You know you've arrived...

…when people start discussing the best way to replace you.

Seen amongst the abstracts in the FOSS4G Community Program Review: “Beyond PostGIS - New developments in Open Source Spatial Databases” and “JASPA, an alternative to PostGIS”.

Is that a bright shining light? I’m floating above my body…

FOSS4G Community Program Review

It’s that time of year again! The Community Program Review for FOSS4G has begun!

If you’re going to FOSS4G, or seriously thinking about going, the review is a way to ensure that the program includes topics you are interested in. You scroll through a list of all the abstracts the conference has received, and select the ones that are of interest to you. The conference committee tabulates all the results and uses that data to help build the program and to slot talks into rooms of appropriate size.

The number of abstracts is a good deal larger than the number of slots this year, so taking the time to do the review is a good idea if you’re planning to attend this year!

Lazyweb: SDE requirements for PostGIS

Oh, lazyweb, I beseach thee!

Can you tell me, for each version of ArcSDE, what version(s) of PostGIS is/are supported? I’m at the Washington GIS conference, and folks are using SDE on PostGIS, and some of them are using old versions of PostGIS, so I need to know how far back we have to apply patches in order to fully support users who have deployed SDE on PostGIS.

Update: The lazyweb responds, with ArcSDE 10 requirements, ArcSDE 9.3.x requirements and recap: PostGIS 1.4.0 for ArcSDE 10, PostGIS 1.3.2 for ArcSDE 9.3/9.3.1

Also, from Cort Daniel of Pierce County I hear that minor releases as late as PostGIS 1.3.7 and PostgreSQL 8.3.5 work (unofficially) for ArcSDE 9.3.

Update2: Cort also said that while PostgreSQL 8.3.5 worked with ArcSDE 9.3, 8.3.7 did not (date fields stopped working right), which is really really odd. Not sure if anyone else could confirm that.

Surveyor's Sermon

Last month I had an opportunity to give a 5-minute “Ignite” talk at Where 2.0 in San Jose. I chose my topic because I fear one of the things missing in the technologist enthusiasm for geolocation, particularly in the population of technically astute but non-geo people, is a respect for how locations are actually derived, and knowledge of the provenance of the data that undergirds our new mapping tools.

FOSS4G 2010 Going to be Big

The presentation abstract deadline has passed for FOSS4G 2010 and there have been 354 abstracts submitted! I’m not sure the exact number of session slots in the planned program, but for comparison 2007 had 120 slots and subsequent events have been similar – that’s about how many 30 minute talks you can fit into two days in a five-track format. In 2007, the biggest FOSS4G so far, we had around 240 submissions for our 120 slots. So, with three submissions for every slot, 2010 is looking like it is going to be gangbusters! Everyone wants to go to Barcelona, I guess they heard about the escudella i carn d’olla.
