comment What WMS server would be suited for serving many aerial photos?
gdal.org/gdal_utilities.html - it´s all here! Here you can basically do 99% of all your raster work and preparation for geoserver. geoserver.geo-solutions.it/edu/en/raster_data/… also shows the image pyramid workflow. Join and search the mailing lists for further assistance

comment what is the relevance of cosine in determining map resolution?
- ok so it´s simply the ratio used to calculate the length of the distance from 0° Longitude to the tangent of the sphere, thus giving the resolution at the given latitude.

comment Why are map scales not used instead of Zoom-levels in web mapping clients such as OSM or Google Maps?
...although for a certain point on the sphere, the resolution can be calculated - but to calculate distance between 2 points (i.e line length) or area of a polygon I would be calculating distances or areas using different scales for each pixel - which is obviously madness.

msdn.microsoft.com/en-us/library/aa940990.aspx This link perfectly explains the spherical mercator and problems associated with it
