In detail, we are trying to assess all french cadastral parcels, based on proximity to point of interest and distance to pollution / risks.
For pollution (ex: noisy roads), I have identified a source from ArcGis server. ex:
[login to view URL]
I have 2 needs:
1. Display the noisy road on a map, in a web app
2. Calculate, for each parcel (I have their geojson geometries), if a parcel is inside or not a noisy area. If yes, which noise level (=color).
For 1. we want a resilient solution, even if the gov decide to unpublish this map.
Can we remotely backup / restore on our own servers (ex: ArcGIS) ?
Can we remotely download all the content and convert it in geojson (all our datasets are stored in geojson format, in our mongoDB server) ?
For 2, which format shall we use to store the noisy roads to make our query ? geojson ? WFS ? WMS ? Other ?
