The Image overlay is a layer that allows users to upload and display images over the project area in the Tygron Platform.
A much used possibility of the Image Overlay is to import WMS data: geographically referenced data, accessible through an url.
It is also possible to add a custom Image. Keep in mind that the allowed image size for custom images is 1024x1024 pixels. The image must also be in the .PNG format, the Portable Network Graphics format, which is a raster graphics file format that supports lossless data compression.
How to configure the Image overlay
After adding the Image Overlay, the Configuration Wizard can be found on the right side of the screen. This wizard helps with importing the image.
There are three methods to import an Image:
- Import an Image from a file. With this method a custom Image can be imported. Keep in mind that the size of the image should be 1024x1024 pixels and in .png format.
- Import from a Web Image Service. With this method it is possible to import a WMS. Read the corresponding page on how to import WMS data.
- Select an Existing image. This method differs from the first option in that it is now possible to already select an existing (imported) Image from the Tygron Platform to display as an Overlay.
