- I get the following error opening it in Opera 9 Preview 2: "XML
parsing failed: syntax error (Line: 432, Character: 10)". So look at
your xml again. (id's in XML cannot have spaces: [id="Ichankhu Narayan"]
for example)
- It opens in FF 1.5 but the interaction doesn't work.
- On IE +ASV it works, but the map is probably too heavy. You could
think about showing less layers when you are zoomed out. The more you
zoom in you could add some other layers. I once did this via another
xml-configuration file which looked like this:
<?xml version="1.0" encoding="UTF-8"?>
<mapconfig>
<mapsettings zoomFactor="0.6" panStep="15" maxWidth="1477"
minWidth="50" svgId="svgmap"/>
<zoomranges>
<range id="ZR0" upperBound="1477" lowerBound="500">
<layers>
<BigStreet display="on" showNames="yes"/>
<RegularStreet display="off" showNames="no"/>
<Square display="on" showNames="yes"/>
<UrbanRegion display="on" showNames="yes"/>
<Water display="on" showNames="yes"/>
<Railway display="on" showNames="no"/>
<Parc display="on" showNames="yes"/>
</layers>
</range>
<range id="ZR1" upperBound="500" lowerBound="50">
<layers>
<BigStreet display="on" showNames="yes"/>
<RegularStreet display="on" showNames="yes"/>
<Square display="on" showNames="yes"/>
<UrbanRegion display="on" showNames="yes"/>
<Water display="on" showNames="yes"/>
<Railway display="on" showNames="no"/>
<Parc display="on" showNames="yes"/>
</layers>
</range>
</zoomranges>
</mapconfig>
In each zoomrange I can define which layer I want to see, and which
properties I want show or hide. The upperbound and lowerbound values are
compared with the width of the viewBox to determine in which zoomrange
you currently are. There are probably alternatives for this (and better
ones :)), but this can give you an idea.
- Another more advanced feature which could be useful, especially when
using large maps like yours, is dividing the map into grids, combined
with the changing level of detail I just discussed.
- You should provide some other zoom functions on the client, because
one click on the zoom-in button doesn't really change much. Zooming by
drawing a rectangle for example could be very nice.
- You have created checkboxes to turn the layers on or off on the right
side and the legend on the left side. Why not make an interactive legend
and put the two together. When you have a lot of content inside the
legend, creating a tree would make it possible to close some main legend
categories, making the legend shorter. A scrollbar could also be useful
there.
- You have created pan buttons on the side of the map which are only
shown when the mouse is over them. So the user doesn't know about the
existence of those buttons until he accidently goes over those areas. It
might be better to draw them from the beginning and putting a mouseover
effect on it. Also add some arrows. Many people will associate buttons
with arrows on a map application with panning.
- You can also make your map a lot smaller by using relative map
coördinates for the path elements
(http://www.w3.org/TR/SVG/minimize.html
http://www.w3.org/TR/SVG/paths.html#PathData):
M 24170 17271 L 24246 17251 L 24275 17248 can also be written as:
m24170 17271l76-20l29-3 or m24170 17271 76-20 29-3
When you apply this to your whole map it will be a lot smaller in size.
I believe Andreas Neumann has a tool on his side to create this kind of
paths in an svg-file from a shape-file. Also remove whitespace as much
as you can and, like Ronan Oger said, use gzip.
- Nice work!
