Reproject Table crashes

kbadmin — Tue, 19 May 2026 05:15:39 GMT

Occurrence

I try to reproject coordinates but it hangs then silently crashes. No output file is created.

Solution

This is caused by left over files from a previous version of Discover conflicting with new version. Tor esolve, uninstall both Discover and Mapinfo Pro from the control panel, then re-install the latest version of the Discover bundle installer which you can find here -

How to fix incorrect reprojection of data to/from AGD84

kbadmin — Wed, 25 Feb 2026 02:06:14 GMT

If you're using ArcGIS Pro to reproject data between the GDA94 and AGD84 datums, for example using the "Project" geoprocessing tool, the default transform method is NTv2, but this is not valid for some states of Australia. This can lead to results which are out by hundreds of metres. So, if you're converting data from/to AGD84 that is located in the NSW, Victoria, Tasmania, or the NT, you should select a different transform method, such as one that uses a 7 parameter similarity transform.

Please see appendix B of the GDA Technical Manual for a map showing the coverage of the AGD84 NTv2 file.

How do I reserve licenses for certain users?

kbadmin — Thu, 29 Jan 2026 00:06:12 GMT

If you have a RLM Cloud license either concurrent or named user, you may wish to reserve a license seat to always be available for a user or group.

Are drillhole HoleIDs case sensistive?

kbadmin — Wed, 05 Nov 2025 03:46:28 GMT

Yes Discover Drillhole tools was compare HoleID primary keys with case sensitive.

There is a validation option to check for Collar name mismatch, this will return any HoleID values which are not found in the Collar table, including case differences only.

It is recommonded to convert all HoleID field values to upper case to avoid issues.

Is MapInfo SQL and Expression case sensitive?

kbadmin — Wed, 05 Nov 2025 03:43:33 GMT

For char or string fields, MapInfo expressions and SQL statements are NOT case sensitive.

For example if a cell value was "Test" then if the expression was Value = "test" it would return true.
