Calculate field based on filtered points layer

RileyScanlan — Mon, 10 Feb 2025 17:10:04 GMT

Hi there,

I am trying to pull a text field from a points layer that meets two filter criteria. I have a very similar calculation that works in another field but can't get this to work. I think it's something related to trying to pull one value from a whole featureset? But not sure what the solution is.

Thanks in advance!

// set the point feature layer as a variable

var tree = FeatureSetById($map, "18d5b66cd4a-layer-17")

var filter_by_grid = "'" + $feature["GRID_ID"] + "'"

var filter_by_year = "'" + $feature.PROJECT_YEAR + "'"

// the filter expression

var filter_expression_grid = "GRID_ID = " + filter_by_grid

var filter_expression_year = "PROJECT = " + filter_by_year

// filter the the points to only this block

var filtered_grid = filter(tree, filter_expression_grid)

var filtered_year = filter(filtered_grid, filter_expression_year)

//var trees = First(filtered_year)

var trees = First(filtered_year)

return trees.Re_Entry
