How to implement spherical environment map with 360 degree texture in OpenGL?

When we create cubemap in OpenGl, we need six images and with these, we can create cubemap. (simply put, GL_TEXTURE_CUBE_MAP)

At first, I guessed there was similar parameter such as GL_TEXTURE_SHPHERE_MAP, but I could't find any thing related to it.

I wonder how we can create spherical environment map with 360 degree images?

(If you know the site about that, please link for me)

Load the image as a regular 2D texture and do spherical texture coordinate mapping in the shader.
