This sample demonstrates the use of the TatukGIS
Internet Server LITE edition to internet publish vector road and street map data,
along with map layers containing other information of interest. The data set, composed of layers in
SHP file format, totals approximately 260 MB, yet each screen view refreshes quickly over a fast internet
connection. (If the data set had been very much larger – 2 GB or more – it would have made sense to convert
the vector map layers into SQL database files for faster presentation at closer zoom levels.)
The TatukGIS IS software correctly presents Polish language characters over the Internet,
regardless of the type of browser or other software running on the client user station.
East European 852 code page in the original data set is converted "on the fly" into
Unicode and then displayed using the E. European 238 character set. The TatukGIS IS
similarly supports the display of any character type, e.g., Russian, Chinese, Arabic,
Japanese, etc. Also note how the TatukGIS software automatically rotates the names
of rivers or streets to best follow the portion of the river that is visible in any
given view and how the names of rivers and numbers of roads automatically repositioned
as the user scrolls across the map so that the relevant information is displayed in
every view.
This sample also demonstrates the PDF document generation feature, which allows the
on-line user to create a PDF file from any selected map view.
This sample also demonstrates:
-
the Flash control, which can be turned on/off by each on-line user, and
-
PDF document generation, which allows the on-line user to create a PDF file from any selected map view.
The map layers in this sample containing the road, street, rail, and ferry line data are provided by the company AND
Automotive Navigation Data (www.and.com). AND,
based on the Netherlands, is a leading supplier of vector map navigation data (addresses,
roads, and routes) for all regions of the world.
The other map layers – showing rivers, lakes, forested areas, etc. – are less precise than the AND map data
and sometimes do not match perfectly at close zoom levels.
