Hard copies are available for purchase at some Forest Service offices, U.S.Geotiffs that contain both collar and non-collar editions in a single zipped file.These maps are available in several formats: FSTopo maps are 7.5 minute, 1:24,000-scale over the conterminous United States, and 15 minute X 20-22.5 minute, 1:63,360-scale over Alaska.

Each map covers all or part of one wilderness area and the scale is generally 1 inch per mile (1:63,360).įSTopo is the Forest Service series of large scale topographic maps. Wilderness Maps are topographic maps that show natural features such as mountains, valleys, plains, lakes, rivers, and vegetation using contour lines depicting elevation gain or loss.

“ A Guide To Your National Forests” is a free brochure showing locations of national forests and grasslands along with contact information.įorest Visitor Maps, National Forest Atlas, and Wilderness Maps We've released the next generation Interactive Visitor Map! Visitor Map 2.0, provides the public with an online view of Forest Service roads, trails, recreation sites, wilderness areas, and wild & scenic rivers. OID are identifiers of the rows (starting at 0, increasing by 1), VALUE are the different integer values stored in the raster, COUNT is the number of pixels for each value.The Forest Service publishes a variety of map products to help you plan your next adventure or enjoy your next visit! National Overview Maps OID, VALUE and COUNT are required columns (integer type), then you can add additionnal columns (e.g.

The file must have the same name as the raster (with a *. extension). So you could automatically make the attribute table in R. I haven't tested, but R can create dbf files.

Then you can either manually edit the table to add your text label (writing each category one by one), or add the information using a joint table (if you have a large number of classes, this will be faster). It can be done in ArcGIS with the command "build raster attribute table". This table, which stores categorical information and optionnally the text labels, is a specific dbf table. In ArcGIS, the raster will be considered as a categorical raster if it is associated with a "raster attribute table". In orde to optimize the size, Byte should be used if less than 255 categories. WriteRaster(df_rstr, "~/dummy.tif", overwrite = T)ĭimensions : 4, 5, 20 (nrow, ncol, ncell)Įxtent : 0.5, 5.5, 0.5, 4.5 (xmin, xmax, ymin, ymax)Ĭrs : +proj=utm +zone=11 +datum=WGS84 +units=m +no_defsĪ tif raster with categorical values will always store the information as Integer, then a look up table is used by different softwares to translate the information from the numerical value to its labels.

Maybe I have to use the raster::ratify function, but I am not sure at what step was I suppose to use it. The raster attributes show as intended in R, but after saving the raster and loading it in ArcGIS the character attributes don't show up, as the open attribute table option is greyed out. I created a landcover classification raster using a dataframe in R.
