Dataset Abstract:

This data set contains GIS coverages constructed from measurements taken of logged areas in Juruena, Mato Grosso. Classes include roads, skids trails, tree crowns, tree-fall locations, and block boundary (Asner et al., 2004). Coverages are in ArcInfo SHAPE format (*.shp), UTM projection, using the WGS84 datum.

Data Characteristics (Entity and Attribute Overview):

Data Characteristics:

[The data files for each parameter (e.g., skids, roads) are in the SHAPE file format and are combined in compressed files for

each parameter and time frame as appropriate. These data are in the SHAPE file format in the UTM projection, using the WGS84 datum, Zone 21S.



Files include:



Juruena_Blocks_Polygons_UTM.zip This layer shows the logging blocks as polygons.



Juruena_Blocks_Roads_GIS_UTM.zip This layer shows the logging roads in the various blocks.



Juruena_Blocks_Skids_GIS_UTM.zip This layer shows the logging skids in the various blocks.



Juruena_TreeCrowns_GIS_UTM_2002NOV12.zip and Juruena_TreeCrowns_GIS_UTM_2002NOV15.zip



These two layers show the GPS locations of tree crowns (copa) after cutting, on 15-Nov-2002 and 15-Nov-2002, respectively.





Juruena_SkidTrails_GIS_UTM_2002_Nov.zip This layer shows skid trails during field work in November of 2002.



Juruena_TreeFalls_GIS_UTM_2002_Nov.zip This layer shows GPS locations of tree falls (stump location) during field work in November of 2002.



* Skid or Skid Trail means a temporary pathway principally used to drag or transport felled trees or logs or other material to a landing.



* Road or Access Road means a temporary or permanent access route.

Data Application and Derivation:

These data can be used to identify how logging activity affects reflectance measurements from multi- and hyper-spectral imagery.

Quality Assessment (Data Quality Attribute Accuracy Report):

Quality Assessment:

These data were compared with imagery of the area to visually confirm the location of roads and other features visible in the imagery.

Process Description:

Data Acquisition Materials and Methods:

A Leica GPS unit was used to collect the location of the features in the field.
