Hey everyone, I am working with shapefiles which in part contain the same points but I assume due to reprojections in the past or possibly recalculations of geometries with different accuracies, those points drifted apart and i am now left with files that plot like this: Is there any tools availible to identify and correct this drift so I can properly identify the matching points? Sadly the drift is not completely uniform across all points so simply moving all points by x/y is not an option.  Any ideas appreciated. Thanks a lot.   ... View more

Hello everyone, I have a table and a shapefile containing lining up points The Shapefile contains all points in order from 1 to x without any additional metadata kinda like this iD Shape 1 Point 2 Point ... ... X Point   The other table contains infos about the Naming of Profiles which are made up of those points something like this: Name iD from iD to Profile 1 1 50 Profile 2 51 90 ... ... ... Profile Y 23455 23501   I am trying to join those features in a way that I add a column to my shapefile containing the info about the Profile names like so: iD Shape Profile Name 1 Point Profile 1 2 Point Profile 1 ... ... ... 50 Point Profile 1 51 Point Profile 2 ... ... ... 90 Point Profile 2 ... ... ...   I reckon there must be some way to join tables, but having to columns with start and end ID's is throwing me off. Does anyone have an idea? Thank you ... View more

Hi all, i am working with some fairly old maps which contain a grid of sectors which are based off of geographic lat/lon lines. Considering the age I presume those maps were created with some old geodetic datum. My goal is to recreate that grid as a shapefile/feature class. I can create a geographic grid via Layout in arcgis pro in my current project (which uses the UTM 32N/ETRS89 coordinate system (EPSG 4647)) which i presume is then based on the ETRS89 datum, since thats the projects working system. This grid is already fairly close to my old maps.  To create grids in another coordinate system I created different projects with different working coordinate systems and created the grids there and then tried to load these into my project. Here is where I am tripping. All of the grid I created are off by way more (several km) than I anticipated, also these dont correlate at all to the old maps. Even when I created a grid in ETRS89 (EPSG 4258 in this case) it was off by roughly the same amount. I expected at least this one to perfectly overlap with the grid I created in my original file.  Clearly I am making some error I am not considering here. Can someone with a bit more knowledge in projections and transformations give me a hint on how to achieve my original goal? Heres a picture of the difference of my ETRS89 grid created in my working project (black) and the loaded ETRS89 grid from the seperate project: thanks in advance ... View more

I have a feature class containing thousands of lines which gets confusing to look at/work with. So my idea was to create a grid overlaying my map in which I can select any given quadrant and get all lines intersecting only this specific quadrant.  The closest I have come to realise that idea is the select by location tool which is not quite what I was hoping to do. I was wondering if there is a way to click a quadrant and automatically select corresponding lines kind of like relationship classes work, without taking the detour to the selector each time.  Any other tips to visually "declutter" or ways to automatically visualise only a subset of large datasets  would also be much appreciated. Thanks a bunch!     ... View more
