Simple Google Maps

I tried to use KML to map the Portland Public Schools (PPS), but it seems like there's a definite limit on the number of items you can map this way. When I load the map I get an error: "Parts of http://www.rdrop.com/~moss/... could not be displayed because it is too large."

I don't think the limit is due to file size. I've compressed the KML to a KMZ and that didn't make a difference. Also, I removed a bunch of the data from the description to make the size smaller -- no change. No matter what I do, Google Maps only maps about 70 sites from a KML file. Since there are about 100 PPS schools, this isn't optimal.

By the way: to make a KMZ file from a KML file, just zip it up with WinZip.

So, the comment that Google Maps works better than Yahoo doesn't appear to be entirely true.

In case you're lost...

Yahoo Maps Simple API

Here's a different mapping example. I used Yahoo Maps Simple API.
All you have to do is to put your locations into an XML file and then pass that file to Yahoo via a URL.

This is the same map as the previous -- all the schools in Portland Public Schools.

Here's my second attempt at google maps

I found this site that helps geocode a batch of addresses.
I already compiled a spreadsheet of PPS addresses by school, so I pasted it into the site and that resulted in a bunch of longitudes and latitudes.

Then, the site helped me to map it.
I'll have to spend some time figuring out what it all means.
