List sorting capabilities

« on: June 22, 2006, 05:55:21 AM »

1) Within the waypoint listing area, it would be great to be able to have a column for "distance" which would of course be based on the current location.
1a) Maybe provide a feature for the user to actually choose which columns they want in this area

2) In this same "waypoint listing area", it would be great to be able to sort the list by either name or by distance (of course showing the actual distance from current location)

3) Also in this same area, it would be great to have the capability to set a filter (like perhaps within a specific distance or only show caches NOT found) to trim down the list.

Just my .02 cents worth...

Good idea.

We are looking at the list functionality for distance and for some other reasons.

It may be necessary to keep a smaller set (say 20 nearest waypoints) when sorting by distance, in order to keep them updated without bogging things down. About like what you said for filtering.

How's the list sorting coming......another idea...especially for Places. If there were a way to filter out the items in the list you don't want to see......That would be great. Thanks for all your hard work Nathan.

Some List Sorting is available in 2.2.2. There was actually quite a bit of tricky math involved in doing these. I won't bore you with the details of forming a query based on an approximate distance, then recomputing based on the results of the query, then sorting according to distance.

There are two new options on the List Page:

Nearest Places:Nearest places to the GPS Location (or center of map screen), sorted by distance
Nearest Waypoints:Nearest waypoints to the GPS Location (or center of map screen)

Note that periodically (about every 20 seconds), it will update the distances in response to position updates.

First things first.....Nathan, you rock! Now, have you given any thought to the filtering of different items in the lists? Because my wife has a thing for old cemetaries.....but when I get the Places on the screen....sometimes it gets a little crowded....Thanks, Steve

I've looked at it enough to know it is possible, but don't have all the details worked out.

In many ways, a context menu might be good for this situation, but they can be hard to use in a dry bag or otterbox.
