1. Extract the files from the zip file and copy them to your PC.
2. Run the file .../bin/OpenJump.exe.

Import the CSV Files into OpenJump HoRAE

1. Choose File > Open Files.
2. Select the CSV files (Ctrl + click each file) and click Next > Finish. The tracks are imported as layers.
3. Save the Project with a name (.jmp).
4. Select all layers, right-click Combine Selected Layers.
5. Save each new layer! Right-click and select Save Dataset As. Save layers in the same folder as the project.
6. To make the heatmap, select the Combined layer and from the MOVEAN menu choose HRE > Point KDE > Point Kernel Density.
7. The most important setting is the Distance h (smoothing factor), which is similar to the Smoothing value in EthoVision XT. You can have the software calculate it for you or you can enter a value in the same units as the coordinates. The value Cell Size is the size of each pixel in the heatmap: the greater the value, the grainier the image.
8. To change colors, select the layer Combined-KDE and from the Raster menu choose Raster Color Editor.
9. To hide the original data points, de-select all the layers except Combined-KDE.

Extras

To Create Probability Contours

1. Select the layer Combined-KDE and from the MOVEAN menu choose HR Analysis > Create Probability Contours from Raster.
2. Enter the probability value (e.g. 50%) and click OK.
3. De-select the other layers to view the contours.
