This presentation will discuss enterprise web mapping and mobile applications that we’ve been developing for large utilities and communications companies, based on a number of open source geospatial components, including PostGIS, MapFish, GeoServer and Leaflet. It will discuss development of offline mobile applications using both PhoneGap to compile to native . . .
The rapid growth of traditional and social media, sensors, and other key web technologies has led to an equally rapid increase in the collection of spatio-temporal data. Horizontally scalable solutions provide a technically feasible and affordable solution to this problem, allowing organizations to incrementally scale their hardware in tandem . . .
According to its creator, Yukihiro “Matz” Matsumoto, “Ruby is designed to make programmers happy.” While it may not achieve this goal for everyone, it works for at least one programmer (me). When developing spatial applications however, the seeming lack of support for Ruby can serve to diminish programmer happiness. The . . .
The challenges that are most commonly discussed by proponents of open source in government technology relate to changing the culture among technical staff and explaining the value of open tools and systems. But beyond the political concerns and misperceptions, there are practical complications in implementing these tools inside proprietary tech . . .
The Integrated Land and Water Information System (ILWIS, http://52north.org/communities/ilwis/) is a GIS and remote sensing software integrating raster, vector and thematic data set processing into a desktop application. ILWIS is hosted under the umbrella of the 52North project and managed and maintained by ITC, University of Twente, The Netherlands. ILWIS . . .
Aimed at developers and end-users, this presentation will cover the current state-of-the-art of OpenDroneMap, toolkit of FOSS computer vision tools aiming to be easy to use for referencing unstructured photos into geography data (colorized point clouds, referenced photos, orthophotos, surface models and more), whether the images be sourced from street . . .
This talk will introduce the Tilez project, which provides a
Node.js-based realisation of a Tile Map Service tiles in both GeoJSON and
TopoJSON formats. This formats provide a seamless and highly performant user
mapping experience in both OpenLayers and Leaflet.
The key to fast display of vector geometries in Tilezz lies in the . . .
Nowadays we see, specifically on the Web, maps that are interactive, creative, as well as beautiful and effective. And more and more these maps are no longer “drawn”, by hand or computer, but “coded”. Programmed.
In this talk we show that with modern programming tools, such as the popular D3 API, . . .
The EarthExplorer (EarthExplorer.usgs.gov) system provides on-line search, order, browse and download of Landsat, aerial, LiDAR, and a multitude of other earth science data in support of the United Stated Geological Survey (USGS), Earth Resources Observation and Science (EROS) Center. Last year, the launch of the Landsat 8 satellite has . . .
GIS was born in part by rejecting the strict requirements of surveying, instead blindly digitizing paper maps, which despite their imprecision gave us access to tremendous volumes of digital data. Similarly, great innovation is happening today by discarding precision and standardizing on geographic coordinates to a fixed datum, as commonly . . .
