Things can be measured in google earth, but it is difficult. Theoretically Google earth will display contour lines, but I have not been able to do so.
I found a site called Cyburbia and read an essay on small towns and wild west towns.
there is no standard street width, only approximations. Twenty feet wide for two lanes, about 2.5 inches. Urban streets will be pretty straight, rural roads much less so. Sidewalks vary from place to place. Four feet along quiet streets; ten feet along bustling boulevards. City blocks are determined by the city.
One thing that might be determined by this forum would be the composition of "Edisonvilles," expecting the government to establish residences for thousands of refugees. Thomas Edison created a system of forms to make a house completely out of concrete. Plumbing and even some furniture was molded in. Some basic building structures were also included.
A 16 inch by 16 inch square. The outside border is a 1/2 inch wide sidewalk. The block might have 6 business buildings, separated by alleys, or four residential houses, or one church, or one school. What else do you need in a small town?
Hmmm, I leave new DC and they've recently put some electric streetcars in. I could go check it out some time in person. As far as sidewalk, Scott was talking about the same for his paper terrain stuff. I'll see if I can find it.
Great pic Craig - says me a trip! the Edisionvilles sounds interesting - indeed there should be some large refugee camps of both tent and building types scattered behind lines everywhere up and down the various fronts. I would suspect they'd start as 'tent towns' graduating to simple wood buildings and maybe to stone or concrete later; the later located much further away from any front. I'll have to work up a Martian Harvester raid on one of these 'tent towns' for an OOB! Talk about a good militia type holding action. I'm going to tinker with some balsa wood to see what kind of 'shack' I can come up with for this. I suspect I'll get lazy and just buy some of Achesons 'Shanty Town' resins, as they look to be made up of lots of scrap metals, which would make sense in some ways.
Need to errata the above comments about the 'Shanty Town'. Those excellent pieces are from Ironclad Miniatures line - not Achesons as reported. They have excellent terrain, including the shanty buildings in 15 and 20 mm.
Scott already sells shacks, he might be able to bundle them together in a refugee camp package. Or, check out his civil war tents. These tents look curiously like the same design I slept in in the Cold War.
I am at a point where I can almost start building some streets!
The trick for me will be to set them up to be portable, modular and able to mix and match with my trenches. I picked up some 60 x90 cm mdf boards, but am thinking of trimming them down to 60 x 60 cm to expand my options, and make better use of some of the grass covering options available out there.
