Broken links to IPEA gpkg files

[ropinho]

All links to download geographic data from IPEA is broken returning 404 (Not Found).

Hence, the generation pipeline described in instance generation README.md finish unsuccessfully. The generate.py script fails to find the *.gpkg files in the data_raw directory, raising following error:

fiona._err.CPLE_OpenFailedError: ./loggibud/loggibud/v1/instance_generation/../../../data_raw/33.gpkg: No such 
file or directory

The (broken) links used in download.sh script are:

• https://www.ipea.gov.br/geobr/data_gpkg/census_tract/2010/33.gpkg
• https://www.ipea.gov.br/geobr/data_gpkg/census_tract/2010/53.gpkg
• https://www.ipea.gov.br/geobr/data_gpkg/census_tract/2010/15.gpkg

Thanks for the report. I believe IPEA changed the path internally. I'll investigate this further.

I'm also experiencing this issue, will this be updated soon?

[gabisurita]

By checking the metadata from IPEA (available at this CSV), I believe that the new paths are:

https://www.ipea.gov.br/geobr/data_gpkg/census_tract/2010/33census_tract_2010.gpkg
https://www.ipea.gov.br/geobr/data_gpkg/census_tract/2010/53census_tract_2010.gpkg
https://www.ipea.gov.br/geobr/data_gpkg/census_tract/2010/15census_tract_2010.gpkg

But I couldn't validate if anything else changed, and the rest of the pipeline still works. @Pinho @minterciso Maybe you can check if just changing the paths and renaming the files work. I shall check this in a couple of days.

@gabisurita I used these links to manually download the files (using curl) and placed them into the data_raw directory. The instances were generated successfully.

Therefore, I believe that replace the links in "download.sh" fix this issue. I can test this and open a PR if all OK.

Solved by #28 .

We should also fix the README links, but I'll keep this closed since the script is already working.
