[mapserver-users] addgeometrycolumn function not identified!!!
Hi,
I am trying to convert my shape files to postgre files. After getting sql
file, postgre got struck by not recognising addgeometrycolumn function.In
one of my files--
SELECT AddGeometryColumn('','gisdb','the_geom','-1','MULTILINESTRING',2);
works while in other
SELECT AddGeometryColumn('','gisdb','the_geom','-1','MULTIPOLYGON',2);
doesnt work.
Also I m unable to find lat long from successfully generated file.
Please help me out urgently.
Regards
Mukul.

RE: [mapserver-users] Get the nearest layer with mapscript...
Probably dont understand what exactly you are trying to achieve here but it is not as simple as map.getLayer(0) to get the topmost layer? And once you have the layer object use one of the query function to select the record? E.g. myLayerObj.queryByPoint ?

[mapserver-users] Limit of records
Hi, I have problems with some layers and I'm thinking that the reason is the number of records. For example, with a layer which has 63057 records, the result is the following: 500 Internal Server Error And Apache log error: Timeout waiting for output from CGI script /var/cgi-bin/mapserv If exist a limit, which is the maximun number of records that mapserver can support?

Re: [mapserver-users] Limit of records
Hi, There is no limit for number of records in Mapserver. Apache. that is used as http server in front of Mapserver does have timeout, which is 300 seconds by default but can be adjusted. Generally speaking number of records does not tell much about how hard that layer is to handle, if anything. It depends more on the vector data format, nature of the features (points vs. polygons with thousands of vertices), indexing etc. However, I would say that normally 63 thousand features is not much and if Mapserver hits the timeout then the data are not suitable for Mapserver without some preprocessing. So, please describe what kind of data you have. Ogrinfo report about the layer would be a good addition. -Jukka Rahkonen- Lähettäjä: mapserver-users-boun...@lists.osgeo.org [mailto:mapserver-users-boun...@lists.osgeo.org] Puolesta Iratxe Lejarreta Lähetetty: 20. toukokuuta 2009 13:40 Vastaanottaja: mapserver-users@lists.osgeo.org Aihe: [mapserver-users] Limit of records Hi, I have problems with some layers and I'm thinking that the reason is the number of records.

Re: [mapserver-users] Limit of records
Hi Iratxe, I've found that the limit on my maps is 2000 records. I store the points in a MySQL database and use PHP/MapScript to create the map so I don't know what sets this limit but 2000 points on a map seems fair enought for the average map. Unless you have a very big map it would quickly get too cluttered and difficult to read for the users.

Re: [mapserver-users] Limit of records
Hi, I made a quick test by commenting out my MAXSCALEDENOM and MAXFEATURES settings. For me it takes now around 10 seconds to draw 1.1 million polygons from Oracle spatial through WMS. Timing comes from Mapserver log with layer set to DEBUG 5. Sure it does not make sense to draw 1.1 million polygons to 500x400 pixels on screen but it does not need to be extraordinary slow either. -Jukka- -Alkuperäinen viesti- Lähettäjä: mapserver-users-boun...@lists.osgeo.org [mailto:mapserver-users-boun...@lists.osgeo.org] Puolesta Peter Rose Lähetetty: 20. toukokuuta 2009 14:21 Vastaanottaja: mapserver-users@lists.osgeo.org Aihe: Re: [mapserver-users] Limit of records Hi Iratxe, I've found that the limit on my maps is 2000 records.

If you only need to create your map as a static image (with no pan and zoom), you could use MapServer to generate a html imagemap. See the documentation here: http://mapserver.org/output/imagemaps.html Most people these days are using openlayers http://www.openlayers.org or another javascript library to do this. A lot of people are using OpenLayers to build their map interfaces, I recommend that you check it out.

Re: [mapserver-users] Get the nearest layer with mapscript...
If you're doing point queries MapServer/MapScript can do this for you. You do a mapObj.queryByPoint with the MS_SINGLE mode and then the function will identify the closest feature (considering TOLERANCEs!) in the top-most ACTIVE layer. This site uses this to it's advantage... http://www.dnr.state.mn.us/maps/compass.html A query drops through the layers until a match is hit. Even with other geometry types based on what was described you can probably do it pretty easily. You'd use one of the other query methods and then once the query is done loop through your layer stack backwards (e.g. starting at the top) and stop when you find one with results.

[mapserver-users] Open3DGIS
Hi all, I am investigating different options on using 3D with MapServer.. There was once an application called Open3DGIS (http://open3dgis.sourceforge.net/), which doesn't seem to live anymore. Are there any other tools / addons that are alive in this field? Thanks! Matej ___ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users
Re: [mapserver-users] Open3DGIS
Hi Matej, Take a look at osgEarth (http://osgearth.org), a toolkit that renders open-standards data (from WMS, MapServer, TileCache, etc.) in 3D using the open source OpenSceneGraph library.

Hi Steve!
I didn't know that mapObj could call queryByPoint as well ... Thanks...
But, How can I get the feature selected after query ?
Using LayerObj I did that (using layer.getNumResults() )
if (_layer.queryByPoint(MapaObj, _point, 0, -2) == 0)
{
for (int i = 0; i _layer.getNumResults(); i++)
{
resultCacheMemberObj _result = _layer.getResult(i);
return _result.shapeindex.ToString();
}
}
How can I do that using MapObj ?

