Datasets

This app works with data of two datasets (currently hosted on HuggingFace repository):

• global-elevation-aster-slippy-tiles-tar-gz contains the ASTER elevation dataset with a clever compression algorithm, retiled according to the slippy tiles convention.
• global-openstreetmap-extraction-slippy-tiles-tar contains data extracted from OpenStreetMap, also retiled according to the slippy map convention.

Build

To build the project, follow these steps:

• Download the Liberation Fonts .ttf files and extract them into the ./assets/liberation_fonts/ folder.
• Convert all .svg files located in ./assets_nonshared/icons/ to .png format, and place the resulting files in the ./assets/icons/ folder.
• Create an Apache Lucene search index for geographical names and store it in the ./assets/geonames_index.362/ folder.
  • Use Apache Lucene version 3.6.2 (the last version compatible with Android).
  • Include the following string fields in the index: name, asciiname, lat_store, lon_store, and population_store.
  • Refer to ./core/src/test/java/TestLuceneGeonames.java for an example of how to generate the index.
• Build the project with Gradle — this process is straightforward when using Android Studio, and supports both Android and Desktop builds.
