Re: pyramid, .rrd file

Frank Warmerdam — 2008-12-01T19:04:40

Attila, Generally speaking Mapserver should already take advantage of .rrd pre-built overviews. If you want to confirm if GDAL (and consequently MapServer) can see the overviews, run the gdalinfo utility on the base file, and check the report of the individual bands to see if they have an overviews list. For example gdalinfo image_col.img ... Band 1 Block=64x64 Type=UInt16, ColorInterp=Undefined Description = Layer_1 Min=232.000 Max=1024.000 Minimum=232.000, Maximum=1024.000, Mean=335.990, StdDev=26.558 NoData Value=65535 Overviews: 692x600, 345x299, 171x148, 84x73, 41x35 ... This file has an .rrd ith 5 overview levels and they would be used by MapServer as long as the .rrd file is kept with the .img file. Best regards,

That should fix it. The problem is that MapServer strings must start with a alpha character. Otherwise they must be quoted.

Re: LINE layer on small scales

Jochen Topf — 2008-12-01T11:50:04

GROUPed layers are a bit different from normal layers. For instance it seems I can't set keywords for grouped layers (No OWS_GROUP_KEYWORDLIST), which is something I need for my application. I could probably change my app to also work with nested layers but that looks like a lot of work. :-) Jochen

LINE layer on small scales

Jochen Topf — 2008-12-01T10:15:21

Hi! I have bunch of linestrings I want to show in one layer. Each linestring should show up as a line on large scales and as a symbol on small scales, because on the small scales the lines are too short to see. I know how to do this with two layers: One LINE layer and one POINT layer with the same underlying data. But I'd rather do this in one layer and use different CLASSes for the different scales. But when I do this the symbols keep disappearing on smaller scales, I guess because the linestrings get so short that Mapserver decides to not draw them at all. Can this be done? Any ideas? Jochen

Re: grayscale images using classgroups

Martin Kofahl — 2008-12-01T05:26:32

I found a formula RGB2grayscale = 0.299R + 0.587G + 0.114B and would like to apply this on a class section in order to use the STYLE-parameter for serving a raster layer colored or generic grayscaled. Due to processing instructions work on layer level only, they do not help in this case. I'm looking for a solution like this: CLASS CLASSGROUP 'grayscale' STYLE COLOR [grayscale] [grayscale] [grayscale] END END CLASS CLASSGROUP 'color' STYLE COLOR [red] [green] [blue] END END -------- Original-Nachricht -------- _______________________________________________ mapserver-users mailing list mapserver-users< at >lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users

RE: Preparing/modifying a querymap forfurtherzoom/pan operations...

