How to import a MapInfo TAB dataset

Import a MapInfo TAB dataset by uploading its four files together: .tab, .dat, .id, and .map. Convert .mid and .mif files first.

A MapInfo TAB dataset uses four loose files: .tab, .dat, .id, and .map. Upload them together. MangoMap does not accept .mid/.mif. Convert those files to TAB or shapefile first.

Before you start

You need an account role of Admin or above to import data.
Your MapInfo dataset must include all four files: .tab (definition), .dat (attributes), .id (index), and .map (geometry).
Each file must be 5 GB or smaller.

Open the import page

From the Data page, click Import data. Or, from a map, open Manage layers and click Import new data to import directly into that map.

Pick the format

In the Data format dropdown, select Tab.

Click Upload files and select all four files together, or drag them onto the page. MangoMap matches each file to its row by extension and uploads it in the background. Wait until every progress bar is full and green.

If a row shows File missing, click the Upload button on that row to add the missing file.

Name the dataset and save

When all four files are in, the name fields appear.

Enter a Dataset name. It is required, and MangoMap fills it in from the file name.
Optionally add a Description.

Click Save. A Processing data… dialog appears while MangoMap reads the dataset. When processing finishes, you land on the dataset detail page (or back on the map).

If your dataset has more than four files

MapInfo can produce additional files such as .ind (attribute index) and .mid/.mif (Interchange Format). Leave out any extra files, such as .ind.

If you have a .mid/.mif pair instead of a TAB set, convert to TAB or shapefile in MapInfo or QGIS first.

Troubleshooting

“File missing” never goes away on one of the rows. That extension hasn’t been uploaded. Check that the filename ends in the right extension — operating systems sometimes hide extensions.

Processing fails with Unsupported coordinate system. The TAB file declares a projection MangoMap can’t reproject from. Reproject to EPSG:4326 or EPSG:3857 first. See Unsupported coordinate system.
