We have adapted the NASA Ames Stereo Pipeline (ASP) – a suite of automated, open source, command-line photogrammetry tools originally developed for NASA planetary missions – to process high-resolution stereo satellite imagery of the Earth. These tools are multithreaded, memory efficient and scalable, which enables processing of “big image . . .
This talk is intended for GIS users & managers who may be interested in open source GIS but aren’t sure what the advantages to them might be, or who think Open Source GIS is nice in principle but are afraid there’s no space for it in their workplace. In general, . . .
MapServer is a fast, flexible and extremely powerful tool for creating dynamic maps for the Web. Underneath the hood, MapServer offers many powerful and advanced features that many users never dig into, and new features are being added constantly. Come learn about some of the more advanced features of MapServer, . . .
Crowdsourcing is known as a way to gather information and data from the general public. In last few years crowdsourcing has become the cheapest and one of the most efficient ways to gather data. With the increased availability of smartphones and smart devices, the general public carries a communication device . . .
Apache Lucene is a Java toolkit that provides a rich set of search capabilities such as keyword search, query suggesters, relevancy, and faceting. It also includes a spatial module for searching and sorting with geometric data using either a flat-plane model or a spherical model. The capabilities therein are leveraged . . .
Your staff keep talking about this “PostGIS” thing, but what is it? Does anyone (important) else use it? What for?
This talk gives a brief overview of the place of PostGIS in spatial IT architecture, how PostGIS compares to proprietary alternatives, who is using PostGIS, and how organizations transition to open . . .
Maps appear all over the web but the core structural language of the web—HTML—does not natively support them. Adding dynamic or interactive maps to a web page or web application can involve complex JavaScript code that is difficult to reuse between contexts.
Web developers are starting to have opportunities to change . . .
Developing an application with the capability to view, collect, and edit geospatial data in connected, limited connectivity, and disconnected environments was a necessity for the ROGUE project. The first version of the application was developed using Cordova/PhoneGap, with everything written in html, css, and javascript, using OpenLayers 2.13 as the . . .
AngularJS is rapidly gaining popularity and favor in the front-end web development community. Several open-source AngularJS wrappers exist for open and closed source web mapping libraries. This session will survey the landscape of existing mapping library wrappers. Wrappers for OpenLayers, Leaflet, d3, Google Maps, and Esri WebMaps will be . . .
Long gone (hopefully) are the days of replicating the “professionals only” desktop GIS interface in a browser. However, with modern browsers, HTML5 APIs, and increased efficiency of javascript engines it is possible to performantly replicate GIS functionality in a purely client-side browser application. Moderately complex geoprocessing, persistent client-side storage and . . .
