Hi Michael,
I'm more concerned with subjective metrics, I actually plan to survey
some users. The questionnaire will include some map samples and gather
user preference for each criteria. My problem is to identify what
questions/criteria should I ask to a user.

Is your idea to measure the quality by having a human look at outputs
(subjective metrics) or automatically via some analysis routine (objective
metrics)?

Subject: [OSGeo-Discuss] How to assess rendering quality?
Hi list,
I'm doing a comparative study of OpenSource cartographic servers
(Mapserver, Geoserver and Mapnik). Beside raw performance and
features,
I'd like to assess the rendering quality, say how pretty
produced maps
are. Precisely, I'm interested in the quality of the drawing work, my
point is not about symbology, nor styling of maps.
I have some problems to find a set of objective criteria I could
benchmark my servers against. So far, I have already identified the
following:
- sharpness of details
- smoothness of lines
- uniformity of colors
I'm open to any comments. Do you think these criteria are consistent
regarding the purpose of my study? Does anyone have other criteria to
suggest?
Regards
