<ul><li><strong>Status</strong> changed from <i>Closed</i> to <i>Reopened</i></li></ul><p>Still does not work in QGIS 2.18. Tried on all platforms and if a field does not have at least one decimal, it will not be selectable as a Z field in the Grid (Interpolation) dialog. The workaround is to make sure that the data type of the field is real AND that the precision is at least one.</p> QGIS Application - Bug report #14597: Grid Interpolation requires Real data type with decimals for Z valuehttps://issues.qgis.org/issues/14597?journal_id=738362017-01-02T04:55:20ZGiovanni Manghigiovanni.manghi@gmail.com

For instance, the ELEV column is not selectable in the Grid (Interpolation) Raster menu item in 2.18.3 as a Z field. If you copy that column into one with decimals, it will then be selectable.</p> QGIS Application - Bug report #14597: Grid Interpolation requires Real data type with decimals for Z valuehttps://issues.qgis.org/issues/14597?journal_id=743272017-01-25T08:49:42ZEurico Nicacioeuriconicaciojr@gmail.com

<ul><li><strong>Status</strong> changed from <i>Feedback</i> to <i>Closed</i></li></ul><p>Works fine with Processing front-end. GDAL Tools is a deprecated plugin, use Processing instead.</p> QGIS Application - Bug report #14597: Grid Interpolation requires Real data type with decimals for Z valuehttps://issues.qgis.org/issues/14597?journal_id=752082017-03-10T11:48:15ZGuillaume Larocqueglaroc@gmail.com
<ul><li><strong>Status</strong> changed from <i>Closed</i> to <i>Reopened</i></li></ul><p>This is still a problem in 2.18.4. I gave a QGIS workshop and all 12 participants had this issue on all platforms. If the column type is INTEGER, it does not show in the list of fields in the Grid (Interpolation) dialog. The Processing Grid (Inverse distance to a power) option does not even allow to specify the output raster resolution and extent, so is not a suitable replacement.</p> QGIS Application - Bug report #14597: Grid Interpolation requires Real data type with decimals for Z valuehttps://issues.qgis.org/issues/14597?journal_id=778202017-04-30T23:05:46ZGiovanni Manghigiovanni.manghi@gmail.com
