SAFE experimental site layout GIS files

Description: These zipfiles contain shapefiles showing the layout of the SAFE experimental area. The layout shapefile shows the realised locations of the experimental features within the wider converted landscape and the two fragment shapefiles show the planned circular fragments, as originally planned and as marked on the ground using GPS. These files were compiled from a wider set of GIS files and further details of the processing can be found here https://www.safeproject.net/dokuwiki/safe_gis/safe_layout. Project: This dataset was collected as part of the following SAFE research project: SAFE CORE DATA XML metadata: GEMINI compliant metadata for this dataset is available here Files: This dataset consists of 2 files: SAFE_GIS_Layout_metadata.xlsx, SAFE_layout_shapefiles.zip SAFE_GIS_Layout_metadata.xlsx This file only contains metadata for the files below SAFE_layout_shapefiles.zip Description: Contains three shapefiles. The layout shapefile shows the experimental fragments, riparian reserves and other features of the landscape and the two fragment files show the planned and then field walked edges of the main fractal fragment areas. This file contains 3 data tables: SAFE experimental site layout (described in worksheet SAFE_layout) Description: Properties for SAFE_Layout_UTM50N_WGS84 shapefile Number of fields: 4 Number of data rows: Unavailable (table metadata description only). Fields: CATEGORY: Category of feature (Field type: categorical) LANDCOVER: Landcover type of feature (Field type: categorical) WIDTH: Width of feature - does not apply to these features so these values are all NA.

Number of fields: 4 Number of data rows: Unavailable (table metadata description only). Fields: CATEGORY: Category of feature (Field type: categorical) LANDCOVER: Landcover type of feature (Field type: categorical) WIDTH: Width of feature - does not apply to these features so these values are all NA. (Field type: numeric) CODE: Names of fragments (Field type: location) Planned fragment polygons (described in worksheet SAFE_planned_fragments) Description: Properties for SAFE_planned_fragments_UTM50N_WGS84 shapefile, containing planned circular footprints of fragments. Number of fields: 4 Number of data rows: Unavailable (table metadata description only). Fields: CATEGORY: Category of feature (Field type: categorical) LANDCOVER: Landcover type of feature (Field type: categorical) WIDTH: Width of feature - does not apply to these features so these values are all NA.
