i have GPS data from 15 trucks for one month. The data include (location x-y, speed, altitude and vehicle_id). I have used tracking analyst to visualize the data but i need to group them by day to show each truck's trip in detail. Because not all the cars travel every day and same hours.. So i get no result if i put them altogether.
How can i check that my GPS data has no bias?
i observed that there are cases when a truck makes a trip from a to b it turns off the gps at b and the other day it starts again from a. So when i get ArcGIS to calculate distances it appears a wrong (and often too big) distance.
How can i fix that? Should i split my dataset by day?
