Over three separate contracts between 2012 and 2016 exeGesIS collated maps of GI delivery and captured the information, which was supplied in ESRI ArcGIS format. Maps were collated from local planning authority websites or the relevant Natural England casework officer. Collated maps were registered in GIS and areas of UK Biodiversity Action Plan habitats and other GI were separately mapped and attributed. In total, 753 cases were mapped amounting to 3,485 polygons (21,342 ha). As part of the first contract, the dominant land use was also extracted from Land Cover Map 2007 to indicate the habitat present prior to GI delivery. Brief reports were produced detailing the process and results, and summarising gaps in the information where maps were not available.

exeGesIS developed a methodology for monitoring GI delivery, making an assessment of the delivery agreement against the GI delivered. This was based upon Natural England's existing Integrated Site Assessment methodology and encompassed ecology, access, green roofs and other aspects of GI delivery. It also allowed users to create bespoke targets against which to assess the site, to allow site-specific features to be considered.

The methodology was tested on four sites in the vicinity of Hull in March 2013 that included a range of features. Targets were established based upon the delivery agreements for each site, against which the sites were assessed. Any targets that were not met were identified and discussed.

This work was further developed in a second contract. We facilitated a workshop to focus Natural England's requirements for the survey methodology and, using consensus building techniques, agreed a reduction in the number of assessed features to make the methodology more user friendly. We then redeveloped the survey form, consulting further with Natural England to ensure the survey was suitable to the target audience and easy to use. We also wrote a comprehensive survey handbook to be used alongside the survey form.

The work was documented in a report to Natural England that covered the methodology development, selection of survey sites, results, redevelopment of the methodology, an assessment of the appropriateness of the methodology and recommendations for further development.

Exegesis were contracted to create web mapping for iGiGL, the online data portal of the capital's environmental records centre. The portal provides access to detailed information on London's wildlife, parks, nature reserves, gardens and other open spaces.

The finished mapping system reveals different data depending on the role of the web site user, allowing GiGL to securely distribute datasets to only the people who require them. This is combined with a Content Management System, which allows much of the site and data to be edited by GiGL staff.

Further custom development work has:

• Allowed surveys designed by GiGL staff through the CMS to be submitted to an Indicia Warehouse.
• Added full layer editing functionality to specified layers.
