Details

Background

Land cover is the observed physical cover on the Earth’s surface including trees, shrubs, grasses, soils, exposed rocks, water bodies, plantations, crops and built structures. A consistent, Australia-wide land cover product helps understanding of how the different parts of the environment change and inter-relate. Earth observation data recorded over a period of time firstly allows the observation of the state of land cover at a specific time and secondly the way that land cover changes by comparison between times.

What this product offers

DEA Land Cover provides annual land cover classifications for Australia using the Food and Agriculture Organisation Land Cover Classification System taxonomy Version 2 (Di Gregorio and Jansen, 1998; 2005).

DEA Land Cover divides the landscape into six base land cover types, which are then further detailed through the addition of environmental descriptors. The structure is as follows:

Cultivated Terrestrial Vegetation
- percentage of cover
- life form (herbaceous only)
Natural Terrestrial Vegetation
- percentage of cover
- life form (woody or herbaceous)
Natural Aquatic Vegetation
- percentage of cover
- life form (woody or herbaceous)
- water seasonality
Artificial Surfaces
Natural Bare
- percentage of bare cover
Aquatic
- water persistence
- intertidal area

Applications

Annual Land Cover information can be used in a number of ways to support the monitoring and management of environments in Australia. These include, but are not limited to, the following areas in environmental monitoring, primary industries and the interests and safety of the Australian community:

Environmental monitoring
- Ecosystem mapping
- Carbon dynamics
- Erosion management
Agriculture Sector
- Monitoring crop responses to water availability
- Understanding drought impact on vegetation
Community interests
- Map urban expansion within Australia
- Mapping impacts of natural disasters
- Bushfire recovery

Technical information

DEA Land Cover is based on the globally applicable Food and Agriculture Organisation’s (FAO) Land Cover Classification System (LCCS) taxonomy Version 2 (Di Gregorio and Jansen, 1998; 2005). DEA Land Cover classifications have been generated by combining quantitative (continuous) or qualitative (thematic) environmental information (referred to as Essential Descriptors; EDs) derived from Landsat satellite sensor data. Several EDs have been generated previously by Geoscience Australia, including annual water summaries (Mueller et al., 2016), vegetation fractional cover (Scarth et al., 2010), mangrove extent (Lymburner et al., 2020) and the Inter Tidal Extent Model (ITEM; Sagar et al., 2017), whilst others have been developed more recently. These EDs have been combined to generate detailed, consistent and expandable annual classifications of Australia’s land cover from 1986 through to 2020.

DEA Land Cover consists of eight datasets: The base (level 3) classification, seven additional descriptor layers, and the final (level 4) classification combining the base classes with their associated descriptors.

Detailed layer descriptions, including known issues, are provided in the following sections.

Level 3 Class descriptions

Cultivated Terrestrial Vegetation (CTV)

Cultivated Terrestrial Vegetation (CTV) is associated with agricultural areas where active cultivation has been observed. In version 1.0 only herbaceous cultivation is shown and describes vegetation of strongly varying cover, ranging from bare (e.g. ploughed) areas to fully developed crops. Whilst the continental product describes land cover, interpretation is complicated as the same terminology is used to report on land use.

The definition of cultivated, and the difference to natural or semi-natural land covers, can be contentious particularly as much of the Australian landscape is used for agricultural food production. This includes areas of natural terrestrial vegetation (NTV) and natural aquatic vegetation (NAV) that are grazed by stock and which can be regarded as either semi-natural or cultivated.

CTV in the DEA Land Cover map is associated with areas where management practices aimed at cultivation (including for grass production) are actively performed during the year being shown. These practices include crop planting and harvesting, fertilization and ploughing. These practices often lead to highly dynamic spectral signals within and between years but also regular transitions between vegetation of different cover amounts as well as bare soil. This also means that agricultural areas will transition between natural and cultivated covers as management practices transition an area between actively cropped or grazed, to areas left fallow, areas reduced to low cover due to climate effects such as drought, or to other covers depending on what the predominant conditions are through the year being shown.

