Greater Manchester
Planning and housing in Greater Manchester
• Understand delivery of housing and employment land in GM
• Provide information on site constraints and opportunities for LAs and developers.
• Developing a joint spatial plan across the ten authorities.
• 2017 become the Mayor’s Plan - devolution • Need a joint and consistent evidence base and
understanding of land supply across the conurbation.
GM Mapping and Data Sharing
• MappingGM draws together public and private sector data about physical and social infrastructure in GM.
• Enables public sector, private sector and citizens to understand spatial dimensions of GM.
• Work closely with OS and Cabinet Office to develop.
• Linking with GM Connect
The brief • GM is undertaking a joint spatial framework and we
need to understand our land supply. How can we reduce duplication of effort, bureaucracy and engage residents?
• Once we received the sites how can we assess them more efficiently? We know that there are a huge number of planning constraints that we need to spatially understand.
• Sites need to be accurate using an OS base layer.
• The tool needs to easy to use and work for all ten local authorities.

GMODIN
• Over 60 layers of social and physical infrastructure. • Freely available and most data accessible and downloadable • Open to public mappinggm.org.uk/gmodin • Closed map for GM family with additional data
GMSF – Call for sites submission map
• Submit site by drawing on map
• Fill in site details • Overlay with existing land
supply • 40% of sites submitted
via map saving 6 weeks of planner input time.

Call for sites submission process
LA call for sites Site submitters return sites via form in post or
Sites digitised to GIS system by planning
officers
Sites assessed by LA on GIS system and
added to database
GM call for sites Site submitted to mappinggm with
supporting evidence
Sites assessed by LA on mapping GM
Local process
GMSF process
Call for sites assessment process
Review sites on local GIS system
Sites assessed via layers on system and paper layers
Data drawn from GIS systems added to databases and
spreadsheets
Officers summarise data, add to Access
database, Excel spreadsheets and local records
Review sites on mappinggm call for sites ‘assessment
page’
Automated stats and information about sites drawn from GIS layers
pertaining to sites
Officers summarise data on mappinggm for all to view
and provide local context to key stats

GMSF – Call for sites review and assessment maps
Point vs Polygon Point Polygon
Shows the location of site or area. Shows the extent of a site or area.
Provides general location information. Provides exact extent of area which allows decisions to be made.
Does not show all land holdings site may cover. e.g. overlay with Land Registry site data.
Will show all land holdings site may cover if overlay with Land Registry site data.
Benefits of new process
• Reduction in officer time uploading and downloading layers.
• GIS analysis uses specialist skills as opposed to showing where things are.
• Officer time saved in digitising sites.
• Officer time saved in reviewing sites.
• A common GM view of the key datasets to assess sites.
