Image Mosaics & Automation
by Jonathan Meyer
Need to expose thousands of geo-referenced images with ability to constrain the mosaic by temporal, spatial or custom attributes? GeoServer provides out-of-the box support for this capability and we will walk through a quick set up of GeoServer and configuration of a sample mosaic.
Presentation will include a brief overview of the dataset used, the FOSS stack selected, examples of WMS queries, as well as a live demonstration on the initialization of the complete stack using Docker Compose using GeoServer's REST API. We will highlight areas where performance can be optimized and how to avoid potential pitfalls.

Building high-res satellite imagery metadata tilesets at global scale
Переглядів 2668 років тому
by Brett Marraccini Even though high-res (raster) satellite imagery scenes are more readily available for viewing in online, desktop and web map applications, end-users are still struggling to find the answer to their most important question regarding the imagery: "When was this image collected?". Using open-source geotools such as Python, node.js, github, QGIS and the Mapbox platform we were a...
HHypermap: A Platform to Enable Geospatial Search
Переглядів 2458 років тому
by Ben Lewis There is currently no comprehensive search capability for online spatial information, a critical body of data which now represents an uncurated, “dark web” of data services and data files. One could argue this domain is not even a web since most of it does not link out and most is not linked-to from elsewhere. Though there are millions of geo-services and datasets just a click away...

Surfing the Imagery Tsunami: data exploration with high-frequency Planet Labs imagery
Переглядів 1168 років тому
by Robin Kraft If you had medium-resolution imagery of the whole world every day, where would you look? What would you do with it? It can be overwhelming to think about, but at Planet Labs this is always on our mind as we finalize our constellation. And we want to make it easier for others to think about it too, through open data and open source tools. In this talk, we'll show off what high-cad...

Spatial Data Processing with Docker
Переглядів 7708 років тому
by Sophia Parafina One of the major hurdles of using FOSS4G is that compiled software may not be available for your operating system or that the software has dependencies that the OS may lack. In the past, the solution has been to: 1. go through the process of building and installing the software locally using a package manager 2. using an OS specific distribution such as Portable GIS or OSGeo4...

Automated High Resolution Land Cover Generation from WorldView Multispectral Imagery
Переглядів 3218 років тому
by Craig Stutts To date, many efforts in generating reliable land cover classification from multispectral imagery (MSI) have focused primarily on 30 meter resolution Landsat imagery. At this resolution, it is possible to differentiate large scale man-made and natural features including cities and forests, however, higher resolution objects are difficult to extract. We present a neural network t...
Migrating from Google Earth to Cesium - How to begin your closed-to-open source success story
Переглядів 1,6 тис.8 років тому
by Hannah Pinkos From 2008 until recently, the proprietary Google Earth ecosystem was the primary tool for 3D geospatial visualization on the web. However, Google announced that support for the Google Earth API and Google Earth plug-in will be discontinued early in 2016. As a result, many developers have looked to open source and open standards as a replacement solution in order to avoid the ve...

does measurement tool can run on wmts, only wmts as a baselayer without osm?
ua-cam.com/video/_dmH2jFdewo/v-deo.html, we offer dynamic vector tile solution. more tile format, more function
Dynamic vector tiles support multiple types of data sources, including ArcGIS SDE, shapefile, GeoPackage, etc. They support fully dynamic generation as well as configurable caching strategies.
Is python API available for aloha software?
Methodology? Process?
Super helpful overview thanks!
Great explanation! You covered all the limitation in every architecture. Good work!
Hey, where is the info on this software, where can we get it?
Thank You for sharing your hobby, very cool. The people need to have the power to locate and preserve, not just the gov't avenues. I often find that history is not best shared thru museum glass - but by immersion
Was the demo map updated? The buildings are still broken even the showcase one.
Fixed the showcased relation. My first edit in North America hurray. :) If I had JOSM available right now I would fix more.
Interesting talk, the map is a bit difficult to find, here is the link(it's also in the description): demos.cesium.com/NewYork
Can u provide a link for code plz
Tip: use Mapillary to collect, contribute street-level images. Mapillary integrates nicely with OSM; Mapillary images available in OSM edit mode.
How did you get the duration for flights? I can't find it anywhere on openflights

Hi Hannah, Just wanted to let you know. almost three years later your video helped me to jump start my Cesium development to be viewable on iOS devices. Big thanks to your work!
hello, im interested in those kind of products. How may I contact you?
how can i share my county's data with you? In turn, with whom do you share that data (ie, google? mapquest? etc).
Really great video, but the audio is a little quiet.
Why are you speaking so fast? Irish going American accent at the speed of a bloody Concorde.

We use the book by Shelito that she mentions. Not sure why she would say it's "not about GIS", it absolutely is. Sure it starts with Google Earth and some "geospatial technologies" but I think it's a great introduction to GIS.
What's the name for the Geomesa Dashboard at ua-cam.com/video/O2hT7rzZicA/v-deo.html?
i think it's stealth www.ccri.com/case-studies/stealth/
Nice explanation. Could you please share the queries in comments
Great video covering new features of PostGIS. By the woman who wrote the book on PostGIS. No wonder she is so well informed. :D Thanks Regina Obe
Very useful videos on my favorite technos geoserver and openlayers :)
how to implement?
Its really a fantastic work. kindly share link to access the software
Hi Sir, thanks for the lecture. I am a basic programmer. i use leaflet and postgis , geoserver for mapping. Now i had a work to display huge data (55 MB geojson) on the map. I am trying to undertand the vector tile mapping. But there is no clear excercise in the youtube from start on how to develop a vector tiles from database output and display on browser using leaflet js. Can you please explain or give some reference. thank you
How can i set the color of each city is not the same
is Regina Obe the presenter in this?
Oh and Anita Graser - anitagraser.com/ -is working toward textbooks.
This is great. A really good set of ideas for structuring labs.
Very Nice expaination
way to fast spoken! A pitty, sice it is an awesome topic.
Setting Playback speed to 0.75 actually works pretty well
from 25:21 the audio is heavely distorted
