By selecting "Visualization" in the GeOC menu, the tool will load, prompt and ready for use.
Figure 1: Overview of the "SLM visualization" part
This interface is composed by two sections:
- Section 1: Query section
- Section 2: Map section

Section 1: Select By (GAUL)
Select by Region of Interest – Drill-down GAUL
- 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 |

FigureTable 1: The query process
Once the query is done, the output results will be shown up on the interface. Eventually, the interface will be divided into 4 sections:
- Section 1: You can see the Filter options – Drill-down by Gaul (Country, Region, Continent, & District).
- Section 2: There are some controls – tools allowing you to move around the map with the use of zoom in, zoom extent, zoom out, pan functions etc.
- Section 3: You can see the output result for Value by Location, Summary Statistics, and Options by Context.
- Section 4: You can see the report download.

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.

Value by Location
This table displays the values for each pixel.
Summary Statistics
This table displays aggregated information related to the user defined area of interest.
Options by context
This table displays the options ranked by frequency.
Section 4: Report Download
The statistics for the ROI and the selected rasters for the ROI are available for download by clicking the download icon

- 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.
