Creating accurate maps

Posted by Mike Moresi on 19 May 2016 in English (English)

I'm very new to the OSM community. I signed up a few days ago and have focused primarily on where I grew up (Klamath County, Oregon) and where I live now (Eugene, Oregon) and it is surprising how little is accounted for throughout Lane County and Eugene given the population base.

I have the privilege of working at the University of Oregon and in close proximity to the department of Geography. I asked a couple colleagues there about their opinions on OSM and some affiliated products like Mapbox. Their responses to me were--in short--not very positive.

Their response made me wonder why: Why is it that the map is so incomplete? Do people want to have a say about their areal knowledge? Do they even know this project exists? As someone who has a natural affinity toward cartography and accuracy within the field, I never knew how easy it was to impart that knowledge to the world until a couple days ago; so I answered my own question. It seems like the large, resource-rich companies like Google, Microsoft, Apple, and others produce a product that is good enough for most. Perhaps I'm more pedantic in cartographic precision--and as much as I like how Google and Bing Maps have progressed--I'm not fully satisfied; local knowledge of place is key to add and it is essential for making maps more meaningful to all involved in creation and consumption.

Upon logging on this evening, I came across marczoutendijk's post which grieved over the same sentiment. Accuracy and prominence of places within the project are still hazily defined if at all and this project is far from being user-friendly. Soon, I hope it can improve. It must improve.

I'm excited to continue to work on this project to the best of my ability and I wish to learn from the greater community about how to improve my skills specifically and the project more generally.

Now the Computer Has Died

Posted by alexkemp on 18 May 2016 in English (English)

I've been giving JOSM a lot of grief. I think that this is because it is written in Java, and my webmaster experience has caused me to be deeply suspicious of Javascript (don't bother writing; I'm well aware that they are different beasts).

A few days ago, whilst about to create a new terrace in City Heights, Mapperley, I selected a node in a building rectangle inside JOSM. It turned blood-red, which was perfectly normal. Then the whole screen turned the same colour, whilst the only key that the computer responded to was the electricity supply on/off button; that was perfectly abnormal.

To cut the long, horrible story down to size, it was not due to JOSM, but was rather because one of the two 2GB memory sticks that were bought a few years ago from Crucial had gone bad. When memory touched ~411MB the whole system died, and the entire screen was left painted the same as the last pixel used. (Added later: a phone call to Crucial and collect a Freepost address + RMA number to return & they will send two new replacements; that's what a “Lifetime Guarantee” means, even though they were bought in 2011.)

Using memtest86+ caused the same shutdown. Removing the 2 sticks (leaving the original 1GB memory in place) removed the problem. Bum.

Fixing the problem is the easy part (a new Lenovo H30 from PC-World - strip out the useless Windows10 & replace it with Debian Jessie 8.4 & we are away) (why on earth am I forced to pay for Windows?). Moving all my stuff from the old computer to the new is the difficult bit.

How To Install Debian on a modern AMD Desktop Computer:

Some truly geeky stuff for anyone else with similar equipment & problems, to try to help; first, my target system:-

  1. Lenovo H30 / Windows 10
    (is discontinued on Lenovo site; thus very cheap on PC-World)
  2. AMD A8-6410 APU
  3. EFI boot
  4. “F1” to access BIOS

Fortunately, I obtained a brand-new Jessie (Debian 8.4) ISO file to install. That is necessary as the H30 has the BIOS within a hdd partition + boots from a EFI partition (I believe that this was introduced at Windows 8.1). Debian will handle all that transparently on install; just as well for me as I was ignorant of it until afterwards, and may otherwise have tried to use an ancient Wheezy Live-Boot USB Stick.

a) Debian Basics

  1. It has a user/superuser system
    (the user always logs in under their user-name)
    (the ‘root’ superuser is used only for administration)
  2. “Stable” is the first of 3 possible distributions
    (currently called ‘Jessie’, it is the least buggy distro)
  3. “Testing” is the next distribution
    (currently called ‘Stretch’, it will eventually become the “Stable” distro)
  4. “Unstable” is the final option
    (always called ‘Sid’, it will eventually become the “Testing” distro)

