How can I contribute with the Land Book?

You can contribute to the Land Book by sharing datasets / indicators related to land with the Land Portal, so we can include them in the Land Book.


How could I share datasets and indicators to be added in the Land Book?

If you are interested in add datasets and/or indicators to the Land Book, please let us know by using our contact form. If you are unsure whether these datasets or indicators will be of relevance to the Land Portal, be sure to check if your collection corresponds with one or more of the Land Portal's overarching categories, themes or concepts.


What are the benefits of contributing to the Land Book?

  • Join an active community working to address land issues at the global and local level
  • Expand the dissemination of your work by attracting new visitors from the Land Portal to your site
  • Enable the reuse of your content through the Land Portal's Linked Open Data (LOD) interface 


What is a dataset?

A dataset is a collection of data, published or curated by a single agent, and available for access or download in one or more formats (Excel, RDF, CSV...).

Currently, we are compiling datasets with data about indicators. The metadata that is is need by dataset is:


What is an indicator?

A (statistical) indicator is the representation of statistical data for a specified time, place or any other relevant characteristic, corrected for at least one dimension (usually size) so as to allow for meaningful comparisons.

The metadata that is is need by indicator is:

  • Name
  • Description
  • ID
  • Dataset related
  • Max / min possible values
  • High/Low (High means it is better to have a high value, low means the best value is the lowest one (like in rankings))
  • Measurement unit
  • Coded value (yes/no) (The values for this indicator is taken from some controlled term list (could be characters, colors, strings, numbers...))
  • Related concepts, themes and overarching categories from the LandVoc


What data itself is needed?

For each indicator, we data itself is as simple as: 

  • Country (preferred, ISO 3 code)
  • Year (YYYY)
  • Value​

For example, the data for the indicator A should be something like:

Country Year Value
AFG 1990 7.5
AFG 2000 8.5
AFG 2010 10
ALB 1990 4.6
ALB 2010 6
BEN 2000 3.1
BEN 2010 8.3


In our github, you can find examples of spreadsheets that we have processes to import the data into the Land Book:


I have a land dataset related, how will be the process to include it ?

Well, first drop us a line using our contact form. After that, we will contact you in order to find the easiest and fastest way to include your indicators and datasets in the Land Book. 

Technically, the flow will be:

  1. Read / Understand the data.
  2. Human pre-process of the data.
  3. Run an transformation process to generate an RDF file from your data.
  4. Upload the RDF generate in the Land Portal LOD triple storage (Virtuoso).


What will be the situation of my data at the end?

For each indicator and dataset shared , the Land Book team will publish a specific page, including all the metadata. The metadata of each element may be enriched during the import process.

Also, the indicators will be selectable in the Country pages and the Thematic pages.

And, of course, your data will be Linked Open Data (LOD), and will be available not only for the Land Book, also for other parties, using the capabilities of LOD (such as SPARQL queries).


As default, we license all the data processesd as Open Data Commons Attribution License, that summarizing, it is a license that allows:

  • To Share: To copy, distribute and use the database.
  • To Create: To produce works from the database.
  • To Adapt: To modify, transform and build upon the database.

As long as the person that uses the data:

  • Attribute: You must attribute any public use of the database, or works produced from the database, in the manner specified in the license. For any use or redistribution of the database, or works produced from it, you must make clear to others the license of the database and keep intact any notices on the original database.