Natural Terrestrial Vegetation (NTV)

Natural Terrestrial Vegetation (NTV) represents areas that have all or most of the characteristics of natural or semi-natural herbaceous or woody vegetation (based primarily on floristics, structure, function and dynamics). These areas are identified as primarily vegetated, with either a photosynthetic vegetation fraction (PV) or non-photosynthetic fraction (NPV) greater than the bare soil fraction (BS) for at least two consecutive months. This approach considers that vegetation can exist in, and transition between, PV and NPV states during the year. In effect this approach classifies the landscape as primarily vegetated where the vegetated fraction of a pixel is greater than 30 %. Where the proportion of the landscape is under 30 % vegetated, it is regarded as sparsely vegetated or natural surface, but the cover proportions can still be quantified. Urban areas that are vegetated (e.g. suburbs with trees) are associated with NTV if the pixel is at least 30 % vegetated but artificial surfaces (AS) otherwise. The implementation allows areas of semi-natural vegetation (e.g. native grasslands/pastureland) to be included in the NTV class.

Natural Aquatic Vegetation (NAV)

Natural Aquatic Vegetation (NAV) is associated primarily with wetlands that are dominated by woody and/or herbaceous vegetation (as with NTV). NAV is generally associated with swamps, fens, flooded forests, saltmarshes or mangroves. Only mangroves are included in the current release.

Artificial Surfaces (AS)

Artificial Surfaces (AS) are areas of non-vegetated land cover created by human activities and are primarily represented by impervious surfaces (e.g. urban and industrial buildings, roads and railways). These can be more readily identified when the area is larger than the spatial resolution (25 m) provided by the sensor. Open cut extraction sites are often included in AS. However, there is considerable misclassification of NS as AS in areas where vegetated cover is very low and very consistent through the year.

Natural Surfaces (NS)

Natural Surfaces (NS) are comprised primarily of unconsolidated (often pervious, e.g. mudflats, saltpans) and/or consolidated (e.g. bare rock or bare soil) materials. In Australia, the proportional area of natural surfaces is relatively low and primarily confined to the deserts and semi-arid areas, river channels (e.g. dry riverbeds) and the coastline (e.g. sand dunes, mudflats). Much of the interior of Australia is sparsely vegetated and can be dominated by herbaceous (annual or perennial) or woody lifeforms.

Water

The Water class captures terrestrial and coastal open water such as dams, lakes, large rivers and the coastal and near-shore zone.

Lineage

The FAO LCCS taxonomy (Figure 1) is hierarchical and consists of a dichotomous phase (Level 1 to 3) and a modular phase (referred to as Level 4). In Level 1, vegetated and non-vegetated areas are first separated. These are then divided into terrestrial or aquatic categories to form Level 2. In the vegetated terrestrial category, cultivated and natural (including semi-natural) areas are differentiated. The non-vegetated category is further divided into artificial surfaces, and natural surfaces incorporating low vegetation cover and bare areas. Including the non-vegetated aquatic class (from Level 2), this results in the creation of six base land cover categories.

Figure 1 - Diagrammatic representation of the implementation of the FAO LCCS (Version 2) classification within the DEA Land Cover product version 1.0.

At Level 4, vegetated areas are further classified using information that differentiates lifeform (woody and herbaceous) and quantifies vegetation cover percent and water seasonality (for Natural Aquatic Vegetation). Natural Surface areas have information added (bare gradation) which describes the level of remaining vegetation present (sparse, very sparse or not detectable). Non-vegetated aquatic areas (Water) are further described on the basis of their persistence (hydroperiod) over a calendar year. The FAO LCCS differentiates water in different physical states (liquid or frozen; ice or snow), however only liquid water is included in the current release.

Quality

Accuracy

The product was validated using 6000 points spatially distributed over Australia. These points were created using a stratified random sampling approach slightly adjusted for oversampling. This process was conducted for 2010 and 2015 creating 12000 samples in total. After removing points with No Data and spurious values the total number was 11750. The sample points were divided into clusters for visual assessment against the outputs from the classification and assessed individually from a pool of 10 people. To compare the individual biases of the individual assessors, an additional set of validation points were created that all assessors evaluated, the results are shown in Table 4. Where assessors could identify a predominant land cover (i.e. not ‘mixed’ pixels or ‘unsure’), all assessors agreed 75 % of the time.

Table 2 contains the overall accuracy for all classes. The term ‘support’ refers to the number of validation points used in the calculation of that accuracy value.

Overall accuracy of DEA Land Cover is 80%. 2010 accuracy is 82%, 2015 accuracy is 78%.

Table 3 contains per-class accuracy information. “Precision” refers to the ability of a classification model to return only relevant instances. “Recall” refers to the ability to identify all relevant instances. The “F1 score” is a combination of precision and recall and an overall measure of accuracy. Classes such as artificial surfaces, natural aquatic vegetation and water had high accuracies. Classifying cultivated terrestrial vegetation and bare surfaces was challenging and accuracies were the lowest of the six classes presented here.

Limitations of the Implementation Method

DEA Land Cover is created by combining multiple layers that each describe features in the landscape. In doing so the extents of each layer do not necessarily completely align, and some no-data points can cross between outputs. As a result, there are some level 4 classes that only report detail to level 3 as the details of cover fraction and water persistence do not have corresponding data in the respective datasets. This specifically relates the classes of Water, NS and NAV in areas near water bodies and the intertidal zone, however the number of affected pixels is small.

Level 3 Class Limitations

Cultivated Terrestrial Vegetation (CTV)

Managed plantations and some orchards and tree crops are not currently distinguishable from semi-natural or natural terrestrial vegetation and are not yet incorporated in the area of CTV. Reference can be made to Australia’s National Plantation Inventory. In savanna regions (e.g. Queensland, Northern Territory and Western Australia), variable cycles associated with fires, inundation, drought and rainfall lead to greening or browning of natural vegetation that mirrors the seasonal or management-induced behavior of cultivated land. This leads to some areas of NTV, NS or NAV being misclassified as CTV. For example, the anomalous high levels of rainfall in 2010 led to vegetation growth patterns that were classified as cultivated vegetation, these false positives reduced the precision of the class in that year. Several natural vegetation types, particularly in the monsoonal north, are mapped as CTV due to burning, which can be associated with the indigenous management cycle. Saltmarsh and surface algae on mudflats can also be misclassified. Areas of bare soil exposed for long periods during the agricultural cycle or management activities, and sparse vegetation (when areas are not in use or fallow such as during drought periods) can be assigned as Natural Surfaces (NS). This is particularly the case where areas have experienced low cover for prolonged periods within a year.

Natural Terrestrial Vegetation (NTV)

The NTV category can transition into the NS category between years when a highly variable Landsat satellite spectral signature is observed due to changes in vegetation productivity and moisture content. The transition of NTV to NS is particularly evident when comparing periods with rainfall above (as in 2010) or below (e.g. drought; as in 2015) the average. Some confusion between surfaces that are primarily bare surfaces and non-photosynthetic vegetation remains and is also partly a function of the spectral reflectance of the underlying soil type. Vegetated areas shadowed by terrain can also be misclassified as non-vegetated. Areas of very low vegetation coverage are associated with the NS rather than NTV category, with the cover percentages shown as percentage bare. The assignment of vegetated suburbs to NTV is largely correct, but AS surfaces located beneath the canopy are not currently represented in the product. Some confusion between CTV and NTV can occur because of natural seasonal changes in native vegetation. The edges of salt lakes may be misclassified as NTV.

Natural Aquatic Vegetation (NAV)

Currently only mangroves are mapped in the NAV class. Other vegetated natural landscapes (e.g. saltmarsh, river red gum forests in the Murray Valley, surface algae and other inland wetlands) where water significantly influences edaphic conditions of substrate are not mapped. This is because, in the current implementation, the water mask is included to assist in the differentiation of vegetation and non-vegetation as the presence of water creates excess noise in the underlying Fractional Cover product. To reduce this noise, the WOfS product is used as a water mask in the Fractional Cover product, and hence it is unlikely to produce the combination of vegetation and water required for the NAV class.

