Let’s be honest. There’s some un-coolness to GeoServer. It’s built on Java. It’s old(er) and multi-purpose. It has none of the cache of server side javascript or GoLang goodness. But bless me, it is a workhorse. And sometimes having a tool that can do anything is a blessing. If multi-purpose toolbelts and pocket protectors are uncool, then declare me uncool. You won’t be the first. … Continue reading Take that, hipsters. Compositing in GeoServer
The nice thing about setting up something like GeoServer, which is so feature rich, is when you need to pivot based on the demands of a new project, the technical infrastructure is already there, just waiting to be configured or turned on. The case today: feature services. Someone wants to use my existing infrastructure in a new application. I typically serve tile services. One checkbox … Continue reading Serving and filtering #GeoJSON from #GeoServer
A perennial favorite on this blog is “GeoServer and efficient delivery of raster data (image pyramid layer)“. I am neither the last nor the first authority on this topic (check the GeoSolutions blog for authoritative work on GeoServer and raster, also look to the GeoServer documentation), but I’ve had some good experiences with serving rasters in GeoServer, especially using image pyramid layers Read the original, … Continue reading GeoServer and efficient delivery of raster data (image pyramid layer) (update)
I said it in the title, I’ll say it again, SLDs are not just for ugly maps. I’ve heard from several professionals in this geospatial sector that CartoCSS is so cool– “look at the great cartography you can get out of it”. And, truth be told, creating a standard for cartography that aligns so well with existing web development standards is a brilliant way to … Continue reading Advanced Cartography in #GeoServer– #SLDs can make for very pretty maps
I wrote an earlier post on using GetFeatureInfo through OpenLayers to bring back a formatted html document with pictures, and formated tables, etc. It wasn’t sophisticated, but got the job done. Since around that time, as I’ve been building out our services, the speed with which a GetFeatureInfo request returns has g o t t e n p r o g r e s s … Continue reading OpenLayers, GeoExt, GeoServer, and GetFeatureInfo
I have two previous posts on using MapFish (in this case, the GeoServer version) to allow for printing to hi-resolution PDF maps from the browser. Here we use a command-line browser (cURL) to post our json to the MapFish service in order to retrieve our PDF. I did not keep any notes from before on making json posts to the MapFish server as a means … Continue reading Building simple clients for MapFish — cURL as a client
I’ve had a couple of other posts (1 and 2 and 3 and) on simple clients for MapFish. I like the client server infrastructure for MapFish– with the client end of things built up in GeoExt, it makes for a really elegant combo. But I’d like articulate my vision for simple clients for MapFish a little further. One thing that seems quite feasible is to … Continue reading Building simple clients for MapFish — Beginnings of a PL/pgSQL function
A while back, I had a (somewhat cryptic) post on OGC services and security. A couple months later, I saw this post on GeoSolution’s site on GeoServer security and the ins and outs of various options, from native to proxied security. It is quite a bit more nuanced than my own… . I recommend you read it, even if you don’t use GeoServer– it is … Continue reading #OGC Web Services and #Security
In order to build simple clients for the MapFish print service, we have to understand what the protocols are that are invoked and how they function. To do this we can read the MapFish Print Module Doc, and then modify and vamp from there. While I was going to joke that this would be an excellent cure for insomnia, the joke fell apart when I … Continue reading Building simple clients for MapFish — Underlying Infrastructure
