West Hebrides Biotope Mapping Project
This project attempts to map the broadscale biotopes and habitats of the rocky reef sites west of the Outer Hebrides through integrating multibeam echosounder data, acoustic ground discrimination system (AGDS) data, underwater video/camera surveys and grab data, facilitated through the use of GIS. Where possible, biotopes have been resolved and classified using the National Marine Habitat Classification for Britain and Ireland (Connor et al., 2004).

RemoteTechnique
- Evaluation method description
-
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
Completeness commission
- Name of measure
-
RemoteCoverage
- Evaluation method description
-
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
- Evaluation method description
-
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
Topological consistency
- Name of measure
-
RemoteStdsApplied
- Evaluation method description
-
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

An indication of the age of the remote data:3 = < 5yrs old.2 = 5 to 10 yrs old.1 = > 10 years old

BGTTechnique
- Evaluation method description
-
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)
Non quantitative attribute accuracy

-
PGTTechnique
- Evaluation method description
-
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)

GTDensity
- Evaluation method description
-
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)

RemoteInterpretation
- Evaluation method description
-
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.
