Need a "nearest" capability when doing an Extract To Values

LaurieKurilla1

I am using continental environmental raster data which does not align tightly with the continental boundaries.  For much of my work this is not a problem.  However, I have a set of point data (landslide events) and I want to extract values from the environmental rasters to these event points.  However, the event points are designated accurately with lat/long  and the problem therefore arises at the coast and a few other internal areas - where the raster data does not fit.  I need the equivalent of a "near" function with the Extract to say ... either extract the raster value that the point sits on or the nearest raster value.

When I encounter this problem for a few dozen points, I manually update the data.  However, because I am working at the global level I have 1668 points that need this 'near' capability.  

Is there anything that will resolve this issue?

All ideas appreciated 🙂

Thank you

I found a solution from a 6.20.2020 reply by Robert LeClair to a problem post similar to mine:

1. Run the Raster to Point geoprocessing tool first to create a point feature class with the VALUE you wish to extract from the raster to the point attribute table.
2. Then run the Spatial Join geoprocessing tool with the CLOSEST match_option parameter.  The target_features is your current point feature class and join_features is your output feature class from Step 1.

 

I used this procedure and it worked beautifully.  Thank you to everyone who attempted to resolve my problem.  It is MUCH appreciated.  I learned a few new things along the way.

Cheers
