If the source data classification scheme is not already strong in prioritizing features how we want to view them, then style . . .
CartoCSS is becoming an ever more popular – and ever more powerful – tool for cartographic and data styling. In this talk, Stamen designers and technologists will present some tips and tricks to make your next design sing. Tips and tricks covered include, but will not be limited to: pixelation, . . .
In addition to hosting the popular OSM-base Toner, Watercolor, and Terrain tile sets, Stamen incorporates custom cartography into much of our client work. This is a behind-the-scenes walkthrough covering the evolution of our rendering infrastructure and the peripheral services that help to make our work unique. Topics covered include the . . .
After creating a custom application featuring ArcSDE and the ESRI Mobile SDK for use by the field crew from a local Mosquito and Vector Abatement District, we sought an alternative to the high overhead from the proprietary software. By utilizing GeoTools, GeoServer, and GeoGit, we were able to develop . . .
The presentation will provide an insight of the new functionality available in the latest release of the software. Publishing and managing spatial metadata using GeoNetwork opensource has become main stream in many Spatial Data Infrastructures.
GeoNetwork opensource 3.0 comes with a new, clean user interface based on AngularJS, Bootstrap and D3. . . .
Area-based planning processes are rapidly moving from paper and desktop GIS based processes to online applications offering real-time analysis and feedback. Users want an interactive and informative experience allowing them to generate reports and analysis without needing to understand the subtleties of GIS or spatial analysis. They expect a . . .
