[postgis-users] Geometry Viewer in PgAdmin

[Shaozhong SHI]

Sometime, when clicking on the eye button in PgAdmin, Geometry Viewer gets into a mode to display background map with options like Empty, Street, Topography, Grey Scale, Light Colour and Dark Matter.

I am interested in making use of visualisation within PgAmin.

Are there any documentation or guides on how to make the best use of these in PgAdmin?

Regards,

Out of idle curiosity, I looked at Geometry Viewer.   It allows just one data display layer so you can only look at one table/query at a time. The style of the geometric objects is hard coded so you can't change their color, background pattern, line style etc.   It does not support color scales.  I can't think of any use case for which it would be useful.

I would strongly suggest using QGIS instead.  Not only does QGIS have all of the capabilities missing from Geometry Viewer but it will read directly from PostGIS tables.  Since it's so widely used there's lots of documentation and other learning materials; I counted five different Youtube beginner's tutorials.

I'd also look as DBeaver, it has a free Community Edition and a nice (but basic) geometry viewer for Postgis. Built in support for a good set of backgrounds as well. Postgis columns are auto displayed as WKT which I find useful.

For a user (vs admin) of a Postgis DB I think DBeaver is nicer than PgAdmin. It does primitive ERD's, which I don't think PgAdmin can do yet, but that might have changed since I last looked...

And you can access many other databases than just Postgres.

But I agree with Ruven, if you want to do more that a casual perusal of Postgis data, go QGIS.

Yet another reason to install QGIS is that it will read just about any GIS data format; the layer can then be saved as a shapefile which can be imported into PostGIS using the PostGIS Shapefile import tool.

Actually, you can upload basically any QGIS vector based layer directly into a PostGIS database (connected to QGIS). No need for a shapefile detour

Here is a github repository from my class that walks you through how to connect PostgreSQL to QGIS
