[OpenLayers-Users] Accessing tile structure generated by ArcGIS 9.3

Tue Feb 17 03:45:07 EST 2009

Hi!

I am trying to access the tilestructure generated by the ArcGIS Server 9.3.

I found the AGS.js on the website, it is to manage the AGS layers but the
fact is that it works only for the first 4 levels of tiling. Deeper than the
fourth level, if more than one AGS layer is added to the map, those layers
do not overlap anymore. 

Also, they do not coincide with the basemap (in my case a TileCache layer)
that surely works.  You can check this behavior at
http://dma.jrc.it/testmap/

The layers definition is the following:

var AGSlayer = new
OpenLayers.Layer.AGS("AGS","http://139.191.1.149/arcgiscache/DMAEurope_merc/
Layers",{layername:'_alllayers', type: 'png', format:
'image/png',isBaseLayer: false,

             transitionEffect: 'resize', wrapDateLine: true, tileOrigin: new
OpenLayers.LonLat(-22041259.177067, 22041259.177067)});//-60112524.6784,
30056262.848000005)});

             var AGSlayer2 = new
OpenLayers.Layer.AGS("AGS2","http://139.191.1.149/arcgiscache/global_test_1/
Layers",{layername:'_alllayers', type: 'png', format:
'image/png',isBaseLayer: false,

             transitionEffect: 'resize', wrapDateLine: true, tileOrigin: new
OpenLayers.LonLat( -22041257.773878, 20855374.584800)});

I have checked the two tile image folder and the images with the same row
and column indexes are exactly the same. I think it is the OL that somehow
positions the images badly.

Anybody with a similar experience?

Many thanks 

S.

Subject: [OpenLayers-Users] WFS ProxyHost

Hi!

I'm having some troubles on trying to use WFS...

As suggested in the FAQ, and put the proxy.cgi on cgi-bin Apache folder, and
add the line "AddHandler python-cgi-script .cgi" on httpd.conf, as suggested
in http://gist.fas.harvard.edu/chgis/?p=14.

But loading the following page, I receive the error 1012, on Firebug.

Help please!!!
