Thanks Ed & Chip,

I tried to set the layer to type point and the problem=20
persists.

When I try to use the 'drawLabelCache()' method I get the following error
at the line of the php/mapscript file making the method call - 

Fatal error: MapServer Error in msGetBitmapFont():
Invalid bitmap font.

Must be one of tiny, small, medium, large or giant. 

Currently I have the annotation layer as the last layer entry in the map
file - and it is still being drawn over by the other layers.  Could
it be how I am defining my other layers?  Here is an
example:

LAYER

  NAME 'states'

  TYPE POLYGON

  STATUS ON

  DATA 'north_america/usa/statesp020'

  MAXSCALE 26000000

  MINSCALE 1

  GROUP 'north_america'

  CLASS

    NAME 'states'

    OUTLINECOLOR 204 204 204

    COLOR 255 255 204

    LABEL

     COLOR 0 0 0

        SIZE
SMALL

    END

  END

END

Am I possibly running into a v3.5 issue?

Dan,

try using 'drawLabelCache' from MapScript right before you render your

image:

  $img =3D $map->draw();

  $map->drawLabelCache($img);

  $url =3D $img->saveWebImage(MS_PNG, $map->transparent,

Dan -

That seems very odd.  Can you try making the layer TYPE POINT and
see if

that changes anything (just a stab in the dark)?

Ed,

Thanks for the reply.  I have and had tried moving the layer
definition to

the beginning and the end of the map file with the same results.  I
had

figured it to be more php/mapscript related issue, though when I draw
the

layer last in php/mapscript I also have the same result - the
annotation

layer is drawn under the other layers.  Any other ideas?

Thanks,

Dan

Subject: [Mapserver-users] How to Draw Annotation Layer Last

Hello,

I have searched through the archives w/o much luck on determining what I
am

doing wrong.  

I am using MapServer v3.5 and am trying to draw an annotation layer so it
is

always the last layer to be drawn and shows on top of all other
layers.

Right now it is always drawn under my other layers and is not seen. 
I also

use PHP/Mapscript to create the maps and have tried to force this layer
to

be drawn last, w/o success.  Can anyone clue me in on the method to
ensure

this layer is always draw last, either via the map file only or via

php/mapscript?  Below is the map file entry for the layer and
the

php/mapscript snippet.

Thanks!

The distancetoshape calculates the MINIMUM distance between a point and a
shape. So the closest point on the shape will be used to do the distance
calculation.

List,
Sorry for the off-topic, but I've looked everywhere trying not to bother
the group.

I've discovered Fred Pierssen's EDTOOLS script and have used it to
extract intersections from a road theme. However, lines that terminate
(Dead Ends) are not extracted. Any thoughts on how I might capture them?

I tried extracting ALL points from the polyline theme, but that gives me
an unwieldy point theme which contains ALL VERTICES as well, which is
not where I'm aiming.

Suggestions on how to extract deadends appreciated.

Kieran,

So, you have 2 point shapefiles. 1 has intersections, 2 has all points.
Select the features from 2 that overlap 1. Switch the selection. Create
shapefile 3 that has all points that are not intersections. Select roads
that overlap shapefile 3. These should be your roads that are deadends.

Good Luck!

DAvid,
I gave that some (thorough?) thought. However, when I use EDTOOLS for all
points, it extracts ALL VERTICES as points. So, along with dead ends, I get
every vertex in the shapefile. Matching that back to the road theme would
put me back where I started, but without the start/end nodes.
I'm toying with the shp2gen script now. I think I can write a script to
parse a GEN file and get the first and last coord of each polyline. However,
when I did it manually, I ran upon some errors. ...perhaps I missed some
data points during the monotony.

I'm wondering if the code to convert a shape from the ESRI API format to

the MapServer format isn't updating the shape extent. Can you get to 
the shape properties via the other query mechanisms or are they all

(The error message makes sense based on the extent values.) I'll check

Dear List,
Maybe this is simple, cause I'm missing something. Maybe not. What I'm

trying to do is to make a simple itemnquery (item/value) get the
results 
and zoom the map to the extent of the result shapes. So what I thought
I 
do is simply place [shpext] in my template file to get the extent and 
use this for creating the new map. Work fine except for the fact that 
the only thing I get back for [shpext] is '-1 -1 -1 -1'. Same for 
[shpmid] or any other extent related informationen about the shape. If
I 
place mapext=[shapes] in my request (just to give it a shoot) mapserver

tells me that it's not possible to generate a valid mapextent from 
selected shapes.

