Open Street Map Web Wizard Usage
Why does a pink screen appear when OSM Web Wizard is invoked from SUMO? I have attached the image below. OSM WEB view page

Tileserver-Gl - Recommended/Required Server Specs for hosting Planet
I was thinking about hosting my personal version of tileserver-gl. What would be the required server specs to just start the server? And what would be the reasonable server specs to serve for example 100 requests of uncached tile requests/s?
Probably the RAM has to be at least the size of the planet.mbtile file to serve content fast? Probably it would be better to even have some room, so
RAM = 1.5 * (size of planet.mbtile)? [This would be currently 64GB RAM or maybe even more?]
When serving raster tiles, one would also need a powerful GPU. Only serving vector tiles should be fine without a GPU?
What is the workflow to pre-render your own openstreetmap raster map tiles (png)?
I discovered openstreetmap a week ago. After reading on the wiki for openstreetmap and other places I have decided that for my project I want to create and upload raster map tiles to my domain. I do not need all the zoom levels and have decided to use zoom level 1-11, which will drastically reduce the size needed for the pre-rendered tile image files, and to present the tiles on the client side using Leaflet. It looks to me that it should be possible to use either the planet file from openstreetmap as a startingpoint (or geofabrik.de), and then aquire a free map style (from somewhere) to use when I render the map tiles for the selected zoom levels.
I would prefer to pre-render the raster map tiles using windows, but if I have to install e.g. Ubuntu that is no problem.
What kind of free software do I have to install and use on my computer in order to create the raster map tiles for the zoom-level 1-11, from the planet osm file. Can I do this directly somehow without having to first import data from the planet file into a database?
How do I specify a map style to be used when creating the raster tiles (png) files, in the above process? Can I use the style used on openstreetmap.org? https://www.openstreetmap.org/#map=11/57.4717/12.0087 Is there a list somewhere, showing a variety of free map styles that one can use for a project like this?
How do I aquire and install the nessesary map style files so the renderer software can apply those that map style to the image tiles produced?
I do not need a specific tile server, in the sense that some special software have to handle the tile request, in order to find out which image tiles to deliver to the client. Since I will pre-render all the map tiles (.png image files), these tiles will be uploaded to a folder on a webhotel, and will just be served the client via requests from Leaflet - which automatically request the correct image file URL's to be used for the selected zoom level and area to be displayed.
From what I can see I do not need to pre-render more than 5 592 405 tiles for the whole world (zoom-level 1-11). I would guess this is will only require around 100 GB of storage.
Why MKTileOverlay repeats same tile over and over for openstreet map in ios, swift4
I'm using OpenStreet map to with our own map server with iOS. for iOS I couldn't find any third party library (free or paid) which can use with our open StreetMap server. then I decided to go with MKMapView using MKTileOverlay like below :
added a MapKit outlet to my storyboard. made a outlet connection and set delegates to self using storyboard and then here is my viewdidload method.
let urltemplate = "http://tile.openstreetmap.org/17/94621/62995.png" let overlay = MKTileOverlay(urlTemplate: urltemplate) overlay.canReplaceMapContent = true mapView.add(overlay)
then the output is like below :
Any idea of what is going on. when I scroll to right of left I can only see this image. please help me with this.
SUMO Traffic Simulation Induction Loops on Multiple Lanes
In the real world, aggregated data from induction loops is usually measured across all lanes of the road. As I try to model traffic demand from real world Data, which holds the number of vehicles that passed a specific induction loop, I wonder what is best practice to place these Induction loops within my net.
Is there a way in SUMO to place an induction loop across all lanes of an Edge ?
Is there a way to group single Induction loops within a higher level XML-Tag and get retrieve the collected data from the group ?
(The background of these Question is the intended use of the DfRouter for multilane Edges)
Different Models in Veins
I've been searching several simulators for moving vehicles and I've found Veins. I was wondering if it's possible to create different models of the vehicles simulated. I mean by that is it possible to create a different type/change the properties of vehicles to create a custom simulation with custom parameters/scenario and custom vehicles?
SUMO: Variable Dijkstra Routing Algorithm
SUMO provides four routing algorithms including Dijkstra. Does it uses variable Dijkstra to avoid congestion on new route? Means whenever a vehicle is rerouted, whole network is investigated again to find shortest / fastest path?
