从 kotlin 或 java 中的 srtm dem 文件获取坐标的高程

Question

I want get elevation of point offline in my app I searched a lot but could not find a library for this.How can I do this?

We have a dem file and we may get altitude from that

Answer 1

This library seems promising: https://github.com/komoot/batch-dem-reader

This Kotlin app also seems relevant: https://github.com/raynigon/raylevation

If none of the options give you what you need, you'll probably have to implement parsing the file yourself. For that, you can get inspiration from libraries written in other languages (eg https://github.com/tkrajina/srtm.py )
