    ScotMap is a Marine Scotland project which provides spatial information on the fishing activity of Scottish registered commercial fishing vessels under 15 m in overall length. The data were collected during face-to-face interview with individual vessel owners and operators and relate to fishing activity for the period 2007 to 2011. The data are aggregated and analysed to provide information on the monetary value, relative importance (relative value) and the usage (number of fishing vessels and crew) of seas around Scotland.

    The requirement to display sensitive areas relating to the life history of commercially important fish species in British waters is well recognized. Sensitive areas have previously been described as spawning and nursery grounds. Here we consider only areas where there is evidence of aggregations of 0 group fish and/or larvae of key commercial species. 0 group fish are defined as fish in the first year of their lives. These fish sensitivity maps were originally generated to provide a spatial and temporal description of where physical damage could potentially occur to fish species at sensitive stages in essential habitats of their life cycle. Sources of damage in this context referred to seismic surveying conducted by the offshore Oil and Gas industry during their site investigations. In addition to the acoustic energy that the seismic survey activities generate, we should now add other percussive impact noises from pile driving seabed foundation pins into the seabed, such as those required for offshore renewable energy sites. The spatial location of these fish life history events and their potential interaction with offshore industries can heavily influence the planning, costs and delivery of these offshore developments. It is imperative that these maps reflect the current extent of these areas.

    High resolution bathymetry data of Rockall and Helen's Reef collected 2011-2012 as part of the ROAME Offshore Fisheries and Conservation (OFFCON) project. Rockall, a tiny island just 19 metres high, sits on the very extremity of Scotland’s marine environment. Some 180 miles due west of St. Kilda, it is buffeted year round by the extreme winds and swell that the North Atlantic weather generates. As such, it is Scotland’s only truly offshore shallow water ecosystem. The islet of Rockall is actually the only part of vast plateau of submerged continent that remains above sea-level.

    This is a Scotland raster based (10m) landcover made up of best available national data classified according to the EUNIS (EUropean Nature Information System). The main purpose of the landcover is to provide well-known, nationally consistent information for SNH’s national habitat network models. Secondary purposes include input for other analysis projects as well as map backdrops.

    One of four component layer of the Scottish wildness map. This layer seeks to capture ruggedness: 'landform which is rugged, or otherwise physically challenging' (Annex 1 SNH policy statement). The dataset is on a scale of 1-256 indicating relative levels of ruggedness. Consequently the data is best viewed at a national or regional scale. The methodology is adapted from the 2008 Wildness Study in the Cairngorms National Park.

    The Scottish Public Sector LiDAR (Phase I) dataset was commissioned in response to the Flood Risk Management Act (2009) by the Scottish Government, Scottish Environmental Protection Agency (SEPA), and Scottish Water collaboratively. Airborne LiDAR data was collected across 10 sites totalling 11,845 km2 (note the dataset does not have full national coverage) between March 2011 and May 2012. Aside from flood risk management, this data has also been used for archaeological and orienteering purposes. This dataset reflects the Digital Surface Model (DSM) produced from the point cloud data.

    The Scottish Public Sector LiDAR (Phase II) dataset was commissioned in response to the Flood Risk Management Act (2009) by the Scottish Government, Scottish Environmental Protection Agency (SEPA), sportscotland, and 13 Scottish local authorities. This extension of the Phase I dataset collected airborne LiDAR for 66 additional sites for the purposes of localised flood management. Data was collected between 29th November 2012 and 18th April 2014 totalling an area of 3,516 km2 (note the dataset does not have full national coverage). Aside from flood risk management, this data has also been used for archaeological and orienteering purposes. This dataset reflects the Digital Terrain Model (DTM) produced from the point cloud data.

    The heat demand is an amalgamation of a number of different spatial datasets that have associated heat demand values. The map has been developed on the principle of applying data with increasing levels of certainty and overlaying and replacing individual property heat demand values. The heat demand layer is made up of a number of rasters which depict this demand in different ways. The heat demand rasters present a visualisation of the heat demand density by showing total demand within grid squares. These are shown at various grid sizes (50x50, 250x250, 500x500 and 1000x1000). The Scotland Heat Map is supported by a number of documents including users guidance which is available at http://www.scotland.gov.uk/heatmap 2.1 Methodology report 2.2 Manual 2.3 Metadata 2.4 Local knowledge validation & improvement process 2.5 Data management 2.6 Limitations and protections for data use and analysis 2.7 Scotland heat map – interactive and local web
