However, if you just want a vehicle to draw a line while it travels, you can keep that functionality in the client. First, if you want to store vehicles' positions indefinitely, you'll need to collect them server-side and push them into your database.

And the line should automatically update in the map.Īs an afterthought, each GPS pulse should be dispatching an event that you may need/want to handle in two places. PointIndex = flightPlanCoordinates.length įlightPlanCoordinates=new (newLat, newLon) Insert a new point at the end of the LatLng Array. Insert a new GPS point into your Polyline's point array. Knowing that, I'd try it like this: // I assume you've got your GPS signal pumping updates to your client. Note that if you pass a simple array, it will be converted toĪn MVCArray Inserting or removing LatLngs in the MVCArray willĪutomatically update the polyline on the map. Specified using either a simple array of LatLngs, or an MVCArray of The ordered sequence of coordinates of the Polyline. Hope this time my title and description part is understood.įrom the Maps Javascript API docs for Polyline (note the path property): I am getting this result which is correct but want animation in it as in $newnode->setAttribute("lon", $row) īut now i wanted to show polyline with animation as show in 1st references site.Can any one suggest me some references or help me out in same. At the moment I'm struggling with allowing a user to delete a node. The result of this removal should be a new polyline connecting the two new neighboring nodes. Iterate through the rows, adding XML nodes for each I need to allow users to create polylines on a google map and also allow them to delete a node between the polylines they created. $query = "SELECT `lat`, `lon` FROM current_location Where Device_ID='HGS1005'" Select all the rows in the markers table $db_selected = mysql_select_db($dbname, $connection) ĭie ('Can\'t use db : '. I can delete extra lines, edit the nodes to extend or shrink lines. Var map = new (document.getElementById("map"), As such, there are multiple polylines of the same trails, some on different levels. I have also taken data for this from my SQL which is as follow:
#Gpsmapedit removing nodes from polylines code#
For that i refered the code from Google API tutorial Polyline. My experience is that GPSmapEdit is correct, so turn off the stop on error option of cgpsmapper and just do your error checking in GPSmapEdit.I wanted to show the polyline on google Map as car moves with animation (like in this site: ) by taking data from MySQL and PHP. If you run cgpsmapper with error reporting, it will report a lot of "Node too Close" errors that GPSmapEdit doesn't show.
It can also make malformed polygons really ugly, so I don't slice those.
Slicing non-routable objects greatly reduces compile time.
#Gpsmapedit removing nodes from polylines verification#
The second verification may show some errors with unspecified line types, which GPSmapEdit interprets to be roads. I'll then "ADD" or paste the routable elements onto this map, and verify the combined map. I'll combine all my topo, hydro, and wooded areas, generalize and slice them, and save the map. To keep things simple, I usually keep my routable data on a separate map from non-routable, and only verify the routable map after I've generated a routing graph. If any of GPSFileDepots master map makers familiar with this process would be so kind as to offer advice, i would be very grateful!ĭepending on your Verify Map options the Verify Map procedure will check lots of non-routing issues like malformed polygons. I assume I must run the 'Routing Graph Generator' after any map edits for the map to be exported with complete and accurate routing information. Why do all these errors reappear after running the 'Routing Graph Generator' again? I have not changed any data in the map between. However, If I re-run the 'Tools > Generate Routing Graph' function, and then re-run the map verification, I will again be presented with hundreds of errors, many of which appear to be duplicates from the previous verification.Īfter about the third time around, I did not save the new *.mp mapset, and undid ('ctrl-Z') the new routing graph. I can then save the map (*.mp) as is, and run the map verification at will, returning zero errors each time. I will get a list of several hundred errors, and I will spend hours correcting each error until the 'Verify Map' process no longer returns a single error. I will save my map in current configuration (*.mp) and select 'Tools > Verify Map.'. Recently, I have started to play with adding routing information to my maps using GPSMapEdit:
