3D elevation data fix

← Back to Help

If you use 3D elevation data with OziExplorer and oziTarget, you may have noticed the elevation download feature in OziExplorer is broken. This is outside oziTarget's control — OziExplorer isn't our software — and the author hasn't fixed it despite several requests.

Failed downloads can also crash OziExplorer: the corrupted zip files produce corrupted .hgt files, which can cause crashes on shutdown and delays when opening maps.

Remove corrupted data

  1. Navigate to the elevation data folder, e.g. C:\OziExplorer\Elevation Data\Globe\…
  2. Delete any .ZIP files, and any .HGT files under 200 KB (a healthy tile is around 2 MB).

Get new data

You can manually download 3-arc-second .HGT tiles (about 90 m resolution) from the Viewfinder Panoramas interactive map. (Their 1-arc-second coverage is incomplete but may cover your area.) Find your rough location on the world map, download the tiles, unzip, and copy them into C:\OziExplorer\Elevation Data\Globe\. You can dump them all together or organise into sub-folders. Finally, set the path in OziExplorer under 3D/Elevation → Elevation configuration.

For complete 1-arc-second (30 m) coverage, sign up for NASA Earthdata and use the SRTM 30m tile downloader.
