SpatiaLite Provider Now In SharpMap Repository

I got a surprise e-mail from Felix today letting me know that the SpatiaLite provider I posted some time ago, along with Kev’s great spatial index work, has been included in the SharpMap repository. If you’re looking for one place to pick them up, now you’ve got it.

If you haven’t checked out SharpMap or SpatiaLite, I highly recommend both.

gvSIG Extensions Available

My inbox has been busy this week with announcements from gvSIG. New builds of the network extension and the 3D extension have been released.

New features of the network extension are described as:

“- Create and define network topology (using velocities, or sense of direction, modified costs, barriers, turn costs …)
- Calculate shortest path
- Travelling Salesman Problem (TSP)
- Origin – Destination matrices
- Service Areas
- Emergency / Nearest facilities provider
- Minimum Spanning Tree (MSP)
- Trace (back and forward) the network and find events on the network.”

QGIS 1.4.0 Released

QGIS 1.4.0 has been released. As Terry mentioned on Twitter, that news seemed to get lost amongst the discussion of the GeoDesign Summit and the rebranding of ArcGIS 9.4 to 10.0. I have made use of QGIS in the past and have been perusing 1.4.0 lately. I must state that I am not an analyst nor do I play one on TV but I have been very happy with this release.

First Thoughts on ArcGIS 10.0

The announcement that ArcGIS 9.4 is being re-christened as 10.0 leaves me feeling somewhat bemused. I have seen the new version of Desktop and it is nice and will finally update the current Office-97-feeling UI. The list of changes coming in 10.0 (published so far) is impressive but I haven’t seen any discussion of the changes coming to the ArcGIS architecture, which is of greater interest to me as a developer and integrator. Given the past history of ArcGIS, calling this release 10.0, in my mind, implies a significant architectural shift. ArcGIS 8 was a clear departure from the previous releases of ARC/INFO. Indeed, it not only came with a new version but introduced the name “ArcGIS.”

Foursquare – Teetering On the Edge of YASN

I read with interest this article that was brought to my attention by @gis_Todd on Twitter. I have been playing with Foursquare for a few weeks now and I think this article is in sync with some observations I have had about it but also misses the mark on one key point.
