[mapserver-users] OGR VRT and mysql - Unable to identify source...

2009-11-21 Thread aracandrade

Hi,

Sorry about crossposting, I posted this in MapFish users list but I realised 
that here is the correct place. Sorry also my bad english.

I'm learning OGR VRT and mysql, but can't undestand why this error occurs:

my html:

..

var basemap = new OpenLayers.Layer.MapServer("Anhumas",
"http://localhost:8080/cgi-bin/mapserv.exe?";,
{map: 'G:/UsbWebserver/Root/mydata/config/Tremembe/tremembe-mysql.map',
layers: ['lotes', 'reserva', 'labels'],
format: 'png',
transparent: 'off',
maxExtent: new OpenLayers.Bounds(-51.543783, -22.985484, -51.508519, -22.936574)
,mode: 'map'
}, {singleTile: true}
);
map.addLayer(basemap);

map.setCenter(new OpenLayers.LonLat(-51.52669, -22.95777), 13.45);
map.addControl(new OpenLayers.Control.MousePosition());
}
..

my map:

.

LAYER
NAME "lotes"
CONNECTIONTYPE OGR
CONNECTION "G:/UsbWebserver/Root/mydata/config/Tremembe/lotes.ovf"
TYPE polygon
STATUS ON
DATA "lotes"

my ovl:

my orginfo:

Geometry Column = lotcoords

The Firebug answer:


MapServer Message



msDrawMap(): Image handling error. Failed to draw layer named 'lotes'.
msOGRFileOpen(): OGR error. Open failed for OGR connection in layer `lotes'.
Unable to identify source field 'lotcoords' for geometry.



Can anyone please point me where to search for this error? Thanks in advance,

Hi Steve,

The layer is already a global variable. But nevertherless I think I 
found the problem based on your remark. I have used the layer name

of mapserver and not the javascript variable layer reference!


Thanks!!!

Within in my webpage I've some javascript looking like:


The problem is that you need to declare you layer as a global:


var test;


  function init() {


test =  = new OpenLayers.Layer.WMS( ... );


  
info = {
  click: new OpenLayers.Control.WMSGetFeatureInfo({
   'url': 'http://',
   'title': 'Identify features by clicking',


then change the next line to be:
 'layers': [test],


   'layers': "test",


I think that might fix things up for you.

 info.click.activate();
  
  }

   function showInfo(evt) {

highlightLayer.destroyFeatures();
highlightLayer.addFeatures(evt.features);

[mapserver-users] itemfeaturequery & qstring

2009-11-21 Thread Ted Spradley


Hi all,

I apologize in advance for maybe supplying too much detail.  I have
highlighted my questions to try to make this post faster to look through.

I am using mode=itemfeaturequery to locate a polygon by column 'objectid' in
'slayer=parcels', then searching 'qlayer=parcels_01' which is identical to
layer 'parcels' to find all of the parcels within TOLERANCE 500,
TOLERANCEUNITS FEET.

Questions here and then in context:

1: Why doesn't changing the TOLERANCE in layer 'parcels_01' change the
number of parcels returned?
2:  What is the difference between my scenario and the Test Suite?  Besides
attempting to use TOLERANCE > 0?  And the use of FILTER?  And the Test Suite
layer being a shapefile and mine being a spatial DB?  :-)

CGI control 'qstring' appears to pass a string to be used in the WHERE
clause of the SQL query correct?

As always, many, many thanks in advance,
Ted S.


I have encountered two obstacles:

1. My understanding of TOLERANCE and TOLERANCEUNITS - The returned results
are not as expected.  Using units FEET, the returned/mapped records are
identical as long as the value of TOLERANCE is > 0.

Here is the url query:
http://url.com/cgi-bin/mapserv?
qstring=objectid+%3D+1019608  (qstring=objectid = 1019608) ** this is the
subject of 2nd question
&map=/path/to/cad.map
&mode=itemfeaturequery
&slayer=parcels
&qitem=objectid
&qlayer=parcels_01
&qformat=selected_parcel
&mapext=shape

***
To summarize question 1: Why doesn't changing the TOLERANCE in layer
'parcels_01' change the number of parcels returned?

***

2. My understanding of qstring - 

My qstring and related qitem in the above url is:

qstring=objectid+%3D+1019608  (qstring=objectid = 1019608)
&qitem=objectid

My intuition is that it should be 'qstring=1019608' and 'qitem=objectid' -

by looking at the test suit

The problem:
