This sample created from the TatukGIS
Internet Server product demonstrates address query and route calculation functionality
with a standard U.S. Census Department TIGER street map and address dataset for Washington
D.C. that has been converted to the SHP file format. The total data set consists of four
map layers totaling approximately 14 MB.
Entering just the first few letters of a street name generally works fine. So typing
in, for example, "Constitution 2101" or "Const 2101" works just as well as entering
the full "Constitution Ave NW 2101".
When entering just a street name with no address number, the query will return the
location of the first segment of the specified street. This is because each
street segment in a raw TIGER dataset is a separate record.
When entering the names of two intersecting streets in one field to specify a location,
use " & " to separate the names. An example would be Penn & Constitution.
The presently available version of the full Internet Server contains advanced address
parsing functionality which is not presently demonstrated in this sample because it is
running on an older IS product version. (The new address parsing functionality – .ParseEx
method - is the same as demonstrated in the DK TigerGeocoding sample in DK download sample
set #6.) One-way street coding is also not activated in this sample.
This sample also demonstrates the implementation of Microsoft Ajax features. Notice how
only the content within the map window, and not the entire browser window, updates after
each map move. This improves the server response time as well the visual comfort for the
on-line user.
