Marilyn That location, for that time of year, will only receive circa 6*149=894 minutes of sunshine. If start time = 0 and end time = 24, then t0 will be sun rise and t1 will be sunrise + 6 minutes.   Regards -Steve     ... View more

Matthew I'd be cautious of smoothing the contour lines (i.e the output). We rather recommend smoothing the input raster as explained in the Contour documentation.  Or, you could delete the short contours as Dan Patterson‌ suggests. -Steve ... View more

max vertices will not change the output. All it does is split a line with many vertices into many lines. ... View more

...and the 10m and 30m rasters have the same spatial reference and I guess the one has a cell size of 10 and the other has cell size = 30? ... View more

The output raster type (integer or float) is dictated by the input field type, in your case  HYDGRP_NUM. What is the size of the output raster, i.e. how many rows and columns does it have? ... View more

No, it'll be fixed in 2.7. BTW, another work around, if you change your output from fgdb to .tif it works as expected. ... View more

...if your mask is a point feature class, then the output raster will only have values that coincide with the point locations (from the mask). That is why the legend had correct values. Likewise for polylines. ... View more

your groundwater levels can be converted to height above mean sea-level or depth below the well casing (negative amounts) and these values will be used in the interpolation. ... View more

Jay We need some additional info, please - what version of ArcGIS? - what does different mean, maybe a difference raster (between with boundary and without boundary)? - did you keep the cell size the same between with boundary and without boundary interpolation? - what are your TopoToRaster parameters? - screen shot of your input data including the boundary outline - what is you ultimate goal with this exercise? -Steve ...

In that case you could use IDW in Geostatistical Analyst to create a ga layer and then use GALayerToPoints which will use the interpolation parameters in the ga layer to predict a value at exactly the given locations. The ga layer, does no have a cell size, and is held in memory. You could also then do cross validation on your method. ... View more

What about IDW to raster followed by ExtractValuesToPoints ... View more

Allen - What version or ArcGIS? - When did it stop working? - What type of input features, are then points in a shapefile, a file geodatabase or ? - Do you accept all the default parameters? - What happens if you use Copy Features tool to make a copy of these points features? - if Copy Features succeeds, does IDW succeed using the copied features? - Did the reboot help?  -Steve ...
