How can I contribute to the Land Book?

You can contribute to the Land Book by suggesting land-related datasets and indicators to the Land Portal team, so we can include them in the Land Book.


Can I share datasets and indicators with the Land Book?

If you are interested in adding 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, check if your collection corresponds to 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 on land issues at the global and local level
  • Check constantly the quality of your data with the help of the Land Portal team and community
  • Build robust set of metadata, allowing for a wider reuse of the data while always recognizing the original autorship.
  • Increase the visibility and the accessibility of your work and attract new visitors for your site from the Land Portal
  • 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 is an observation?

For each indicator, a single data point is as simple as: 

  • Country (preferably ISO 3 code)
  • Year (YYYY)
  • Value​

For instance, the data for a generic indicator would look like this:

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

You can enrich the basic Country/Year/Value structure by adding also a field with specific Notes.

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


What are the main steps when importing new data on the LB?

Well, first drop us a line using our contact form. We will get back to you and together we will 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 data and indicators once they have been ingested on the LB?

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 and can be easily updated over time.

Your indicators can be featured on different sections of the Land Portal, including country and thematic portfolios.

Also, your data will become Linked Open Data (LOD), virtually enabling an unlimited range of reuse options - but always with proper attribution and recognition of your work  - for both single users and websites.

By default, all data are granted with Open Data Commons Attribution License. In a nutshell, this license allows for:

  • Sharing: copy, distribute and use the data.
  • Creating: produce works based on the data.
  • Adapting: modify, transform and build new contents based on the data.

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.