Artificial Surfaces (AS)

Misclassification occurs with natural surfaces, particularly in the arid and semi-arid regions, open cut mine sites, salt lakes and pans, sand dunes and beaches. This is attributed to similarities in the variance of spectral signatures over a year. Misclassification occurs in some cultivated areas attributable to the predominance of sparse vegetation or when land is left fallow for most of the year. The current temporal variance mask is 250 m in spatial resolution, compared to the 25 m land cover product, resulting in artefacts appearing in the land cover from the masking process. In addition, urban areas with an area less than 250 m are often excluded. Cloud and data quality issues can lead to incorrect assignment of other land cover classes to AS such as in south-west Tasmania.

Natural Surfaces (NS)

Land used for agriculture may be associated with an NS class if ploughing or tillage has occurred and the vegetation cover remains low during the calendar year. Areas mapped as NS may, under certain circumstances (e.g. during drought) temporarily transition to or from CTV. This occurs because of the dominance of non-persistent vegetation (e.g. short crop life spans), desiccation, removal during dry periods or management practices (e.g. left as fallow). Where acquisition of cloud-free Landsat satellite sensor data has been infrequent, less information on the inter-annual variability of vegetation is provided. Where cloud cover is extensive (e.g. in Tasmania), the number of scenes for land cover classification is reduced and this can compromise classification of NS, particularly where bare surfaces alternate with vegetation. Confusion between natural surfaces and urban areas occurs because of similar spectral variation over an annual period.

Water

Areas of artificial and natural water are not differentiated, although the extent of the former is mapped within the existing Bureau of Meteorology Geofabric product. Due to the 25 m pixel size, rivers and water courses that cover less than a pixel, or with highly vegetated riverbanks are not captured, resulting in a patch-like representation of narrower rivers. Areas of dark, wet soil are often misclassified as water, including in cultivated areas and mud flats.

Earth Observation Limitations

To generate the land cover classification for each calendar year, annual (January – December) statistics derived from Landsat-5, -7 and -8 observations are currently used, with each satellite sensor potentially observing the Australian landscape every 16 days. This brings an intrinsic limitation to land cover mapping as persistent cloud in some regions reduces the number of useable observations. This is particularly evident in Tasmania, and northern Australia during the monsoon period, where areas may not be observed for extended periods and parts or all of the intra-annual land cover cycle may be missed. These limitations can lead to misclassifications of land cover, particularly in dynamic environments. In a future release, a confidence layer will be included to help identify areas with poor observation frequency or other factors impacting the classification.

An additional limitation of the Landsat series is the availability of data due to the ageing of each satellite. Landsat 5 was operational for over 25 years, but for much of the later years, data were only acquired when sunlight directly illuminated its solar panels. This limited its operation across Australia, with coverage being seasonally dependent, and contracting north to a minimum in winter. In its last years the winter coverage usually only covered the northern coasts of Australia. Landsat 5 ceased regular operations over Australia in 2011, leaving just Landsat 7 until Landsat 8 was launched in 2013. Landsat 7 began service in 1999 as a replacement for Landsat 5. Initially Landsat 5 was switched off, but when Landsat 7 suffered a serious problem in 2003 due to the failure of its scan-line corrector (termed SLC-Off) Landsat 5 resumed service. The SLC-Off failure of Landsat 7 results in severe striping across every image from mid 2003 onwards, apparent in subsequent derived products. Landsat 8 has operated well since launch in 2013, with improved sensitivity, noise characteristics and data correction in comparison to the earlier sensors.

The result of the availability of the satellites is that the most consistent data availability occurs when two satellites are in operation (most of the 2003 to present period). The least data availability is in 2011 – 2012 when only Landsat 7 was available with data containing the SLC-Off striping issue. The overall data availability for the Landsat satellites is shown in Table 5. The datasets used in this analysis are shown in Table 6.
