Aerial Photo Dates Layer: A Helpful Tip for Getting the Most of ISU Orthoserver
The Iowa Orthoserver (also known as the Iowa Geographic Map Server) has a variety of resources available to enhance and serve users. Today we are highlighting the Aerial Photo Dates layer. This layer allows users to determine the date of a particular image.
Here are the basic steps to using the Aerial Photo Dates layer in the Iowa Geographic Map Server ArcGIS Web App:
- Open the Iowa Geographic Map Server ArcGIS Web App.
- Select the first icon – Choose Map Layers (looks like 3 stacked sheets of paper.)
- Scroll down to the Iowa – Aerial Photo Dates layer and then check the box to turn it on.
- Expand the menu by clicking the tiny gray arrow to the left of the check box.
- Now turn on whichever year of flight date you wish to use (the orange areas symbolize the flight paths and within them will appear the flight dates.)
- *Please note* for some of the older imagery years (example 1930s, 1950s, etc.), you need to be zoomed in for the flight dates to appear. Zoom into an area of interest, the flight patterns and dates will be shown.
The statewide 2021 NAIP flight date layer is not yet available. This will be released when the layer is available. If you would like information regarding specific areas for the 2021 flight, please contact Amy Logan.
