hi every one,I'm trying to extrapolation my spatial data to larger area, but I don't know if its possible and which tool can.
I m working with pollution concentrations ,its follow a specific spatial trend
thanks
Here are a few solutions listed:

You cannot set the extent larger than that of the input points with EBKRegressionPrediction. The other interpolation tools (except NaturalNeighbor) can be used for extrapolation.
However, be warned. It is a bad idea to extrapolate.
yes I m trying to extent this to larger area but I coudnt do it in arcgis pro like I use to do in arcmap
Yes I m sure that there is a trend it been demonstrate by prior studies in the field.
Set your analysis extent to the larger extent prior to running the tool. In any event, extrapolation is generally a bad idea unless you are absolutely sure that trends seen at the edges persist beyond the margins
yes I have access to Geostatistical analysit extension,I have pollutant concentration of an area and I apply the EBK Regression Prediction method from Geostatistical wizard in Arcgis PRO using altitude raster as prediction variables.for the area i got very pretty result but I wanna to extrapolate for larger area.
the current extent of the data
top :50.856194
bottom:50.767833
left:15.151972
right:15.357413 dd
and I like to extrapolate to
top :51
bottom:50.7
left:15.10
right:15.4
please note that I tried the extent tool but it s not activated in arcgis pro
Can you elaborate a little more on what type of data you have, the current extent of the data and how far you would like to extrapolate the data? Also do you have acces to the Geostatistical Analyst extension?
