Output files

LSCorridors creates two types of output maps per source-target (ST) pair:

  1. a raster indicating all replicate corridors for the source-target pair;
  2. a folder with a vector version of the corridors for the source-target pair.

The end of the names of both files and folders indicate the variability and scale parameters used as input, the source-target patches simulated, and the simulation method (e.g Resistance_map1_var_5_0_scale_150_S_00012_T_00004_MP, wherein variability and scale parameters are 5.0 and 150, source and target patches are respectively “12” and “4”, and the simulation method is "MP").

Also, maps summarizing the resulting corridors for all combination of source-target patches for each simulation method are generated. A text (extension .txt) file with descriptive corridor information is generated with information about all simulations.

GIS files

In the main output folder, a raster file (extension .tif) is produced with all replicate corridors for each source-target pair, for each simulation method. Also, inside each created folder (corresponding to each ST pair) a set of four GIS files are exported for each corridor simulated (extensions .shp, .dbf, .prj and .shx), which allows the user to open each simulated corridor as vector in GIS softwares.

Besides the results for each source-target pair, a raster map is exported in the main output folder, summarizing the simulation of the all replicates of simulated corridors for all source-target pairs, for a given simulation method. This maps indicates the route selection frequency index (RSFI), i.e., it indicates the number of corridors that passed by each pixel of the map.

Descriptive data files

In the output folder a text file is created. This file contains descriptive data of each source-target patch combination, each variability and scale value, and each simulation method, whereas each row represents one corridor simulation. The columns represent, respectively:

  1. EXPERIMENT: the "experiment info", which may be the name of the resistance map or the prefix of the output files defined by the user;
  2. VARIABILITY: the variability parameter used as input for corridor simulations;
  3. SCALE: the biological scale of landscape influence used as input for corridor simulations;
  4. SIMULATION_METHOD: the code of simulation method (MP, MLmin, MLavg, or MLmax);
  5. SIMULATION_NUMBER: the number of the simulation;
  6. SOURCE: the corridor source patch ID;
  7. TARGET: the corridor target patch ID;
  8. CORRIDOR_LENGTH: the length of the simulated corridor, in meters;
  9. CORRIDOR_COST: the cost of the corridor (sum of the resistance values of each pixel crossed by the simulated corridor);
  10. EUCLIDEAN_DISTANCE: the Euclidian (straight line) distance between the centroids of the source and target patches.
  11. COORD_SOURCE_X: the longitude coordinate of the centroid of the source patch;
  12. COORD_SOURCE_Y: the latitude coordinate of the centroid of the source patch;
  13. COORD_TARGET_X: the longitude coordinate of the centroid of the target patch;
  14. COORD_TARGET_y: the latitude coordinate of the centroid of the target patch.

Analyzing outputs

Using the GIS and text files generated as output by LSCorridors, the users may perform analyses of corridor output outside LSCorridors package, using the platform of one's preference.
