Sažetak
This study intended to develop a road network planning for timber harvesting in tropical
forests in Peru using georeferenced and field data and Geographic Information System (GIS).
The Digital Elevation Model (DEM) Alos Palsar 12.5 m was used. The DEM was processed
to generate the hydrography and terrain slope maps. A weighted raster was created using
overlapping weights of the slope raster and the hydrography map. We created a least cost path
raster by using the weighted raster origin and destination points. We used a Triangular Irregular
Network (TIN) to validate the Least Cost Path. In addition, histograms of the trajectory
of each path with altitude and slope values were generated. We observed that the forest
road planning using GIS provided better definition (economically and environmentally) of
road networks in our forest site than those traditionally defined using conventional mapping
techniques.
