Re: Question about why my point data shapefile does not display

Hi Brian,

Points are supported in the ShapeLayer. I just tried this out with an
airport file, and the dots came up on my map.

In the properties file, you can also define a property:

bridges.pointImageURL=<URL to image file>

That will put the image (icon) over every spot.

I'm not sure why the points wouldn't be showing up for you. The
properties look OK. I can test out your file if you want to send it to
me.

That's nice to hear.
