mapproxy-hips 0.2.0

快速入门

python3 -m venv myvenv
source myvenv/bin/activate
pip install mapproxy_hips

git clone https://github.com/rouault/mapproxy_hips
mapproxy-util serve-develop mapproxy_hips/hips_examples/ogc_as_hips/mapproxy.yaml &
curl https://:8080/hips/mars_tiled_geodetic/properties

添加HIPS服务

公开HIPS服务（即MapProxy的输出作为HIPS）需要在MapProxy配置文件中的services下声明hips项目。

services:
  hips:
    #resampling_method: nearest_neighbour
    resampling_method: bilinear
    #resampling_method: bicubic
    # populate_cache: false

并且通常需要为每个公开的图层自定义HIPS元数据

layers:
  - name: my_layer_name
    title: my title
    sources: [my_source]
    md:
        hips:
            # enabled: false
            creator_did: ivo://unknown.authority/some_id
            obs_title: Some title
            # foo: bar
            # hips_tile_width: 512
            # hips_order: 5

实用工具

可以使用的mapproxy-util脚本的hips-allsky命令可以生成某些HIPS消费者所需的全部天空文件。

Usage: mapproxy-util hips-allsky [options] -f mapproxy_conf -l layer

Options:
  -h, --help            show this help message and exit
  -f MAPPROXY_CONF, --mapproxy-conf=MAPPROXY_CONF
                        MapProxy configuration.
  -l LAYER, --layer=LAYER
                        Layer
  -o NORDER, --norder=NORDER
                        Order
  -c CONCURRENCY, --concurrency=CONCURRENCY
                        number of parallel processes

可以使用的mapproxy-util脚本的hips-seed命令可以预先生成HIPS瓦片。

Usage: mapproxy-util hips-seed [options] -f mapproxy_conf -l layer

Options:
  -h, --help            show this help message and exit
  -f MAPPROXY_CONF, --mapproxy-conf=MAPPROXY_CONF
                        MapProxy configuration.
  -l LAYER, --layer=LAYER
                        Layer
  -o NORDER, --norder=NORDER
                        Order
  -c CONCURRENCY, --concurrency=CONCURRENCY
                        number of parallel processes

添加HIPS源

添加HIPS源（即HIPS作为MapProxy的输入）需要在源声明中指定类型：hips，并指定HIPS服务的URL和图像格式。

sources:
  mars_hips_source:
    type: hips
    image:
      format: image/jpeg
    resampling_method: bilinear
    url: http://alasky.u-strasbg.fr/Planets/Mars_MOLA
    # cache_hips_tiles: false
