OpenStreetMap services for the village of Saint-Cergue in Switzerland are being set up to explore the latest developments in open data, analytics and visualisation for Location-Aware Data-Driven Intelligence Management (LADDIM). 

The main aim is to identify the LADDIM issues surrounding the co-ordinated integration and implementation of modern OpenStreetMap (OSM), Geographic Information System (GIS)  and Building Intelligence Modelling (BIM) technologies by small-to-medium sized consulting engineering firms in less-developed countries. Such activities are in part covered by the GeoBIM initiative (an example).

The aim is of course to demonstrate how LADDIM services are implemented for the assessment of  infrastructure and building projects so that guidance for users can be developed for commercial offerings which will surely come online.

As regard OSM technology, we have started with self-hosted:

  • OpenStreetMap (OSM) back-end tile server with an OSM base layer;
  • OSM web site to manage the editing of OSM data;
  • OpenGTS server to manage tracking using Android mobile phones;
  • OpenRouteService API back-end with the OSR front-end to display isocrones for walks in the Jura Mountains;
  • aoi-osm Area-of-Interest map;
  • Overpass server API back-end with a Leaflet front-end to mark points of interest.

Being tested are:

  • tag context analysis using an OSHDB API back-end server;
  • an Extractor for generating map extracts that are edited using JOSM and uploaded to the self-hosted OSM back-end;
  • a point-of-interest service such as openPOImap;
  • the layering of multispectral Sentinel2 satellite to help in identifying and perhaps monitoring map features such as vegetation, humity and soil exposure.

Details of implementations and applications will follow. Implementations use HP Proliant servers running Ubuntu 18.04LTS and open-source OSM front- and back-ends.

Links to the various services start from the OSM map at map.peterboswell.net 

As a personal interest, the OSM map includes a very recent, high-resolution Digital Elevation Model (DEM) relief layer (a swisstopo swissAlti3D product) for the communes of Saint-Cergue, Arzier and Bassins that covers the Jura Mountains above Saint-Cergue. The relief map is used in association with satellite imagery and OSM data to map items of historic, archeological and wildlife interest. The satellite imagery mapping is very much a work in progress.

The DEM was manipulated using QGIS's GDAL and GRASS tools. OSM map editing uses the JOSM editor although the OSM site offers the ID editor.  We have problems smoothing (de-noising) large, high-resolution DEM hillshades using fp_denoise and mdenoise. The smoothing is useful because it tends to merge roughness into consolidated areas that are less distracting and help highlight features at the sub one-metre level.

The hands-on mapping exercise helps in our broad review of the application of OSM technologies in consulting engineering. Of interest therefore are:

  • planning using urban topology (e.g. reblocking, openSidewalks, infrastructure utility);
  • location assessment (e.g., going beyond classic routing services - walkability, route optimisation, etc);
  • capital and investment monitoring (built environment - buildings, infrastructure; natural environment - land cover; nature-based infrastructure);  
  • spatial feature identification (e.g., Overpass4j, Orbis, OF4SOM, OSMonto);
  • feature attributes organisation (tags, indexes, ontologies, taxonomies);
  • physical modelling (e.g., energy, climate, sound, exposure, etc.) based on spatial analytics (e.g., ADEME, URCLIM and ANR CENSE programmes)
  • computer-aided mapping (aerial, satellite and ground-level imagery; AI feature extraction, e.g., buildings).

The aim is to place these technologies in the context of the consulting engineering industry's  planning, design, procurement, certification, and project management activities.

The importance of each of these technologies for consulting engineering is often not immediately apparent. In most cases, case studies are emerging, but judging the future importance and significance of the various technologies requires a detailed understanding and a careful analysis.
