Hi Gordon,

 

It worked, I also made some adjustments to my boundary box in configuration document in feature source.

 

Regards,

Most images in MapGuide require a georeferencing file or World file.

 

For JPG you may have to create a JPW

(check out this https://iric-gui-user-manual.readthedocs.io/en/latest/06/09_georef.html or google JPG world files)

 

The json should be enough to create the file.

Hi Gordon,

 

I want to display the image on my map, it´s a rain area image. You can download the image using the link https://estatico-redemet.decea.mil.br/radar/2022/09/25/mi/maxcappi/maps/2022-09-25--18:46:27.png.

The images are provided using an API, that returns a json with information about the image: coordinates, link to download, etc. I provided an example of the json return.

I have to create a feature source and a layer to display this image, but I don’t know what type of feature source to use, or type of layer.

 

Regards,

 

Liglio

What is the source of the image? 

Where did it come from?

 

Do you want it to appear as a tooltip or is it geo-coded?

 

where did the metadata come from?
