Google Maps : Java Glossary
Google Earth shows you aerial photographs and street level
photographs to let you virtually explore a city. Google Maps displays
conventional maps. It also works out optimal routes for car, cyclist,
pedestrian and bus rider. It even shows flights.
- It find routes and alternate routes instantaneously.
- It will show you a picture of your destination, so you can find it
even if it has no street number.
- It is free.
- It will show you a street level picture of your destination. This
makes the final homing in easier especially when none of the
businesses or homes post their adress numbers.
- Maps printed on a printer are not nearly as clear as those you buy
at a gas station.
- Maps have most of the small streets left out.
- Street names are obscured by the suggested route lines.
- When you print, it is hard to center the map on the area of
- The maps are small. If you get lost and wander off the edge, you
- Many streets lack signs and most businesses lack street numbers.
This is not Google’s fault. In contrast,
GPS (Global Positioning System)
can work with unlabelled streets and houses.
- If you get lost, Google printed maps are all but useless. They
have no street numbers. They don’t have the minor streets. I
asked half a dozen people to point out where I was on a Google map.
None could do it. There were not enough labelled streets. There were

- Homing in on a spot on the map on the computer screen is far more
awkward than it needs to be. When you zoom, the spot you want
disappears off screen. You should be able to point at the spot you
want and as you slowly zoom, keep it centred by pointing ever more
accurately. They should have a look at how some hand held
units handle the problem even with a much smaller screen with

from Google. They will give you a key.

Google Maps have the following problems when printed:
- The type is too small to read any of the street names.
- Most of the streets are left out.
- There are no block or house number.
I have written Google twice asing them to fix this. So far no reply.
Here are my suggestions to fix the problem:
- Use large type that spills out of the street margins.
- When Google prints a map, it should take as many pages as
needed to make it legible, printing bits that when stitched together
form the route.
- It should print numbers on the streets and print a legend on the
back of the map for which street each number signifies.
