[gpl_list] Aerial Photo web services

[Dorothy Mortenson]

FYI:

Here are some examples of being able to zoom in with the aerial photos. It would be wonderful if the ESRI service would allow one or two more zoom levels in the rural areas. If there are any other web services I should be aware of (using projection 102100), please let me know.

ESRI image service:

http://services.arcgisonline.com/ArcGIS/rest/services/World_Imagery/MapServer

In urban areas, we can zoom in closer. In rural areas, we cannot zoom to the same scale as urban areas.
Roughly:
1.2" = 100 ft in urban areas
1.5" = 500 ft in rural areas

This is the esri web service as far as it can zoom in a rural area (near La Grande):

For GEO, we can zoom to whatever scale we need, but the quality is very poor.

This is the same area and zoom using the GEO 2009 imagery (in projection 102100). It's not even recognizable.
