ArcHydro in ArcGIS 10; error running longest flow path function. Help!!

AnneWynn

I keep getting this error message when I try to run the longest flow path tool using the newest ArcHydro extension in ArcGIS 10:

WARNING 010353: The environmental cell size is ignored
What does this mean??

I was able to make this tool work in ArcGIS 9.3!

Someone please help me!!!

Tenia el mismo error 010353 y pude solucionarlo proyectando nuevamente los archivos de entrada raster y vectorial) en un mismo sistema de coordenadas.

(1) WARNING 010353: The environmental cell size is ignored.
please check on: http://help.arcgis.com/EN/arcgisdesktop/10.0/help/index.html#//00vq00000005010353.htm
(2) at ESRI.ArcGIS.Geometry.ITopologicalOperator.Intersect(IGeometry other, esriGeometryDimension resultDimension)
the data you used for this operation could be coming from data of different projections/spatial-references.

I am running GeoHMS (version 10.1.0.42) on ArcGIS 10.1, and got same error message while running the Longest Flow Path. The error message is listed below:

If anyone has a solution, please post it here. Thanks.

With latest Geo-HMS build up, one can run the Longest Flow Path funtion on a selected set of streams at once. Thanks to the software development team for making this new option available.

I am also having this error. Does anyone know how to fix it?

Hey Anne,

Were you ever able to resolve this? I'm getting the same error message when I try to run Longest Flow Path tools, using ArcGIS 10.1, and the latest version of ArcHydro.

Thanks,
Brendan

I am going to have to reinstall ArcMap 9.3 in order to get ArcHydro tools to work properly. Wish these tools were more user friendly and also that the ArcHydro support was more helpful.
