rupestrecamposon Strategies to download data constantly changing via API

Thanks for your point of view, I appreciate very much. About data freshness, we would like to serve on our system the same information that you can find on the source website, and we have a few tickets pointing the difference to solve, so maybe the continuous strategy each hour may minimize it as today we do it once a day.

Brazil´s Farms, Rural Environmental Register data map.

+300Gb data updated monthly, for $7 besides what was already at home (internet, hardware).

rupestrecamposon Why login to get public data?

Thanks for pointing it out, will try to use it when needed. I could put it on internet archive problem is it is updated in a daily basis so uploading to there we could more likely create a temporal analysis rather than use it for real. Other problem that some datasets are kind of big, between 1Gb and 300 Gb

rupestrecamposon Why login to get public data?

I understand but the problem is that we need bots or someone will have to do it manually, and believe me we deal with a lot of layers, daily.

There are other methods to limit bad behavior like having usage limits and issuing a 429 too many requests in case of not respecting it.

For other countries to not access data, they could issue a api key or create a geofence to block external IP´s.

There are developer friendly ways to do it all, but it seems they are moving to a pattern to have massive amount of real people downloading the data instead of analyzing it, what a waste!

rupestrecamposon Ask HN: Did you personal website help you get hired? Tell about it

After +5 years working for companies building their own geospatial platform, I felt like I needed a portfolio for showcasing my skills to get a new job, without spending more than a few bucks.

So I created https://car-viewer.streamlit.app/ and a few others that you may find in contacts link at top.

The idea was to show and keep updated a massive (+250Gb) dataset on map on my own end to end using open source and proprietary tools within free tier limits.

After releasing it I got interview invitations that led me to a new job.
