+## Migrate google location history takeout to traccar
+
+[download your google maps location history takeout](https://takeout.google.com/takeout/custom/local_actions,location_history,maps,mymaps?)
+
+select location history only
+and json as format
+extract the Records.json
+
+you'll use a python script to limit the resaults to just time , latitude and longitude converted to proper coordinates
+
+`git clone https://github.com/Scarygami/location-history-json-converter`
+
+`cd location-history-json-converter`
+
+`pip install -r requirements.txt`
+
+`python location_history_json_converter.py Records.json  output.csv -f csv`
+
+csv output will generate Comma-separated text file with a timestamp field and a location field
+we'll add a deviceid , protocol and valid fileds to it
+
+`sed 's/^/osmand,1,/; s/$/,1/' export.csv > curated.csv`
+
+delete the "1" from the first line an replace osmand with protocol in the first line
+
+so now the file looks like
+
+```
+protocol,Time,Latitude,Longitude
+osmand,1,2012-08-25 21:26:20,37.95954620,23.72793730,1
+```
+
+5 columns
+osmand
+1
+time
+lat
+lon
+
+We are going to parse those values to as sql `LOAD DATA LOCAL INFILE` statement to the appropriate tc_position table fields
+
+copy the csv to the container
+
+`docker cp curated.csv traccar-db:/`
+
+open a root mysql shel to the db container
+
+`docker exec -it traccar-db mysql -uroot -pROOTPASSWORD`
+
+connect to database
+
+`use traccar-db`
+
+load the data 
+
+```
+LOAD DATA LOCAL INFILE 'inn.csv' INTO TABLE tc_positions FIELDS TERMINATED BY ',' (@osmand,@deviceid,@Time,@Latitude,@Longitude,@valid) set protocol=@osmand,deviceid=@deviceid,devicetime=@Time,fixtime=@Time,servertime=@Time,latitude=@Latitude,longitude=@Longitude,valid=@valid;
