Creare una mappa custom con QGIS, evidenziando le aree verdi sulla basemap di Carto

QuickMapServices è un plugin molto utile che offre molte basemaps. Per creare una mappa “con stile” però bisogna approfondire di più questi strumenti. Infine con alcune operazioni sui vettori e l’utilizzo dell’Atlas, è possibile ottenere delle mappe per rilievi “ad hoc”

15 Creative Maps Made with the New CARTO.js 4.0

Developers need open-source tools to be able to create applications that are both visually stunning and highly functional. CARTO and the Location Intelligence community have long supported the open-source community, contributing to the development of a modern geospatial tech stack that allows all companies to take advantage of their location data.

Today we’re excited to announce a beta release of CARTO.js 4.0.

CARTO.js is an open-source JavaScript library that interacts with different APIs in the CARTO Engine ecosystem. The new version, CARTO.js 4.0, provides additional functionality to extract and filter data within CARTO so that you can create custom UI components, such as widgets, pop-ups, legends, and much more.

If you have used previous versions of CARTO.js, take a look at the Beta Release documentation to learn more about the basic concepts and workflow changes between the old and new library.

The current beta of CARTO.js includes changes to the JavaScript library only. A future enhancement will include functionality for maintaining your core application.
