I’ve experienced similar challenges, and one thing that stood out was how important it is to use professional digitizing services for converting legacy map data into usable GIS layers. Without proper digitizing services https://gis-jot.com/services/gis-data-conversion-digitization/ scanned paper maps and raster PDFs remain non-editable, which interrupts the workflow. In addition, converting formats from CAD or other GIS file types requires careful feature extraction, geometry cleaning, and attribute validations to prevent data loss. Coordinate system conflicts can be especially tricky, as mismatched CRS data leads to misaligned layers and faulty analyses. I found that relying on specialists who understand these nuances made a big difference in maintaining topology integrity and accurate attribute QA. There’s also the challenge of migrating data between different GIS platforms without breaking schemas, which requires extra attention.