The Debian links below often show ‘8.4.0’ in the URL. That is the current version of Jessie. As Jessie gets updated, those links will break (the version will become ‘8.5.0’, etc.).

b) Create an Install Stick

You need:

  1. 2GB USB Stick
    (all contents will be wiped)
  2. Debian ISO file
    (Install Help)
  3. An Internet Connection via Ethernet
    (anything other than Ethernet may need drivers installing, which may not come on the stick)

I downloaded debian-8.4.0-amd64-CD-1.iso (630 MB). With hindsight, because I was going to use the lightweight-XFCE4, I could have downloaded debian-8.4.0-amd64-xfce-CD-1.iso (646 MB). It did not actually matter, as I was asked what Desktop Manager I wanted to use during install, and chose ‘xfce’ at that point. The issue in all cases is that you only need CD1 (unless you do not have an internet connection for the machine).

The ISO needs to be printed upon the USB stick (or CD if you decide to go all old-school). Here is how to do it from a Linux terminal:

  1. Check that the downloaded ISO has the correct md5
    (also download MD5SUMS file)
  2. Put USB stick in computer & check it's device name
  3. Use dd to transfer to the USB stick

So, the first thing is to check the md5 for the downloaded file (this guarantes that the entire file has downloaded intact):

alex@home:~$ cat Downloads/MD5SUMS | fgrep debian-8.4.0-amd64-CD-1.iso   
c58a9df992d6e119121babbac9bb5a13  debian-8.4.0-amd64-CD-1.iso   
alex@home:~$ md5sum Downloads/debian-8.4.0-amd64-CD-1.iso   
c58a9df992d6e119121babbac9bb5a13  Downloads/debian-8.4.0-amd64-CD-1.iso   

md5 is correct, so now check the newly-inserted usb-stick:

alex@home:~$ lsblk   
NAME   MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT   
sda      8:0    0 931.5G  0 disk   
├─sda1   8:1    0   512M  0 part /boot/efi   
├─sda2   8:2    0 923.6G  0 part /   
└─sda3   8:3    0   7.4G  0 part [SWAP]   
sdc      8:32   1   1.9G  0 disk   
└─sdc1   8:33   1   1.9G  0 part   
sr0     11:0    1  1024M  0 rom

The stick is auto-mounted in /media if formatted. dd needs to be used on an unmounted device:

alex@home:~$ sudo umount /dev/sdc1
[sudo] password for alex: 
umount: /dev/sdc1: not mounted

(the stick is not formatted)

alex@home:~$ sudo dd if=Downloads/debian-8.4.0-amd64-CD-1.iso of=/dev/sdc bs=1M
630+0 records in
630+0 records out
660602880 bytes (661 MB) copied, 408.09 s, 1.6 MB/s

That is a terrifying command to get wrong! As you are working as root ('sudo') it will allow you to shaft any part of the computer that you want. Note that 'if'=='in-file', 'of'=='out-file', 'bs'=='chunks of bytes to transfer at a time'. When the usb-stick stops flashing & the final 3 lines above are printed, the stick is ready to use.

Now to get the computer ready:

c) Install Debian into the H30

Warning! This deletes absolutely everything from the Hard Disk
(Possibly the Recovery partition is left, but I haven't tried to check)
(The BIOS untouched)

You may receive the following message on startup with the USB stick in the slot:

Secure Boot Violation
Invalid signature detected
Check secure boot policy in Setup

The H30 was shipped set to “Quiet Mode”, so no messages came up ordinarily at bootup. Even the telephone Customer Support was unsure of the command to get into Setup (it is 'F1') (no quotes) (you will need to be very quick as it is a very short bootup). You will find the Secure Boot Policy in there, which stops anything else other than the existing OS from booting. Set it to “Disabled”.

