Esri Landscape Modeler

Landscape Modeler is a sample JavaScript web application that demonstrates how to perform site suitablility analysis by leveraging the landscape data hosted on ArcGIS Online and the speed of image service raster functions. This is ideal when a users want to test and share their ideas about suitability or risk analysis models at multiple scales or over a large area.

View it live

Landscape Modeler is built on top of the ArcGIS API for JavaScript and ArcGIS Server image services. By default it is configured to use the ready-to-use landscape layers on ArcGIS Online. However, the application can be configured to use other data that is exposed as an image service published with a weighted overlay raster function.

Features

Landscape Modeler allows any user with a valid ArcGIS Online organizational account to:

• Design weighted overlay models using the ready-to-use landscape layers on ArcGIS Online.
• Run those models in real time at a variety of scales and extents.
• Save models as ArcGIS Online web maps that can be loaded into other applications or ArcGIS for Desktop.
• Load and view models that have been saved and shared by others.
• Overlay the model with a feature service and see graphs of model results by feature type.

Instructions

Using the Application

See the Landscape Modeler Help for instructions on how to use the application.

Development Instructions

1. Fork and clone the repository
2. cd landscape-modeler-js
3. npm install for Grunt/Karma

See the wiki for instructions on configuring and deploying the application.

Configuring the Application

If you wish to configure the application to use a different weighted overlay image service (i.e. your own data), see the Configuring the Application to Work with Other Data page of the wiki.

Requirements

• Must be configured to point to an image service that exposes weighted overlay raster functions
• If you plan to host the weighed overlay image service, it must be running on ArcGIS Server v10.2 or greater

Dependencies

Runtime

• ArcGIS for JavaScript API v3.5 or later

Development (optional)

• Karma (for running tests)
• Grunt (for builds)

Landscape Modeler was developed along with GeoPlanner for ArcGIS by a team comprised of members from both the ArcGIS Content and Professional Services divisions at Esri.

Landscape Modeler is based on work done by the Esri Application Prototypes Lab and the Esri Imagery Team to create applications that perform fast weighted overlay analysis by leveraging ArcGIS Server image service raster functions.
