Much of the action in SF roleplay games takes place in ships, on space stations, and in ground facilities. In some cases commercial and fan scenarios include maps, but games masters will often need maps of their own.

This page details two webpages I have developed to list ("Geolist") and display ("Geoplot") geomorphic tiles so that you can develop detailed maps.

Please carefully note the copyright and licence information at the bottom of the page.

Robert Pearce has addressed this need with his excellent Starship Geomorphs for Traveller.

This book contains over a thousand rectangular tile that can be printed and butted together to make extensive highly-detailed maps.

Eric Smith saw Robert's files and converted them to transparent .PNG format so that they could easily combined using an image editor program. Details are given on this gurpsland page by Eric.

Geolist lists the tiles (the high res print ones from rpgmorbius) and allows you to filter them by keywords. The keywords are in the filenames of the original tiles, which I have renamed with shorter titles.

For example, '101 [100x100] Multipurpose (Offices, Fuel, Engineering, Medical, Escape Pod, Staterooms, Galley & Mess).png' is renamed to '101A.png'.

Filtering by 'cargo lounge [100x100]', for example, will reduce the list to about 28 tiles. All of these will contain 'cargo' 'lounge' and '[100x100]'.

Geolist will show thumbnails of the tiles if there are fewer than fifty in the filtered list.

You can add some URL elements to change the scale of the thumbnails, by adding 'size=' and a number. For example like this:

• https://www.iandrea.co.uk/sf/geo/code/geolist.html?size=500 - for large thumbnails.

• https://www.iandrea.co.uk/sf/geo/code/geolist.html?size=50 - for tiny thumbnails.

You can also use 'filter=' to predefine the filter. Use '%20' to separate terms.

Example: show the tiles with 'arboretum' and '[50x50]' keywords, using small thumbnails:

• https://www.iandrea.co.uk/sf/geo/code/geolist.html?size=30&filter=arboretum%20[50x50]
