The IRDIAC site also hosts the Southwest Regional Gap Analysis Project (SWReGAP) landcover and related products and all of the landcover data collected in the field for this project. I didn't have much to do with the SWReGAP project, but I did put together the web mapping application on the website.
I also built (and IRDIAC hosts) two applications for the Utah Governor's Office of Planning and Budget. The state funded graduate students at USU to come up with the models and I implemented them on the web. The first of these is the Utah Critical Lands Mapping Tool (main State page, actual tool), and the second is the Fiscal Impacts Illustrator (main State page, actual tool).
I finished up a Data Extraction Tool for the Agricultural Research Service Forage and Range Research Lab in Logan within the last year. This tool allows users to extract environmental data for points anywhere within the lower 48 states (and eventually Alaska). This will be really useful to researchers who have GPS coordinates of locations (where plant speciments were collected, for example) and need environmental data for analyses (to try and predict more locations where a plant might grow, to stick with the previous example).
Another project I'm really excited about, and is going to be a work in progress for a long time to come, judging by all of the ideas we have for it, is a data viewer for Utah. Virtual Utah has a few unique things about it that have been getting people's attention. Hopefully I find time to add more cool stuff to it soon.
I don't really have anything to show off from Terra Solutions yet, but hopefully that day will come. The company is owned by a good friend of mine and I do help out with projects there occasionally.
I used to do a lot of development for ArcView GIS 3.x. Some of the extensions I wrote for ArcView are available on my ArcView Extensions page. One of the available extensions, StatMod, was my thesis project for a Master's degree in biology, and it later won first place in the ArcView/Avenue category of the User Applications Fair at the 2003 ESRI International User Conference. This extension interfaces ArcView GIS with SAS and S-Plus in order to do logistic regression and classification & regression tree (CART) models. Another available extension, LinkViews, allows the user to link two ArcView views geographically. This extension won second place in the ArcView/Avenue category of the User Applications Fair at the 2003 ESRI International User Conference.
I used to work for the Intermountain Herbarium on the Utah State University campus, and I still do small projects for them occasionally. Two of the most visible projects I've done for the herbarium were to help set up the Grass Manual on the Web and to write the code that created the range maps for the Flora of North America, volumes 24 and 25. I also designed several of the databases that they use internally (including the one that contains the data for those two volumes of Flora).