From that point, just follow the prompts to install Debian (very, very simple).

d) Final Setup

To perform any admin, at the moment, means switching to the root user. If you use the terminal a lot you will want to use 'sudo' (“superuser do”) instead. Here is how: (in a terminal):

alex@home:~$ su
Password: 
root@home:/home/alex# adduser alex sudo

“su” is the “switch user” command (default: switch to root), which then needs the root password. The final line puts the user into the “sudo” group. From that point on, entering ‘sudo’ in front of a command (will require one's own password the first time) will perform the command as the root user.

The H30 has hardware that does not have Open Source drivers. It does have drivers for Linux (Debian), but those drivers come as pre-compiled binaries from the manufacturer, and the source-code is not available. For that reason, Debian refers to the sources as “non-free” (even though there is zero financial charge) (all that sort of stuff gets up my nose as well, but I put up with it since my Synaptic currently has 42,981 packages freely available, many of which are best of their class).

The main problem was that – for whatever reason – that Debian sets up the Update (“Repository”) system only with a ‘main’ repository which, as explained in the previous paragraph, means that the system will not have certain vital systems working. In my case that was Bluetooth, which is absolutely classic. It is easily fixed.

The easiest way to fix this is via Synaptic (graphical update utility) (use Menu: Settings|Repositories|Section(s)). However, being GUI means that I cannot show you here. So, using a terminal:-

alex@home:~$ sudo cat /etc/apt/sources.list
deb http://ftp.uk.debian.org/debian/ jessie non-free contrib main   
deb-src http://ftp.uk.debian.org/debian/ jessie non-free contrib main  

deb http://security.debian.org/ jessie/updates main non-free   
deb-src http://security.debian.org/ jessie/updates main non-free 

# jessie-updates, previously known as 'volatile'   
deb http://ftp.uk.debian.org/debian/ jessie-updates main non-free   
deb-src http://ftp.uk.debian.org/debian/ jessie-updates main non-free 

At the end of the lines that begin with “deb” or “deb-src” are the words “non-free contrib main”. As supplied, those lines contain only “main”, which means that the updates will only investigate that Repository. Add the other 2 words.

That change now means that Synaptic can find the manufacturer binaries. The easiest way is to find the error (or ‘fail’) message in the ‘dmesg’ dump, then to search within Synaptic with a snippet of that report. Here is a live example:

(‘dmesg’ only shows the current hardware report, so I'm using ‘kern.log’ to access historic logs)

May 17 13:36:57 ng3 kernel: [    5.823268] ieee80211 phy0: Atheros AR9565 Rev:1 mem=0xffffc90011500000, irq=32

May 17 13:36:57 ng3 kernel: [    5.989716] usbcore: registered new interface driver ath3k

Synaptic first needs the “Reload” button pressing as to update from all the Repositories & find recent changes. Next, searching on “AthrBT_0x31010000.dfu” will land on the “firmware-atheros” package + show that the H30 has the ath3k Bluetooth chipset. Marking that package for install, then applying that command (and rebooting) removes the error + makes the adapter active.

A similar process was needed for (I believe) the Gigabit portion of the Ethernet adaptor:

May 17 13:36:58 ng3 kernel: [   13.861538] r8169 0000:02:00.0: firmware: failed to load rtl_nic/rtl8105e-1.fw (-2)

May 17 13:37:00 ng3 kernel: [   15.647680] r8169 0000:02:00.0 eth0: link up
May 17 13:37:00 ng3 kernel: [   15.647695] IPv6: ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready

The search string “rtl8105e-1.fw” found “firmware-realtek”. Marking & installing that fixed the last of the hardware issues.

Improving the OSM map - why don't we? (13)

Posted by marczoutendijk on 18 May 2016 in English (English)

Improving the OSM map - why don't we? (13)

Why so many people are not using OSM.

