In today’s tool, we look at how to perform a Location Query.
Why is this important, let me give you an example…
When laying out proposed geometry within an existing wooded site, it is important to be able to quickly determine how many trees will be impacted as a result of the improvements. In other words, existing trees within 50’ of either side of the road centerline could be negatively impacted during road construction and restoration. (Especially if there is significant earthwork cuts or fills)
Some of these trees may be desirable, less than desirable or even considered Legacy trees which we can’t touch at all. Knowing this, it is critical to know exactly which trees are being impacted such that that information can be factored into the design as soon as possible.
Thinking about how to accomplish this rapidly uncovers some significant challenges. How do we create a 50’ buffer around an entire road network? Is that even possible? Once we have a representative buffer, how do we use it to isolate things like trees? And once they are isolated, how do we generate a list?
At first, it sounds like something that will take us the better part of the afternoon to accomplish. But as we look deeper into the Geospatial (Map 3D) tools embedded within Civil 3D we find we can complete the task in only a couple of mins.
