Perhaps the card format is not the best for this and a bigger format could be better. Still this cards pack a mean punch with adventure locations, a blacnk map on one side and a GM one on the other with location highlight text and numbers that have the correponding descriptions. These cards are designed with sci fi in mind, providing locations with more angular feeling and mixing some that can be used as planetary bases or camps and some that can function either as inside of buildings or building blocks for a spaceship.
Quite a good addon for your GM resources that can provide either a quick location or help plan in advance more complex escenarios combining several of them.
Keep in mind that the maps are abstract, so that you can use and reuse with different story details for skinning.
