Alternative stream network data for the SAFE Project (Q11202)

Description: This zipfile contains three shapefiles of linear geometries showing channel networks across the SAFE landscape.RIVERS_UTM.shp: From Igor Lysenko's SAFE pack, this is a river network with two areas, covering Maliau and the area around the SAFE experimental region. The network density is much higher in Maliau than SAFE and the channel network around SAFE is not complete. This is projected in UTM50N WGS84.LFEriver_SL.shp: This is provided (by Sarah Luke?) through Clare Wilkinson's GIS files and adds a critical missing stream for the Logged Forest Edge (LFE) catchment. This is projected in UTM50N WGS84.all_rivers.shp: This is provided through Clare Wilkinson's GIS files and provides streams for a single region covering Danum and the SAFE experimental region but not sampled watersheds in Oil Palm plantations to the south of SAFE. The original file is missing projection information (no .prj file) but other files in the same dataset are projected in RSO Timbalai 1948 and using this projection fits with the context of other data. The version uploaded onto Zenodo has been reprojected into UTM50N WGS84.Although the files are not consistent, they do contain channels and channel data that are referenced in some studies. The provenance of these files are unknown, although the following suggests that they may be traced using GPS or from imagery:Incomplete coverage within the regions they cover.Treatment of larger rivers, changing from a single line feature showing the stream centreline (?) to double lines showing the river banks.Variation in network density: the western edge of all_rivers.shp shows a vertical band about 4 km wide of higher stream density than the rest of the region; RIVERS_UTM.shp shows marked differences in stream density between SAFE and Maliau.Project: This dataset was collected as part of the following SAFE research project: SAFE CORE DATAXML metadata: GEMINI compliant metadata for this dataset is available hereFiles: This dataset consists of 2 files: SAFE_Alternative_Stream_network_metadata.xlsx, Preexisting_SAFE_river_files.zipSAFE_Alternative_Stream_network_metadata.xlsxThis file only contains metadata for the files belowPreexisting_SAFE_river_files.zipDescription: Contains three shapefiles of channel networks.This file contains 3 data tables:Feature properties (described in worksheet LFEriver_SL)Description: Field descriptions for shapefile propertiesNumber of fields: 1Number of data rows: Unavailable (table metadata description only).Fields: Id: Identity of river (Field type: id)Feature properties (described in worksheet RIVERS_UTM)Description: Field descriptions for shapefile propertiesNumber of fields: 1Number of data rows: Unavailable (table metadata description only).Fields: NAME: Local name of segment (Field type: comments)Feature properties (described in worksheet all_river_UTM50N_WGS84)Description: Field descriptions for shapefile propertiesNumber of fields: 10Number of data rows: Unavailable (table metadata description only).Fields: FNODE_: Unknown (Field type: numeric)TNODE_: Unknown (Field type: numeric)LPOLY_: Unknown (Field type: numeric)RPOLY_: Unknown (Field type: numeric)LENGTH_MET: Length of channel segment in metres (Field type: numeric)RIV_YSC_: Unknown (Field type: numeric)RIV_YSC_ID: Unknown (Field type: numeric)CODE: Unknown (Field type: numeric)NAME: Local name of segment (Field type: comments)AREA: Local area of segment (Field type: comments)Date range: 2010-10-01 to 2019-10-01Latitudinal extent: 4.0223 to 5.9761Longitudinal extent: 116.0242 to 117.9758