Here is the setting

-qlayer is of polygon type.
-Datasource is SDE (8.2)
-Mapserver is 3.6.1

and here is my request:

http://mymachine/cgi-bin/mapserv? 
map=/var/apache/htdocs/project/myMap.map
&mode=itemnquery
&qLayer=myLayer
&map_myLayer_filter="ITEM='VALUE'"
&map_myLayer_data=SDEUSER.SDETABALE,SHAPE
&map_myLayer_header=templates/searchheader.html
&map_myLayer_template=templates/search.html
&map_myLayer_footer=templates/searchcellfooter.html

Any hint is appreciated.

Message-ID: 

The lakes are all closed polygons. Is it even possible to have an unclosed
polygon in a shapefile? In anycase, I fixed the problem by sorting the lakes
shapefile and then using MAXFEATURES.  It would only happen when I tried to
draw too many lake features at once.  I played with the MAXFEATURES value a
bit until I found a setting that worked.  If I tried to draw over 75 lakes
in the view, it caused the error, but less than that and it rendered just
fine.  I still don't understand why this was happening, but at least I found
a work around.

Thanks,
Jeff

Could those layers contain unclosed polygons?  This is just a wild guess
since I don't know how MapServer handles that type of situation, but
perhaps the large scale views were successful because you happened to be
displaying small regions where all polygons were closed.  Then, when
zoomed to full extent, MapServer throws the error when trying to render
the unclosed polygons (?)

If you have ArcInfo at your disposal you could try converting your
shapefiles to coverages, running CLEAN to build polygon topology, and
converting back to shapefiles.

Yup, wasn't setting the extent of shapes retrieved from SDE. I just
fixed the

you're

pooling
yesterday and while not fully tested it makes a bit of difference with

I'm wondering if the code to convert a shape from the ESRI API format
to

the MapServer format isn't updating the shape extent. Can you get to 
the shape properties via the other query mechanisms or are they all
busted? 
(The error message makes sense based on the extent values.) I'll check
the SDE source now...

Dear List,
Maybe this is simple, cause I'm missing something. Maybe not. What I'm

trying to do is to make a simple itemnquery (item/value) get the
results 
and zoom the map to the extent of the result shapes. So what I thought
I 
do is simply place [shpext] in my template file to get the extent and 
use this for creating the new map. Work fine except for the fact that 
the only thing I get back for [shpext] is '-1 -1 -1 -1'. Same for 
[shpmid] or any other extent related informationen about the shape. If
I 
place mapext=[shapes] in my request (just to give it a shoot)
mapserver

tells me that it's not possible to generate a valid mapextent from 
selected shapes.

Here is the setting

-qlayer is of polygon type.
-Datasource is SDE (8.2)
-Mapserver is 3.6.1

and here is my request:

http://mymachine/cgi-bin/mapserv? 
map=/var/apache/htdocs/project/myMap.map
&mode=itemnquery
&qLayer=myLayer
&map_myLayer_filter="ITEM='VALUE'"
&map_myLayer_data=SDEUSER.SDETABALE,SHAPE
&map_myLayer_header=templates/searchheader.html
&map_myLayer_template=templates/search.html
&map_myLayer_footer=templates/searchcellfooter.html

Any hint is appreciated.
regards
Oliver

I think your layer definition is missing LABELITEM ... so mapserver does not know what labels to draw.

Thanks Ed & Chip, 

I tried to set the layer to type point and the problem persists. 

When I try to use the 'drawLabelCache()' method I get the following error=20 
at the line of the php/mapscript file making the method call - 

Fatal error: MapServer Error in msGetBitmapFont(): Invalid bitmap font. 
Must be one of tiny, small, medium, large or giant. 

Currently I have the annotation layer as the last layer entry in the map=20 
file - and it is still being drawn over by the other layers.  Could it be=20 
how I am defining my other layers?  Here is an example: 

LAYER 
   NAME 'states' 
   TYPE POLYGON 
   STATUS ON 
   DATA 'north_america/usa/statesp020' 
   MAXSCALE 26000000 
   MINSCALE 1 
   GROUP 'north_america' 
   CLASS 
     NAME 'states' 
     OUTLINECOLOR 204 204 204 
     COLOR 255 255 204 
     LABEL 
      COLOR 0 0 0 
         SIZE SMALL 
     END 
   END 
END 

Am I possibly running into a v3.5 issue?

Jeff,

I posted a similiar error with polylines last week. The problem was there 
were some invalid polylines in the shapefile and when they were in the 
visible extent it threw the error. I found them by calculating the length in 
ArcView and found a few with an undefined length. Maybe you could try the 
same with the area.

John,

Yes, this is perfectly doable. MapServer doesn't know or care wether it was
called by a web browser or another app.

Our site uses the technique you describe, and it's been working great for
us.

You can also use the mode=legend (if I remember correctly) to ONLY get a
legend back.

John,

Depends ... in mode=legend, the image is returned "raw" to the client, or
HTML if you use that feature.

Otherwise, it would get written to whatever place you configured as the
temporary directory in your mapfile.

