Canada Land Use Monitoring Program (CLUMP) Urban Land Use - 1966 to 1976Entry ID: Canada_GeoGratis_CLUMP
Abstract: The Canada Land Use Monitoring Program (CLUMP) was established in 1978 by the
Lands Directorate of Environment Canada to provide researchers, planners and
managers with a database on land use change. The program complemented the land
capability and land use surveys of the Canada Land Inventory (CLI). However,
most data sets associated with CLUMP were compiled at a higher ... level of detail
than the CLI.
Designed to monitor both spatially and sequentially land use change in
various areas of Canada, the CLUMP program had the following objectives:
1) to provide improved awareness of the state of the land resource.
2) to identify land use trends of national and regional importance.
3) to determine major areas of rapid change that could potentially
create land use problems.
4) to analyze land use change in terms of causes and consequences,
particularly with respect to the impact of government policies and programs.
The four major components of the CLUMP program were urban-centered
regions, prime resource lands, rural areas and wildlands. The Urban-Centered
Region (UCR) component (the component presented here) examined land use in the
rural-urban fringe of major Canadian urban centers.
The UCR program was coordinated nationally but undertaken through the
five regional offices of the Lands Directorate. Information on land use change
was originally classified according to the CLI land use scheme and applied at a
scale of 1:50,000. Interpretation consisted of mapping from aerial photographs
augmented with field checks and supplementary information sources such as
municipal planning maps, street maps and satellite images. Maps were scanned
and attribute data entered into the Canada Geographic Information System, a
pioneer computerized map storage, analysis and retrieval system.
The CLUMP UCR program operated from 1966 through to 1986 on a 5-year
basis corresponding to Canada's census years. In 1981 the original CLI based
land use classification was replaced in favor of a more comprehensive land
activity and land cover classification scheme. The UCR program was abandoned
after that. Nevertheless Canada's largest urban centers were mapped in every
There are two main data collections as a result of this UCR
sub-program: the CLUMP 1966-1976 cycle and the CLUMP 1981-1986 cycle; this
metadata entry is only for the earlier 1966, 1971 and 1976 cycle.
CLUMP UCR 1966-1971 data represents a relatively simple,
CLI-compatible set of land use and land cover classes applied to Canada's 23
largest urban areas. It is distributed through the GeoGratis site on the basis
of an "urban-centered region" (UCR). A UCR is delimited by the original CLUMP
program boundaries defined for each urban center. These urban limits should not
be interpreted as administrative, census or otherwise legal limits of an urban
area; they are merely the extent of the mapping.
In addition to the UCR land use centers are detailed maps of
agricultural and recreational land capability. These were originally compiled
at a scale of 1:50,000 but are aggregated to map sheet boundaries that extend
beyond the UCR limits. These CLI data can be used for analytical purposes with
or without the land use data.
OTHER TECHNICAL NOTES
- Three of the Urban Centers (St. John, N.B., Calgary and Edmonton)
span more than one UTM zone; these centers were assigned to the UTM zone in
which most of the study area occurs.
- The white surround has not been removed on the quicklook GIF files.
This is to ensure that all GIF files are the same size regardless of the
spatial extent of the UCR. The GIF files incorporate a browser-safe color
- The GIF files and WMF files use the same color palette and attribute
definitions of the respective Canada Land Inventory themes; if need be, the
same Canada Land Inventory HTML legend files can be utilized.
