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

A council development plan may designate a green belt around a city or town to support the spatial strategy by: - directing development to the most appropriate locations and supporting regeneration; - protecting and enhancing the character, landscape setting and identity of the settlement; and - protecting and providing access to open space. This dataset has been developed as a polygon layer.

The G-BASE programme involves systematic sampling and the determination of chemical elements in samples of stream sediment, stream water and soil, to build up a picture of the surface chemistry of the UK. The average sample density for stream sediments and water is about one site per 1.5-2km square, and for soils one site per 2km square. Analytical precision is high with strict quality control to ensure countrywide consistency. Results have been standardised to ensure seamless joins between geochemical sampling campaigns. The data provide baseline information on the natural abundances of elements, against which anomalous values due to such factors as mineralisation and industrial contamination may be compared. Analytical data for the 150 microns fraction of soil and stream sediment samples are available for some or all of: Ag, As, B, Ba, Bi, Be, Ca, Ce, Cd, Co, Cr, Cs, Cu, Fe, Ga, K, La, Li, Mg, Mn, Mo, Nb, Ni, P, Pb, Rb, Sb, Se, Sn, Sr, Th, Ti, U, V, Y, Zn, and Zr. Most water samples have been analysed for alkalinity, pH, conductivity, F and U and some for multi-element analyses including Al, Cl, Na, Si, SO4,NO4, and TOC. The project now routinely determines the elements listed in the <2mm fraction of surface soils.

The annually binned Sea Surface Salinity, Temperature and Density data set covers a large part of the North Atlantic subpolar gyre. It is based on T and S near-surface data collected since December 1895 to August 2018 from all data sources, including Voluntary Observing Ships subsequently validated. This annual product presents deviations from a climatological seasonal cycle and has furthermore been smoothed in time with a 1/4, 1/2, 1/4 running-mean filter. Density time series are estimated from those annual time series, considering winter (D-J-F) climatology. Uncertainty estimates due to sampling are also provided. Data for December 2017-August 2018 are also reported as 2018, but are temporary and should not be used without further check. Long gaps have been filled by linear interpolation, and are attributed largest error.

Sea Surface Salinity (SSS) is an essential climate variable that requires long term in situ observation. The French SSS Observation Service (SSS-OS) manages a network of Voluntary Observing Ships equipped with thermosalinographs (TSG) since 2002. The network is global though more concentrated in the tropical Pacific and North Atlantic oceanic basins. The acquisition system is autonomous with real time transmission and is regularly serviced at harbor calls. The high resolution data retrieved from the acquisition system during ship calls is processed through a dedicated software (freely available) for attribution of data quality flags by visual inspection, and correction of TSG time series by comparison with climatology, onboard daily water samples and collocated Argo data. Details can be found in the reference below. The validated delayed time data collected from TSG, together with some bucket samples mostly collected before 2002, are made available for educational and research purposes through an interactive web interface.

Landings by live weight (tonnes) for commercial fishing activity in Scottish seas of demersal (bottom dwelling) fish species, including UK registered fishing vessels wherever they land and non-UK vessels if landing into the UK, as recorded in last five years of published statistics. Data is redacted if less than five vessels operate within an ICES statistical rectangle (values = -1).

First sales (£GBP) from commercial fishing activity in Scottish seas of shellfish (crustacean/mollusc) species, including UK registered fishing vessels wherever they land and non-UK vessels if landing into the UK, as recorded in last five years of published statistics. Data is redacted if less than five vessels operate within an ICES statistical rectangle (values = -1).

All effective and non effective housing sites from Dundee City Council Housing Land Audit have been spatially recorded since 1997. The Housing Land Audit (HLA) provides a factual statement of land supply of housing sites with a capacity of 5 units or more.Sites with less than 5 units are still recorded and added as an aggregate to the total Housing Land Audit supply.'Effective' sites are those which Dundee City Council expect to be developed within the next five years from date of application. Effective sites also include those allocated within the Local Development Plan (LDP).

First sales (£GBP) from commercial fishing activity in Scottish seas of pelagic (midwater/oceanic) fish species, including UK registered fishing vessels wherever they land and non-UK vessels if landing into the UK, as recorded in last five years of published statistics. Data is redacted if less than five vessels operate within an ICES statistical rectangle (values = -1).

The Scottish Vacant and Derelict Land Survey is a national data collection undertaken to establish the extent and state of vacant and derelict land in Scotland. The survey has been operating since 1988. This survey is associated with the Scottish Vacant and Derelict Land Fund, under which cash allocations are made to local authorities. Every year the Scottish Government Communities Analytical Services produce a comprehensive national survey based on data collected and processed from all Local Authorities and Loch Lomond and Trossachs National Park Authority. The Spatial Hub takes this survey data and joins it (using site ID) to the polygon site information provided by local authorities. To create this dataset we have taken all of the spatial data provided by councils for the current survey year (2018 published in 2019) and combined it to this year's statistical survey (using the site reference). However: - where local authorities have not provided spatial data for the current year, their previous spatial data return has been used. - where there is no spatial data at all for sites we have buffered the easting and northing provided in the survey, to create a circular polygon area for a site.
