Site Overview

The Atlas website is designed to provide supporting information and downloads from the project as well as interactive webGIS maps of the wave, wind and tidal resource parameters.  The other supporting website pages offer more generic project information and also allow the user to download items such as the technical report, pre-prepared Atlas maps, underlying GIS layers and associated metadata.  The website is designed to be viewed using standard web browsers without the requirement for any preparatory client-side software.

The basic sitemap structure for the website is shown below and brief descriptions are given in the following table:

Basic Sitemap Structure

Brief Description of Available Web Pages

Area of site	Brief description
Introduction	The introduction provides a brief background of the Atlas and offers some quick links to key deliverables of the project including the technical report and pre-prepared Atlas maps.
Maps	Each resource has a dedicated Atlas webGIS map selectable from the main menu under ‘Maps’, which allows the user to view the key resource data layers with supporting baseline reference layers.
Downloads	This section of the Atlas website contains all available outputs for the current version of the Atlas.  From a GIS perspective this includes all resource data layers (excluding baseline layers) used in the online webGIS in both Mapinfo (tab) and ArcGIS (shp) formats (N.B. basic user data is required to be entered to generate statistics of key user groups that are utilising the data) and the metadata (xml) for all key datasets.  It is also possible to obtain a copy of the pre-prepared Atlas maps (reduced in quality for downloading off the web) and this technical report.
Project Team	A list of project partners involved in making this version of the Atlas possible are provided in this section.

Layout of Maps

Each resource has a dedicated Atlas webGIS map selectable from the main menu under ‘Maps’, which allows the user to view the key resource data layers with supporting baseline reference layers.  Each layer’s symbology has been constructed to maintain consistency with the pre-prepared pdf Atlas maps.  Several layers are available to view on the different map pages as summarised in the following table. 

Available Web Data Layers

Data layer group	Individual layer name
Baseline (Available each resource map)	Land UK Continental Shelf Bathymetry
Annual Mean Wave	Height Power (Full Wave Field)
Mean Tide	Annual power Neap Peak flow Power Range Spring Peak flow Power Range
Annual Mean Wind (100m)	Speed Power

The webGIS maps all have a standard layout and the following diagram highlights the different parts of the application that the user may interact with.

Summary of Data Enhancements

The wind and wave datasets have been derived from an increased archive of data (from 3.5 years to 7 years) which has improved confidence within the models and enabled inter-annual variability statistics to be included within the results. The wave resource assessment now includes statistics that differentiate between the energy that can be exploited by focusing a device on the primary component of energy in the wave field, as compared to the energy available to devices that can capture the total energy from sea-states comprising distinct windwave and swell components (crossed-seas). The tidal dataset benefits from improved model calibration and enhanced vertical data resolution provided by five independent layers of model outputs. The tidal current dataset also has an improved accuracy through the implementation of a new ocean turbulence model.

Data Licence Agreement

The following data licence superceeds the version found in the associated metadata of relevant datasets.

Data Licence: THIS IS A LICENCE AGREEMENT BETWEEN THE DEPARTMENT OF BUSINESS, ENTERPRISE AND REGULATORY REFORM (AS OF 03/10/2008 THIS IS THE DEPARTMENT OF ENERGY AND CLIMATE CHANGE, WHERE THE ENERGY GROUP NOW RESIDES) ("LICENSOR") AND YOU ("LICENSEE").

1. Grant of Licence.

1.1. By using the Data the Licensor grants you ("the Licensee") a non-exclusive, non-transferable limited licence to use the accompanying Atlas of UK Marine Renewable Energy Resources Data sets including without limitation the Met Office and Proudman Oceanographic Laboratory data forming part of the content, electronic documentation (if applicable) strictly in accordance with the terms and conditions of this Licence Agreement.

1.2. The Licensee must ensure that the copyright notice of the Licensor is duplicated as it appears in or on the Data on all authorised copies. The Licensee must not assign or transfer this Licence Agreement to any third party.

The Licensor expressly excludes liability for indirect, special, incidental or consequential loss or damage (including without limitation loss of profits or business) howsoever caused even if advised of the possibility of such damages. Notwithstanding the foregoing, in the event the Licensee incurs any liability whatsoever under this Licence Agreement, such liability is limited to the licence fee paid by the Licensee for the Data.

2. Ownership of the Data

If the Licensor notifies the Licensee of such termination, the Licensee shall comply with the provisions of this Licence Agreement.

2.3. The Crown owns the intellectual property rights in the Met Office and Proudman Oceanographic Laboratory Data which form part of the Data set. The Licensee shall not have any rights or interests in the Met Office or Proudman Oceanographic Laboratory Data other than as described in this Licence Agreement. The Met Office Data is derived from model output with the permission of the Controller of Her Majesty's Stationary Office © Crown copyright. The Proudman Oceanographic Laboratory Data is derived from model outputs with the permission of the Controller of Her Majesty's Stationary Office © Crown copyright. Unauthorised reproduction infringes Crown copyright and may lead to prosecution or civil proceedings.

Map Help

Most webGIS map processes are described in the Map Help, which is (only) available on each webGIS page and is accessed by either using the 'Map Help' link at the top of the page or by clicking on any of the help icons . On clicking help it will either open a new window or refocus an existing help window. Below is the contents list of the Map Help.

Querying the Data

Select cells by defining lower and upper range for a specific resource parameter combined with depth and distance from nearest land, see the table below.

Available Queries

Resource	Layer
Wave	Annual Mean Wave height (Hs)
	Annual Mean Wave Power (Optimal Device)
Tide	Mean Spring Peak Currents
	Annual Tidal Power
Wind	Annual Mean Wind Speed (100m)
	Annual Mean Wind Power (100m)

Running one of these queries will take the user entered values (or defaults) and then return all cells with attributes that meet those criteria.  The underlying logic of each of these queries can be summarised in the following statement:
