Good evening, I use opencitiemaps and I should import cadastral data in csv format, these data will have to be linked to the map on opencitie with a symbol or a number, my question is if there is this possibility to do it via geospacial or other ways to connect things. Would you give me a guide. thanks
thanks, I'll try your method and update you on the evolution
In the Map Manager you can create a join between a layer and a CSV file. In the Define Joins dialog, create a Session Feature from the CSV file using the option New File Source ... As Jan already mentioned, there should be a join column between the imported CSV file and the CSV file with the attributes.

Thanks Jan, for your time, I wanted to know if it was possible to create a features, with line and circle and number to be inserted at my choice like the example I have attached. Thanks again
Hi Christian,
thanks for the files. It's not clear how they can be joined (linked) together, because I do not see any unique ID. What columns should be used as "link"? Or is it organized in such way that a row is equal to row in 1:1 relation?
I quickly check VRT format description and I still think that it's not possible to define relationships between different data sources. And even when it would be possible (maybe some "VRT expert" will find a solution), I am not sure whether it will be the right way.
I recommend to process CSV files upfront, which allow to check data quality and to filter and reorganize data to obtain required data format. To link and join CSV files can be done in many ways, you can find plenty of discussions on internet, from simple command line approach over Excel to specialized tools. I think e.g. csvkit is simple but powerful tool.
With regards,
Jan

The image is the result of my work as a designer of expropriations on autoca that I would like to import into Opencitiemaps. Once the points have been entered I would like to create a feutors that automatically creates the circled numbers for me.
