vtm's Issues

MapEventLayer API improvements

We should complete the MapEventLayer API for all gestures handling.

Remove external git submodule "vtm-ext-libs"

We should remove external git submodule vtm-ext-libs.

Native libraries are better hosted inside the repository for easy control and updates.

vtm-android-gdx example needs stencil buffer

Add stencil buffer to vtm-android-gdx example for working properly.

Mapsforge: heuristic determine for area

Heuristic determine in MapDatabase if a Mapsforge map element is an area.

Enable / update vtm-web modules

Enable / update vtm-web modules to make them working with latest VTM / libGDX.

Canvas resize visual artifacts

We have visual artifacts at canvas resize on desktop, due to improper glClearColor of color buffers.

libGDX 1.9.3 update

• Update libGDX to 1.9.3 with e0f0232.
• Fix API issues in some examples.

VTM iOS native libraries

Add iOS native

License

Is this project still part of the OpenScienceMap project? The license says this.

Mapzen vector tiles

Mapzen tile source will need several improvements and fixes to make it usable.

Mapsforge: deprecate water tiles rendering

Since maps are created properly now with coastlines, water tiles rendering can be deprecated.

Reference: mapsforge/mapsforge#640

Use mesh layer and tessellation option

Use mesh layer and tessellation with option to better handle area rendering.

vtm-jts module

Create vtm-jts module to free vtm core from JTS dependency.

Any third party dependency makes the library less portable and increases the overall footprint. We need to ensure that vtm remains lightweight. This is especially important for being supported e.g. on Android.

VTM native libraries

We should provide VTM native libraries for all supported platforms.

Moving vim-extra into vtm

I wonder, if vtm-extra isn't the same as vtm. Both contain tile sources and other thing. Wouldn't it be correct to integrate vtm-extra into vtm?

Disable doclint in JDK 8 Javadoc

Preparing for the JDK 8 we need to disable in Gradle the strict doclint in JDK 8 Javadoc for the deployment to succeed.

Mapsforge: unread POI tags

In Mapsforge maps the addr:housenumber and ele POI tags are not read.
We should fix that and let the render themes decide the elements visibility.

Desktop keyboard shortcuts

• Use both modifier keys
• Fix rotation and tilt handling

Mapsforge: add sea & nosea tags in render themes

In render themes (for Mapsforge maps):

• Add sea & nosea tags with tessellation
• Remove coastline rendering
• Remove water tile outline

Travis CI

Setup Travis continuous integration.

PathLayer dotted line

hello, I'm glad you've taken over the development of vtm. I'm trying to make a dotted line with the use of PathLayer class with poor results, you could help. thank you

Textures memory leak

We have serious memory leaks on desktop, related to failed glDeleteTextures and depending on libGDX backend and platform.

MapPosition.setByBoundingBox ignores zoom level

MapPosition.setByBoundingBox should update also the zoom level along with scale.

Render themes

Ongoing task for improving render themes.

Remove external git submodule "appcompat"

We should remove external git submodule appcompat.

This is mainly needed for Eclipse builds. Still can be used via Gradle or Maven and maven-android-sdk-deployer.

ViewController doesn't respect movement limits

ViewController.moveTo should respect the Viewport limits.

Vector tile api key

Add parameter for supplying an api key depending on vector tile source.

ItemizedLayer enhancements

Enhance ItemizedLayer API.

Android / AWT interfaces improvements

We could pass here some of the Mapsforge related improvements over the time:

• Retrieve from Android / AWT interfaces the platform classes
• Extend the platform classes API

Gradle and Android updates

Update Gradle and Android to latest versions for using the modern libraries.

Also additional improvements and fixes are needed for the builds to function properly.

Enable / update vtm-ios module

Enable and update vtm-ios module to make it workable again.

vtm-android-start not working

We need to fix vtm-android-start by using a proper application theme.

Mapnik GeoJSON vector tiles

GeoJSON tile source could use some additions:

• Road labels
• Points of interest

According to this note the service will be shut down on August 2016.

Gradle

Refactoring of library's Gradle building, plus various improvements.

Translucent buildings option

Use the translucent buildings with option to better handle the quirks of each platform.

Mapsforge: avoid additional simplification

Avoid additional simplification in MapDatabase besides that existed in Mapsforge maps.
As it seems causing render artifacts and lesser detail on map elements.

Tile grid representation

Change to more common z / x / y representation of debug coordinates, according to file naming conventions for the slippy map tilenames.

Mapsforge: multilingual maps v4

Add support for Mapsforge binary map file format v4 specification, i.e. multilingual vector maps.

Reference: mapsforge/mapsforge#624

Automated Gradle project deployment to Sonatype OSSRH

Implement an automated project deployment to Sonatype OSSRH with Gradle.

Render themes improvements / fixes

The render themes need improvements and fixes to go along with provided XSD.

Improve code / xml formatting

Improve code / xml formatting to modern IDE standards, indentation with spaces, imports optimization, etc.

LineRenderTest show stippled line

Fix LineRenderTest to show also the stippled line example.

Render theme XSD improvements / fixes

The render theme XSD needs improvements and fixes to go along with provided render themes.

Native libraries publishing artifacts

Organize native libraries for publishing artifacts, e.g. Maven deployment.

Render themes: add tessellation option in area style

Add tessellation option mesh in area style at render themes.

XML schema definition position

We should reposition our render theme XSD file in its own separate resources area.

That way it won't be mixed into production jars and also we can use it directly for online validation.

Update vtm-jeo module

Update vtm-jeo module to newer version and recommended repository.

libGDX Android native libraries

Provide libGDX Android backend native libraries.
See #13.

Viewport API improvements

We should add the Viewport API for all movement limits.

Samples

Ongoing task for improving Samples apps.
