Error when trying to execute GPS track / GPS points in CSV file

[rsantosb]

I have tried to run the following code (available in example/command_line_example):

GPS trajectory matching in CSV file using fmm:

XML configuration

fmm fmm_config_csv_trajectory.xml
# Command line arguments
fmm --ubodt ../data/ubodt.txt --network ../data/edges.shp --gps ../data/trips.csv --k 4 -r 0.4 -e 0.5 --output mr.txt

GPS point matching in CSV file using fmm:

XML configuration

fmm fmm_config_csv_point.xml
# Command line arguments
fmm --ubodt ../data/ubodt.txt --network ../data/edges.shp --gps ../data/gps.csv --gps_point -k 4 -r 0.4 -e 0.5 --output mr.txt

Also the notebook: stmatch_example.ipynb specifically the part "Match GPS data stored in a file". (I copied in a file fmm_test_new.py the stmatch_example.ipynb).

I always get the following error:

[2022-11-24 10:55:11.856] [critical] [gps_reader.cpp:137] Id id or Geometry column geom not found Traceback (most recent call last): File "fmm_test_nuevo.py", line 34, in status = model.match_gps_file(input_config, result_config, fmm_config) File "/usr/lib/python2.7/dist-packages/fmm.py", line 1217, in match_gps_file return _fmm.FastMapMatch_match_gps_file(self, gps_config, result_config, config, use_omp) RuntimeError: Id id or Geometry column geom not found

I followed all the installation steps correctly, without any error.

The GPS data format is not corrected identified by the program.

Compare your data with the two files to check the form including field name

• https://github.com/cyang-kth/fmm/blob/master/example/data/gps.csv
• https://github.com/cyang-kth/fmm/blob/master/example/data/trips.csv

I am trying to run the example files and it fails every time. What can I do?

Thank you!
