Geocoder Services in Pharo?

Hi Sven,

thanks for your fast response and the snippets. I scanned the different geocoder classes from "geopy" and also the OSM Nominatim docs. Indeed, it is not hard, ..... but if there is already a package, why not using it :-)

maybe i start to write such a lib.

Thanks,
Volkert

As far as I know there is no such library.

We have it internally, but that part is not open source. But it is not so hard to do yourself.

Here is an example for forward geocoding (address -> coordinates):

ZnClient new
        url: 'http://nominatim.openstreetmap.org/search';
        queryAt: #format put: 'json';
        queryAt: #addressdetails put: '1';
        queryAt: #q put: 'Villerspark 5, 3500 Hasselt';
        queryAt: #countrycodes put: 'be';
        accept: ZnMimeType applicationJson;
        contentReader: [ :entity | STONJSON fromString: entity contents ];
        get.

Here is an example for reverse geocoding (coordinates -> address):

ZnClient new
        url: 'http://nominatim.openstreetmap.org/reverse';
        queryAt: #format put: 'json';
        queryAt: #lon put: 5.33732 asString;
        queryAt: #lat put: 50.926 asString;
        accept: ZnMimeType applicationJson;
        contentReader: [ :entity | STONJSON fromString: entity contents ];
        get.

These are against the OpenStreetMap Nomatim service, others are similar.

HTH,

Sven

of course :-)

yes, i am trying to load the package GADM in Pharo 5, but it failed  ... :-(

Then what would be good is to code it as open-source so that people can join effort. 

Did you check the packages of geolocalisation developed by Hernan Morales?

Dear Hernán,

cool, really nice work. will have a closer look :-)

It really is too bad, that it is so hard to find such cool packages. i im really missing a kind currated list of all the cool pharo packages around. somthing like awesome python, f.e. "https://github.com/vinta/awesome-python"

BW,
Volkert
PS: Btw, loading the OSM support package failed (following the instruction on Page 45 of your docu).

Hi Volkert

Territorial (https://github.com/hernanmd/Territorial), is a library for geographical information retrieval. GADM is included in Territorial but is mainly for boundaries. The feature you ask for is not there yet, but if you want to try out other features or look for integration you can install it by doing:

Metacello new
  smalltalkhubUser: ’hernan’ project: ’Territorial’;
  configuration: ’Territorial’;
  version: #’development’;
  load.

We will have a nice look and make sure that people can print them in spiral format.

if you want Territorial to be in let me know.
