osmsharp / ui

The UI components.

OsmSharp

This repository is not maintained anymore. Check osmsharp.com for more info.

From the website:

OsmSharp used to do everything on top of what it does today, including routing and rendering geo data. This was too much and the name OsmSharp didn’t make sense anymore. Now the old functionality has been replaced by several seperate projects:

• OsmSharp: Working with OSM-data, filtering, transforming.
• Itinero: The routing project is now maintained under the name Itinero.
• UI: This UI and rendering project has not been replaced. Instead we recommend using Mapsui.

ui's Issues

MapTapEvent not triggered on Android

Also check iOS.

MapView on iOS keeps refreshing

Too many events are reported. MapView keeps refreshing while there is no need.

MapMarker Align option

Add an option to center, bottom-center, top-center the map markers.

Evaluate PCL

Add overloads to Map.AddLayer

Make it easier to add layers to the Map object.

Ex:

Add Layer (Scene)
Add Layer (TileUrl)
Add Layer (Gpx)
Add Layer (Kml)

Re-implement turn restrictions

Implement a RouteTrackerAnimator

Implement a RouteTrackerAnimator: Animates the progress along a given route using the RouteTracker and the given GPS position. Moves the MapView to the correct Zoom, Tilt and Center.

OsmSharp Route => GeoJSON

• Implement a conversion to GeoJSON of an OsmSharp route.
• In one go look at serializing other geometries to GeoJSON.

-> Use external library (licence (!))

Flag to disable logging

Create a setting to disable logging on Android/iOS.

Some valid multipolygons don't show up

Some valid OSM multipolygon relations aren't rendered on the map.

Clip to bounds in iOS

Clip to bounds in iOS flag.

ZoomToMarkers for one marker

Zoom to markers does not work when there is only one marker.

MapCSS: Process eval functions

Add the eval functionality to the MapCSS parser/interpreter.

Some geometries with a 'width' property are rendered as a single line making airports and river/canals not show up on the map.

Add angle parameter to router tracker.

Add an angle parameter to the router tracker to use the compass for map orientations.

Rotate detection on Android does not reset.

Rotate detection on Android does not reset.

Routing flatfile

Implement a flat graph serialization.

Serialization already exists for a CH-graph and and a regular graph in blocks (for mobile use) but there are also important use-cases for one giant flat-file.

• Pre-process on another machine.
• Pre-process on another machine and load in service with no downtime.
• Create pre-processed files per country for download.

Implement a RouteTracker

Implement a RouteTracker: Tracks the current position along an existing route and determines when to recalculate. Contains the next instruction to follow.

Thread-safety of scene deserialization

Make sure the new scene object in the 'scenes' branch is also thread-safe. This is expected behaviour.

Double tab zoom on Android

Double tab zoom on Android

CalculateTSP failed on one and two-point routes

System.Net.WebException When Tile loading

I run the OsmSharp.WinForms.UI.Sample

use this layer
map.AddLayer(new LayerTile(@"http://b.tile.openstreetmap.org/{0}/{1}/{2}.png"));

Timeout exception occurs sometimes

Android & iOS

Label-placement

Implement a simple (greedy) label placement algorithm.

• Works on all plaforms (in Renderer2D class).
• Prioritize labels.

This will already be better compared to the current situation where there is nothing stopping the rendering code from rendering overlapping labels.

Weird iOS bug

Repeated crashes after long scrolling, zooming panning.

International text support

Hi. You need to change all occurrences of
ASCIIEncoding.ASCII
by
Encoding.UTF8
in the file PBFOsmStreamSource.cs

Example:

string key = ASCIIEncoding.ASCII.GetString(block.stringtable.s[(int)node.keys[tag_idx]]);

string key = Encoding.UTF8.GetString(block.stringtable.s[(int)node.keys[tag_idx]]);

Thanks.

iOS project?

Hi, I really want to try osmsharp so I installed Xamarin on a Mac. I never used it, I read some documentation and I can open other projects but I really cannot run the osmsharp iOS sample app.

Can you please explain the steps to run it? I cannot see the run option, it says that no executable are available and it doesn't let me select any simulator or device (the selection is grayed out).

Thank you!

MapView iOS does not refresh

MapView does not refresh on layout change.

MapMarker problems

Remove this.Location = in MapMarker constructor.
Remove or update the bitmap property, it always returns the static default image.

MinMax zoom settings on iOS

MinMax zoom settings on iOS

RISK: make sure the 'zoomToMarkers' does not exceed the max/min zoom bounds.

Zoom to current markers

Zoom to current markers

Legacy Code: Remove some of the old code from OsmSharp.Redis

There is some old code around in the OsmSharp.Redis to create custom hashes and tile calculations.

There is other code for this now.

Simplify MapMarker

Simplify the usage of the MapMarker by creating a marker object and the adding this to the MapView.

iOS: Add tapped event

Add an event to detect simple 'taps' on the map view in iOS.

accessible highway types are missing

The following accessible highway types are missing in constructor of "Osm.Routing.MotorVehicle.cs" class.

• primary_link
• trunk_link
• motorway_link

As a result, generated routes are often not the shortest/fastest.

Multipolygon Rendering

The multipolygon rendering is not accurate enough. Take into account the inner rings and split large polygons into small pieces.

Add option to serialize Route to GeoJSON

Implement a serialization to GeoJSON.

-> this can be used in the OsmSharpService

Change 'IsInside' to 'Contains'

Change 'IsInside' to 'Contains' on BoxF2D. It's unclear what this method does now.

From hex for simple color

Add a from hex function on SimpleColor

Default settings MapView

There are no default settings in the MapView:

Set default zoom, tilt and location.
Set map object in constructor.

Panning does not work in iOS 7

Problem with panning in iOS 7

Router tracker outside of map

Router tracker crashes when too far from route.

Finish polygon contains function

Add map marker for iOS

The iOS mapview has no markers yet.

MapView animation

Implement a MapView animator: Move to a new Center, Tilt and Zoom level in a smooth way in a given time period.

Have the possibility to disable movement and / or orientation

Right now it's not possible to disable the mapview from interacting with the user by dragging or rotating.

It should be possible to disable both functionalities.

Add bearing to MapView

Add a bearing property to the MapView and update the view accordingly.

This is to add the ability to turn the map in another direction than 'north-above'. This is a required feature for doing anything related to navigation.

rendering of maps

How you render OSM files? You split them in smaller pieces or you convert them to a specific format?

Make marker 'movable' by setting location

Add a setter to the maker location.
To show data with a changing location on the map.
To show the changing current location on the map.
...

Bicycle & Pedestrian designation

Fix the interpretation of the designated values in the routing interpreter. Designated does not mean 'only vehicle x'. See wiki:

http://wiki.openstreetmap.org/wiki/Tag:access%3Ddesignated

And add this to the reasons to configure the tags-interpretations for routing more than is currently possible.

Update Android.UI solutions to enable tilted rendering
