What is the relation of the IGS network to regional networks like EUREF, SCIGN, CORS, etc?
These are dense regional networks composed of stations that in most cases meet the IGS Site Guidelines. They are considered to be related networks and the IGS works closely with the agencies which operate them. Typically, a subset of a regional network’s stations is designated also as IGS stations. The choice of which stations should also be IGS stations is motivated by their benefit to the IGS products, according to location and instrumentation.
