template for rgbifying AW3D30

I used this package with the following environments:

• Windows 10 Enterprise
• Powershell
• git version 2.25.0.windows.1
• Docker version 20.10.8

This template worked well for the downloaded data as of 29 May 2022.

"ALOS World 3D - 30m (AW3D30)" is available for free download from the following URL. (It is FREE of charge, but please confirm its terms of use.) https://www.eorc.jaxa.jp/ALOS/en/dataset/aw3d30/aw3d30_e.htm

git clone https://github.com/ubukawa/RGB-AW3D30
cd RGB-AW3D30

mkdir src

I succeed developing RGB elevation tiles from 6 zip files. Please consider the number of files thinking about your PC power.

Start Docker container that has gdal related tools and rgbifying tool.

git clone https://github.com/ubukawa/rgbify
cd rgbify
docker build -t unvt/rgbify:ubukawa .
cd ..
docker run -it --rm -v ${PWD}:/data unvt/rgbify:ubukawa
cd /data

Make sure that your working directory is connected to /data.

A directory named 01_unzip will be created, and unpacked zip file will be stored there.

./01-unpack.sh

You will have a sinle tiff file named input.tif. Please consider the extent of the generated file. You will fail if the extent is too large even if the number of donloaded file is small.

./02-merge.sh

Before run it, please modify max-z and min-z or the tile if you want. (default max:11, min:9) You will get RGB tile as out.mbtiles

./03-rgb.sh

Make sure that you do not have "zxy" directory in your working place. Then, run the command. You will get png files under zxy directory. (You can change the output name by editing the script.)

./04-png.sh

Make sure you have zipped 5 by 5 degree data in your src directory. Then, run it.

./all.sh
