General Information

The Scientific Assembly of the International Association of Geodesy (IAG97) will be held from 3 to 9 September, 1997, in Riocentro - Rio de Janeiro, in conjunction with the XVIII Brazilian Congress of Cartography (XVIII CBC) under the organization of the International Association of Geodesy and the Brazilian Society of Cartography, Geodesy, Photogrammetry and Remote Sensing (SBC).

The weather in Rio de Janeiro is never very cold, even during the winter. The lowest temperatures in the city are beetween 10 - 15 Celsius and happen in general in July. In September the temperature oscilates beetween 25 - 30 Celsius. Rain at this time is very scarce but can happens in short periods of time during the day.

IAG Executive Committee took a few decisions in the meeting in Potsdam - April 1997:

-to not organize paralel sessions during the assembly

-to give a special importance to poster sessions in the meeting

You are welcome to attend IAG97/XVIII CBC and LOC will do the best to make your stay in Rio de janeiro very agreable.
