GPX files for iOS Simulator [closed]

由 末鹿安然 提交于 2019-11-28 17:11:46
Where I can find GPX file of any region that I can import to my iOS Simulator? iOS simulator does contain only static locations around the world (from XCode) or walk/bike/car drive in simulator itself. This is not good enough for unit testing or other specyfic cases. Schema for GPX file: http://www.topografix.com/GPX/1/1/gpx.xsd Is there a database or hidden option in Google maps to get location? You create a route and generate a gpx file here - http://www.bikehike.co.uk/mapview.php On another note it might help, are you aware the simulator can simulate movement if you run the simulator then

XmlSerialization and xsi:SchemaLocation (xsd.exe)

由 佐手、 提交于 2019-11-28 09:13:05
I used xsd.exe to generate a C# class for reading/writing GPX files. How do I get the resultant XML file to include the xsi:schemaLocation attribute eg. I want the following but xsi:schemaLocation is always missing <?xml version="1.0"?> <gpx xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" version="1.1" xmlns="http://www.topografix.com/GPX/1/1" creator="ExpertGPS 1.1 - http://www.topografix.com" xsi:schemaLocation="http://www.topografix.com/GPX/1/1 http://www.topografix.com/GPX/1/1/gpx.xsd"> </gpx> dtb Add this to your generated C# class:

GPX parsing patterns and “standards”

问题 I would like to continue the discussion from this post: GPX Schema validation problems. To go directly to the point, I want to ask how people are parsing and working with GPX files in their software or give me suggestions as to how one should do it. Although one may say, well just parse the trkpt elements and use them in your software, the things are not that simple for me. Firstly, as discussed in the cited post above, a lot of the gpx-producing-devices(software, gps-handheld-devices, etc)

Simplification / optimization of GPS track

由 强颜欢笑 提交于 2019-11-27 11:01:09
问题 I've got a GPS track produced by gpxlogger(1) (supplied as a client for gpsd). GPS receiver updates its coordinates every 1 second, gpxlogger's logic is very simple, it writes down location ( lat , lon , ele ) and a timestamp ( time ) received from GPS every n seconds ( n = 3 in my case). After writing down a several hours worth of track, gpxlogger saves several megabyte long GPX file that includes several thousands of points. Afterwards, I try to plot this track on a map and use it with

Use Google maps API to draw a polyline that changes color

问题 I'm working on a project that plots a track from GPX file onto google maps, and color-code it with an attribute (let's call it Score ). I've done some editing that now there is an additional tag Score for each coordinate in this GPX file. Here is a snippet of my modified GPX file. <trkpt lat="50.834048" lon="-0.127354"> <ele>31.0</ele> <Score>-0.64730385</Score> <time>2016-07-07T14:31:51Z</time> </trkpt> <trkpt lat="50.833833" lon="-0.127600"> <ele>31.0</ele> <Score>-0.647203</Score> <time

When using GPX in Xcode to simulate location changes, is there a way to control the speed?

由 ぃ、小莉子 提交于 2019-11-27 06:41:57
I'm using the following GPX file in Xcode 4.2 to simulate a location change. It works well, but I can't control the speed of the location change. stamp seems to be not working. Does anyone have a solution for this? <?xml version="1.0"?> <gpx version="1.1" creator="Xcode"> <wpt lat="37.331705" lon="-122.030237"></wpt> <wpt lat="37.331705" lon="-122.030337"></wpt> <wpt lat="37.331705" lon="-122.030437"></wpt> <wpt lat="37.331705" lon="-122.030537"></wpt> </gpx> JiaYow I don't think (know) that this is possible in the GPX directly, but you can test location change with Instruments/Automation. You

How to calculate distance from a GPX file?

由 两盒软妹~` 提交于 2019-11-26 19:51:51
问题 I have a GPX file with a GPS track. Now I want to calculate the distance I covered with this track. What's the best way to calculate this? 回答1: The traditional way of calculating the distance between two points (each pair of waypoints in your GPX file) is with the Haversine formula. I have a SQL Server function that implements the algorithm. This should be easy to translate into other languages: create function dbo.udf_Haversine(@lat1 float, @long1 float, @lat2 float, @long2 float) returns