Do you recognize the renderer that was used for the above screenshot? I'm pretty sure you can't. Because it wasn't rendered but printed in the Times Comprehensive Atlas of the World.
Looking at this map, it is clear (at least to people who are familiar with "paper" maps [1]) what we see:
* A number of Islands that have a name as a group (Canary Islands) that are part of mainland Spain
* Each Island has its own name (printed in italics or bold italics)
* Each Island has a capital (printed in bold, but this is not true for all the Canary Islands)
* A number of towns is printed in normal type

Now let's see how OSM based maps and renderers show this to the world. The same Islands, with three different ways of rendering (Humanitarian, Mapquest and Mapnik).
The most striking omission (to me) is, that none of the islands is shown with their name and Mapnik shows every Island as "España".
Even when zooming in, the names of the Islands never (and I mean NEVER) show up (I'm supposed to see Tenerife now somewhere on the map):

Now, what kind of a map is that?? Not showing what is most important!?!
Is there a road (top picture) running from Santa Cruz de Tenerife to España?
When I use a (printed) map or atlas, I can see at the large scale maps (1:500.000) what I need to find my way. At that scale I'm not interested if there is a paved/unpaved way ahead of me. And even less I do care about the traffic signs that I might see once I'm there.

I know that everything I'm looking for (and much, much more) is in the OSM database, but why is it shown to me at the wrong moments (if at all) and at the wrong zoom levels?
BTW, Google maps is not doing much better than OSM, showing (some) Island names at high zoom levels.
Do I use OSM myself? Yes!! All the time, and because I have learned to ignore all the crap it is giving me (like showing me the map in Chinese when viewing China, even if English is the language I have installed as my basic language), and because I know the strength it has with the right tools, to me it is the perfect map.
But to a lot of people who are used to a regular printed map or to Google, OSM is just a funny experiment that you can't even use decently on a mobile phone.
Of course, there are tools and apps that use the OSM data in a much more user-friendly way (especially on mobile devices), but why can't openstreetmap.org be a bit more user friendly?

One more example of the incompleteness of OSM.
In the part of the map I'm showing you here, we are supposed to see the capitals of the UK (London), France (Paris), Belgium (Brussels), Luxemburg (Luxemburg) and Holland (Amsterdam). Can you spot them?


Even worse, at this zoomlevel the only capitals shown on the map are London, Dublin and Budapest!!
Madrid, Paris, Brussels, Amsterdam, Luxemburg, Rome, Vienna, Berlin, Oslo, Kopenhagen, Stockholm? What?? Where?? Are they gone??

Friends I'm trying to move over to use OSM (by pointing them to my own openpoimap, I often tell, they call it a "slippy-map", but you better consider it a "shitty-map".

I hope that the developers who are working on the way the basic map is being presented to the users, read this and try to create a map that users recognize instead of being puzzled.
I have said it before, at this moment OSM is a map for mappers, not for users.

[1] Of course there are people who have never seen or used a printed map before, and for those OSM is maybe a great tool, but I doubt it.

Why copying visual style of paper maps is not a good idea

Posted by BushmanK on 18 May 2016 in English (English)

When it comes to visual map styles, there are always some people, who worship paper maps. In case of United States, it's about USGS topo maps, in the UK it's about Ordnance Survey, in case of Russia - about Soviet military topo map (slang name "Genshtab", which means "General Command"). These people always think, that symbology of these maps is something absolutely superior, because professional cartographers were working on it for many years to make it effective. Which is true, but barely relevant to digital cartography.

Here are several reasons why this extrapolation is wrong. (For some people it's an obvious thing, but I just like to have it here in written form to be able to refer to this diary entry in case of discussions and arguments instead of typing it every time I need it.)

Any professionally developed map style is always based on several factors: main use of specific map type, map scale (level of details), media (paper or screen).

