Map applications & services |
- OpenStreetMap - an
open-source project that
‘creates and provides free geographic data such as street maps
to anyone who wants them’. The Web sites are rather confusing
because there are a number of related projects, a number of ways
of accessing the maps, a number of different map renderings, and
a number of ways to edit and export the maps, and the relationships
of all these bits are not always well explained for newcomers.
- The home page provides access to the map for
viewing, editing and exporting, and permits uploading
and management of GPS traces.
- OpenStreetMap wiki
provides documentation, including a discussion of the various
contact channels for help and discussion.
The newbies e-mail list
(a general users' help list) was terminated in 2016 Jan
in favour of
explains how to use OSM to put maps on Web sites,
‘from first principles to technical how-tos’.
- OSM Inspector
‘created as a more or less general tool to show different views of OSM data
in order to help advanced OSM users debug the data.’
Among other things, it provides access to detailed histories of individual
nodes and ways.
The Information Freeway offers a number of alternative
base layers and an optional Maplint overlay;
I haven't found any documentation and it's not clear
what the different layers do.
At zoom = 6 and 12, individual tiles are outlined;
it used to support the typing of
'r' to render and 'i' for status information but these
no longer work since Tiles@Home was decommissioned.
- Printing maps
- Field Papers
(a continuation of Walking Papers)
renders city maps on demand, for printing on
large paper or in sets of regular-size paper,
with street indexes.
(One sequence for printing: use PDFSAM to remove p. 2
(which is intentionally blank) so the maps themselves
start on an odd-numbered page, and then print selected pages
two-up and two-sided-short-edge)
- and others
- Stephan Bösch-Plepelits’
‘is an application to 'browse' through the information in
the displayed part of the map. The aim of the project is
to provide a highly dynamic map that makes every mapped feature
easily available to the user.’
As of 2018 Aug there is a very nice rendition of public transit.
OpenCycleMap is based on OSM; it also uses
NASA's SRTM topographic data for height contours
OpenPisteMap, also based on OSM, shows a map of
skiing and snowboarding pistes.
displays a grid showing how many open-licensed street-level photos
it has found on the Web for each grid square,
and includes a photo viewer.
- One can also create customized maps and embed them in a Web site

post about extracting data from OSM using

layers by custom tiles.
‘is a format for encoding a variety of
geographic data structures’.
GeoJSINLint is a site
for validating GeoJSON data - the data are interpreted and
displayed on a map, and errors are reported.
- Maperitive is a
zero-cost (not open-source) desktop application that
loads map data and permits the user to modify the rendering
rules and export the results as bitmap or SVG files.
- OpenLayers is
in most modern web browsers,
with no server-side dependencies’,
used for displaying OSM maps.
See, for example,
Using Custom Tile Sources and
documentation of the OpenLayers object.

discussion of alternatives,
especially for non-mapping applications.

resulting from OSM's change to a
- Natural Earth
provides public-domain map data with tightly integrated vector
and raster data at 1:10M, 1:50M AND 1:110M scales.

LOCOSYS Genie GT-31/BGT-31 is a neat handheld GPS device.
OpenStreetMap had a
special deal with the UK distributor whereby
10% of the price was donated to the project;
the Canadian distributor was

is an open-source programme to visualize and analyze tours
which are recorded by
a GPS device, a bike or exercise computer, or an ergometer.
Among many other features, it displays the tours (tracks) over
maps from a number of different sources, and can display
speed, altitude and
gradient profiles against either time or distance.

- Snippets: In the displayed list of ,
for each item there may be displayed one or two lines of text, which
represents either the beginning of the
the item, if any, or text defined in a
Snippet XML element
myplaces.kml. It doesn't seem to be possible to
suppress the display of this text using the GUI. To suppress it, edit
with a text editor:
(1) If the text is defined explicitly in a
element and there is no text in a
(2) If there is some text in a

I thought that it might also be possible to suppress the text
display globally by changing the default
