[Incubator] Resolve overlap and gap in Simple feature by using Postgis Topology

[Lars Aksel Opsahl]

Hi

Thank's the same, nice talking to you.

That's a good question about connecting this two applications. As today we are not there.

To get there we have to create config file compatible with this format https://gitlab.com/nibioopensource/pgtopo_update_sql/-/blob/develop/doc/APP_CONFIG.md and call function topo_update.app_CreateSchema .

I am not sure if we add to much functionality in to resolve_overlap and gap when doing that, so we may need to discuss where to place functionality like this .  Another option is also to have some kind  off reverse engineering  to make it more easy create app_config.file.


I also had chat when Even Roualt at Foss4g  where he mentioned that he and Sandro Santilli had chat about format for ogr2ogr and Postgis Topology some years ago.

So maybe we can make the connection you suggest at a later stage , when both this two applications are more stable and more set .  Then we also may know what role ogr2ogr can have here.

But for sure, as you suggest we need an easy way to enable the topology_update client for Postgis Topology data that already exists in the database.

Thanks.

Lars

Lars,

It was a pleasure to meet you last week and thank you for submitting these projects.

I have a question? Can these projects work independently or do they each require each other?

Other projects in this situation (with a client and server half) presented themselves as a framework when being shared with the public:

See https://www.osgeo.org/projects/gc2-vidi/ as an example.

Would this be a suitable approach for resolve overlap and gap and topology_update  applications?

Hi

Incubation committee:

I would like to ask permission to the list the project resolve-overlap-and-gap on the OSGeo website in order to share the work with more people!

In this project we clean up Simple Feature datasets by using Postgis Topology.

The repository is located here: https://gitlab.com/nibioopensource/resolve-overlap-and-gap released using GPL license.

My OSGeo userid is "laopsahl" and I will need permission to create a project page.

Thanks!

Lars
