Google Cartography
Please wait a few seconds for the applet to load. For best results you should read the instructions below before proceeding.
When the applet starts you will be prompted for some parameters. The parameters are described in detail in the following table.
| Parameter | Description |
|---|---|
| Google API Key | Your Google API key. If you don't have one already you can register for one at the Google API page. |
| Maximum Key Used | This is the maximum amount of Google API key juice the applet will use. |
| Maximum Results Per Street | This is the maximum number of results the applet will process per street. The total number of streets explicitly searched for can be estimated using the formula: ((Maximum Key Used) * 10)/(Maximum results per street). You'll get some streets for free when processing other streets' results - and some streets may return less than the maximum results per street - so it's just an estimate. Increasing the maximum results per street will increase the density of the graph (i.e. the number of edges per vertex[intersections per street]); decreasing this number will increase the spread of the graph (i.e. how far from the starting street the graph will reach). |
| Starting Street |
The street which will form the hub of intersections of the current graph. Use the full name i.e 'park avenue' rather than 'park'. Don't use abbreviations such as St or Rd. You should also NOT place the street name in quotes. Note that a successful result depends on how much data exists on the web for this street. For example '8th avenue' is likely to produce good results. 'Little Red Wagon Street' (a small street in an outer 'burb in Hicksville) is unlikely to have enough data to produce a graph. Usually anything outside the inner city region of a major urban centre doesn't have sufficient data to produce decent results.
|
| Other Narrowing Criteria | To avoid including streets completely unrelated to the starting street, it helps to add extra search criteria. For example, if you entered "oxford street" for the starting street and you have Oxford Street London UK in mind then try entering 'site:.uk london' here. Getting too narrow decreases the quantity of results; going too broad will decrease the quality of results. Quotes here are often useful, so use "new york" instead of new york where possible. |
