Upgrade the current version of ESRI GIS, in line with NGN GIS strategy with 24/7 third line support of the GISApplications.
Provision and establish the IT Infrastructure to operate all the core components in the new system from NGN’sAWS secure virtual private data centre.
Rebuild the Interface into SAP. The current interface is bespoke to NGN and does not have graceful failureor rollback capability. NGN would like to adopt an ‘off the shelf’ interface that requires configuration only andutilises the SAP Geo Enablement Framework (GEF) sync framework for example.
NGN proposes that the current version of ESRI GIS needs to be upgraded from the current version of 9.3.1 to the most up to date version of ESRI GIS.
As NGN will be migrating from the geometric network model to the utility network model it is expected that considerable data transformation and cleansing will be required as part of the upgrade. As the current version of the write instance of the ESRI database (9.3.1) does not have a direct upgrade path to the latest version, a non-conventional upgrade path may need to be considered including possible use of extract, transform and load (ETL) utilities from ESRI and third parties.
This data cleansing exercise would need to be done across all individual demarcation layers of the current ESRI GIS estate. For example, there are some aspects of GIS which NGN do not use now that could be removed as part of the data cleansing. This would need to be in line with NGN's Data Migration Strategy' (available in the Glossary section of this scope) which includes the production of logical and physical data models, ETL mapping documentation and data profiling analysis.
Any design submitted within a tender response will be subject to review against NGN AWS design principles and a secure by design principle.
GIS landscape should be COTS or with minimal custom development. It should have least dependency on the bespoke solution.
Minimise the manual intervention and automate the process as far as possible (like data updates from the measurement technicians).
NGN GIS roadmap should in future be capable to perform locational driven spatial analysis in SAP HANA.
Eventually data edit process and needs to be improved and move to faster data update mechanism, as NGN needs its GIS infrastructure to support a more optimised process with near real time updates
GIS database is updated with approx. 2000 updates a week, with 9 editors on average. There is no major performance related issue in the current editing system.
Ability to extract ‘delta’ changes from core dataset to provide updates to third parties, this includes the ‘North East Utility Asset Register.’
Ability to move any system or application within the GIS platform currently on Oracle Database to HANA Database.
