[Qgis-user] Get_Qgis_to_read_sid_files

2017-07-28 Thread carto 

  Greetings List;


  I am new to Qgis, tho not to GIS generally.   I thought I may post 
this question; apologies if not the proper venue, but I perused the 
earlier threads to see if it was proper, and perhaps find an answer.


I am trying to get Qgis to read .sid image files.

  I am using a macOS, 10.11 (el cap).
  Qgis  2.18.7

My understanding so far, this is the order of install.
  Qgis (of course)
  GDAL_Complete-2.1
  GDAL-MrSid_plugin-2.1.1

  (all from KyngChaos)

  They all installed with no errors (good, but errors still possible), 
but now the part I do not understand:
   In the readme for the MrSid plugin above, now I must obtain DSDK file 
from Lizardtech:


MrSid_DSDK-9.5.4.4703-darwin15.universal.clang70.zip

  I am told to simply copy and paste the files from the .zip; I guess 
keeping the file structure, but where do they go?


  Again, within the GDAL MrSid readme file, it directed to copy only 
four files to Library, but now I am told all the files need to be copied 
somewhere.


  After this, then two sudo commands (also in the GDAL MrSid readme)

  Related to this (perhaps), the GDAL 2.1 install went into the root 
Library  (  /Library  ) and not the user  ( /users/userme/Library  ).   
I know enough of unix to be dangerous, but not proficient.

 Would this be related?

   Hopefully I made some sense of my question.   I can elaborate 
further.   There is probably a simple fix for this; so apologies for the 
newbie question.


   Thanks and Regards,

Re: [Qgis-user] features visible in attribute table but not identifiable

Hi,

I am using QGIS 2.18.11.
When editing a shapefile I noticed a specific error.
Some features I added where not styled after adding but did show up in the 
attribute table.
When I zoom to the selected feature in the attribute table the parcel shows up.
When I try to identify them with the identify tool the features are missing.
Anyone has an explanation or similar experience?



It might help to run "Check vailidity" from the vector menu. Features 
with invalid geometry might not get rendered, but are in the attribute 
table.


HTH,

Re: [Qgis-user] ilike-operator

2017-07-28 Thread Walter Nordmann 
please try it. it does work! qgis filter is usually accepting all valid 
sql queries.


filter: lower("value") similar to '(berlin|london|paris)'

Thanks! Just erased the wildchars to shorten the code.
I forgot to mention that I'm trying this as a QGIS (v 2.18.7) filter, 
not in ProstgreSQL. There, I have only "ilike" as suitable string 
operator, it seems.

Best,
Torben

try this:

https://stackoverflow.com/questions/4928054/postgresql-wildcard-like-for-any-of-a-list-of-words#4928415

|lower("Shape")similar to'(rectangle|triangle)' should do it. Regards 
walter btw: why are you using ilike without wildchars? |

Hello,
is there a more elegant way for saying the following:
"Shape" ILIKE 'rectangle' OR "Shape" ILIKE 'triangle' ?
[obviously "Shape" ILIKE ('rectangle' OR 'triangle') does not work]
Many thanks!
