<font face="Arial">I am unable to get the InstallImagePlugin to work
in JOSM<br>
<br>
GOAL<br>
====<br>
<br>
I have an image of a map that I scanned and I want to load it into
JOSM as an underlay so I can trace the ways on the map in JOSM.<br>
<br>
PREPARATION<br>
============<br>
<br>
The map file is called map.jpg and I have created a world file
called map.wld<br>
<br>
TRIALS<br>
======<br>
<br>
I don't fully understand the values I need for the world file,
however it represents an area approximately 8 kilometres (West to
East) by 6 kilometres (North to South) and the top left hand edge
of the map is approximately at a latitude of 1.5 (North) and a
longitude of 103.5 (East) so I looked at this link:
<a class="moz-txt-link-freetext" href="http://en.wikipedia.org/wiki/World_file">http://en.wikipedia.org/wiki/World_file</a> and my file contains these
values as a starting point:<br>
<br>
100.0<br>
0.0<br>
0.0<br>
-100.0<br>
103.5<br>
1.5<br>
<br>
When I load the image, the plugin notices that I don't have a
projection file (.prj) so it asks me if I want the default
coordinate system. I choose Yes. Nothing appears and the scale
(top left corner of JOSM goes to 20037.5 and I cannot zoom in or
out. I have varied the values in the world file considerably but
with the same result.<br>
<br>
QUESTIONS<br>
==========<br>
<br>
Has anyone used this plugin?<br>
Can you give me reasonably correct values for my world file?<br>
Do I need to create a projection file<br>
What do I need to do to make this work?<br>
<br>
Thank you,<br>
<br>
