I'm trying to merged several shapefiles (about 700 waypoints) together at one time via model builder and I keep getting variable outcomes. Sometimes the merged file will only have 3/9 shapefiles on the final products whereas other times it might have 6/9. My apologies for the dumb question but I really can't see what I'm doing wrong here.
To give some (possibly) correlated information, the shapefiles that aren't appearing on the final merged file is reported by arcmap to not have spatial reference information, even though they show up in the right place before merging anyways. Additionally, sometimes the layers that are reported to not have spatial reference information do show up in the merged file.
