[postgis-devel] [SoC] GSoC 2021 - Week 3 Report - Implement pre-sorting methods before GiST index building

[Regina Obe]

Han,

 

Yah regress/real is just to start the setup.

 

I was hoping you’d do a pull request with some more tests to that.  Basically whatever you’ve been testing but using the data provided via the download.

 

I have the basics of a testing bot going.

I think I mentioned that to you, but still need to make so tweaks.  When I’m done I’ll give you a link you can trigger tests from her.

 

I can also point her at your repo so she can test against your repo.

 

Thanks,

Regina

Hi Regina and hi Giuseppe,

 

I have tested with some real data in `osm_china` with .sql scripts. And it works normally with several outputs. But I think the details of /regress/read need to be modified for further uses.

 

Moreover, I would like to know how to prepare for the first period evaluation?

 

Best regards,

Han

Darafei and Han,

I packaged Belarus osm data up from https://download.geofabrik.de/europe/belarus-latest.osm.pbf

And have as an sql loadable script

https://postgis.net/extra/test-data/osm_belarus.sql.bz2

I’ve added it to the regress/real/download_data.sh script

I used ogr2ogr to load into PostgreSQL.  Not sure how it compares to osmium structure or if it matters much.

Thanks,
Regina
