Advanced data
rer3d-map provides some particular functions that can be used with specific data.
For more information see the TerriaJS guide and the catalog item reference.
rer3d-map can load CSV (Comma Separated Values) files. If the CSV file contains columns lat and lon it's loaded as a layer of points (a point for each row), otherwise it's loaded as a tabular layer without geographic entities.
Example of tabular CSV
x z plant height
1 -1 2
3 -3 4
5 -5 6
7 -7 3
10 -10 9
12 -12 2
Example of CSV of point
lat lon value
-40 140 125
-39 139 365
-38 135 74
-37 145 1428
-37.5 145 0
-37 145.5 4
-40 135 64
In case a catalog item is changes over time, its layer can be updated in rer3d-map setting a polling in catalog definition.
{
"name": ...,
"type": ...,
"url": ...,
"polling": {
"seconds": 20, // the number of seconds to wait before polling for new data
"url": ..., // string of the resource url or path
"replace": true // true if new polled data should replace existing data, false if should be appened
}
}
When a CSV of points is loaded in rer3d-map its appearance is setted using some default values. In catalog you can define display properties adding the tableStyle property. With tableStyle you can define static or dynamic (linked to some CSV column) style. For more information tabular data customizing appearance overview.
Example of CSV catalog item with tableStyle property.
{
"name": "Auto Incidents No Time (CSV)",
"type": "csv",
"url": "test/incidents_notime.csv",
"tableStyle": {
"colorMap": [
{
"color": "hsla(60,80%,80%,1.00)",
"offset": 0
}
]}},
If first column of a CSV is a number or timestamp, its data can be represented as a chart, without any configuration. Chart will open automatically at the bottom of the window. In workench on the left you can choose which columns of CSV draw in chart.

rer3d-map can handle time informations of layers, if any.
If a WMS has time dimension, in its catalog definition you should add showDatetimePicker and useOwnClock properties to use it.
Example of a WMS with time dimension.
{
"name": "Rain Day AU",
"layers": "rain_day",
"url": "http://www.bom.gov.au/jsp/awra/thredds/wms/AWRACMS/deciles/year/rain_day.nc",
"type": "wms",
"maxRefreshIntervals": 9000,
"showDatetimePicker": true,
"useOwnClock": true
}
If a CSV has both lan/lon and time columns, time controls are displayed in rer3d-map interface so you can see and navigate data change over time.
Example of CSV with lan/lon and time columns.
