The most popular map browsers available (e.g. Leaflet, OpenLayers) require you to call JavaScript libraries from your page. This assumes some knowledge of JavaScript. The MiraMon Map Browser is designed in a way that does not require the user to have any knowledge of coding. Instead, the JavaScript code interprets a config.json file that configures all aspects of the browser in a declarative way, including distribution of the elements in the screen as well as the list of data layers and services shown. The use of the MiraMon Map Browser is expected to edit the config.json only.
Our aim is to support as many OGC web services and OGA API standards as possible. The Map Browser can be used to present and analyze information coming from standard OGC web services from any vendor. However, we also experiment with extensions of the OGC standards, and this can be obtained by combining the Browser with the MiraMon Map Server CGI. The most significant example of extension that we promote is the use of WMS with binary arrays.
General information about the main functionalities of the map browser here: https://www.miramon.cat/ENG/Prod-NavegadorServidor.htm
The code of the map browser is in the SRC folder. To test it, you can set a copy of the SRC folder in your web server folder (for example, in Windows IIS, folder in C:\inetpub\wwwroot\MiraMonMapBrowser). The landing page of the browser is called index.htm. The code of the MiraMon Map Browser can be used with no modification.
The MiraMon Map Browser can be configured to your purposes populating a file named config.json. The SRC folder does not contain a config.json file to prevent accidental loss of your instance configuration when updating. Several examples of config.json documents can be found in the examples folder. You can request a Windows application called Adm_MMN.exe to edit some parts of config.json in a more user friendly way by sending a request to [email protected] (unfortunately this application does not allow configuring the recent functionalities).
The config.json data model is described and can be validated using a json schema file
It is also possible to load a config file with a different name by calling the landing page with the extra parameter index.htm?config={name-config.json}
