Hello, Kevin: I've been trying to make sense of the scale values provided by gvSIG when using feet as the map unit, and have also experienced a strange behavior. The scale seems to work fine in the view, but when creating a map (layout) with it, it does not make sense for me either.
In case somebody wants to test it, here is a WMS service that uses feet as the map unit: http://gis1.oit.ohio.gov/wmsconnector/com.esri.wms.Esrimap/osip? The true length of the building seen in this image is about 110 meters: http://gis1.oit.ohio.gov/wmsconnector/com.esri.wms.Esrimap/osip?REQUEST=GetMap&SERVICE=WMS&VERSION=1.1.1&LAYERS=50&SRS=EPSG:102723&BBOX=2481555.9699062333,1124765.0365067134,2482132.8341791052,1125240.8262702362&WIDTH=469&HEIGHT=387&FORMAT=image/jpeg&STYLES=&TRANSPARENT=TRUE but when creating a map (for example using A4 page size) the scale does not show a sensible value. As for the SRS, the server calls it EPSG:102723 but it's actually ESRI:102723.

Summary: The scale in the map function does match the actual scale. using version 1.10 I insert view. At the properties dialog the scale (1: 4000) appears to be incorrect for the view. Setting the scale to the a known view scale from the prior view menu results in a very different view. The measurement of the known feature indicates 400 feet as compared to 50 feet using an inserted scale bar. I have altered the projection to see if it makes a differance. It appears that I may be missing some very simple setting that I have not found, or maybe some type of bug? The rest of the program functions great. Thanks, Kevin
