best approach to calculate cumulative precipitation

Discussion created by aafgilbert01 on Feb 28, 2013

I am setting a weather forecast application and the weather forecast is stored in a mosaic dataset that has a datetime column. I have a forecast for 6 days on a 24 hours time step. This mosaic dataset is stored in a file geodatabase. I am thinking about calculating cumulative forecast for 48 hours and I would like to have an advice on the best approch to do this.

I am thinking about setting a geoprocessing package in ArcMap that will read the layer and calculate the sum of precipitation for 2 days (48 hours). Once this gpk is done, I will call it from my ArcGis Runtime app. When I will be in my ArcGis app, I will make a user interface that will allow the user to select the forecast layer and my function will create another layer that will contain the 48 hours sum of the previous forecast.

Is this the better way to go.
