POI import anomalies

[David Steiner]

I am trying to import POI groups into the Route Planner. In this particular case a list of all the covered bridges in my state (New Hampshire). This is a subset of a CSV of all covered bridges in the US. To do this, I used the following methodology:

• found the lat/long for the corners of a bounding box that covered the state. This covers a bit of surrounding states but I figured that I could edit outliers after seeing them plotted.
• sorted the master file by lat and long, and removed any entries outside the bounding box
• imported the resulting file to the Route Planner.

This seemed to work as expected but upon closer inspection, I found a couple of strange things:

• there are 5 POIs shown that are outside the bounding box that I can not find if I search in the CSV. None of these are actually bridges (four of them are waterfalls).
• When I look in the CSV, I see at least one bridge that is outside NH (I recognize the name) but I think is inside the bounding box however it does not show as a POI in the Route Planner.

Can anyone give me a clue as to why this may be happening?
Thanks.
