  • tran.py:Convert grid indexes to latitude, longitude and time information.

Document catalog description

  • parameters:
    • boundary.txt:Latitude and longitude range of the trajectory.
    • cellSize.txt:Divide the size of the grid.
    • neighborFile.txt:Record neighboring grids for each grid.
    • time.txt:Time horizon of the trajectory.
    • timeStep.txt：The duration of the interval(minutes).

How to run

Python

The version of python used in this code is python == 3.8.

Prepare data

Firstly, put Original.txt in the data/raw_data/. The data format is shown below:

Diagrams

In this code, we provided 5000 trajectorys in data/raw_data/Original.txt

Run the code

Firstly, modify parameters data/parameters/ in the following format.
Separate by spaces.

  • boundary.txt: lon_left lon_right lat_bottom lat_top
  • cellSize.txt: cellH cellW
  • time.txt: startTime endTime
  • timeStep.txt: The duration of the interval(minutes)

Secondly, modify parameters in code.

  • In TPM.py
    • In main: eps，name, times

Thirdly, run TPM.py.
