Description
This polygon spatial dataset provides information on the land types of Maryvale Station, Northern Territory at a scale of 1:100,000. The survey area of 3,257 km2 is located approximately 100km south of Alice Springs via the Stuart Highway.
The Land Type descriptions were hand written during a land resource survey of Maryvale Station in the early 1980s, probably at a similar time a land resource survey was undertaken on the adjoining Orange Creek Station. The descriptions are the only information currently available. It is unknown whether the descriptions were draft or finalised. Given no site soil-landscape or vegetation field records from this survey have been located, and a technical report was not published, it should be assumed the information is DRAFT. The Maryvale Station land type descriptions only contain short geological and geomorphic descriptions.
Given no site soil-landscape or vegetation field records from this survey have been located, the land types should be verified with a field investigation if a high level of confidence is required.

Data Quality
Lineage:Original map unit boundaries delineated from aerial photographs and stereoscope interpretation. Map units transferred to clean dyeline sheets or topographic maps via a mapograph. Original maps were hardcopy only. With the advent of geographic information systems polygons were digitised by rectifying the original hard copy maps.
Map unit boundaries derived using hard copy aerial photography and stereoscope, satellite imagery (post 1993), geological and topographic maps. Field data (site data) described and classified according to national standards at the time of capture.
August 2021 - Additional data descriptions sourced from the hand-written notes were added to the spatial dataset. A map product was created to display the land types.
Positional Accuracy:POLYGON DATA
Hardcopy maps rectified using control points marked on original hardcopy maps. Control points include creek lines, cadastre and other topographic features. Depending on the nature of the landscape (the number of control points) positional accuracy may vary. Positional accuracy generally considered moderate.
POINT DATA
Survey teams navigated during field operations with topographic maps, aerial photographs and prismatic compass's. Point source locations marked on aerial photography in the field. Positional accuracy considered within 300m but generally below 200m depending on the terrain. Site coordinates derived by transferring site locations from aerial photographs to topographic maps and coordinates calculated. In some cases sites have been georeferenced directly from aerial photography to Google Earth Web Map Server in MapInfo or ArcGIS.
Attribute Accuracy:Given no site soil-landscape or vegetation field records from this survey have been located; the land types should be verified with a field investigation if a high level of confidence is required.
Logical Consistency:Polygons have been checked against satellite imagery and a hand-drawn map. There are no gaps, overlaps or slivers and all polygons have labels.
Completeness:Complete according to available information.

Data Dictionary
Attribute Attribute Description Possible Code Code Description 01. SURVEY_NME Alias: Survey Name
The name of the survey area or report to which the mapping refers02. SURVEY_ID Alias: Survey Identifier
A department code that usually refers to the first five characters from the original survey site sheet.03. LANDUNIT Alias: Land Unit
The LAND_UNIT field is the land unit label from the spatial dataset (ie 2.b).
Double or Triple labelled units: 'It should be noted that in a number of instances mapping scale has not allowed for the separation of discrete units. In these situations the dominant unit is shown above the minor one on the map e.g. 2.b./2a or 2.b/2.c. ' (Torlach 1983. Orange Creek report p.22)
04. DOM_LU Alias: Dominant land unit
eg Land unit is 4.1a/4.1b, therefore the dominant land unit is 4.1a05. LF_CLASS The landform class categorises the land unit using the dominant landform. 06. LANDTYPE The Land Type provides information about the dominant landform, geology and geomorphic descriptions. 07. UNIT_DESC The Land unit description provides additional details. 08. AREA_HA The area of each polygon has been calculated using units of hectares.
