Exegesis was commissioned by Zero Waste Scotland (ZWS) to develop a website and mobile app, plus the underlying database and API, to enable local authorities and other stakeholders in Scotland to monitor litter and fly-tipping incidents.

ZWS is the body responsible for reducing waste and promoting a circular economy in Scotland and has been a FlyMapper partner organisation since 2013. The Litter Monitoring System (LMS) took the pre-existing functionality of FlyMapper and added the ability to record and analyse detailed surveys of street litter. These surveys are used to support the requirements of the Scottish Government's Code of Practice on Litter and Refuse (CoPLAR).

The LMS mobile app is built using Xamarin, a cross-platform development tool that allows the sharing of a codebase between Android and iOS app versions.

The LMS web site allows management of both the fly-tipping and litter monitoring elements and is built within a cloudscribe Content Management System. It already contains details of previously recorded fly-tipping incidents in Scotland.

Data taken from the Technical support for CoPLAR Land Zoning in Scotland project is imported into LMS as local authorities continue to come on-board.

The development and User Acceptance Testing were undertaken rapidly to allow the volunteer surveyors to get out in the field as soon as possible - five weeks from design to deployment! The results were hugely positive with nearly 800 surveys quickly completed and all surveyors enjoying the process.

The National Park Conservation Officer concluded that this project had shown the way for future Heritage at Risk surveying, with significant advantages over previous methodologies.

In 2014 we are enhancing the app for a new round of surveying.

The system is currently in use by 12 Local Authorities in Scotland and 15 in Wales and had recorded over 80,000 fly-tipping incidents since 2014.

FlyMapper has two components: FlyMapper Web and FlyMapper Mobile. These are two ‘views’ onto the same dataset (if you add a record on the mobile you see it on web and vice versa):

FlyMapper Mobile:

• Smartphone app utilising GPS
• Simple to use
• Works on Android and iOS devices
• Works on and off-line (using local mapping)

FlyMapper Web – similar functionality to the mobile app plus:

• User registration management
• Analysis and reporting
• Data export
• WMS
• Optimised for office use on standard web browsers

exeGesIS worked with Bristol City Council to develop the methodology for the survey. We then used our Path Surveyor application to complete the survey, loading all the existing data onto handheld devices so that they were visible to the surveyor in the field. This enabled the surveyor to see what information already existed, update data on existing features where it was out of date and capture new features from scratch. This was done whilst retaining information that was still relevant.

A particular requirement for this survey was the capture of photographs for all features, not only for all furniture items (both new and existing) and for all issues, but also general photographs of the paths were required as well. These photos were captured on survey and processed via Field Data Manger into LibraryLink, where they are visible from the Council’s CAMS application.

Support is provided for entering data as CMSi monitoring projects associated with a site and for incidental records collected by volunteers. The module features a range of input forms that can be customised to suit a variety of recording needs. Data can be browsed from an intuitive tree interface, filtered, and viewed in the standard map window alongside other CMSi layers.

In addition, sophisticated reports can be specified using a wizard, which are then generated within the module and exported to GIS.

The system includes a mobile app (iOS, Android and Windows) and an API to communicate with the backend CMSi system. The mobile app is used by field surveyors throughout the GBNL consortium on iPads and a range of Android tablets. The surveyors record observations and sync these with the backend CMSi database. They typically deal with many thousands of observations and species dictionaries and data volumes are quite large.

The mobile app is map-centric and uses the device GPS and offline mapping for the entire country. The app also provides more advanced control over the map layers and allows additional KML and ESRI shape files to be imported and overlaid by the end user.

The technology used by the project is based upon a number of open source and open standards frameworks and may be deployed across a wide range of Android and iOS smartphones in the market today. The technical solution developed by the project follows a modular design and has been configured for use in each of the two mobile apps (Norfolk CC and Zeeland). This modular design is important as it allows additional functionality to be added by future projects and also allows existing modules to be re-developed or even removed as native technology in mobile devices develops. It also means that new mobile apps requiring a different set of functionality can be rapidly developed using existing modules with different configurations.

Each individual grave was accurately plotted on the GIS map. A high-precision differential GPS receiver was used, with aerial photography to support the GIS mapping. Once located, each grave was photographed, basic information and more detailed information on the condition of the headstone was recorded, and a detailed risk assessment was carried out.

The fieldwork was completed within less than a month by one of Exegesis' own surveyors, with full support from the office team. After this had been completed, Exegesis provided data analysis and reports to the client.

In order to create the indicative map we combined all relevant datasets into a single ArcGIS personal geodatabase containing over 1.8 million polygons. This geodatabase was linked to an Access database application that assessed the likely habitat based upon the reliability of each source dataset and suggested the most likely habitat for each input polygon. The assessment was made based upon an agreed rule base. Using this assessment the application generated a new personal geodatabase that incorporated the classification of each polygon by likely habitat and an indication of the reliability of the assessment. In this way we were able to incorporate all available data in the assessment of each polygon, rather than prioritising the data contained in certain datasets over others.

Using the Exegesis 'Path Surveyor' application, the survey team captured data on 24,000 features with 15,000 images. LAMS has a desktop component allowing trail managers to undertake detailed analysis and reporting and an advanced web viewer application based on Microsoft’s© Virtual Earth™ (VE). This project brings together the functionality and power of desktop MapInfo, the outstanding map and aerial imagery resources of the VE platform and an open source development environment to offer a very cost efficient solution.

The next step in the project is to integrate the LAMS web application into the Walk London website, allowing users highly flexible searches with information returned as maps, text and images – and even perhaps an option to use the 3D fly through capabilities of VE.

The quality of core survey data was optimised through the use of hand-held computers linked to Global Positioning Systems and the automated downloading of data directly to a central database eliminated errors that might otherwise have arisen during a manual transfer process. Advanced spatial analysis of the survey data was achieved using GIS.

Results showed that the frequency of serious problems (i.e. those that render a path unusable) along the network ranged between authority areas from 1 every 1.75km, to 1 every 400m. Nationally the frequency was 1 every 650m. It was concluded that the public rights of way in Wales were generally in poor condition and that this was preventing the full realisation of sustainable tourism, amenity use and the generation of potential health benefits to users.

Conclusions were drawn about the limitations of some existing approaches to monitoring network condition and recommendation made to improve annual monitoring surveys through the use of more rigorous sampling regimes, the convergence of evaluation standards and the adoption of a new 'best value performance indicator'.
