I am toying with the idea of compartmentalisation with my map services. The idea is to create separate map services for layers that are thematically or categorically related, i.e. admin boundaries, public open spaces, or emergency planning etc. I would then combine these separate map services in Apps for the end users. This would provide consistent symbology, grouping and data across all my apps and make it easier to maintain. Publish it once, reuse many times.
My question is, is this possible and if not, what are the alternatives?
