A database of postcodes/zipcodes and the corresponding spatial locations in terms of a latitude and a longitude (or similar coordinates in an openly published coordinate system). The data has to be available for the entire city.
| Question | Answer | Comment |
|---|---|---|
| Available in bulk | No | Zipcodes are not available. |
| In an open format | CSV, DBF, GeoJSON, KML, SHP, SHX | GeoJSON files can be downloaded through the “API” link. Shapefile extensions are also available in .CPG and .PRJ. Spreadsheet comes directly in .CSV. |
| Available free of charge | Yes | |
| Up-to-date | Yes | There is a statement in the webpage saying that it was updated 2 months ago. |
| Available free online | Yes | |
| Openly licenced | Yes | |
| findable | 2 | It was not very easy to find this map, even though I’m acquainted with this platform. It took me some time to realize that I had to click on the search button without a query in order to get the full list of datasets and then search for the location dataset I was looking for. A specialist in the area helped me finding it. |
| findable_steps | 1) I looked at the website of many different sources from Rio de Janeiro’s City Hall, but I had trouble finding the correct link. I consulted with a specialist for help. Finally, when I came to the link above, I downloaded it but I couldn’t understand very well what kind of data was there, so I came to the specialist again to help me figure out the content of the dataset. | |
| licence_url | https://portalgeo.pcrj.opendata.arcgis.com/datasets/3b25 | The same link for the map above also displays a license in the footer. It is a Open Database License. It also has a mention to “public use” of the data at the same link. |
| Collected by government | Yes | |
| usability | 2 | There are many formats in which data are available, but you should have some knowledge on geographic datasets in order to work with this (including knowledge in geographic softwares). |
| collector_name | IPP - Instituto Pereira Passos | The Pereira Passos Institute (IPP) is the research department for Rio de Janeiro's City Government, responsible for collecting data, strategic planning and public policies integration, mapping, cartographic production and geotechnology application. |
| characteristics | Addresses, Coordinates (latitude, longitude), Data available for entire city | When I downloaded the spreadsheet available, I could get the information by addresses for the entire city, but I couldn’t get zipcodes and coordinates. However, the specialist I consulted said the last column, “shape_length”, had the intrinsic coordinates that could be accessed through a GIS software, if I downloaded it in shapefile format. So I considered that this information is available. Zipcodes are not available though. |

Reviewed. Changed B5 to No because zipcodes were not available.
