Dataverse and geo-spatial data

[Luís de Sousa]

Dear all,

first of all, my apologies if this topic has been discussed already but there is no search function in this forum. The user guide includes a short section on geo-spatial data [0], that raises more questions than answers. I can try to condense my doubts at this time in the following questions:

 1. The guide references a single vector file format, the outdated shapefile. What about state-of-the-art formats like GeoPackage or GeoJSON? Is there a list of supported vector formats somewhere?

 2. No reference is made to raster data. Is it at all supported? Which file formats? I would be mostly interested in GeoTIFF and VRT.

 3. What is the level of support to OGC web services? Are any services created once a geo-spatial dataset is loaded into the platform?

 4. Is it possible to add a OGC service as a dataset? What level of geo-spatial interoperability is provided by Dataverse?

 5. The user guide states: "in order to map your data file, a copy will be sent to Harvard’s WorldMap platform", this leads to two fundamental questions:

  5.1. what if the dataset is a multi-GB raster file?

  5.2 what if the dataset licence prevents distribution to third parties?

Hopefully that is not too much for a single thread. Regards.

Hi! The short section you found should probably link to the longer section at http://guides.dataverse.org/en/4.9.2/user/data-exploration/worldmap.html

There you'll see that in addition to shapefiles, maps can be created from tabular data such as Excel files or CSV files with latitude/longitude coordinates, census tracts, zip codes, etc.

Only published, non-restricted data can be sent from Dataverse to WorldMap.

I don't believe there's any support for the other items in your list but I will at least mention that when you send data to WorldMap, it will created GeoJSON and GeoTIFF and other formats, which we've thought about linking to from the Dataverse side: https://github.com/IQSS/dataverse/issues/1404

Please do feel free to open a GitHub issue to link the page you found to the longer one.

I hope this helps!

Phil

Hello again,

would there be any other medium to address in order to obtain answers to the questions above? Philip Durbin partially addressed question 1, but all the other questions are relevant.

Thank you.

Dear Durbin,

Thank you for your response. I wanted to ask if the Dataverse structure has recently changed regarding the upload of files—such as an XLS or CSV containing latitude and longitude columns—so that the system correctly recognizes them as georeferenced data.

I have installed Dataverse 6.10 and tested the same process on demo.dataverse.org, but the outcome is identical. I am unsure how to specify to the system that a file within a dataset is georeferenced.

I greatly appreciate any support you can provide.

Hi Humberto,

This thread is quite old and I'm sorry to say that WorldMap doesn't exist in the same form anymore and as such the integration between Dataverse and WorldMap no longer exists. We made this announcement in 2021 here (and perhaps a few other places): https://groups.google.com/g/dataverse-community/c/gJUFAFCUnP4/m/S7nVy-2QAgAJ

Can you please say more about your use case? If you want, you can still add "Geospatial" under "Tabular Data Tags" to a CSV with lat/long columns as shown in the screenshot of those old docs you found: https://guides.dataverse.org/en/4.9.2/user/data-exploration/worldmap.html

In the past, this was a prerequisite for creating a map out of the file. These days, it's just a way to add additional metadata to a file.

I hope this helps!

Phil
