GeoJSON Service for FileManager
-------------------------------
Key: OODT-436
URL: https://issues.apache.org/jira/browse/OODT-436
Project: OODT
Issue Type: New Feature
Components: file manager
Reporter: Paul Ramirez
Fix For: 0.5
Create a GeoJSON service much like the GeoRSS service. The GeoJSON spec is
fairly simple but will expand on the GIS functionalities of the FileManager.
Supporting this will allow us to support things such as Feature,
FeatureCollection, Point, LineString, Polygon, MultiPoint, MultiLineString,
MultiPolygon, and GeometryCollection. This would be the GeoRSS on steroids and
should allow other properties to be associated with each feature.
Fundamentally, we can think of each product type to map to a FeatureCollection
and each product to be a Feature. Moreover, we can use this GeoJSON service
endpoint to work in a couple of modes.
The first would act as a layer which consisted of all products (Features in a
FeatureCollection) and should support probably support paging or some other
mechanism to limit the number of features returned (maybe zoom level).
http://localhost:8080/geojson/{product_type}
The next would act as the GeoJSON for a particular product (i.e. return a
Feature):
http://localhost:8080/geojson/{product_type}/{product_id}
The config should allow different mappings per product type (i.e. different
metadata mappings to the Feature).
Given the GeoJSON spec we should also remember to map the id property in the
Feature to the product id. Once this is completed we should be able to easily
plug the service into anything that supports GeoJSON and a great demonstration
would be to do this in Leaflet
