GOLDENAI Graphical User Interface (GUI)

Description

The GOLDENAI platform considers the ingestion of different data sources into a data cube representation for a given area of interest (AOI). The platform consists of two main components: the back-end (mentioned as 'OCLI' hereafter) and the front-end (mentioned as 'GOLDENAI GUI' hereafter). OCLI provides a pipeline that processes AI Knowledge Pack (AI KPs) and handles the data mining process. It involves automated modules for data acquisition, data preprocessing, image processing (e.g., denoising, edge detection, etc.), and AI processing. In particular, for a given area of interest (AOI), it first collects the related satellite data products from the DIAS services, Euro Data Cube (EDC), EOS or Supplier's API. Then, it prepares analysis ready data (ARD) by performing data cleaning, transformation and filtering. The GOLDENAI GUI acts as a general repository of data in Cloud Optimized GeoTIFF (COG) format (processed from OCLI) which is straightforward to explore and exploit by the platform users. The GUI is an architectural approach for implementing a modern 2D and 3D visualization platform. It's powered by OGC web services and deliver EO, Drone (UAV) Sensing and Proximal Sensing data. This data could be interactively explored by the public and mine site owners, with different authentication and authorization access levels, in an easy, quick and efficient way as assisted by a conversational AI agent. 

GOLDEN-AI functionalities:

Following recent trends in data visualization, GOLDEN-AI GUI allows for so called "geospatial storytelling" – where sharing the results is wide-scoped in a sense that the results are presented in a way equally effective both with experts and untrained public.

The GOLDEN-AI GUI presents the following main features (Figure 1):

• Optoss GOLDEN-AI Assistant. In order to find the documents related to the field trials in Germany, Bulgaria, Romania, Finland and Kosovo the user can use a natural language query: "show me all products in Romania with a range of 250 km".
• Select and filter layers. The user can adjust Brightness, Contrast and Opacity.
• Select Base layer maps (Satellite imagery; Terrain 3D; Open Topo map; Nz-refill; and ThunderForest) from publicly available sources.
• Viewing pane tool. This stack of maps enables users to interact with different layers and can show up to 32 layers of GIS information from different sources at the same time.
• Inquiry Lens tool. This spyglass enables users to see through different layers in a dynamic way.
• Select/Locate/Zoom/Pan/Draw/Measure tools.
• Load local files (GPX, KML and GeoJSON formats). GOLDEN-AI GUI provides a very rich user experience that also allows users to define and save their Region of interest (ROI) through a drag-&-drop interface.
• 3D viewing mode with Camera positioning tool.
• DEM Amplifier. Allows the vertical exaggeration of objects for easier interpretation of the land topology on a common flat 2D screen. Applicable in situations where flat ground needs to be extruded to improve the understanding of the encountered phenomena.
• Dashboard with information about  Zoom level, scale and geographic coordinates (lat, lon) under the cursor.
