I'm doing a similar thing with Google Earth pins. As a geotechnical engineer, I'm doing a lot more projects that are each on a smaller scale than some other types of civil engineers.My pro tip for this - use Excel for the data entry part. Once you have a set of data, then use an online Excel to KML converter to send this database into a map. Using this method does several things:
I'd also suggest only sharing screenshots of this map if you are changing companies or using this in a customer-facing way. If somebody has the full KMZ, they could theoretically say, "Oh geez, you worked on Aunt Margaret's house?" or parse the data to say "You had a master contract with that restaurant chain?" And be careful with the zoom - I only with zoom in as far as a city-wide or suburb-wide level when sharing to protect the underlying data.Hopefully this is helpful for everybody!