Very strange. I don't see an xml file but now I've tried this and I do
get an instance of an imageObj back:
my $map = new mapscript::mapObj('test.map') or die no map $!;
$map-saveMapContext('test.xml');
my $image = $map-draw();

So I guess I'll proceed and see how things go. Thanks for your input.

What does your code look like? The following works for me:

my $name = $map-get(name);

Any thoughts?

Re: [mapserver-users] GRIB files - gdal_translate
Hi there! There is nothing wrong with your block X and Y size (161x1). It indicates that your data is not tiled/blocked, so it is most likely to be read row by row. If the image looks strange is not because of that. You have 98 rows in 0.02 degrees, so if it looks like a line, I wouldn't be suprised. Have you try to open it in another GDAL based client application, like QGIS for example?

The issue is that, when mapserver renders this layer it only draws a straight line below South America, exactly where the whole image should start, as my CTL below shows. dset ^T126L28.grb title pac/sa/atlan sector: troposphere file undef 1e+20 dtype grib index ^T126L28.gmp xdef 161 linear -150.15 0.937500 ydef 98 levels -61.246 -60.311 -59.376 -58.441 -57.506 -56.571 -55.636 -54.701 -53.766 -52.831 -51.896 -50.961 -50.026 -49.091 -48.156 -47.221 -46.286 -45.350 -44.415 -43.480 -42.545 -41.610 -40.675 -39.740 -38.805 -37.870 -36.935 -36.000 -35.065 -34.130 -33.195 -32.260 -31.325 -30.389 -29.454 -28.519 -27.584 -26.649 -25.714 -24.779 -23.844 -22.909 -21.974 -21.039 -20.104 -19.169 -18.234 -17.299 -16.364 -15.429 -14.493 -13.558 -12.623 -11.688 -10.753 -9.818 -8.883 -7.948 -7.013 -6.078 -5.143 -4.208 -3.273 -2.338 -1.403 -0.468 0.468 1.403 2.338 3.273 4.208 5.143 6.078 7.013 7.948 8.883 9.818 10.753 11.688 12.623 13.558 14.493 15.429 16.364 17.299 18.234 19.169 20.104 21.039 21.974 22.909 23.844 24.779 25.714 26.649 27.584 28.519 29.454 zdef 7 levels 1000 925 850 700 500 300 200 === set Z 1 ou 2 ou 3 ... ou 7 (GRADS) tdef 1 linear 6Z16may2009 6hr vars 15 psnm 02,102, 0, 0 SEA LEVEL PRESSURE [hPa] tsfc 0 187, 1, 0, 0 SURFACE TEMPERATURE [K] prec 0 61, 1, 0, 0 TOTAL PRECIPITATION [Kg/m2/day] cbnv 0 71, 3, 0, 0 CLOUD COVER [0-1] role 0 114, 8, 0, 0 OUTGOING LONG WAVE AT TOP [W/m2] mask 7 137,100 MASK [-/+] uvel 7 33,100 ZONAL WIND (U) [m/s] vvel 7 34,100 MERIDIONAL WIND (V) [m/s] omeg 7 39,100 OMEGA [Pa/s] fcor 7 35,100 STREAM FUNCTION [m2/s] potv 7 36,100 VELOCITY POTENTIAL [m2/s] zgeo 77,100 GEOPOTENTIAL HEIGHT [gpm] temp 7 11,100 ABSOLUTE TEMPERATURE [K] umrl 7 52,100 RELATIVE HUMIDITY [no Dim] umes 7 51,100 SPECIFIC HUMIDITY [kg/kg] endvars Can someone help me to find out what is happening?

Roberto, In MapServer you always classify rasters based on the item [pixel] but you do not need to explicitly state a classitem. This is a relatively simple example of raster classification. LAYER NAME grid1 TYPE raster STATUS default DATA data/float.tif CLASS NAME red EXPRESSION ([pixel] -3) COLOR 255 0 0 END CLASS NAME green EXPRESSION ([pixel] = -3 and [pixel] 3) COLOR 0 255 0 END CLASS NAME blue EXPRESSION ([pixel] = 3) COLOR 0 0 255 END END I can see my grib using Grads but what tool do I use to translate individual bands into GeoTIFF? You can use gdal_translate to extract particular bands from a grib file as a geotiff (or all the bands). For instance, the following would extract band 3 (total precipitation): gdal_translate -b 3 T126L28.grb total_precip.tif Converting the data on-the-fly to an image is the right way to work? Having MapServer access the grib file on the fly rather than
Re: [mapserver-users] Finding Lat-Long from geometric data type of postgre
Hi, I use a combination of server code and Javascript. I convert the lat long values to a javascript array which is loaded into a 2 dimensional array. This data is then loaded with the map which is quick if your polygons are not too complicated. I then have a mouse over ont he map which checks as the mouse moves to see if is within the polygon. Since I am already creating lat/long values from the mouse over I just need to do a simple point in polygon check and I am there. The other way I have thought is to create a html map using the polygon values that come back but I haven't done that. To display the tooltip I use js_graphics (http://www.walterzorn.com/) library of tools which I find fantastic.

Re: [mapserver-users] Precache
Your request is somewhat lacking in detail, but assuming that your goal is a simple one, here is one way to accomplish this. 1. Create a MapServer project that displays your shapefile in whatever style you choose. 2. Setup a TileCache instance that points to your MapServer project. 3. Run the tilecache_seed.py script to pre-generate tiles. Roger -- On Wed, May 20, 2009 at 12:16 PM, Chad Clabaugh cclaba...@centwire.com wrote: How can I precache tile images from shapefiles?
