Openlayers 4 – a parametric view is defined in Geoserver, and flitered in Openlayers through javascript – filter parameters are retrieved through an Ajax request querying the source layer in Postgres/Postgis. The layer is refined and point locations are returned and displayed. In addition, on-click events trigger retrieval of point attributes based on GeoJson.
A corresponding bounding-box is returned through an additional Postgis request, querying st_extent of the features’ geometries.

This process is in-line with a larger project establishing a GIS online system across government and other institutional sectors – initially supported by Spatial Ventures and Alcis (UK) through a feasibility study and needs assessment for implementing a GIS-based information platform.
This was great opportunity in October this year to understand the principles of operating fixed wings and copters with Uni Adelaide and CI. Also the insight of associated data lifecycle was interesting to go through. Overall, a nice option for monitoring the landcover and observing conservation related issues/outcomes.
Great article on vegetation indices developed from drone imagery
