Syphard Teresa J. Brennan-Kane Heather Rustigian-Romsos Jon E. Keeley 20220409 Publication Ecological Applications online early n/a Wiley https://doi.org/10.1002/eap.2626 This dataset contains data pertaining to ground surface cover in 30 meter plots around a random selection of points within chaparral from Santa Barbara county south to San Diego County in southern California, USA. These data were obtained from historical aerial imagery from 1943 to 1959 and current imagery from 2016 to 2018 and they were compared to quantify changes in cover type over time. The data were collected in order to assess the extent of chaparral type conversion and its drivers in southern California. 19430101 20181231 ground condition Complete None planned Southern California chaparral type coversion study area -120.6797 -116.2210 35.6825 31.9300 ISO 19115 Topic Category imageryBaseMapsEarthCover biota environment USGS Thesaurus shrubland ecosystems image analysis None chaparral type conversion USGS Metadata Identifier USGS:6297d7fad34ec53d276c5b37 None Southern California None.

No accuracy assessments were conducted. The data match up with the details we have provided about them and they fall within the expected range of Southern California. There are no duplicates or omissions. No topology tests were conducted. The data only represent a change in ground cover type for a random selection of points within in southern California chaparral between the years 1943-1959 and 2018.

A random set of spatial points were generated in ArcGIS within areas of chaparral vegetation in southern California, USA . Aerial imagery corresponding to each point was then collected for a historical point in time between 1943 and 1959 and a present day point in time between 2016 and 2018. Historical imagery was downloaded from the University of California Santa Barbara Map and Image Library as tiff files that were then georeferenced using at least 10 points matching points and the spline transformation. The imagery for 2016-2018 was the National Agriculture Imagery Program (NAIP) imagery, which can be accessed from the ArcGIS online library. The land cover data in this dataset was then generated by visually estimating various ground surface cover types within a 30 meter radius around each random point from both the historical and present day images. The land cover classes used included : Woody vegetation Rock Bare ground and grass Urban development (paved roads and structures considered to be permanent on the landscape) The data were estimated into categories as follows: 0 - 0 percent 1 - 1-5 percent 2 - 6-25 percent 3 - 26-50 percent 4 - 51-75 percent 5 - 76-94 percent 6 - 95-100 percent Human disturbance was also quantified using the categories above and the type of disturbance was identified and included things such as pavement, structures, fuelbreaks, dirt roads, trails, reservoirs, agriculture, etc. Historical aerial imagery NAIP imagery 20210120 Vector Entity point 4067 Albers Conical Equal Area 29.5 45.5 -96.0 23.0 0.0 0.0 coordinate pair 0.6096 0.6096 meters North_American_Datum_1983 GRS_1980 6378137.0 298.257222101 TypeConvSouthernCA.shp Attribute Table Table containing attribute information associated with the data set.
