Open Data Management – Key to Open Data Utility

Open data is wonderful. But we must do more than simply make data available and place it on an FTP site. To make open data truly useful, we need a number of things which are not evident in most open . . . → Read More: Open Data Management – Key to Open Data Utility

Wide Area Information Systems with a Purpose – Aviation, Oil & Gas, etc.

The commercial aviation sector has coined the term SWIM, which stands for System Wide Information Management. In a SWIM system, there are many information services that are widely distributed and which are dynamically integrated to provide global access to information . . . → Read More: Wide Area Information Systems with a Purpose – Aviation, Oil & Gas, etc.

Registry Service as a flexible GML Server

For many people, the OGC Web Feature Service (WFS) is the canonical GML data server because it is almost always used in this way. But there is an alternative means of using GML, and of serving GML data, that is . . . → Read More: Registry Service as a flexible GML Server

CRS Registry Supports Well-Known Text

Recently, the IOGP (International Association of Oil and Gas Producers) announced support for the Open Geospatial Consortium’s (OGC) Well–Known Text (WKT) encoding for Coordinate Systems (see http://www.directionsmag.com/pressreleases/iogp-releases-coordinate-reference-system-definitions-in-well-known-text-fo/427321). . . . → Read More: CRS Registry Supports Well-Known Text

Why Does The Registry Part Matter?

In previous articles, we looked at the value of the CSW-ebRIM data model and took some pains to separate the ideas of the data model from the notions of a catalogue or registry — see “Richer Semantics for Geography – . . . → Read More: Why Does The Registry Part Matter?

Feature Equivalence and Canonical Representatives

According to ISO 19109 (General Feature Model), a feature is a model of some real world entity or phenomenon. Features can be concrete entities like buildings or roadways, abstract ones like municipal boundaries or even temporal events like the occurrence . . . → Read More: Feature Equivalence and Canonical Representatives

Richer Semantics for Geography – CSW-ebRIM

When I was first working on the Geography Markup Language (GML) in 1998, I was much taken with the efforts of the Resource Description Framework (RDF) and associated RDF Schema (RDFS) to incorporate greater meaning into the description of things, . . . → Read More: Richer Semantics for Geography – CSW-ebRIM

Registries for GeoINT

Using geospatial information for effective and actionable intelligence may depend as much on semantics as is does on geography. Knowing a threat location is of interest, but that information is enormously more valuable if intelligence sources can easily classify the . . . → Read More: Registries for GeoINT