John -

If you use the "mode=" commands to have MapServer generate just the map, or just the scalebar, or just the legend, etc. then the image is written to cgi-bin stdout - that is, back to the caller, so you can use the MapServer URL as the SRC property of an IMG tag, as in:

If you have the legend generated as one of several images in processing an HTML template, then MapServer will write the legend image to the tmp directory (specified in the MAP file) and substitute the URL to that image for the [legend] tag in the template.

Testpoints is a table in the database with a geometry column. It's a
simple layer that contains 7 points. The geometry is held in the
"the_geom" field and when I do a select on the table in psql I can see
that in the "the_geom" field every record begins with "SRID=-1;POINT("

Subject: [Mapserver-users] How to Draw Annotation Layer Last
In-Reply-To: <200301221353.AA1294008522@cshore.com>

TH,

I commented out all the label objects from all the layers except the 
credits layer and still receive the error

Fatal error: MapServer Error in msGetBitmapFont(): Invalid bitmap font.
Must be one of tiny, small, medium, large or giant.

I have upgraded to MapServer 3.6.4 and PHP/Mapscript 3.6 w/ PHP 4.3.0 - 
same results.

I am sure it will end up being something subtle somewhere in my map file or 
php/mapscript code.

Thanks for the help.

Dan

Dan,

Try adding to your LABEL section:

TYPE bitmap

and see if that helps.

Hi,

I am just starting exploring Mapserver.

I modified the demo.map to mydemo.map and works fine, when I start labeling
with one of the attribute called 'LOT' then I can only see the labels on the
map, I can't see the full map.

Subject: [Mapserver-users] Label background scaling problem
Message-ID: <3E2FF157.1B9E2760@ikf.nlh.no>

Mapserver 3.7, nightly 23. january.
(Solaris 2.5.1)
MapServer version 3.7 (development) OUTPUT=PNG OUTPUT=JPEG
  OUTPUT=WBMP SUPPORTS=PROJ SUPPORTS=TTF SUPPORTS=WMS_SERVER
  SUPPORTS=WMS_CLIENT SUPPORTS=GD2_RGB INPUT=EPPL7 INPUT=SDE
  INPUT=POSTGIS INPUT=GDAL INPUT=SHAPEFILE

GDAL 1.1.8
GD 2.0.11
PostGIS 0.7.3
Freetype 2.1.2

I have tried to use labels with a background. I wanted to
scale both the (point) symbols and the labels (with
background) according to the scale of the map (different
scaling for the point symbols and the labels). The symbols
seem to scale OK, the labels seem to scale OK, but the
label background rectangles do not scale the same as the
label text (in my case, they scale "too much", so the
background rectangles become enormous compared to the
text when zooming in). If I set LABEL.MAXSIZE to the same
value as LABEL.MINSIZE and LABEL.SIZE, the text behaves
as expected, but the background box is not affected.

Am I doing something wrong?

(There might also be some problems with label placement
when scaling labels)

I have included some (relevant?) parts from my map-file
below.

Hi
I need to use DBF table joins in MapServer v.3.7.  I just updated my code
with the latest from CVS and I have found the msJoinDBFTables function in
mapquery.c, but I don't see where this function is ever called anywhere.

	- Have joins been activated in the latest code?
		Any information about how they work would 		be helpful.

Thanks!

Hi List,

I've got some issues with labels.

1) I want to label my layer using WRAP as my object =
names are=20
big so they overlap.
 here is my layer def.

# to disply district name  on map
LAYER # =
start of the=20
"label district" layer object
  CONNECTIONTYPE postgis
  =
NAME=20
"dist_label"
  CONNECTION "host=3D34.3.40.1 port=3D343 =
user=3Dtest=20
password=3Dtest dbname=3Dtest"
  DATA "wkb_geometry from=20
test_poly"
  STATUS OFF
  TYPE ANNOTATION
  =
LABELITEM=20
"admin_name"
  CLASS
    NAME=20
"dist_label"
    =
LABEL
      FORCE=20
TRUE
      POSITION=20
CC
      FONT=20
fritqat-italic
      TYPE=20
truetype
      SIZE=20
6
      COLOR 0 0=20
0
       WRAP 20
   =20
END
  END # end of class object
END # end of =
layer=20
object
I get this error when I include "wrap"
Warning: MapServer Error in getCharacter(): =
(20):(259)=20

Any idea??

2) One of the of the polygon does not get labeled, =
although I=20
can query it and get right result.!!!

WRAP refers to a character in the dataset that signifies a carriage return.
For example, you might include a '$' in your label every 20 characters.
MapServer will then 'wrap' the text a that point.

At least that's how I understand that function to work.

