Integrating Big Data search tool Elasticsearch into the Arches geospatial web application

Integrating Big Data search tool Elasticsearch into the Arches geospatial web application

When we started developing the Arches Geospatial Cultural Asset Management code base (archesproject.org) we decided upon a graph based data structure. Graphs are particularly nice for the semantic information built into the structure (ie: node x is related to node y by relationship z). But in choosing this structure, you sacrifice a little speed during data access. For example, to relate 2 nodes together effectively requires 2 database joins...

Creating Convex Hulls for geospatial data processing and display in OpenLayers Using Quickhull

Creating Convex Hulls for geospatial data processing and display in OpenLayers Using Quickhull

A while back I was working on a web mapping application that displayed vector features on an OpenLayers map as clusters. To give the user a sense of the cluster extent, I needed to display a convex hull polygon around the vector locations when the user moused over a cluster. However since we were clustering the features in the browser I needed a way to perform this kind of...

The Getty Conservation Institute, World Monuments Fund and Farallon Geographics are excited to announce the release of version 1.0 of Arches, a modern, user-friendly, open source information system created to help organizations inventory and manage heritage places of all types. For those seeing Arches for the first time, the clean and elegant Arches interface might seem a bit simple on the surface. However, looks can be deceiving. Arches is...
eCatch spatial fisheries mapping application gets UI enhancements

eCatch spatial fisheries mapping application gets UI enhancements

eCatch is a tool from The Nature Conservancy (TNC) that addresses one of the most difficult aspects of fisheries management: the collection of good fish location data to allow for in-season adaptive management. eCatch addresses this problem using a web-based app for crowd-sourced collection, mapping and sharing of fishing data. Using eCatch on an iPad, fisherman at sea, report areas where they catch overfished species and learn from other...
Another Great Use of the MarineMap Environmental GIS Decision Support Tool

Another Great Use of the MarineMap Environmental GIS Decision Support Tool

Yesterday, we received a very rewarding email from a colleague who had worked for Farallon on a project we helped the MarineMap Consortium complete a couple of years ago: “Just thought I would pass along an experience that, I hope, may bring a smile to your face. I was in a meeting with some VIP’s today for a petroleum client we are working with. It has to do with...
