ACTmapi - ACTGOV BLOCK
공공데이터포털
The position and extents of a parcel of land, usually the smallest unit of land that can be held under an individual lease without a requirement for further subdivision. 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. Blocks may have a lifecycle stage or Proposed, Registered, Approved, Occupied or Retired.PROPOSED: The block is proposed but has not reached any other stage.REGISTERED: The block appears on a Deposited Plan that has been registered with the Land Titles Office.APPROVED: The block appears on an Approved Plan that has been signed by the Territory Planning Section and the Project Officer for the development.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.Note that block boundaries may not always align exactly. The legal definition of a block is defined in the Deposited plan.

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.

Census Blocks 2020
공공데이터포털
Census Blocks are statistical areas bounded on all sides by visible features, such as streets, roads, streams, and railroad tracks, and/or by nonvisible boundaries such as city, town, township, and county limits, and short line-of-sight extensions of streets and roads. Census blocks are relatively small in area; for example, a block in a city bounded by streets. However, census blocks in remote areas are often large and irregular and may even be many square miles in area. A common misunderstanding is that data users think census blocks are used geographically to build all other census geographic areas, rather all other census geographic areas are updated and then used as the primary constraints, along with roads and water features, to delineate the tabulation blocks. As a result, all 2020 Census blocks nest within every other 2020 Census geographic area, so that Census Bureau statistical data can be tabulated at the block level and aggregated up to the appropriate geographic areas. Blocks are the smallest geographic areas for which the Census Bureau publishes data from the decennial census.

A. SUMMARY Census blocks, the smallest geographic area for which the Bureau of the Census collects and tabulates decennial census data, are formed by streets, roads, railroads, streams and other bodies of water, other visible physical and cultural features, and the legal boundaries shown on Census Bureau maps. More information on the census tracts can be found here. B. HOW THE DATASET IS CREATED The boundaries are uploaded from TIGER/Line shapefiles provided by the U.S. Census Bureau. C. UPDATE PROCESS This dataset is static. Changes to the census blocks are tracked in multiple datasets. See here for 2000 and 2010 census tract boundaries. D. HOW TO USE THIS DATASET This boundary file can be joined to other census datasets on GEOID. Column descriptions can be found on in the technical documentation included on the census.gov website E.
