This sample created with 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.
Enter any valid street name, the name of two intersecting streets, or a valid street name
and address number in the upper field to query for the map location. Enter any starting
point and any termination point - each defined by a street name, names of two intersecting
streets, or a valid street name and address number - to generate the shortest street route
between the two locations.
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.
One-way street coding is also not activated in this sample.
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 supports advanced address
parsing functionality which is not yet demonstrated in this sample, because this sample
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.)
