QUESTION

Mapbox in Android - Black color around GEOTiff raster layers

Asked 2020-May-28 at 14:11

Goal

I need to add some aeronautical layers taken from FAA to the map. The layers are provided as GeoTIFF files.

Steps

Downloaded a GeoTiff file from FAA website.
Using QGis app clipped the legend from the file. Actually the issue occurs without this step as well.
Reprojected it to EPSG:3857 using GDAL command gdalwarp -q -t_srs EPSG:3857 -dstalpha -of vrt Albuquerque\ SEC\ 104-cut.tif /vsistdout/ | gdal_translate -co compress=lzw /vsistdin/ Albuquerque\ SEC\ 104-north-up-cut.tif. Otherwise I got Error creating Mapnik Datasource: Invalid raster: Invalid rotation value in geotransform array when uploading to Mapbox.
Created a Tileset by uploading GeoTIFFs to Mapbox.
Created a new style in the Mapbox Studio.
Added the tilesets as layers.

Mapbox Studio Result

The map is showing well in Mapbox Studio:

Android Result

However in Android app this style shows with some black borders of random width depending on zoom level and camera position. Here is how it looks in android:

I tried it on Pixel 3a (Android 10), Nexus 5x (Android 8.1) and Android emulator (Android 10). I have good internet connection and gave it enough time so the tiles are loaded.

The source code where the map is embedded is official Demo app. I just replaced token and style URL:

ANSWER

Answered 2020-May-28 at 14:11

The black borders should be transparent, but the raster image format Mapbox is using (JPG) does not support transparency, which is a known issue that exists in every gl-native-based SDK. This issue presents itself when you reference a style that has the raster layer built in.

As a workaround, you can follow Mapbox's troubleshooting guide on troubleshooting raster images with black backgrounds to make your tileset transparent and then add the tileset as a RasterSource within your Android application to display the raster tile as expected.

Please take a look at the following example as a reference for adding a RasterSource:

Add a WMS Source

Instead of calling the rasterSource using "mapbox://username.tilesetID", you need to call it similarly to the Add a WMS Source example. The code below will resolve your issue:

style.addSource(RasterSource( "albuquerque-source", TileSet( "tileset", "https://api.mapbox.com/v4//{z}/{x}/{y}.png?access_token=" ), 256 ))

I worked out how to do this after a while. The issue was that the Fastai model wasn't tracing correctly no matter what shape of input I was using.

In the end, I used another text classification model and got it to work. I wrote a tutorial about how I did it, in case it can help anyone else.

NLP PyTorch Tracing Tutorial

Begin by opening a new Jupyter Python Notebook using your preferred cloud machine provider (I use Paperspace).

Next, copy and run the code in the PyTorch Text Classification tutorial. But replace the line…

QUESTION

Google Ads MediaView not correctly resizing height to wrap_content when displaying image

Asked 2020-Jan-08 at 11:29

I got an email from AdMob today saying:

Change to native ads policy: Native ads will require MediaView to render the video or main image asset. In an effort to help you deliver a better ad experience more easily, beginning October 29th, native ads will require MediaView to render the video or main image asset. Ad units not compliant by this date will stop serving ads, which could impact your ad revenue.

I tried this out in my Android app, removing the separate handling of images with ImageView and video with MediaView, but I have found that the MediaView is not resizing the view's height according to the height of the image it displays.

In this codelab example from Google, a fixed height and width for the MediaView are used. I cannot do this, as this screen is responsive to the screen size, which will change depending on the device. The fact that the image can be dynamically resized is one of the main benefits for using UnifiedNativeAds instead of predefined ads such as banners.

This is how I need to be displaying the MediaView, using match_parent for width and wrap_content for height.

QUESTION

How to show a callout on the map dynamically?

Asked 2019-Jun-05 at 21:07

I am following this example: https://docs.mapbox.com/android/maps/examples/symbol-layer-info-window/

Also here:

https://github.com/mapbox/mapbox-android-demo/blob/master/MapboxAndroidDemo/src/main/java/com/mapbox/mapboxandroiddemo/examples/dds/InfoWindowSymbolLayerActivity.java

It is loading a number of points with descriptions from a file.

On line 271: String geoJson = loadGeoJsonFromAsset(activity, "us_west_coast.geojson");

What I need is to do the same dynamically. I have the information already as features in the map. I can get Title and Description from there. What I need is to use GenerateViewIconTask and setUpInfoWindowLayer when this event is triggered: onMapClick.

So basically a user taps on the map, I get the coordinates and search in the map's features, get the lat/lng, title and description and show up a callout on the map.

I can handle tapping, getting the map's feature, extracting title and description. What I need to do to finish with showing a nice callout on this location with title and description.

Answered 2019-Jun-05 at 21:07

Sorry for the late response. You can either show a label by setting the textfield property or (according to the docs) create an info window by setting the iconImage property to a string, like iconImage("{title}"). Sadly I've rarely used the latter as it never worked for me.
