Hi Neil, I have been trying to do this following your guidelines but to no avail. Should I do this directly in Catalog or should it be through the toolbox i.e. either Project or Define Projection? If there are guidelines online that you know and could refer to that would be great. Thanks again! Francois

Thanks a lot Neil! This is really useful and I believe this is the correct answer. Indeed moving SHP around in editing mode is neither scientific nor time efficient. I will look more into this datum issue as I have a lot of SHP in my library that display similar issues. Interesting how colonial history is helping understand current GIS issues!

just editing and moving the SHP manually worked alright actually!

I have done the same with another SHP i.e. add SHP first then added basemap. Much better results ie only 40 meters mismatch (see below, blue SHP is still 400 meters off but new (red) SHP is much closer to the river). So it looks like my first SHP is not of very good quality... Now the question is what can I do to move my original SHP 400 meters? This is I guess where my GIS skills are too limited but I would like to learn!

Hi Kishor, I tried that but still no luck. I have attached the SHP for your info (actually WGS_1984_UTM_Zone_47N). Thanks! Francois

Hello all, I have been looking for answers, from coordinate systems issues to projection issues but have not found a solution to this sticky one yet. As you can see below, my river SHP does not match the river on the satellite imagery... only by... 400 meters. Coordinate systems and projections are the same (I projected the river shapefile (was WGS84UTMzone47N) to the projection of the imagery. Would anyone have a clue what the problem is? Thanks! GGN406
