ZeeMaps enforces an upload limit for uploading geographical location data through spreadsheets. The upload limit is such that after a spreadsheet upload, the number of entries on your map cannot exceed your upload limit.
Until recently, our Basic (free) plan allowed up to 500 entries to be uploaded per map. Starting today, due to increased operational costs, the upload limit for Basic plan will be set to 100.
This limit does not apply if your data already contains location information (latitude, longitude), or if you add markers one by one (e.g., through crowd source).
Please let us know if you need some time to adjust to this change.