Subject: [Mapserver-users] raster image server: optimal performance
Message-ID: <3E300E06.9050006@bvv.bayern.de>

Hello list,

I want to use MapServer 3.6.3 as a raster server for rectified aerial photos
, working on a Linux box (SuSE 8.0), I have also gdal.

For testing, I worked with a dataset of jpg's (plus worldfiles) or
geotiffs.

I have a test dataset of aerial photos (jpg plus worldfile, alernatively
geotiff) of an area 40 x 25 km in 1km-square tiles with resolution 40
cm, i.e. the tiles are 2500x2500 pixels, about 800 tiles.

To get things working at all, I proceeded the usual way
for raster images setting up an index
shapefile (e.g. with gdaltindex). So far, everything OK ...

Now I want to speed up things, as my original dataset covers 200x350 km,
all in 40cm resolution. (IN jpeg 80 GByte, in GeoTiff about 400 GByte!),
   in 1km-squares that would mean 70000 tiles. The files are stored in a
simple file system.

a) I tried out jpeg's vs (uncompressed) geotiffs. With the test dataset,
jpegs (also diskspace-saving!) seemed to perform slightly better. Can
anybody share the experience or give me hints about the best performing
data format?

b) What effect on MapServer response time does the tile size have? Any
recommendations on the list for optimal tile size (bigger means less
tiles) for best performance? Any dependencies on the data format?

c) At the moment, I use b/w photos. What changes do I face in
performance if I switch to color?

Thank you

Hubert

Subject: [Mapserver-users] Create .MAP File Programmatically
Message-ID: <3E300BBB.7070207@softhome.net>

Hello all!

Hopefully this question hasn?t come up too often in the past, but I have 
checked the FAQ, the mailing list archives, the contributed software 
pages, and the Internet without success.

Is there any other tool (preferably open source) that will allow me to 
create a .MAP files from a given set of .SHP, .SHX, and .DBF files?

I am aware of the utility for ArcView on the contributed software page, 
but am still in the process of getting it to work.

I have also investigated MapLab 
(http://www2.dmsolutions.ca/webtools/maplab/index.html) but have been 
unable to find and documentation on how this might be done.

I have also been reading the mapfile specs 
(http://mapserver.gis.umn.edu/doc36/mapfile-reference.html) but have 
found no mention of an automated tool.

Any information anyone could provide would be greatly appreciated.

Thanks in advance!

This is from the mapfile documentation:
WRAP [character]
Character that represents an end-of-line condition in label text, thus
resulting in a multi-line label.

I guess you need to insert a special character in your text where you
want to have it wrapped. 
Example: 

This is a long\line of text

WRAP '\'

wraps to:
This is a long
line of text

Hubert -

This is a complex subject.  The most important thing is to have a good idea of how your images will be used.  You want to always be thinking about how a typical map image request translates into disk reading activity.  In the ideal world, each map image request would translate into opening exactly one source image file and reading consecutive bytes from that file to produce exactly the image you need and no more.  The real world doesn't work that way, but you should always be thinking about how to come as close to that goal as you can.  Here are some thoughts.

1. JPEG is usually a bad idea, relative to GeoTIFF.  That's because the JPEG format requires the entire image to be decoded in order to return a small portion of it.  GeoTIFF allows you to only read a specific portion of the file.  However, if your test images are set up such that you need to read most of each file anyway, you may see little difference.

2. Smaller image tiles with a TILEINDEX are usually a good idea, but don't overdo it.  Disk seek time (going from one file to another) is typically much slower than reading from a single file.  So don't make very small images such that each map image request requires many image files to be opened and read.  Images that are perhaps 2 to 5 times the size of the map image in each dimension might be a good target - that means you'll have many cases in which only one source image needs to be read.  Making the files larger (if they're uncompressed GeoTIFF) isn't really a problem either.  If you make the image files too large, you will end up doing multiple disk seeks inside the file, which aren't as bad as multiple-file seeks but which should be avoided if possible.

3. For aerial photography, TIFFs typically don't compress very much, so uncompressed is fine.  This also eliminates some issues you might have with various compression schemes.

4. For some people it's not obvious that zooming OUT on the image (showing a large area on the map) is much more work than zooming IN on it.  If you expect your users to be viewing zoomed-out images often, look into GDAL's support for image pyramids.  This allows you to create pre-resampled, lower-resolution versions of each image that are automatically used for zoomed-out display.  The disadvantage is that they require more disk space, but you can get significant improvements in performance for only a 15% - 20% increase in storage space.

5. Disk space is cheap - use it.  400GB of good IDE disk storage costs around USD$650 right now, or just about 70,000 times cheaper than the first hard disk I ever purchased .

6. Make sure your testing models the way your maps will really be used.  The zoom level is the most important factor - if your users are mostly going to view the photos at full-scale, test that way.  If they're mostly zoomed out, be sure to test that way, because there are different factors involved.

Good luck!
