, Catch Basins, Junction Boxes etc. These schemas may need aspect, depth to inverts, pipe diameters, RCB data, MH inverts. Inlets have their own similar yet different SHEMA based needs to connect it all together. Locations and aspect for connections along with such information. The exact schema for this are not fully known. This method is point based and does not directly inspect lines or get into systems. The SHEMA data would come back to GIS tied to Unit ID data, but relocated to geospatially correct surface locations. Connectivity needs would then exist between nodes. KCMO has done much CCTV video work, but this work was often tied to a Manhole Unit ID only with pdf’s of data per linear foot into the pipeline/rcb systems, but no real geospatial LiDAR or x,y,z is collected.
2. We anticipate a not to exceed of $50K for the purpose of the program, but because we have not done this before we don’t want to limit the potential solution. We request you make case for your suggested budget per the application. We are open to starting with a pilot area to demonstrate the solution and potential savings to the City to justify real costs of complete program solution.
