3 Illustrations Geothermal Energy

I need three graphics as illustrations for a book. I have searched for examples on the internet. They have to be drawn in a way that does not violate the copyright. All three pictures have to be in Greyscale. Everywhere all letters must be removed, so that one can label the pictures also in different languages. The scale with the temperature information in the first picture has to stay of course. With the first picture I want more abstraction. At the second one I want to adjust the scale so that there are still temperatures on the scale, which are not to be found on the map. Please show 40° C (violet) as white and 140 °C (orange) as black. In the last picture I need an earth surface, so that one can distinguish what is under the earth and what is above. Please show blue (cold water) as white and red (warm water) as black. The background should be white or transparent. Also, the plant on the ground should be represented differently.
