Breaking Radio Silence

Things have been kind of quiet on the blog lately due to things being busy at work. I call that a good problem to have. Since the beginning of the year, I’ve written a a lot of proposals for a mixture of potential customers. Interestingly, I’m seeing a lot more call for “GIS Analyst” work. One trend I’ve noticed, at least in the Federal sector, is that the time between proposal due dates and award announcements seems to be lengthening. That may be an indication of the ongoing flux in funding and organizations try to figure out how to fund their requirements. It will be interesting to see how it shakes out. Of course, it’s good that the opportunities are there in the first place.

One the technical side of things, I’ve been involved in a smattering of things that’s made it hard to roll up one good post. I’m pretty heavily involved in the PIM efforts that my colleague, Barry Schimpf, has been blogging about over on the Zekiah blog. Continue reading “Breaking Radio Silence”

2011 TIGER Boundary Files in SpatiaLite Format

Over on the SpatiaLite Google Group, Stine Consulting announced the availability of 2011 TIGER Boundary files in SpatiaLite format.

Despite initial enthusiasm, mainstream uptake of SpatiaLite has been slow but I think that’s about to change. Large organizations, such as the US Army, are showing a much more serious interest in SpatiaLite as they expand their use of mobile and hand-held platforms.

I expect that increased availability of data in native SpatiaLite databases will also help adoption. So if you need US boundaries data, check out this offering from Stine Consulting. And, if you’re looking for more data for use in SpatiaLite, don’t forget that you can download any dataset available on GeoCommons as a SpatiaLite database.

Configuration Management for Geospatial Data Models

I wanted to take a opportunity to do something I don’t often do, and draw attention to a series of posts that’s going on over on my company’s blog. About a year ago, my company, Zekiah Technologies joined forces with Upper 90 Systems. Upper 90 was probably best known for their work building tools that supported the Spatial Data Standard for Facilities, Infrastructure, and Environment (SDSFIE), which is a data model that is used by the US DOD to standardize the representation of GIS data for the purpose of performing facilities management on military installations.

SDSFIE (PDF) has existed for some time, with several versions of the standard being rolled out to its diverse user community. Through that process, we’ve learned a thing or two about configuration management of widely-implemented geospatial data models. This understanding has been turned into a series of tools designed to help with the issues surround lifecycle management of a data model (as opposed to physical databases themselves).

SpatiaLite 3.0 Beta Is Available

Alessandro Furieri announced the availability of the beta of SpatiaLite 3.0.0 on 17 August. It can be downloaded here: http://www.gaia-gis.it/spatialite-3.0.0-BETA/index.html.

Some of the more interesting additions include additional support for topology and the ability to export GeoJSON.

I did a very quick test with QGIS 1.7.0 and was able to directly access and edit a table in a database I created with SpatiaLite 3.0.0 so that’s initially promising.

The extra island off the coast of Canada was edited in with QGIS.

zigGIS Hotfix Available

Abe announced the availability of hotfix 3 for zigGIS 2.0.5. From the announcement:

Hotfix 3 fixes an issue that prevented point layers from being
editable; it also includes all prior hotfixes. The hotfix is a free
upgrade and is highly recommended for all users. Please go to
http://pub.obtusesoft.com > My Order. After logging in you’ll see a
link to the patch.

Abe is working hard on version 3.0 but obviously is continuing to support 2.x as well. Improvements include a new provider model which will better enable support for other data sources. A roadmap should be available soon.

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.

SpatiaLite Support in QGIS

Alessandro announced on SpatiaLite group today that QGIS 1.1 will include a data provider for SpatiaLite, the spatial extender for SQLite.

It’s out there now in the SVN trunk if you’re so inclined. I am curious how long it will take to cascade through to the OSGEO4W build.

If you haven’t check out SpatiaLite, I highly encourage you to do so. It is powerful and very lightweight.
