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
