Custom Layer integration requires the Commercial Edition of Weather Defender. Contact us for a quote or questions if you are interested in upgrading.



1 - Overview: Dynamic & Static Layers

In Weather Defender, all weather layers, such as radar and satellite imagery, update on a set schedule so you always see the most current data on your screen. These are known as Dynamic layers. Geographic layers, such as roads or cities, do not change frequently and therefore do not need to update on a schedule. These are known as Static layers.

By default, all custom layers imported into Weather Defender will be treated as static. If you are using your own custom data source for Weather Defender that needs to be updated frequently, you can follow this documentation to convert that layer to a Dynamic, self-updating layer.



2 - Creating the Data Source

In order for a layer to be treated as Dynamic, it must be accessible from a URL. This means the source data must be accessible through an HTTP or HTTPS connection. This usually means that the source data will be located on a public-facing website or company intranet.

Once configured, Weather Defender will monitor this URL and automatically download updates when available.



3 - Supported Formats

Weather Defender natively supports the following data formats:
  • SHP, E00, MIF/MID, TAB, DXF, DGN, TIGER, GML, KML, VPF, GDF, SDTS, DLG, GPX, TIFF/ GeoTIFF, JPEG, JPEG2000, PNG, BMP, BIL/SPOT, ECW, MrSID, IMG, CADRG, PixelStore and grid formats (ASCII GRID, FLOAT GRID, BT, DTED, ADF), CSV (x/y table)

NOTE: Weather Defender uses WGS-84, decimal-degree format. If necessary, convert your dataset(s) accordingly.

For more detail on data formats, see the Supported Formats for Integration page.



4 - Adding the Layer to Your Map

  1. Start Weather Defender
  2. On the Map toolbar, click Add Layer (Drop-Down menu) > Add Layer from URL
  3. Enter the URL to your data source (e.g., http://www.domain.com/datafile.csv). You may use CGI/dynamic queries as URLs, as long as the final product is in a supported GIS format.
  4. Press Enter

If the layer has been successfully added, you should see a new button in the Map Layers dialog window:

If you do not see a new button, or if the button has a red cross over the icon, then the import was unsuccessful. Check the file format and try again.



5 - Configuring Dynamic Settings

Now the layer has been successfully added from an online source. Next we need to set the update schedule to finish creating a Dynamic layer.

1. Click the Layer button's drop-down menu, select Properties

2. On the dialog window that appears, click the Updates tab

3. Enter the following settings:
  • Check "Enable Updates"
  • Set the schedule in minutes
  • Under "URL", enter the same URL you entered above.
  • Other settings can be left alone

4. Click OK



If you have the Legend window open, you should see your new layer listed along with a timestamp of last update:

Be sure to save your Map so the new layer is available the next time you start Weather Defender.
