Elevation Profile is a configurable widget that displays the elevation profile for a selected feature or a measured line along with a web map. This is very similar to the Elevation Profile Template (View it live), but with additional functionality. This widget is modeled after the Attribute Table; in that it is docked along the bottom edge of the browser. This widget requires the developer edition of WebApp Builder, version 2.0 or higher.
Elevation Profile is a configurable widget that displays elevation profile for a selected feature or a digitized line in a web map. This template requires an elevation profile service (provided from ArcGIS Online) to generate the elevation values along the profile, and a Line Of Sight service to generate line-of-sight features. Please see the associated Python script that generates the line-of-sight features located in the scripts directory.
This widget will allow:
- Selection of existing polyline features (Popup will need to be enabled in the web map)
- Digitize a line or route
- Display Line of Sight for selected feature or digitized route
This widget requires the developer edition of WebApp Builder. It supports versions 2.0+.
In order to develop and test widgets you need to deploy the Elevation Profile widget directory to the /stemapp/widgets directory in your WebApp Builder installation. In order to add the Elevation Profile Table widget to your developer edition of Web App Builder, please follow these steps:
- Copy the Elevation Profile Table widget directory to /client/stemapp/widgets
- Open /client/stemapp/config.json and add an entry for the Elevation Profile Table widget:
{
"uri": "widgets/ElevationProfiletable/Widget",
"version": "1.4",
"position": {
"relativeTo": "browser"
}
}
- Open /stemapp/predefined-apps/default/config.json and add an entry for the Elevation Profile Table widget:
{
"uri": "widgets/ElevationProfiletable/Widget",
"version": "1.4",
"position": {
"relativeTo": "browser"
}
}
- Open /stemapp/themes/FoldableTheme/layouts/default/config.json and add an entry for the Elevation Profile Table widget:
{
"uri": "widgets/ElevationProfiletable/Widget",
"version": "1.4",
"position": {
"relativeTo": "browser"
}
}
- Add "ElevationProfileTable" entry to /stemapp/widget/list.json.
The LOS toolbox and los.py script should be used as a general guide during the creation of line-of-sight Geoprocessing service. Please make the necessary changes to the script in order to consume your own Digital Elevation Model (DEM) (please look at line 8 of the los.py script).
NOTE: If you intend to select features (instead of digitizing your line), ensure that the web map has pop-ups enabled. This will allow for features to be selected.
