I am working on a portfolio in QGIS. One idea I had was comparing a bike network(San Francisco) to elevation, to show what bike routes were the steepest and most difficult for bicyclists.
I found a perfect dataset from UC Berkeley of SF's bicycle network that works with OpenStreetMap, but now I need to find an elevation map/layer. Its a been awhile working with QGIS, so I have forgotten a lot of things.
My goal is:
-find a bicycle network file of SF(did that, imported it)
-find a topographic/elevation map San Francisco(I'm struggling using USGS to find what I need)
-then use the elevation layer to rank areas of the bicycle network by elevation/steepness. For example, bike segments that in are very steep areas will be shown in red, flatter parts in green. Not sure how I will do that part.
Sorry if this doesn't belong here, but idk which sub would be better.
Does anyone know of a good road map generator? I've been wanting to draw a map of a small, modeen day down, but I'm not good at roads...
This is no longer available! (can be selected but map doesn't show - trails and towers do) Known issue??
Back before Google and Apple came to dominate the online mapping world, there was a small-ish British website called streetmap.co.uk. It's still out there, and one of the things I really like about it is that it displays roads in the proper colours (blue for motorways, green for trunk routes, etc).
But that's besides the point. It also seems to have some very strange sources of data. For example if you look at this map of Manchester it shows you "Manchester Liverpool Road railway station".
The thing is, that station closed in 1844.
What on earth are streetmap using as their source of data to get that in an online map?!
The cost of these two files is $3,500 for NA, and $3,000 annually for Streetmap from ESRI. I am interested in these primarily to do drive time analysis (DTA), that this a lot of money. I have the base ArcGIS for desktop already. Do I have options for doing DTA other than forking over $7,000CDN to ESRI? Are there add ons I can use instead?
Hello all, for a while now I've been fascinated by a Processing art project I ran across many years ago called Substrate.
I would like to try to make something in Python that would do similar, but I have literally no idea where to begin. I've been all over the PG wiki in the sidebar, and it all looks very high level, and I have to admit I don't understand much of it.
I don't know what the particular method used in the application is called, I've read stuff about Perlin Noise and Cellular Structures that seem like maybe they'd be a way to go. I'd like it to be graphical, but I also have only an intermediate understanding of Python in the first place, so that may be ambitious right now.
I did find the Processing source code here. I've read it through, but it doesn't give any clues I can find toward how it generates this effect, or if it is indeed procedural.
Anyone who can give me some direction in which to research? Which method may be used, and python resources for procedural generation?
Hey, hoping some of the city re-creators can help me out! So I've used terrain.party to get a heightmap of a city I want to rebuild and I've got the mod that allows me to overlay an image on top of my map so I can copy the street layout...
But I have no clue where to get a streetmap of that size, since with google maps if I zoom out to 18km x 18km I can't see all the smaller roads, and I would like to use the exact coordinates for the corners of the box so it aligns with the heightmap.

Not sure if anyone is interested, but a few years ago I got it into my head for some reason to try and make Ankh-Morpork in Morrowind's engine. I guess I had a lot of free time in college.
Anyways, I didn't get beyond making the basic streetmap in the construction set before realizing how enormous a 1:1 scale Ankh-Morpork would be. Some of the buildings were so large, they spanned more than 3 in-game cells, which caused strange visibility issues if you wanted to generate distant land and statics, which is tough to get working. I made that streetmap by grayscaling and flattening a map of Ankh-Morpork, then running that through a program called TESAnnwyn to generate a heightmap compatible with the game engine, with the river carved out and the streets outlined. Here's that image. And then I combined the output with a couple of 'blank.esp/esm' files that I think I found on TESNexus for starting an empty construction set project; this .zip has those files.
And the end result? Well, it's...very empty. But maybe someone will be interested; at the very least it's a testament to the engine's moddability.
Project I'm working on, need a street map of IRL Woodinvile I can easily modify, as I'm trying to recreate/improve the transportation system it the city itself, in the best simulation I can think of. Issue is, I suck at this, and even more so I have no idea how to recreate a real map in C:S.
Some background: In the comments here at transhumanism, user eleitl has included a link to an excellent article on connectome research called The Strange Neuroscience of Immortality. The article follows Kenneth Hayorth's work in connectome research, and makes a very strong argument for the possibility that your consciousness can one day be emulated using a detailed map of all neurons and connections within your brain.
I very much recommend reading it.
But now for my problem: The article also contains one very strong analogy as to why hosting a consciousness within a connectome will never happen:
The Baylor neuroscientist David Eagleman offers an analogy. Suppose that an alien creates a perfect street map of Manhattan. Would that explain how Manhattan functions and what makes it unique? To answer those questions, he says, the alien would need to see what's happening inside those buildings, how people are interacting. Dropping the analogy, Eagleman says, "Maybe we need to know the states of the individual proteins, their exact spatial distributions, how they articulate with neighboring proteins, and so on." To understand the brain well enough to copy it, neurons might be insufficient.
"Neuroscience is obsessed with neurons because our best technology allows us to measure them," Eagleman says. "But each individual neuron is in fact as complicated as a city, with millions of proteins inside of it, trafficking and interacting in extraordinarily complex biochemical cascades."
To me this analogy really takes the wind out of the sails of connectome research for the purpose of hosting a human consciousness: A perfect map of the neurons in your brain, all triggering exactly the same way as they would in your real brain, does not seem to account for the complex chemical and protein interactions occurring behind the scenes.
Is there any insight as to why this analogy may be flawed in some way?
EDIT: (3 days later) ...................
Reading your posts and thinking more on this, I realized the best part about the Manhattan analogy is it demands more from the connectome. A map is not enough. For starters, there's no way you can make an accurate brain without making an accurate body to go with it.... all of your emotional cues come from it... for instance, how would you tell a connectome that it just

Wondering if anyone has a solution to this problem. I use ArcMap and StreetMap premium for market research. There's a couple data sets in StreetMap that I can't get to work correctly. POI is a set of addresses. In ESRI's infinite wisdom, they decided to not put the street name into the POI table (even though they included house number, zip, etc), instead using the Link ID to match them. I've tried joining the tables to export the POI subset as a new layer with the street name included. However, ArcMap crashes whenever you try to open the attribute table or do anything else with it. Anyone have any suggestions?
Hi there, I have to geocode thousands of California addresses but I'm not finding the StreetMap US Locator in my computer. Does anyone know if there is a way to download it? Should it have come with the ArcMap download?
The locator services that come on the geocoding toolbar are World Geocode Service (ArcGis Online) and MGRS. I tried World Geocode Service but the criteria do not match the fields in my address table. The criteria are Address, Neighborhood, City, and Subregion. I have Address, County, Zip code, and Tract #.
But more importantly, any information on getting StreetMap US Locator would be a huge help.
Thanks,
Penny
