This interface is composed by two sections:
- The Map: a navigable world atlas by UN Regions.

- The Query: here shall be insert all the geoinformatic specifications on the SLM needed by the user. The query is a step by step process, once a details is selected, all the other sub-details will be prompted. In total, there are 6 steps:
Region → Sub-region → Country → Theme → Sub-Theme → Dataset(s)
1- Region | 2- Sub-region | 3- Country | 4- Theme | 5- Sub-theme | 6- Datasets |

Table 1: The query process
1, 2, 3) Select a region, then the sub-region and the countries of interest.
4, 5) Define the theme/topic of interest of that particular location. There are two themes to choose from:
- context/driver database will allow querying SLM actions and techniques with similar environments, based on their geographical, biophysical and socioeconomic context;
- outcome-impact database will allow querying SLM actions and techniques working toward the same goals.
Depending on the option selected, a variety of related sub-themes will be available for selection.
6) The last step is the datasets selection. Can be checked as many datasets as needed, please note that more datasets will require more loading time.
Once all the details have been defined, the "Apply" button will show the results in the output section.

- The Map: once the query process is over, the layers of the chosen datasets will be shown as by example figure.

- Selection
| Polygonal Selection | Box Selection | Point Selection |
|---|---|---|
| Draw a poligon around the regions of interest (ROI), this will select all related rasters, provide statistics about them and allow their download. | Inscribe the regions of interest (ROI) in a pre-defined 10x10 km box, this will select all related rasters, provide statistics about them and allow their download. | Define a poin within a region of interest (ROI), this will select all related rasters, provide statistics about them and allow their download. |

Legend
- Filter
The filter allows to toggle on and off specific rasters.

- Clear Layer Mask
This tool allows to clear a custom area from undesired layers.
- Download
The results of the analysis can be downloaded as .zip archive by clicking the apposite icon. 
- Value by Location: This table indicates the values measured for the active rasters in a pinpointed location.
- Summary Statistics: This table indicates the values measured for the active rasters in the whole country of a pinpointed location.
- Options by context: This table indicates the most applied SLM practice, as a result of the tool's calculation of the values measured in the area of interest.
