Aylesbury Vale District Council provides an excellent example of a local authority that has implemented GIS within the context of a strong corporate approach.While many local authorities may find this level of corporate commitment difficult to sustain, the case study identifies the many advantages that can accrue from this approach, including unambiguous setting of priorities, integration of systems, and introduction of data standards, all underpinned by the necessary staff and financial resources to make it happen. ©2004 by CRC Press LLC Key Stages in the Implementation of GIS Stage 1 (1994 to 1997) — Initial experimentation with two GIS products (FastMap and Geobuild). Stage 2 (1997 to 1998) — Consultancy study to recommend strategy. IS/IT strategy adopted. ESRI (UK) Ltd. selected as GIS supplier. Stage 3 (1999) — GIS, LPG, planning, property and land charges systems implemented with associated data capture. “First cut” BS7666 LPG built. Stage 4 (2000 to 2001) — Contracts management and insurance records databases and building control system implemented with associated data capture. Electoral registration database matched to LPG. Positive Drivers and Success Factors for GIS • Adoption of corporate IS/IT strategy and provision of associated funding for GIS • Dedicated project manager and project team for implementation, with secondment of key staff • Users receptive to introduction of new technology • Constructive relationship with GIS vendor • Pressure to achieve e-government targets Problems that Threatened Success • Poor quality source data needed cleaning in advance of data capture. • Capture of graphic planning history data took considerably longer than anticipated. • Teething difficulties with interface between planning and land charges systems. Practical Benefits from GIS • Map base and associated data available with fingertip access on the desktop • Enquiries dealt with quicker by reception desks and other users (e.g., planning, land charges, property, contract management, and building control departments) without reference to paper sources • Planning applications registered in less time (30-minute savings per application), and accuracy of constraints check improved • Accuracy of land charges search responses improved, with future potential to improve response times • One position eliminated in land charges section through improved efficiency • One position eliminated in development control as land charges searches no longer required manual check • Resources no longer needed for updating duplicate manual map sets 13.1 WHY WAS AYLESBURY VALE DISTRICT COUNCIL CHOSEN AS A CASE STUDY? In the mid-1990s Aylesbury Vale District Council began to experiment with using two different GIS products on a departmental basis. While the Ordnance Survey liaison officer was using FastMap (from Survey Supplies) for map production and management, the planning department had selected Everest (from Geobuild) for ©2004 by CRC Press LLC digital preparation of the graphics needed to compile the local plan. As a result of concern that the authority was dissipating its efforts on competing GIS products without a clear consensus as to future direction, a GIS strategy study was commis-sioned from independent consultants during early 1997. AylesburyVale District Council provides an excellent example of a local author-ity that has implemented GIS within the context of a strong corporate approach. As a result of the consultancy study, the framework for future implementation of GIS was agreed upon within the adoption (in June 1997) of a corporate IS/IT strategy that established a strict single-supplier policy for GIS backed up by a substantial corporate budget of £1.03 million for GIS and related systems over the following 5 years.The authority movedaway from FastMap and Everest with the implementation of ESRI’s GIS products, which focused on ArcView on the desktop. While many local authorities may find this level of commitment difficult to sustain, the case study identifies the considerable advantages that can accrue from this approach: covering the unambiguous setting of priorities, channeling of staff effort, integration of systems, and introduction of data standards (including estab-lishment of the corporate LPG), all underpinned by the necessary staff and financial resources to make it happen. It is important to note that Aylesbury Vale District Council did not start from a strong corporate tradition. It moved from its early departmental experimentation with GIS to introducing a corporate approach as a result of recognition that corporate service priorities would be best served by improv-ing the ability of departments to use and exchange spatial data on a common basis. 13.2 THE BACKGROUND — WHAT HAS AYLESBURY VALE DISTRICT COUNCIL DONE? Aylesbury Vale District Council is an example of the implementation of a single-supplier/authority-wide GIS, using the terminology that we introduced in Chapter 8. Since June 1997, the council has strictly enforced the implementation of GIS based on the products of a single supplier as a consequence of adopting its corporate strategy. Three different GIS software products are currently in use across the authority: • ArcInfo 7 (7 licenses), which is used to support the processing of LLC searches • ArcView 3.1 (25 licenses), which is used across all departments for a wide range of tasks including map production, planning application processing, building control, forward plans, property management, contracts management, and insurance records • MapExplorer 2 (unlimited free product) which is used throughout the council for “cheap and cheerful” viewing of high-interest data within the GIS, especially at customer reception desks in the new customer services centers The development and implementation of GIS in Aylesbury Vale District Council took place over four major stages: Stage 1 (1994 to 1997) — Initial experimentation