I then need to convert the resultant file into ascii format. I’ve been trying to do this in Arc using the mosaic function, before I export it to other software to build a ground model and carry out the hydraulic computations that are needed. The problem is that the ascii file I end up with is enormous, around 50X the size that I was expecting. Can anyone please let me know what might be going wrong?</P><P></P><P>Many thanks,</P><P></P><P>Nick</P></BODY></HTML> Fri, 22 Jul 2016 15:01:38 GMT https://community.esri.com/t5/water-resources-questions/lidar-mosaic-question/m-p/439141#M3933 NicholasBurke 2016-07-22T15:01:38Z Re: LiDAR mosaic question https://community.esri.com/t5/water-resources-questions/lidar-mosaic-question/m-p/439142#M3934 <HTML><HEAD></HEAD><BODY><P>ascii files will be larger than their binary equivalent, nothing is wrong.&nbsp; What other formats does the destination software support?</P></BODY></HTML> Fri, 22 Jul 2016 15:03:49 GMT https://community.esri.com/t5/water-resources-questions/lidar-mosaic-question/m-p/439142#M3934 DanPatterson_Retired 2016-07-22T15:03:49Z Re: LiDAR mosaic question https://community.esri.com/t5/water-resources-questions/lidar-mosaic-question/m-p/439143#M3935 <HTML><HEAD></HEAD><BODY><P><BR />Hi Dan, thanks for getting in touch.
