MapHubs

MapHubs is a collaborative platform for sharing and organzing mapping data, and telling stories with maps.

MapHubs is a modern open-source web mapping stack, built with Mapbox GL graphics-based map rendering using vector tiles (https://www.mapbox.com/maps/), PostGIS (https://postgis.net/) and GDAL (https://gdal.org/) for data storage/processing, and Next.js (https://nextjs.org/) and React (https://reactjs.org/) for the web application, along with many other smaller open-source libraries including CKEditor (https://ckeditor.com/ckeditor-5/) for the story editor

Running MapHubs

MapHubs runs as a stack of Docker containers (see list below) using either docker-compose or Docker Cloud

Development

Installing dependencies

git clone [email protected]:maphubs/maphubs.git
cd maphubs
npm install

Local configuration

Before running maphubs locally, you will need to update the environment config variables

• In env/dev/secret copy each of the sample files

MapHubs is made of multiple components: a database, the web application (this project), a vector tile server, and a screenshot service. The easiest way to run everything is with Docker.

Database

The db-server directory contains instructions on running your own postgresql database with the appropriate table schema using Docker.

Vector Tile Server

Screenshot Service

https://github.com/openmaphub/manet-dockerfile

Running

To run the server, use the following command:

npm start

tokml's Issues

ESM import works, but with warnings

When using esm (via vite) the following warning is printed:

▲ [WARNING] Converting "require" to "esm" is currently not supported [unsupported-require-call]

    node_modules/@maphubs/tokml/index.js:1:10:
      1 │ var esc = require('./lib/xml-escape')
        ╵           ~~~~~~~

I actually did import the package like documented in README:

import tokml from "@maphubs/tokml"

and it seem to work. However, I don't like warnings and would very much appreciate to use a really ESM compatible module.

Uncaught TypeError: string.replace is not a function

Hi,

Thanks for working on this. I just migrated from the Mapbox version and my geoJSON is failing to process with

TypeError: string.replace is not a function
at escape (...\node_modules\xml-escape\index.js:11:17)
at timestamp (...\node_modules@maphubs\tokml\index.js:103:64)
at ...\node_modules@maphubs\tokml\index.js:61:13

This was fine with the Mapbox version.

Here's a minimal geoJSON that fails to process:

{
  "type": "FeatureCollection",
  "crs": {
    "type": "name",
    "properties": { "name": "urn:ogc:def:crs:OGC:1.3:CRS84" }
  },
  "features": [
    {
      "type": "Feature",
      "properties": {
        "source": "dji-srt-parser",
        "timestamp": [
          "2017-07-29T05:48:50.000Z",
          "2017-07-29T05:48:51.000Z"
        ],
        "name": "sample2",
        "HOME_LATITUDE": -25.2088,
        "HOME_LONGITUDE": 131.166,
        "ISO": 100,
        "SHUTTER": 60,
        "FNUM": 2.2
      },
      "geometry": {
        "type": "LineString",
        "coordinates": [
          [131.16599999999997, -25.2088, 497.9759216308594],
          [131.16599999999997, -25.2088, 497.9759216308594]
        ]
      }
    }
  ]
}

ESM compability

Using this library fork (which seems to be the most up-to-date one) with Vite / ESM leads to a warning at console:

rebuilt dependencies successfully

  VITE v4.0.3  ready in 1251 ms

  ➜  Local:   http://127.0.0.1:8080/
  ➜  Network: use --host to expose
  ➜  press h to show help
▲ [WARNING] Converting "require" to "esm" is currently not supported [unsupported-require-call]

    node_modules/@maphubs/tokml/index.js:1:10:
      1 │ var esc = require('./lib/xml-escape')

Nonetheless the lib works.

Adding:

{ 
   "type": "module",
 }

...should solve this.

simplestyle attributes should be removed from properties

if simplestyle is enabled, the matching properties should be removed from the <ExtendedData> structure so that they don't also appear in the tabulated list of properties as shown in e.g. Google Earth.
