For all of my industrial planning projects, I look to aerial photography as the best way to receive the data I need to plan my spots correctly.

The reason that aerial data is so effective is because contrary to the way the earth is believed to be, the land is constantly changing. Ongoing development makes every area of the earth different at all times. For example, I may look at a previously drawn map and assume that there is a house on the corner of 85^th and Greenwood. But if I actually go to that street, I may find that there is now a business, or perhaps there was a fire the month before and that area is completely barren.

That is why up-to-date aerial mapping is so important. Things change, and the only way to know that these things changed is if you get new data and images done. Also, you can never trust how exact any of the previously drawn maps are, because you were not there when they were taken. The difference in scale in incredibly important, and if the scales are off because the previous company did not do the specifications correctly, then the data is automatically flawed.
