Regenerative travel is easy to adopt, simply start following the Regenerative Travel Essentials above and you can be a Terraformer Everyone is at different points of their own journey to become a responsible planetary steward, start here and chart your personal route to becoming a Terraformer.

You can also convert data between different formats like ArcGIS Geometries and Well Known Text. You can use multiple types of spatial indexes and backing stores for your data. Terraformer GeoStore is a JavaScript database for indexing and querying large amounds of GeoJSON. Start exploring all the options you have working with Primitives and the core library. bbox () // returns the geojson bounding box for this object. within ( convexHull ) // returns true var boundingBox = polygon. You can also have Terraformer perform many geometric operations like convex hulls and bounding boxes. insertVertex (, 2 ) // figure out if our point is within our polygon point. add a new vertex to our polygon polygon.

Now that you have a point and a polygon primitive, you can use many of the primitive helper methods. You can create a new Terraformer.Primitive with any GeoJSON object. Most of the core Terraformer libray centers around using Primitives, which wrap GeoJSON objects and provide additional functionality. To see Terraformer in action in the browser, check out our live demos. To utilize supporting packages, you must load their source as well. To use the Terraformer library, include a reference to it using a tag. require ( 'terraformer-arcgis-parser' ) require ( 'terraformer-wkt-parser' ) require ( 'terraformer-geostore' ) Link If needed, supporting packages can be added too. Var Terraformer = require ( 'terraformer' )
#TERRAFORMERS BATH INSTALL#
Install the core module with NPM and then require it in your Node program. GeoStores also need an index module and a backing store which are distributed as separate modules. GeoStore - A JavaScript database for storing and querying collections of GeoJSON Features.WKT Parser - Parses basic WKT (Well Known Text) strings to and from GeoJSON.ArcGIS Parser - Parses ArcGIS geometry objects to GeoJSON and vice-versa.
