I added aerial imagery from GIS server and created fishnet over the area of interest: I use fishnet as index layer for my data driven pages, making sure the sorting order coincides with record order in fishnet table. I applied script (see below) to travel through pages, export them to temp raster, clip it to PNG raster named after page name. Result shows ...
concerning your question about how to update the bounding-boxes: Choose the layers menu: -- Click on the layer in the layers list: -- Recalculate the bounds If the extent keeps changing you could perhaps try to set the extent manually to the world extent...
By default shp2pgsql does NOT create indexes. You need to pass -I to make it generate a spatial index. http://postgis.net/docs/manual-1.3/ch04.html#id435762 Check if your table has an index by running \d tablename in psql. In the list of indexes should be a line with "gist" (unless you picked a different index) and your geometry column name. You can add ...
GeoServer comes bundled with GeoWebCache. Have a go at truncating that cache. Go to your GeoServer Admin Console in the web browser and choose the 'Tile Layers' section, then go to 'seed/truncate'. You can also do this directly with GWC by going to http://yourserver:8080/geoserver/gwc. See below:
I believe you may want to alter the refresh rate. I have done this to get real time feeds for police/fire/EMS as well as field resources for search & rescue. All of these needed to have a much quicker refresh rate than the default. This will refresh the data every x seconds/minutes. As long as the data that you are serving is being refreshed, your ...
For anyone who is still having this problem, in QGIS 2.10 you can go to Settings > Options > Rendering, and change the Map update interval to be larger. If QGIS can render all of the layers in less than this amount of time, it will update the whole canvas at once, which gets rid of the blinking. If it cannot update all the layers before this interval passes, ...
I think you can make this raster dataset to export it into other formats like image formats (.tif,.png,.sid) and then, you can add all these images into mosaic dataset and run "manage tile cache" to use as like base map or backfill layer.
This probably has nothing to do with Leaflet — it requests tile images the same way as other JS libraries, and caching is fully handled by the browser. Check your browser/devtools settings.
Based on the ESRI documenation (http://server.arcgis.com/en/server/latest/publish-services/linux/accelerating-map-cache-creation.htm) the best practice for the number of instances to use for caching is n + 1 where n is the number of cores running on the server. Your servers have 4 processors each and each X5690 processor has 6 cores according to the ...
