As far as I can tell, these tags are functionally identical.
I've taken a mix of questions from each tag and jumbled them into a list.
Can you guess which question has which tag?
- How can I sucessfully import 3D surface and features from ArcGIS 10 into Sketchup 8?
- How to import/export geographic information (gml or csv file) to geodatabase?
- How to batch import GDAL supported raster files into GRASS?
- What tools are available for uploading gis data to a database?
- How to best prepare CSV files for use in ArcGIS?
- How to convert KML to shapefile without losing attributes?
Can we merge the [import] tag into the [data-import] tag?
I feel that favoring the [data-import] tag is more descriptive.
UPDATE: It's been done, community opinion was clear and the tags have been merged (so no need to vote anymore :)
