I am working on a hydrologic model but I only have access to gridded rainfall data, how can I use it to develop a meteorogical model?

I am using ArcGIS Desktop 10.3 and HEC-HMS 10.4.1 and TRMM data. It was in NETCDF format but I converted it into raster.

  • Welcome on GIS SE. Does gridded mean raster? I'm not into HEC-HMS, but I'm sure it would be helpful to edit and add some more information to your question. See how to ask good questions. – MrXsquared Dec 16 '18 at 3:29
  • By "gridded" do you mean a point file at a specific interval? IE a Minute by Minute grid of rainfall for an area? If this is the case, you will need to rasterise the point file using one of the interpolation geoprocessing tools in Spatial or 3D Analyst. Topo to Raster and Kriging may be good starting points. – Keagan Allan Dec 16 '18 at 23:40
  • Hi shafik. Two things: you added an answer with supplementary info on your question; however, you should edit (button below the question) your question instead, adding any information needed or requested! I have done this for now, and recommended your answer to be deleted. then, it seems you have two accounts? that is unnecessary, you should either delete one or merge them. – ThingumaBob Dec 17 '18 at 9:36
  • You appear to have created two accounts which inevitably leads to a frustrating experience for you, potential answerers and reviewers so please follow these instructions ASAP to merge your accounts. – PolyGeo Dec 17 '18 at 10:13
