Dear all,
I am working with HecRas since a few days and I have a problem that no users manual can solve. Because it is the very first step in producing an 1D model with HecRas I hope that someone can help me soon.
I set WGS84 (EPSG 3857) (file from esri) as the projection. When I load the map layer and measure the distance it is shorter than it should be.
Does someone have an idea where the problem is?
I am thankful for every advice!
Maria
