Sum polygons if they are within another polygon

AndreasDaim

hey!

attachment:
[ATTACH=CONFIG]19044[/ATTACH]

I need the sum shape_area of the blue and black polygons (feature class

which are within the selected green polyon (feature class A, hollow polygonfilling) written in the polygon A attribute.
I tried a spatial join, but this only worked in the other direction, by joining the attributes from the big polygon A to the "compleytely_within" polygons B. Or is there a possibility to merge this results afterwards, if so how?

best regards
andreas

Try this two-steps approach:
1. Select all blue/black polygons B which are in large green polygon A using Select By Location from Selection menu.
2. Use Summary Statistics tool (Analysis->Statistics->Summary Statistics) to calculate summary area for each type of polygon B with settings:
- Statistics Field: Shape_Area
- Statistics Type: SUM
- Case field: type field - the field based on which you differentiate polygons color.

worked fine thx!
I just used as type field my "capture date" and in fact, that the format is sometimes dd.mm.yy and sometimes with dd.mm.yy + time I got seperated values. Can i drop the time before in my attribute column?

To drop the time: create new column and use this simple expression in Field Calculator with Python parser:
!Erfassungsdatum![:10]
(which takes only first 10 characters)
