Disagreements when applying Google Street View to decode aerial data
It's nothing, it happens to everyone! 🙂 You are confused because Google Maps and Google Street View are different things.
Google Maps is a mapping service providing interactive maps, satellite imagery, navigation, and information about locations and routes. It allows users to plan routes for walking, driving, public transit, and biking. Google Maps also offers real-time traffic updates and recommends points of interest, restaurants, hotels, and many other places.
Google Street View is a feature within Google Maps that offers panoramic images of streets and locations. It allows users to "walk" through streets and view buildings, roads, and landmarks in a panoramic view. These images are collected using specialized cameras on vehicles, bikes, foot, and even drones for hard-to-reach places.
If you, for example, made an aerial survey and passed it for 2D and 3D planimetric mapping (decoding) to another person who was not physically present at the site, do you think he will have difficulties? 🙂 I worked for a total of 9 or 10 years, sorry I have lost count of the topographic engineer and always did field sketch. On very large projects such as topographic surveying town, we even had separate survey parties driving around the streets to record video and take note of the directions of wires, types of fences, utility elements (pipes, transformers) so that in case of a mistake there was a visual source of information to check.
A little advice: if you are doing an aerial survey and plan to pass it to another engineer for decoding, spend 10-15 minutes of your time and record video at the site. It may not cover the whole site, but in case of disputable issues during decoding aerial data, this video will make the work for the project executor very easy.
Thx
I use Google Street View when pricing a new job all the time. Gives a good perspective of the site. Best story; looking at a lot for a boundary survey and what shows up on the adjoining property, stakes and flagging from a recent survey! I was like, wow maybe we can make a buck on this one! LOL
"I am at a loss trying to figure out how anybody would possibly be using digital imagery from Google Maps or any other similar imagery providers."<div>
I don't think the OP is talking about mapping directly from Google et al. He is talking about using it a collateral information. It is no different than looking at site photos to clarify information collected in the field.

It's much different when it comes tracing digital imager, right down to gutter lines and showing them on a plan with offsets without understanding the coordinate systems involved, especially on an international level.
I have some experience of working in different coordinate systems, including the British (or Imperial) System of measurement; of course, I may not know something, we all learn new things from time to time.
For example, in Europe, in Belgium in particular, surveyors work in Belge 1972/ Belgian Lambert 72 (31370), but, including, they use the old coordinate system Belgian Lambert 2008 (3812). In Israel, it is Israeli Geodetic Datum 1995, IGD95, and all geodetic work is performed in Metric System of measurements.
In the U.S., it is, quote:
“Coordinate values should be based on National datums. Horizontal coordinate values should preferably be referenced to the North American Datum of 1983 (NAD 83). Vertical coordinate values should preferably be referenced to the North American Vertical Datum of 1988 (NAVD 88). However, it is recognized that many legacy maps and geospatial data are referenced to older national datums, such as the North American Datum of 1927 (NAD 27) and the National Geodetic Vertical Datum of 1929 (NGVD 29).”
If it is fundamental for you, Google Maps, OpenStreetMap, Bing Maps are based on EPSG:3857, Spherical Mercator. At one time, I even conducted a study for myself on how and with what accuracy qGIS performs transformation of Google Maps images from EPSG:3857 to EPSG:2272 - NAD83 / Pennsylvania South (ftUS).
If I understood you correctly and you meant road drainage, I am quite familiar with the United States Road Network. The “with offsets” thing I didn't really understand.
In the context of my original question, I quote, “Maybe there are specific statutes, administrative rules, and/or ordinances that regulate this scenario?” do you have any insights?
