This map contains district-based ACT canopy cover polygons at 1m resolution (vegetation cover above 3m) as at April/May 2020, detected with Light Detection and Ranging (LiDAR). The full ACT vector dataset has been split into districts and 1km tiles to allow for easier viewing.WARNING: Due to complexity and high resolution this dataset may draw slowly or appear to miss some trees. For best results, zoom in, view single districts separately, or download a local copy.LIDAR data was acquired in April/May 2020 for the ACT under contract by Aerometrex, at an average resolution of 12ppm. LiDAR is classified to Level 3 (for ground) and delivered as LAS v1.4 in in GDA2020 MGA zone 55. Visit https://www.planning.act.gov.au/survey-spatial-data-and-maps/actmapi-and-spatial-data/lidar-data for more info. Processing was completed on the LAS GDA2020 MGA Zone 55 LAS tile set using AHD vertical datum at 1m resolution. Dataset represents high vegetation above 3m (tree canopy or tree-approximate objects - see caveats).Methodology:High noise errors were reclassified.Digital Surface Model (DSM) and Digital Elevation Model (DEM) surfaces were created using ArcPro 2.8 LAS Dataset Geoprocessing Tools at 1 m resolution.Canopy Height Model CHM was determined = Digital Surface Model (DSM) - Digital Elevation Model (DEM).Pits (empty cells inside tree canopies) of 2 pixel (2x1m) were removed using Nibble.An ACT Urban building footprint layer generated from the 2020 LIDAR dataset by Aerometrex was used to remove spurious canopy portions from building roof areas in the urban area.An NDVI layer from pan-sharpened Pleiades multispectral satellite imagery, acquired in April 2019 (the Uriarra area) and November 2019 (rest of Urban Area) was used to delete erroneous non-vegetative surfaces in urban areas.Canopy holes <=1m2 were filled by Eliminate tool.GDA2020 MGA Zone 55.Tree canopy lower than 3m were removed. Converted to a binary raster, then converted to vector.Other available datasets: ACT 2020 Canopy Height Model (raster), ACT Trees (Individual Delineated Trees with Height) (vector), DEM, DSM, Contours, Building Footprints (© Australian Capital Territory & Aerometrex Limited), ACT Permeability, shrub cover - contact spatialdata@act.gov.au.

Please note that most (if not all) CHM-based tree delineation results should be thought of as "tree-approximate objects", and not actual trees. 2. Although every effort was made to remove any erroneous polygons (such as street lights, back yard fences and powerlines), there are likely to be some errors remaining.Creative Commons by Attribution (CCBY) 4.0 (Australian Capital Territory).

This imagery tile cache is a mash up of multiple imagery captures that provide complete ACT coverage. Source imagery is captured and provided by MetroMap. Urban area and western edge of ACT imagery captured 5 - 12 May 2023. Remaining rural imagery captured on 27 - 28 December 2022. It is suitable for use as a base map or map layer, and may be taken offline. It is used in the ACTmapi web applications and has been created to provide general access to imagery previously provided by ACTmapi data4 services

A parcel of land, usually the smallest unit of land that can be held under an individual lease without a requirement for further subdivision. Blocks in ACTMAPi are displayed as Urban and Rural blocks, and have been separated into individual layers based on its lifecycle stage (Registered, Approved, Proposed, Occupied and Retired). URBAN blocks are defined as blocks that appear within a division and have division and section identifiers. RURAL blocks do not usually appear within a division, but may do so if they remain from before the division was created. REGISTERED: The block appears on a Deposited Plan that has been registered with the Land Titles Office but is not RETIRED or DELETED. APPROVED: The block appears on an Approved Plan that has been signed by the Territory Planning Section and the Project Officer for the development, but the block is not REGISTERED, RETIRED or DELETED. PROPOSED: The block is proposed but has not reached any other stage. OCCUPIED: The block is leased, but does not appear on a registered plan. Leases over unregistered blocks may not be registered at the Land Titles Office, so this stage is used for unregistered blocks with unregistered leases. This normally only occurs in rural areas. RETIRED: Retirement of a block occurs when it is replaced by another block.

Coordinate System is MGA2020-55 (EPSG #7855). The physical boundary between two road reserve segments that prevents vehicular access; or the boundary of applicability of a road name between two road reserve segments that do not belong to the same road where one road runs into another (and hence there is no physical boundary or indication). The type of physical boundary relevant in each case is defined by the VEHICLE_RESTRICTION_FLAG attribute. A value of 0 is "Unrestricted Delimeter" and 1 is "Restricted R-Section".

ACT Canopy Estimate Statistics 2020 for blocks, divisions and road polygons are derived from the ACT Canopy Cover 2020 footprint dataset (available soon). The canopy dataset is derived from LiDAR (Light Detection and Ranging) data captured by Aerometrex and the ACT Government (available here) at 12ppm over the ACT and region in April 2020. This datasets provides the estimated % coverage of vegetation above 3m for blocks, division and road polygons current at 2021, and was completed by a collaboration between EPSDD and TCCS, ACT Government. The canopy coverage % is determined by the coverage of vegetation above 3m divided by the area of feature (e.g. block area). The total tree canopy cover estimate for Canberra for 2020 is based on the footprint of all urban divisions (suburbs): 22.5%.

The ACT 2020 LiDAR point clouds (Aerometrex and ACT Government 2020) are available from https://elevation.fsdf.org.au/ (CCBY Licence).Data lineage: This dataset is derived from the Light Detection and Ranging (LiDAR) data captured by Aerometrex and ACT Government over ACT in April 2020. The point clouds were processed by the ACT Government with ArcGIS to produce ACT Canopy Cover footprint for vegetation above 3m. Canopy modelling was completed at 1m resolution. The canopy footprints were then augmented to block, division and road polygon coverage statistics.Coordinate system: GDA 2020 MGA Zone 55.Temporal coverage: April 2020Update schedule: every 5 yearsTile photo by Mark Jekabsons, Trees over GungahlinCaveat: Comparison of the ACT 2020 Canopy Cover to the 2015 is not comparable due to differences in methodology, including differences in resolution and point density, and time of year the LiDAR was captured. The 2015 data was captured in late Autumn, whereas 2020 was captured in early Autumn.

The ACT Districts Boundaries are a region defined for land administration and the legal description of land parcels. In urban areas districts contain divisions, sections and blocks. In rural areas they contain blocks only. The boundaries of districts are defined in metres and bounds form in the Districts Act 1966, and thus cannot be changed without changes to the legislation. A district may contain a number of divisions; however some divisions may be in two districts (e.g.Red Hill)

The geocoded addressing data maintained by Environment, Planning and Sustainable Development is the authoritative source for addressing in the ACT. The geocoded address provides the spatial location of the address (point) and the conventional description of a block or group of blocks in the ACT generally consisting of a street number, street name, division (urban only) and district. Addressing data is maintained on a daily basis as addresses are allocated resulting from Development Applications (DA), Estate Development Plans (EDP) or residential requests. Each block may have many addresses and an address may cover many blocks. One urban block may have more than one address if there are several street frontages, or if it is a unit development or a dual occupancy. The ACT Government maintains property street address details under the Districts Act 2002. Information is captured for both urban and rural properties. This dataset includes only assigned addresses.