2008-11-28T04:20:45

Hello Nick. I was stumped by the same thing for a time. I solved it by running the query twice. It feels kludgy, but it works--I'll clean it up later. The first time through is an itemnquery, which does an AJAX call to a template. That returns a set of JSON variables from the template (all I need are the new map extents). These are then stored in the mapserve object extents, following which I rebuild the query as an itemnquerymap. This produces the map of the same query with the qstring items highlighted. I can then pan, zoom, etc. from there. Here's the code I used in the main file. Much of it is shamelessly stolen from better coders than I. The JSON setup in the template is pretty straightforward. I've put it below the javascript. Note that the routines that build the URLs use different mapfiles. One is tailored just for JSON, while the other handles regular queries. --Jim Haug // javascript code to do itemnsearch and itemnsearchmap. // we will be doing searches using ajax/json to provide data. function item_search(), // which is called from form 'searchform' in the document, // will set up an itemquery url to send to the server. It will then call // function getData(url), which will make an ajax call using the itemquery url. // Data will be returned from the template in json format, which will allow // function onResponse() to parse it to variables. function item_search() { var query_url = ""; var layerlist = ms.getLayers('+'); if (document.searchform.qitem.value == "site_no") { qitem = "site_no"; qlayer = "sites"; } else if (document.searchform.qitem.value == "archive") { qitem = "archive"; qlayer = "surveys"; } else if (document.searchform.qitem.value == "histdist") { qitem = "reg"; qlayer = "hist-dist"; } else if (document.searchform.qitem.value == "histdistr") { qitem = "reg"; qlayer = "hist-dist-restrict"; } else if (document.searchform.qitem.value == "bridges") { qitem = "propertyna"; qlayer = "bridges"; } else if (document.searchform.qitem.value == "cemeteries") { qitem = "propertyna"; qlayer = "cemeteries"; } else if (document.searchform.qitem.value == "structures") { qitem = "propertyna"; qlayer = "structures"; } else { // must be trs, since it's the last choice in the form qitem = "arms_plss"; qlayer = "sd_plss"; } qstring = "/" + document.searchform.qstring.value + "/i"; query_url = ms.mapserver + '?mode=itemnquery' + '&map=' + query_mapfile + '&qlayer=' + qlayer + '&qitem=' + qitem + '&qstring=' + qstring + '&mapext=shapes' + '&mapsize=' + ms.width + '+' + ms.height + '&layers=' + layerlist + ms.options; getData(query_url); } // this.setLayer = function(name, status) { // self.layers[name] = status; // } //--------------> start of itemquery search functions using ajax/json var myrequest; function getData(url) { myrequest=null; if (window.XMLHttpRequest) { // code for IE7, Firefox, Mozilla, etc. myrequest=new XMLHttpRequest(); } else if (window.ActiveXObject) { // code for IE5, IE6 myrequest=new ActiveXObject("Microsoft.XMLHTTP"); } if (myrequest!=null) { myrequest.onreadystatechange=onResponse; myrequest.open("GET",url,true); myrequest.send(null); } else { alert("Your browser does not support XMLHTTP.\nYou need to upgrade"); } } function onResponse() { if(myrequest.readyState!=4) return; if(myrequest.status!=200) { alert("Problem retrieving data"); return; } if (myrequest.responseText.indexOf("msQuery") != -1) { alert("No item found in search"); } else { // parse the returned query data var my_ms = eval('(' + myrequest.responseText + ')'); // all we really need are the extents (minx and y, max x and y) in order // to set up a new map to be drawn // make sure the page is ready to display a map ms.mode = "map"; // buffer the coordinates by 1000 map units (set to meters in map file) minx = parseFloat(my_ms.minx) - 1000; miny = parseFloat(my_ms.miny) - 1000; maxx = parseFloat(my_ms.maxx) + 1000; maxy = parseFloat(my_ms.maxy) + 1000; ms.setExtent(minx, miny, maxx, maxy); var layerlist = ms.getLayers('+'); if (document.searchform.qitem.value == "site_no") { qitem = "site_no"; qlayer = "sites"; } else if (document.searchform.qitem.value == "archive") { qitem = "archive"; qlayer = "surveys"; } else if (document.searchform.qitem.value == "histdist") { qitem = "reg"; qlayer = "hist-dist"; } else if (document.searchform.qitem.value == "histdistr") { qitem = "reg"; qlayer = "hist-dist-restrict"; } else if (document.searchform.qitem.value == "bridges") { qitem = "propertyna"; qlayer = "bridges"; } else if (document.searchform.qitem.value == "cemeteries") { qitem = "propertyna"; qlayer = "cemeteries"; } else if (document.searchform.qitem.value == "structures") { qitem = "propertyna"; qlayer = "structures"; } else { // must be trs, since it's the last choice in the form qitem = "arms_plss"; qlayer = "sd_plss"; } qstring = "/" + document.searchform.qstring.value + "/i"; if(ms.referencemap) { ms.referencemap.url = ms.mapserver + '?mode=reference' + '&map=' + ms.referencemap.mapfile + '&mapext=' + ms.extent.join('+') + '&mapsize=' + ms.width + '+' + ms.height; } ms.url = ms.mapserver + '?mode=itemnquerymap' + '&map=' + query_mapfile + '&qlayer=' + qlayer + '&qitem=' + qitem + '&qstring=' + qstring + '&mapext=' + ms.extent.join('+') + '&mapsize=' + ms.width + '+' + ms.height + '&layers=' + layerlist + ms.options; ms_draw(); } } //--------> end of itemquery search functions ========================================= JSON code from queryfooter.html { "minx": "[minx]", "miny": "[miny]", "maxx": "[maxx]", "maxy": "[maxy]", } -----Original Message----- From: mapserver-users-bounces< at >lists.osgeo.org on behalf of nikos< at >maich.gr Sent: Thu 11/27/2008 3:22 PM To: mapserver-users< at >lists.osgeo.org Subject: [mapserver-users] Preparing/modifying a querymap for furtherzoom/pan operations...
