As of February 2019, you'll find a list of 2600+ open data portals around the world on OpenDataSoft's website. It lists as of now 2600+ portals ranging from the US (obviously) to Afghanistan. The story behind it: Working for a SaaS company in need of loads of structured data, our team started to compile a list of all open data portals around the world as ...

Take a look at what OpenStreetMap does. There's a page describing the nature of tile server disk usage. If you go up to zoom level 18 worldwide, you're talking about 91,625,968,981 tiles, which would take around 54000GB of disk space, but would mostly never be viewed. So I'm not sure if it would ever be a sensible approach, but having said that, I heard ...

Example: I only know of the company Cloudmade because they provide (a now outdated, but fine at the time) download portal of ready-to-use shapefiles derived from OSM data. Though this service might have helped its competitors, they probably earned much more in terms of visibility, which might spawn e.g. development contracts for custom-made solutions. This ...

Ideally, like @Andrew - OpenGeoCode mentions, you would release it in multiple formats. I would really suggest you look into organizing it into a e-book written in Markdown and hosted on Github. There are several advantages to this such as a built-in change log, being able to let people to (publicly) fork your document(s) and share their changes with the ...

Transmodel is a not very widely used format for schedule data (alternative to GTFS). For real time data (alternative to GTFS-realtime): SIRI is an XML protocol used most heavily in Europe. You'll want to consider what formats developers are most aware of and any possible performance issues. TRANSMODEL has been adopted as the European experimental ...

There are some great resources here. I would like to add http://knoema.com to this list. They are possibly the most comprehensive and constantly updating resource. All their data is free to use and links back to source. Plus the data exploration tools and search engine is pretty useful. Their dataset explorer is here: http://knoema.com/data I found that ...

Regarding this question, I think this post by Denny Vrandečić (the project leader of Wikimedia's Wikidata) is well worth reading: https://plus.google.com/104177144420404771615/posts/cvGay9eDSSK Denny knows very well what he is talking about. I'll just quote the first sentences as a teaser: tl;dr - If you publish data, attach the CC0 license to it, but ...

The basics for FOIA are: be very clear in your request be respectful be tenacious Remember that while there are government officials who are hostile to records requests, not all of them are. There are many people in government who want to do the right thing. There are a few websites designed to help you file FOIA requests. In the US, Muck Rock has been ...

Another system of interest for your list would be the OKFN Global Open Data Index: https://index.okfn.org/place/ It provides national and sub-national catalog listings and categorization for a variety of data types, and an assessment of how open each country is. Similar to DataPortals.org, and run by the same people.

GitHub has all the things, seriously, it rules. OKFN hosts open data there. So do I. As do most Code for America brigades. But you can also get a free datahub.io account, at least for an organization and you can upload there. You should also check out your area. Here in Virginia, there is an OpenVA data portal, and anyone can upload related data after ...

Quick answer with what comes to my mind. They might be several others. Advantages Since you lower the barrier to access the data (no more scraping), you will see more people using it and new usage of your data will appear You will also receive feedback regarding your data quality (since there is more eyes looking at it under different angles) This can be a ...

I'm sorry to hear you had a frustrating time uploading to datahub.io and that the site wasn't clear enough about the size limit. Another datahub-like platform that we have worked with in the past is data.world. Their size limit is 500MB.

My experience, making maps from quite a few government datasets: For point data, CSV is the best, with "lat" and "lon" columns. Very easy to work with in a wide range of tools, including text editors, spreadsheets, etc. The only downside I've come across so far is that GDAL sometimes requires you to make a .vrt companion file. (EDIT: Another downside is ...

The other suggestions on here are great, and I would echo the recommendation to consider Github if you want people to be able to easily edit your product for creating their own versions. This will also help you track the edits that have been made so you can learn more about what people do with your manuals. If you want to learn more about the definitions ...

The format should fit the data structure not the need of the comsumer (or the one who uses the data). If the data is semantically stored in a json structure you can easily export the data in different formats. So my answer is: json Check https://schema.org/Event

The first step as you said is to define which types of entities need to be removed in the public version of the data set. One example of such definition in the United States is given in the Health Insurance Portability and Accountability Act (HIPAA) rules, which target medical texts. According to HIPAA rules, the following information should be removed from ...

If you want quick, dirty, and free, you can always host downloadable datasets at the Internet Archive (archive.org). No pretty interface, but as much storage as you could ever want.

I'm starting to think that nobody really has a systematic way of finding datasets. With that in mind, I recently made OpenPrism so I could search 100 data portals at once.

'Finding' data is a really hot topic. (Would love to up-vote but am too new). It is something I am asked a lot about at work. We call the process 'Data Landscaping'. In terms of sites http://www.programmableweb.com/ can be useful - but often comes a bit light. We would then start with data marketplaces and data providers (http://www.quandl.com/ for ...

I've also found DataBullet.in and Enigma Public Data Explorer to be helpful. Also, a recent social network called data.world has tons of interesting stuff.
