[Mapserver-users] Multiple counties in a template file !!!

Fri Apr 2 00:34:28 EST 2004

Tyler
Thanks for that . Yes steve pls advise me on usage of tileindex etc . But a 
correction tyler ...
I am no longer using tiger file directly ( OGR connection as u showed me ) 
but instead I have downloaded the TIGER Line 2000 files in *shape* file 
format from
http://arcdata.esri.com/data/tiger2000/tiger_download.cfm
http://www.esri.com/data/download/census2000_tigerline/index.html
and have at me hands the following layers for NH -rockingham county ...
Line Features - Roads lkA
Line Features - Rails lkB
Line Features - Misc. Transport lkC
Line Features - Landmarks lkD
Line Features – Physical lkE
Line Features – Non-visible lkF
Line Features – Hydrography lkH
Line Features – Unknown lkX
County 2000  cty00
Designated Places 2000 plc00
Key Geographic Locations kgl
Landmark Polygons lpy
Landmark Points lpt
Water Polygons wat
Landmark Polygon Names lpy2

The status with these layers are ..I am able to display line features like 
roads , rails but not hydrography ( dont know why but have attached my MAP 
file below for ur reference )
I am able to display all polygons - water , landmarks .but still labels are 
missing . I am yet to implement the ideas given my tyler in another reply .
NOT AT ALL ABLE TO DISPLAY THE POINTS - key geograpic locations , designated 
places , etc.
So this my status and I will update soon after my progress . My ultimate aim 
is to have an app that will render the choosen states ..and then on the 
states users click on to zoom into layers of counties ...etc and also with 
LOCATION QUERY feature to locate and zoom in to the area entered by the user 
. I am working on this also as tyler gave me some more links ...
