Summary:

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.

LBA Data Set Inventory ID:  LC13_GIS_Juruena

These data are GIS data layers in SHAPE format of logging areas in Juruena , Mato Grosso . There is a separate SHAPE file for roads, skids trails, tree crowns, tree-fall locations, and block boundary. The Juruena data are in UTM using the WGS84 datum.

Related Data Sets:

• LBA-ECO TG-07 Fallen Necromass in Tapajos,Fazenda Cauaxi, Juruena Forests in Brazil(Coarse woody debris data collected by another team in the same area).

2. 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  

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.

Site boundaries: (All latitude and longitude given in degrees and fractions)

Time period:

• The data set covers the period 2002/11/12-2002/11/15.
• Temporal Resolution: 2002/11/12-2002/11/15.

Platform/Sensor/Parameters measured include:

• FIELD INVESTIGATION / GPS (GLOBAL POSITIONING SYSTEM) / LANDSCAPE PATTERN

3. Data Application and Derivation:

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

4. 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.

5. Data Acquisition Materials and Methods:

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

6. Data Access:

This data is available through the Oak Ridge National Laboratory (ORNL) Distributed Active Archive Center (DAAC) or the EOS Data Gateway.
