This function allows you to calculate a distance matrix between one or two tables, for all combinations.
Input:
SHP / TAB files with point objects.
A unique ID field should be present.
Projection should be the same as the network.
You can swap the tables, since it is faster, if the from-table has less records than the to-table.
Options
"Build route objects" control if you are getting just the time and distance or also the actual route chosen.
This takes more time and generates much bigger files in large networks.
"Calculate both ways" is only relevant where the same table is used for both TO and FROM table.
When disabled, you only get the distance from A to B (not from B to A), giving you a matrix of half the size in shorter calculation time.
Use it when there are no one-way streets or turn restrictions.
Output:
Distances are stored with 3 decimals, while time (minutes) have 2 decimals.
A progress bar estimates when the process finishes.
