[mapserver-users] Raster Data

Hello, I have a png raster image that I am adding to GeoMOOSE and it is about 3GB in size. It takes about 10 minutes for the image to show up because the file is so large. What is the best way of dealing with large images like this? Thanks, Jenna -- View this message in context:

Jenna, My first thought would be to convert it to a jpeg compressed tiled geotiff using gdal_translate, and then add overviews using gdaladdo . http://www.gdal.org/gdal_utilities.html Doug On Wed, Mar 12, 2014 at 10:42 AM, jcwalz jennaw...@co.stevens.mn.us wrote: Hello, I have a png

Re: [mapserver-users] Raster Data

Hi, Standard recipe is to use tiled tiff file with overviews, perhaps both compressed. Uncompressed: gdal_translate -of GTiff -co tiled=yes -co bigtiff=yes image.png image.tif gdaladdo -r average image.tif 2 4 8 16 32 64 128 256 You may want to save space by making a compressed tiff. If it is

I also still recommend what Doug, Andy, Jukka say: for display speed in MapServer, make sure all your files are in the mapfile's output projection, and then convert your images to GeoTIFFs and add overviews. -jeff -- Jeff McKenna MapServer Consulting and Training Services

[mapserver-users] Raster Data from PostGIS

Re: [mapserver-users] Raster data performance

Hi Alex, I tried some of the performance tips you mentioned, e.g. converted the .txt to a tiled TIFF to optimize performance. I can not see significant changes in rendering speed. gdal_translate -co TILED=YES input.txt output.tif The major brake still is the expression stuff. I really wonder
