[mapserver-dev] - Tile index

[Rahkonen Jukka (Tike)]

Hi,

I would say that a question like this belongs to mapserver-users list. If discussion leads to conclusion that there is a bug in Mapserver the next step would be to create a ticket to github or continue discussion about how to fix it best on mapserver-dev.

My guess is that you do not use the same mapfiles with your 6.4.1 and 6.5-dev on x64 wheezy.
The tileindex should be found from layer "panchro" but the mapfile in your message does not define that layer.

TILEITEM "the_path"
TILEINDEX "panchro"

Hi,
I want to use mapserver with spatial index in postgres/postgis. The mapfile looks
......
LAYER
NAME "footprint"
STATUS ON
TYPE POLYGON
EXTENT -180 -90 180 90
CONNECTIONTYPE postgis
CONNECTION "dbname=test host=X.X.X.X

USING srid=4326"
FILTER "the_geom is not null"

With 6.4.1, everything is ok, raster layer is visible and there is no error in log file.
But when I try to use this mapfile with 6.5-dev on x64 wheezy, only footprint
layer is visible. The raster layer is not visible and it seems non item index is

msDrawRasterLayerLow(raster): entering.

How to defined item index with 6.5-dev ?
Thanks a lot

Hi,

I transfer this question to mapserver-users :
I want to use mapserver with spatial index in postgres/postgis. The mapfile looks like :

......

LAYER
NAME "footprint"

With 6.4.1, everything is ok, raster layer is visible and there is no error in log file.
But when I try to use this mapfile with 6.5-dev on x64 wheezy, only footprint layer is visible. The raster layer is not visible and it seems non item index is defined cf log file below :

......
msDrawRasterLayerLow(raster): entering.

How to defined item index with 6.5-dev ?

Hi Scott,

I managed to get PostGIS tileindex work as follows with Mapserver 6.5-dev:

CONNECTIONTYPE OGR
CONNECTION "PG:dbname=xxx host=yyy port=5432 user='zzz' password='xyz'"
DATA "select * from tindextest"
# FILTER "geom is not null"

and with native connection as
CONNECTIONTYPE postgis
CONNECTION "dbname=xxx host=yyy port=5432 user=zzz password='xyz'"
DATA "geom FROM tindextest USING UNIQUE gid USING srid=3067"
#FILTER "geom is not null"

With both connection types I got this error before I commented the FILTER out:
"msEvalExpression(): General error message. Cannot evaluate expression, no item index defined."

This feels like a bug that could be a side effect of new development made with filters. Make a ticket to Github if you can verify.
