Give Me a Standard, Any Standard

by

I’ve spent the last year or so doing very little with geospatial technology, but I find myself missing it tremendously. Of course “in my blood” and “how I’m wired” and similar aphorisms apply to how I’m feeling, but that’s not what really has me missing geospatial. In a shocking (for me) turn of events, I find myself missing the influence of OGC on the geospatial technology community.

I’ve spent the last year working on integrating several SaaS systems, including Stripe, Salesforce, NetSuite, and others. I’ve touched upon this in previous posts. All of them implement some form of REST API, but fostering interoperability doesn’t seem to be a primary purpose of those APIs as much as is the enablement of a proprietary partner/strategic-alliance ecosystem. As a result, these APIs, while generally well-documented, are essentially arbitrary. They implement the HTTPS+JSON pattern in the same way that many written languages implement the Roman alphabet. I can sound out the words, but I don’t really have any idea what I’m saying.

OGC Abandons the Web

by

Those are my words, not theirs.

It came to light today that OGC has decided to withdraw the GeoServices REST Specification, also known as the “ESRI REST API,” as a proposed standard. I will not take up the relative merits of the specification or the implications of OGC potentially adopting an industry-developed specification that has so much implied workflow embedded in it. With this decision, three facts remain unaltered:

  1. The ESRI REST API will continue forward as a widely-used de facto standard in the form of ArcGIS Server installs and other emulations, such as that in Arc2Earth.
  2. GeoJSON will continue forward as a widely-used de facto standard in the form of numerous open-source implementations.
  3. OGC still has no JSON syntax.

Yes, twelve years after the birth of JSON, five years after the release of the ESRI REST API and its embedded JSON syntax, and five years after the release of GeoJSON 1.0, OGC is still has no entry in the JSON space. Between Esri and GeoJSON, the utility of JSON in web mapping applications has been roundly proven. In the ESRI arena, find me anyone who willingly uses the SOAP API these days while the adoption of support for GeoJSON across the open-source GIS world speaks volumes. The industry has voted with its feet and its code as to what it prefers.

Comment Period Open for GeoPackage Specification Draft

by

The Open Geospatial Consortium (OGC) has published a draft GeoPackage specification for comment. The GeoPackage specification attempts to create a non-proprietary means for packaging and exchanging all geospatial data in all its forms (vector, raster, and tiles). A couple of things that jump out at me:

  • It calls out SQLite as the reference implementation of a GeoPackage container
  • It calls out SpatiaLite 4 as the reference implementation of a vector feature store
  • It does not call out a reference implementation for rasters or tiles
  • It does not mention exchange of cartography.
