What is an overlay?
|
 |
|
An overlay is an image file placed on top of an aerial image that provides the user with data about the image. This can include road names, flood plains, schools, parcels, earthquake zones, landslide zones, parks, hospitals, airports, and governmental information (zip code, city name, county lines, etc).

|
Where do you get the data for your overlays?
|
|
|
Data for our overlays comes from various government sources. Flood data and other natural disaster data comes from the Federal Emergency Management Agency (FEMA).

|
How reliable is the data in the overlays?
|
|
|
While the data in the overlays is relatively reliable, we do not guarantee its accuracy. They are a good starting point but they will not replace research when precision and accuracy are important.

|
|
Can I print or download an overlay?
|
|
|
Currently, you cannot print or download an overlay. They are simply a reference for online viewing.

|
Why aren’t overlays viewable at certain locations?
|
|
|
Road and location overlays should be available throughout the United States. Parcel data is only available in certain areas where the information was stored electronically and made available to our suppliers. FEMA information should be available for most locations though there are areas where the information is not. Currently, FEMA provides flood data for just over 1,250 counties in the United States. We provide all of the data that we receive to the user.

Why aren’t overlays viewable at certain zoom levels?
|
|
|
Certain overlays are not conducive to certain zoom levels. For example, neighborhood streets would overwhelm the viewer when you are viewing an entire city. Most overlays are viewable when zoomed in below 8 meters and above 1 meter. If you cannot see a specific overlay, you may be zoomed out too far or in too close. If you still cannot see the overlay, it may not be available or applicable in your area.
