Open Topo Data lokaler Server auf MacOS

You can run your own DEM server on macOS. Open Topo Data has a free git project for this purpose. All GDAL compat- ible GeoTiffs can be used. First, install Docker (apple-silicon Docker). Create a local project directory without iCloud. The datasets should not be in the cloud (GB of data). Do not use your doc- ument folder (iCloud /Users/<your name>/Documents/). /Users/<your name>/Project/ cd /Users/<your name>/Project/ When using multiple computers, there may be problems with the cloud directory in Docker. Therefore, it is better to create a project directory outside the cloud. git clone https://github.com/ajnisbet/opentopodata.git cd opentopodata Edit Makefile and change port. Port 5000:5000 is occupied by MacOS. run: docker run --rm -it --volume "$(shell pwd)/data:/app/data:ro" -p 5100:5000 opento- podata:$(VERSION) daemon: docker run --rm -itd --volume "$(shell pwd)/data:/app/data:ro" -p 5100:5000 opento- podata:$(VERSION) run-local: FLASK_APP=opentopodata/api.py FLASK_DEBUG=1 flask run --port 5100 Create config.yaml (copy of example-config.yaml) # 400 error will be thrown above this limit. max_locations_per_request: 400 access_control_allow_origin: "*" datasets: - name: swisstopo-2m path: data/swisstopo-2m/ filename_epsg: 2056 filename_tile_size: 1000 Now the build can be generated. make build-m1 make run

Local DEM server with iPhone and iPad

The local IP address of the MacOS computer can be displayed using ipconfig getifaddr en0 for WLAN or ipconfig getifaddr en1 for Ethernet. The firewall must allow com.docker.backend as an APP for incoming connections. The local DEM server uses port 5100. Port 5000 is occupied by macOS. Other ports that are not occupied by macOS can also be used. To do this, however, the Makefile or config.yaml file must be modified. This makes it possible to access the DEM server via iPhone or iPad on the local network. The address for the local DEM server on the iPhone/iPad then looks like this, for example: http://192.168.0.125:5100/v1/swisstopo-2m Here, 192.168.0.125 is the IP address of our Open Topo Data DEM server, which can be read out with ipconfig.