with GIS had begun with FastMap used for map management and production by the OSLO (within the engi-neer’s department) and Geobuild for digital preparation of the local plan. ©2004 by CRC Press LLC Stage 2 (1997 to 1998) — The consultancy project to formulate the strategy for GIS and identify the early priority areas for implementation was undertaken. The justification for investment in GIS was accepted and the corporate IS/IT strategy adopted (with GIS being one of the key elements). A substantial corporate budget of £1.03 million was committed for GIS, LPG, and related systems over the next 5 years. Following tendering, ESRI (UK) Ltd. was selected as the GIS supplier. Stage 3 (1999) — GIS software for map production and management was rolled out widely across the council, parallel with an extensive data capture program for planning, property management, and LLC. New processing systems for LLC and property management, linked to GIS, were implemented from CAPS (the local gov-ernment application software house within ESRI). The council’s existing planning application processing system was replaced by the CAPS uniform planning system and interfaced to GIS. As part of this stage of the project, an LPG conforming to BS7666 was implemented (using ESRI’s LPG Tools) and dynamically interfaced to the planning, property management, and LLC systems (with half hourly updates of change data to the planning and property systems; and overnight updates to land charges). The “first-cut” gazetteer (57,000 records) was built for the council by the data capture contractor as a text and graphic database (using council tax, National Non-Domestic Rates, ADDRESS-POINT, and the county council’s National Street Gazetteer (NSG) file). This database was enhanced in-house, resulting in a gazetteer that currently comprises 73,000 records; the database is now continually updated. Capture of other data also took place during this stage, covering land charges registrations (30,000 records), planning history (53,000 records), and land terrier (25,000 records). Stage 4 (2000 to 2001) — Implementation was extended to other areas, in particular contracts management (grass cutting, street cleaning, and litter picking), insurance records, and the introduction of a business processing system linked to GIS for building control. A second phase of data capture was contracted out to collect the data involved with the contracts management work. Over this period the LPG was submitted to Intelligent Addressing and further work undertaken to resolve the small number of anomalies in the data that were identified. 13.3 WHAT ORGANIZATION HAS IT SET UP? To support the implementation of the procurement phase of Stage 2 and the whole of Stage 3 of the corporate GIS strategy, the council established a GIS working party, which was an officer group with representation from each directorate, and from each of the business functions that were linked to the LPG. The GIS working party was chaired by the GIS project manager (see below) and reported to the council’s information strategy working group. The role of the working party was to: • Coordinate and facilitate the rollout of GIS throughout the authority • Resolve priorities between different projects when resources become overstretched • Ensure that steady progress was made with implementation of the LPG in terms of interfacing to other council systems, in accordance with the project plan ©2004 by CRC Press LLC To ensure successful management of implementation of the GIS, LPG, and associated business systems, the council appointed one of its existing staff as the GIS project manager (a user, rather than a technical expert, from the planning division who was transferred to the IT division). To support ongoing operation of the systems, the council also established a corporate GIS team (jointly managed by the GIS project manager and the information team manager within the forward plans division). The team consisted of a GIS officer (who is an experienced ArcView specialist) and an LPG technician. 13.4 WHAT DOES AYLESBURY VALE DISTRICT COUNCIL PLAN TO DO IN THE FUTURE? The council is currently upgrading all products used within the corporate GIS solution. This is intended to result in a solution that is considerably easier to support, exploits the most recent improvements in technology, and automates the connections to both the NLPG and NLIS. The council plans to continue the expansion of GIS, including links from the LPG, to other areas that can potentially benefit, in particular environmental health, the customer service center, council tax, and benefits. With the increasing emphasis on e-government, the council is currently putting in place plans to publish selected data from the GIS on its Website and to encourage interactive access. 13.5 WHAT WERE THE POSITIVE DRIVERS AND SUCCESS FACTORS FOR GIS? Much of the success of Aylesbury Vale District Council is due to a number of significant drivers and success factors that have helped to provide a climate of support for the project. The positive drivers that have been of particular importance prior to and throughout the project are: • The far-sightedness of the authority in recognizing, early on, the long-term benefits to service delivery that would accrue from adopting a corporate strategy for GIS within the framework of an overall IS/IT strategy. • Consequent on the adoption of the corporate IS/IT strategy, the commitment of substantial resources to the project at the outset, which enabled implementation to progress without interruption. • More recently, the imposed need to achieve the e-government targets has further strengthened the justification for the GIS implementation program that was already underway. The critical success factors that have underpinned the project and maintained its profile within the authority have been: ©2004 by CRC Press LLC ... - tailieumienphi.vn
