Create a Model

[DilipWagh]

Hi All,

I need some help to make a model, which will become a geoprocess in Server.

Basically I need to calculate population stats from a point coverage, where each point has the number of people as a value in the 'population' field.

1. I need to draw a polygon on the map which selects all points 'Within' - I have done this

2. Once the selection is made I need to calculate the sum of the values and return that value as the total population in the Area drawn. - This is what I am struggling with

A pretty simple model I am sure, but I have not used Model Maker for a long time as I use FME, and trying to find the tools if problematic, I hope someone out there can assist.

Many thanks in advance.

Regards

After selection use summary statistics tool which will calculate sum and return the sum in a table.

ArcGIS Help (10.2, 10.2.1, and 10.2.2)

Further you can use Get Value tool (model only tool) to use this value in next analysis.

Hope this is helpful

Dilip,

Doesn't the Chart Widget have this functionality straight out of the box?
