[workshop A]
where next?
opportunities to make the data we have more reusable & useful
some differing uses on gov.uk
* image stolen from Paul Downey @psd
some questions for discussion
- how can we maximise use and reuse the data?
- data on government services or through others?
- what helps others find our data?
- what is the data that we always need?
- what is missing?
- what things from across public sector would we consolidate onto overview pages? should we?
- what questions require consolidation?
- what could be the common consolidation points?
- can we meet multiple uses?
- what about look and feel and personalisation?
- where are the opportunities for collaboration?
spatial data
quite simple & not so simple
points, lines & polygons
and...
coverages & grids
imagery
and so on
not always (directly) represented
by coordinates
e.g. addresses or regions
coordinate reference systems
as simple or as complex as you make it/need it*
OSGB, WGS84 & ETRS89
*and I'm not mentioning projections
formats & standards
INSPIRE (legislation)
(this is not a plug for but a recognition that
there are some things we have to do)
WMS, WMTS, WCS, WFS
KML, GML, GeoJSON, CSV,
shapefiles, GeoTIFFs, MapInfoTAB, ASCII Grid, etc *
*there is a lot and some have traditionally had differing uses
what we have
(not exhaustive)
widely reusable to very niche
and maybe not that useful
4000+
location datasets & services*
*on data.gov.uk & some double counting
340+ WMS & WMTS
services*
*on data.gov.uk & many with more than 1 layer
60+ WFS
services*
*on data.gov.uk & much more due
50+ downloadable
spatial datasets*
*on data.gov.uk and gov.uk & much more due
1000's csv's
with geo-referenceable information*
*on data.gov.uk and gov.uk
900+ public bodies
publishing spatial datasets*
*on data.gov.uk and gov.uk
base mapping services
(in no particular order)
Ordnance Survey (including OnDemand),
Google, OpenStreetMap, CartoDB,
MapBox, Bing, ESRI, etc...
reference data
underpinning, commonly used data or elements
consolidated data
things about place that could be brought together
consolidation around
home, street, property, community, points of interest,
catchments, rivers, council and national park areas etc
what scenarios would lead to wanting consolidated data?
is my property (house, farm or business) at risk of flooding?
what do i need to do before I...?
etc
the discussion:
discussion points
-
how can we maximise use and reuse the data?
-
data on government services or through others?
- what helps others find our data?
-
what is the data that we always need?
- what is missing?
- what things from across public sector would we consolidate onto overview pages? Should we?
- what questions require consolidation?
- what could be the common consolidation points?
-
can we meet multiple uses?
- what about look and feel and personalisation?
- where are the opportunities for collaboration?
