RemoteTechnique
An assessment of whether the remote techniques used to produce this map were appropriate to the environment they were used to survey: 3 = technique(s) highly appropriate 2 = technique(s) moderately appropriate 1 = technique(s) inappropriate
RemoteCoverage
An assessment of the coverage of the remote sensing data including consideration of heterogeneity of the seabed: (See Coverage X Heterogeneity matrix below) Coverage scores - use these to determine coverage then combine with heterogeneity assessment to derive finale scores3 = good coverage; 100% (or greater) coverage or AGDS track spacing <50m2 = moderate coverage; swath approx 50% coverage or AGDS track spacing >100m1 = poor coverage; large gaps between swaths or AGDS track spacing > 100mFinal scores3 = good coverage OR moderate coverage + low heterogeneity2 = moderate coverage + moderate heterogeneity OR poor coverage + low heterogeneity 1 = moderate coverage + high heterogeneity OR poor coverage + moderate or high heterogeneity
RemotePositioning
An indication of the positioning method used for the remote data:3 = differential GPS2 = GPS (not differential) or other non-satellite 'electronic' navigation system1 = chart based navigation, or dead-reckoning
RemoteStdsApplied
An assessment of whether standards have been applied to the collection of the remote data. This field gives an indication of whether some data quality control has been carried out:3 = remote data collected to approved standards2 = remote data collected to ?internal? standards1 = no standards applied to the collection of the remote data
RemoteVintage
An indication of the age of the remote data:3 = < 5yrs old.2 = 5 to 10 yrs old.1 = > 10 years old
BGTTechnique
An assessment of whether the ground-truthing techniques used to produce this map were appropriate to the environment they were used to survey. Use scores for soft or hard substrata as appropriate to the area surveyed.Soft substrata predominate (i.e. those having infauna and epifauna)3 = infauna AND epifauna sampled AND observed (video/stills, direct human observation)2= infauna AND epifauna sampled, but NOT observed (video/stills, direct human observation)1 = infauna OR epifauna sampled, but not both. No observation.Hard substrata predominate (i.e. those with no infauna)3 = sampling included direct human observation (shore survey or diver survey)2 = sampling included video or stills but NO direct human observation1 = benthic sampling only (e.g. grabs, trawls)
PGTTechnique
An assessment of whether the combination of geophysical sampling techniques were appropriate to the environment they were used to survey. Use scores for soft or hard substrata as appropriate to the area surveyed.Soft substrata predominate (i.e. gravel, sand, mud)3 = full geophysical analysis (i.e. granulometry and/or geophysical testing (penetrometry, shear strenght etc))2 = sediments described following visual inspection of grab or core samples (e.g. slightly shelly, muddy sand)1 = sediments described on the basis of remote observation (by camera).Hard substrata predominate (i.e. rock outcrops, boulders, cobbles)3 = sampling included in-situ, direct human observation (shore survey or diver survey)2 = sampling included video or photographic observation, but NO in-situ, direct human observation1 = samples obtained only by rock dredge (or similar)
GTPositioning
An indication of the positioning method used for the ground-truth data:3 = differential GPS2 = GPS (not differential) or other non-satellite 'electronic' navigation system1 = chart based navigation, or dead-reckoning
GTDensity
An assessment of what proportion of the polygons or classes (groups of polygons with the same ?habitat? attribute) actually contain ground-truth data:3 = Every class in the map classification was sampled at least 3 times2 = Every class in the map classification was sampled1 = Not all classes in the map classification were sampled (some classes have no ground-truth data)
GTStdsApplied
An assessment of whether standards have been applied to the collection of the ground-truth data. This field gives an indication of whether some data quality control has been carried out:3 = ground-truth samples collected to approved standards2 = ground-truth samples collected to 'internal' standards1 = no standards applied to the collection of ground-truth samples
GTVintage
An indication of the age of the ground-truth data:3 = < 5 yrs old2 = 5 to 10 yrs old1 = > 10 years old
GTInterpretation
An indication of the confidence in the biological interpretation of the ground-truthing data:3 = Evidence of expert interpretation; full descriptions and taxon list provided for each habitat class2 = Evidence of expert interpretation, but no detailed description or taxon list supplied for each habitat class1 = No evidence of expert interpretation; limited descriptions available
RemoteInterpretation
An indication of the confidence in the interpretation of the remotely sensed data:3 = Appropriate technique used and documentation provided2 = Appropriate technique used but no documentation provided1 = Inappropriate technique usedNote that interpretation techniques can range from ?by eye? digitising of side scan by experts to statistical classification techniques.
DetailLevel
The level of detail to which the 'habitat' classes in the map have been classified:3 = Classes defined on the basis of detailed biological analysis2 = Classes defined on the basis of major characterising species or lifeforms1 = Classes defined on the basis of physical information, or broad biological zones
MapAccuracy
A test of the accuracy of the map:3 = high accuracy, proven by external accuracy assessment2 = high accuracy, proven by internal accuracy assessment1 = low accuracy, proved by either external or internal assessment OR no accuracy assessment made
