I have noticed that the aerial imagery for my area is outdated, possibly about three years old in some spots. in instances where a new building exists, replacing an old one, in the cases of grade schools, I am relying on both personal knowledge of the area, and Google Earth's imagery which is only two months old for some areas. Is there a way to obtain better, more current imagery for my area? Or is it just a matter of waiting for it to show up? |

Good question. The base layers (look in upper right corner, and click on "Background" to see available layers on navigator.er.usgs.gov) used for TNMCorps include NAIP (1 meter resolution) which is usually updated on a three year cycle, and Aerial Imagery (TNM) which includes some higher resolution imagery over some metro areas. It is usually a good idea to toggle between the two when looking for the most current imagery. There is no problem using Google or Bing as an additional resource (but not as the primary authoritative source) when trying to make sure you place the point correctly. Many editors keep several browser tabs open when editing. |
