Description:
Abstract:
Western Washington Land Use for 2004. Land use was calculated from LANDSAT imagery classification and spatial logic.
Purpose:
Calculate and display land use change on non-federal lands in Western Washington, using time- and cost-efficient remote sensing and GIS technologies, keeping in mind the following:

1) Develop methods that can be easily replicated for other areas of the Pacific Northwest;

2) And, attempt to exceed the accuracy and efficiency of conducting a similar study based on aerial photointerpretation, which is often costly and time-consuming.

Land cover is the observed (bio)physical cover on the Earth's surface, while land use is the use is what the land is used for by humans (e.g. protected areas, timber land, etc.). While land cover allows us to see overall biophysical cover, land use allows us to see patterns of development, management practices, and more.

Due to the temporal range of the data land use classifications were not tested or verified. Land use classifications were based entirely on the land cover classifications, spatial rules and land use definitions.

Due to the temporal range of the data land cover classifications were not tested or verified. Training datasets for the land cover classifications were developed from the original Landsat imagery by visual inspection. Overlapping classified Landsat scenes were used to calcualte a correlation metric for each time period. Agreement between land cover classes can be seen in the table below.

Unknown. Horizontal accuracy was not tested. Original terrain corrected Landsat L1G data has a stated accuracy of 250 meters. Co-registration, shifting and resampling of the images occurred to align the images from year to year. Land cover classification, geoprocessing elimination of small polygons and other spatial overlay decrease the accuracy even further. The suggested minimum mapping unit of this data is 25 hectares corresponding to a horizontal accuracy of 500 meters.

Land Cover Classifications

In addition to the Landsat imagery, two datasets were used in eCognition to assist in object segmentation and classification. Delineated floodplains and elevation bands were used to differentiate between irrigated agricultural lands and light forest cover, regeneration harvests and bare agricultural soils. Two segmentation levels were used to differentiate between large areas of relatively homogeneous land cover and small areas of development. This resulted in two different land cover classifications: a general land cover classification (i.e. forest or irrigated lands) and a developed (i.e. concrete, rooftops) land cover classification.

1. Dark Forest: Mature evergreen forest cover 2. Light Forest: Sub-mature and deciduous forest cover with increasing likelihood away from floodplains and in higher elevations 3. Regeneration: Bare or nearly bare soil with increasing likelihood away from floodplains and in higher elevations 4. Irrigated: Irrigated agricultural lands with increasing likelihood in or near floodplains and in lower elevations 5. Soil: Bare soil with increasing likelihood in or near floodplains and in lower elevations 6. Mixed Ag/Soil: Heterogeneous lands with some irrigated agricultural and bare soil often with some dispersed development 7. Residential: Low to medium density residential developments including rural developments and large-lot urban residential areas 8. Urban: Dense residential developments, urban centers and industrial lands 9. Water: Oceans, lakes, streams and reservoirs, etc… 10. Haze: Clouds partially block view of earth surface 11. Clouds: Clouds completely block view of earth surface 12. Shadow: Dark areas adjacent to Clouds 13. Unclassified: Spectrally indistinguishable areas which can not be classified 14. Built: Impervious surfaces, such as concrete, rooftops, gravel (classified at the fine-scale segmentation level)

Land Cover Classification Groups

Land cover was grouped by land cover classifications for calculation of contiguous land cover classification acres.

1. Forest: Dark Forest, Light Forest and Regeneration land cover classes 2. Agriculture: Irrigated, Soil and Mixed/Ag Soil land cover classes 3. Developed: Residential and Urban land cover classes 4. Clouds: Cloud land cover class 5. Shadow: Shadow land cover class 6. Unclassified: Unclassified land cover class

Land Use Polygons

Land use polygons were generated from the eCognition coarse scale image objects by dissolving objects less than 10 acres in size and not classified as water. While any minimum mapping unit could have been used it would have been difficult if not impossible to classify land uses in areas less than 10 acres (~7 x 7 pixels) with the resolution of the Landsat imagery. Land use polygon acres were calculated as a metric for calculating land use.

Percent Developed

The percent developed is the amount of concrete or other developed land cover that is within each land use polygon. The percentage developed of each land use polygon was calculated by overlaying the fine scale developed land cover classification on the dissolved coarse scale general land cover classification.

Development Density

Development density is the number of individual developments per square mile. The fine scale developed land cover classification was grouped into individual developments. Developments could be of any size ranging from approximately ¼ acre to 169,000 acres in the Seattle metropolitan area. The number of these unique developments in each land use polygon was normalized to a per square mile development density figure.

Land Use Trajectories

To decrease the likelihood of misclassification, land use trajectories were developed to create allowable land use change vectors. The primary assumption is that land can only proceed from a more wild to less wild condition. There is evidence that some agricultural lands have been forested and therefore gone to a "more wild" land use but this is believed to be rare.

Final land use designations were calculated as the "least wild" of any preceding land use designations. For example, if a piece of land was designated as Wildland Forest in 1988, Mixed Agriculture in 1996 and Rural Forest in 2004, then the 2004 land use designation was changed to Mixed Agriculture since Mixed Agriculture was defined as "less wild" than Rural Forest. The land use designation trajectories are shown below:

More wild Wildland Forest | Rural Forest | Other Forest | Intensive Agriculture | Mixed Agriculture | Other Agriculture | High-Density Residential | Low-Density Residential | Urban | Water Less wild Unknown

Land Use Change

Land use change was calculated by combining (see ArcInfo "combine") the three time steps into a single raster dataset. This raster dataset has land use attributes for each of the three time steps and a unique VALUE for each land use change vector (i.e. Wildland Forest &gt; Rural Forest &gt; Low-Density Residential is VALUE 229). The land use change development attribute was created to quickly symbolize the areas of least and greatest change in development by analyzing the transition from one land use classification to another:

1. No Development Increase: land uses for all three time periods are the same. 2. Minor Development Increase: land use groups for all three time periods are the same. 3. Some Development Increase: land use group has changed from Forest to Agriculture or from Agriculture to Built. 4. Major Development Increase: land use group has changed from Forest to Built 5. Unknown: land use is unknown, cloud/shadow or water in at least one time period and has changed to/from another land use.
