Visibility Analysis (VGA) on Dota 2 Maps

Blogpost

Technical Pipeline:

data acquisition (R)

1. Download/Borrow Raster Files from https://github.com/devilesk/dota-interactive-map
2. Crop Raster Files and Combine Layers (Trees and Boundary)
3. Convert Rasters into Polygons/Polylines

data processing (DepthmapX)

4. Import Data into DepthmapX
5. Run VGA - Visual Graph Analysis

data preprocessing and visualization (R)

6. Import VGA as SpatialPixelsDataFrame
7. Plot SpatialPixelsDataFrame
8. Build Time-Series Plot Animations
9. Resize SpatialPixelsDataFrame to fit map image (260x260) -> (4096x4096)

analysis (QGIS)

10. Visualize in QGIS alongside full Map Images

*You probably could do this manually, but because of the large number of map files- I did it as a batch process mostly in R.
