Local Grid: Having error AttributeError: type object 'QgsCoordinateReferenceSystem' has no attribute 'WktVariant'

[jfpalomeque]

Hi, I am trying to use Local Grid, to transform some local coordinates into wgs 84, but whatever the projected CRS I am choosing, I am having an error: AttributeError: type object 'QgsCoordinateReferenceSystem' has no attribute 'WktVariant'

Hi,

I haven't seen that error before. Are you referencing your local grid to a Projected coordinate system or latitude/longitude. You will need to use a projected system.

Regards, Roland

Hi Roland, Thank you so much for answering so fast. I think I can attach the screenshots. I have tried a bunch of projected crs, like EPSG:32420, EPSG:32230 and EPSG:28355 (I tried the last one, even when the coordinates are in the UK, because I saw was used on your website. And I am always having the same error. I am using Qgis 3.8.3-Zanzibar. Thank you so much again

Hi Juan,

From the screen shot it looks like you are trying to put latitude and longitude in where they should be UTM coordinates. Most UTM have 6 digits for the easting and 7 for the northing.

Hi Roland,

I have converted the coordinates to UTM, and I am having the same error.

Could be an issue with my QGis installation?

Thankn you so much!

Hi Juan,

It is possible that something has changed in the QGIS API. I'm travelling now, so will need to look at it when I get home. Remind me next week if I don't get back to you.

Regards, Roland
