• OGC Geopackage [GPKG] on the street

    Posted on January 14, 2013

    I am thrilled to see the OGC Geopackage [GPKG] spec hit the street and see Sandro, Brad and Spatialite taking such a prominent role there. Using Spatialite as the vector reference implementation makes a lot of sense. The spec does seem a little bloated to me. But OTOH, sometimes I... [Read More]

  • Spatialite is my default

    Posted on January 9, 2013

    Like James Fee, and a few others: I love Spatialite and want to use it more. I find myself keeping maybe three 500MB .sqlite files in my Dropbox folder with my favorite and newly found data ready for use. Although I have access to and use ArcMap at home and... [Read More]

  • ogrinfo and gdalinfo script to document data

    Posted on November 29, 2012

    I needed to recursively document a bunch of Shapefiles and geotiffs in a hierarchy of directories (soon file geodatabses). I can’t use Arc*anything so I’m using ogrinfo and gdalinfo in many directories. I started using xargs, but ran into weirdness beyond white characters, and involving bash string manipulation (I’m running... [Read More]

  • Improved File Listing Script

    Posted on November 5, 2012

    Run this anywhere and it will recurse through your directories and make some readable output of your files. It’s set to list interesting things for GIS data. I also finally got it working where it will find all the .zip files and list their contents on most environments – even... [Read More]

  • Spatialite and Triggers to Update Data

    Posted on October 19, 2012

    I finally decided to do a little demo here of a common feature I need on a lot of projects. We often have systems that maintain point locations of things (create, update, delete, view them) and having attributes of spatial relationship automatically applied to them is often quite handy. For... [Read More]

  • First ever LOL

    Posted on June 18, 2012

    I’ve never used the acronym LOL in a message to anyone before. But I did LOL when I read this (and still am LOLing) and so I sent this link to a few selected colleagues. This won’t make sense to you unless you use ESRI products or are a GISer.... [Read More]

  • List my files

    Posted on June 15, 2012

    About three times a year I need to make a listing of files in a directory. Usually this is because I need to do something to them and I need a checklist. Or I just need to tell someone what files are there. [Read More]

  • Recent Spatialite News May 2012

    Posted on June 3, 2012

    The primary outlet for spatialite news and changes is the Google Groups Spatialite user mailing list. This is a low-barrier place to announce things. But it can be a little tough to use to understand the trajectory of the project. So, I might take some time every now and then... [Read More]

  • Convert Android .3GP movies to .MP4 on windows

    Posted on May 25, 2012

    Hardly any software works well with .3GP movie files. So, with this collection of movies accumulating in my phone sync folder I needed something to convert them into formats that are more useful (like video editing software or upload sites). So, here’s a little quick and dirty solution for batch... [Read More]
