Seattle Tree Centroids 2021

This dataset represents tree centroids derived from LiDAR data. The tree centroids are the estimated location of the central point of each tree. The tree centroids were derived using LiDAR data. The operation was constrained to those areas of tree canopy, using the tree canopy dataset developed separately for this project, which employed automated techniques coupled with manual editing to extract tree canopy from imagery and LiDAR. Mapping of tree centroids was performed using an automated feature extraction technique that incorporated segmentation and morphology routines. The automated routine first created objects from the tree canopy using an inverse watershed segmentation algorithm applied to the LiDAR nDSM (normalized digital surface model) datasets. These objects were then refined using the spatial properties of the objects. Centroids were computed by finding the geometric center of the tree object. Attributes include the tree height and radius. The height was calculated using the 98th quantile of the LiDAR nDSM height to reduce outlier values. The radius was then calculated from the tree centroid using the formula.<div><br /></div><div><span style='font-family:&quot;Avenir Next W01&quot;, &quot;Avenir Next W00&quot;, &quot;Avenir Next&quot;, Avenir, &quot;Helvetica Neue&quot;, sans-serif; font-size:16px;'>For more information, please see the </span><a href='https://seattle.gov/documents/Departments/OSE/Urban%20Forestry/2021%20Tree%20Canopy%20Assessment%20Report_FINAL_230227.pdf' style='color:rgb(0, 97, 155); text-decoration-line:none; font-family:&quot;Avenir Next W01&quot;, &quot;Avenir Next W00&quot;, &quot;Avenir Next&quot;, Avenir, &quot;Helvetica Neue&quot;, sans-serif; font-size:16px;' target='_blank' rel='nofollow ugc noopener noreferrer'>2021 Tree Canopy Assessment</a><span style='font-family:&quot;Avenir Next W01&quot;, &quot;Avenir Next W00&quot;, &quot;Avenir Next&quot;, Avenir, &quot;Helvetica Neue&quot;, sans-serif; font-size:16px;'>.</span><br /></div>

TAP21 bg Seattle - Absolute % Change

<p>This data layer references data from a high-resolution tree canopy change-detection layer for Seattle, Washington. Tree canopy change was mapped by using remotely sensed data from two time periods (2016 and 2021). Tree canopy was assigned to three classes: 1) no change, 2) gain, and 3) loss. No change represents tree canopy that remained the same from one time period to the next. Gain represents tree canopy that increased or was newly added, from one time period to the next. Loss represents the tree canopy that was removed from one time period to the next. Mapping was carried out using an approach that integrated automated feature extraction with manual edits. Care was taken to ensure that changes to the tree canopy were due to actual change in the land cover as opposed to differences in the remotely sensed data stemming from lighting conditions or image parallax. Direct comparison was possible because land-cover maps from both time periods were created using object-based image analysis (OBIA) and included similar source datasets (LiDAR-derived surface models, multispectral imagery, and thematic GIS inputs). OBIA systems work by grouping pixels into meaningful objects based on their spectral and spatial properties, while taking into account boundaries imposed by existing vector datasets. Within the OBIA environment a rule-based expert system was designed to effectively mimic the process of manual image analysis by incorporating the elements of image interpretation (color/tone, texture, pattern, location, size, and shape) into the classification process. A series of morphological procedures were employed to ensure that the end product is both accurate and cartographically pleasing. No accuracy assessment was conducted, but the dataset was subjected to manual review and correction.</p><p>University of Vermont Spatial Analysis Laboratory in collaboration with City of Seattle.<br /></p><p>This dataset consists of City of Seattle Block Groups areas which cover the following tree canopy categories: </p><p></p><ul><li>Existing tree canopy percent </li><li>Possible tree canopy - vegetation percent </li><li>Relative percent change </li><li>Absolute percent change</li></ul><div style='font-family:inherit;'><div style='font-family:inherit;'>For more information, please see the <a href='https://seattle.gov/documents/Departments/OSE/Urban%20Forestry/2021%20Tree%20Canopy%20Assessment%20Report_FINAL_230227.pdf' style='color:rgb(0, 97, 155); text-decoration-line:none; font-family:inherit;' target='_blank' rel='nofollow ugc noopener noreferrer'>2021 Tree Canopy Assessment</a>.</div></div><div style='font-family:inherit;'><br /></div>

to what NAVD88 shows as &quot;mean high water&quot; (see official definition
below) at 7.97 feet. MEAN HIGH WATER (MHW): &quot;A tidal datum. The average of
all the high water heights observed over the National Tidal Datum Epoch. For
stations with shorter series, simultaneous observational comparisons are made
with a control tide station in order to derive the equivalent datum of the
National Tidal Datum Epoch.&quot; </span><a href='https://tidesandcurrents.noaa.gov/datum_options.html' target='_blank' rel='nofollow ugc noopener noreferrer'>Source</a><span style='font-family:Verdana, sans-serif;'>  &quot;The MHW line along the tidal shoreline is represented by the contour line
that is 8.0' above the NAVD 88. The MHW elevation is not necessarily an
equipotential (level) surface, but the variation from a level surface is not
significant for this project. The determination of MHW is based on 18 yrs of
tidal data and represents the latest official National Tidal Epoch of
1960-1978. The Seattle Tide Station (Sta No 944-7130) is located at the
downtown ferry terminal.&quot; Source: From paper by Nick Bodnar 10/18/1993
Some other definitions regarding these shorelines (from Nick Bodnar,
10/18/1993): LAKES UNION AND WASHINGTON SHORELINE (18.6' above NAVD 88) The
approximation of &quot;ordinary high water&quot;; the level of Lk Washington
varies from 17.0'-18.6' during the year; the max lake elevation is 18.8' as
controlled by Corps of Engineers (COE) at Hiram Chittenden Locks. The NAVD 88
lake elevations have been converted from the U.S. Engineers Datum. This zero of
NAVD 88 is 3.25' above the Locks Datum at the common bench mark P-7. The
shoreline contour of 18.8' above NAVD 88 should be used from the Locks,
upstream through Lk Union and Lk Washington. The COE has performed various
studies that show the level of Lk Wash to approximate an equipotential surface
that can be represented by a single contour elevation for mapping purposes.
OTHER LAKES The shoreline around Green Lake and all other lakes are delimited
by the water/land interface as seen on the aerial photography.</span></font></span></p>
