At These Coordinates

My article on comparing American Community Survey (ACS) estimates over time was published earlier this month.

I posted the latest version of my Introduction to GIS with QGIS tutorial manual, updated for QGIS 3.44 Solothurn.

I presented a poster last April on the library’s GIS and Data Services at the CHAIRS-C conference at the Brown School of Public Health.

I haven’t been keeping up with posting, as these past few months have been atypical.

Last December, the Data Rescue Project (DRP) finished an initiative to download and archive over 400 geospatial data layers from the defunct HIFLD Open repository to DataLumos, an ICPSR-sponsored repository for federal government datasets.

While spending February buried under snow here in Providence, I took the opportunity to update several of the data products we create here at GeoData@SciLi.

I recently revisited a project from a few years ago, where I needed to extract temperature and precipitation data from a raster at specific points on specific dates.

Some good news to end the year: the Data Rescue Project has finished archiving all of the GIS data layers that were in the HIFLD Open portal, which was decommissioned at the end of summer.

I visit courses to guest lecture on census data every semester, and one of the primary topics is immigrant or ethnic communities in the US.

Just when we thought the US government couldn’t possibly become more dysfunctional, it shut down completely on Sept 30, 2025.

Last year I wrote about my stamp collecting hobby in a piece that explored maps and geography on stamps.