Exactly by this reason, there are many different professionally developed standards for civilian topographic maps, hydrographic maps, military maps, aeronautical charts (and they are different, depending on altitude), marine nautical charts. In certain cases, for example - in case of nautical charts - IHO standards are universal (see IHO download page, especially - S-4 document), since it's considered safer to have uniform styles.

Map media played huge role in case of printed maps. It was too expensive and hard to use high-resolution full-color printing before. Low resolution full-color printing is completely unacceptable for maps, since large raster dots distort small objects easily. That's why paper maps were (and still are in some cases) printed with so called "spot colors" - inks of predefined colors (like black, brown, blue, green, orange, red, violet). And that's why paper map styles were developed having this and only this technology in mind. At certain grade, it was true for the first digital maps too, because transflective color LCD screens were far from ideal in color reproduction and their real usable color palette was limited by less than sixteen colors. Everybody who tried to make own styles or maps for those very first Garmin or Magellan GPS devices with color LCD screens should remember that perfectly.

But modern display screen is a high contrast full-color output device, which is at least two times better in terms of contrast than common printed matter. Therefore, it is easy to use more colors and shades for map style without compromising readability. There is no risk of bad color registration (when outlines of different colors are shifted relatively to each other due to bad printing machine setup), so we can use really thin lines, if we want to. Since high quality printing became more available, technical limits of printing process are also way wider now than it was back in fifties, when majority of paper map standards (which are still in use) were initially developed. You can check out Spesifikasjon for skjermkartografi - specification for Norwegian maps, issued by national mapping agency. It's perfect example of more or less full usage of color for different map features, which allows to put more information on map.

Purpose of any map style is the most important factor for its development. It is more obvious for people, when we comparing topographic and nautical charts, but somehow it's not that obvious when it comes to military and hiking maps. Army has own tasks we all know about. That's why Soviet military maps have different symbols for buildings made of wood and stone, because stone houses are fireproof. Same thing goes to roads - they are classified by several factors such as surface and width to give officers an idea, if particular road can be used by tanks and what will happen to it after they pass there. Is it enough for hiker or bicycle rider? Most likely, no. But it's acceptable in case if there is nothing better (like in case of Russia).

To get some idea about maps style, designed for outdoor use by pedestrian, anyone should check out International Specification for Orienteering Maps and some orienteering maps available online. Orienteering maps are perfectly readable, but in the same time, they giving you huge amount of information about landmarks, terrain, vegetation and other things in very dense "package". They even showing features like "wood, passable in one direction" (dense planted forest), "crossable and uncrossable pipelines" and many others. Is there anything like that on maps, intended for tanks? Obviously, no.

Sure, anyone is free to use whatever map one likes and to reproduce its style in MapCSS, SLD or QML, but let's avoid doing it blindly or based on limited knowledge.

São Francisco River, Brazil.

Now the São Francisco River, one of the most important south america rivers, is properly mapped. I had to fix the mess of multipolygons, traced the islands and riverbanks who are left unfinished and put names.

#Flodbanker

Posted by Matss65 on 16 May 2016 in Swedish (Svenska)

Hej alla Opensstreetmap användare. Jag har ett problem med nedre Dalälven som jag lyckats förvränga totalt. Det är runt Marma och Lanforsen i Älvkarleby där jag försökt lägga till lite Öar och rättat till strandlinjen på eftersom jag och många andra vistas i det området. Det verkar dock som jag i detta fallet överskridit min förmåga! :(

Flodbanken har blivit land och dom flesta öar har blivit vatten. Felen syns inte förrän man zoomar och felen ändrar form ju mer man zoomar. Se efter själv Området är indelat i 4 st fjärdar där flodbanken är kopplat via relationer till dom olika fjärdarna. Jag vet dessvärre inte var jag ska leta efter fel, om det tex har med relationerna att göra eller om det är "medlemssskapet" som är ett annat begrepp som jag inte riktigt behärskar.

Är det någon som har nåt tips hur på hur man rättar till det.
