topic Slowness WIth Add Surface Information Tool and Big Data in 3D Questions https://community.esri.com/t5/3d-questions/slowness-with-add-surface-information-tool-and-big/m-p/439418#M2627 <HTML><HEAD></HEAD><BODY><P>I have a DEM generated from Lidar (tens of gigabytes in size) even when cropping it down to the minimum required size, which makes it a beast to work with and reducing resolution isn't an option. I am using the Add Surface Information tool to calculate mean Z values for a grid (hundreds of thousands of polygons), and the tool takes days to complete its run even on a fairly robust computer (12 core 3.5 Ghz, 64 Gb RAM, all data is on an SSD drive). Is three a faster/more efficient way to get this done?</P></BODY></HTML> Wed, 30 Jan 2019 15:08:21 GMT DanielWalters 2019-01-30T15:08:21Z Slowness WIth Add Surface Information Tool and Big Data https://community.esri.com/t5/3d-questions/slowness-with-add-surface-information-tool-and-big/m-p/439418#M2627 <HTML><HEAD></HEAD><BODY><P>I have a DEM generated from Lidar (tens of gigabytes in size) even when cropping it down to the minimum required size, which makes it a beast to work with and reducing resolution isn't an option.
