Geoprocessing in Arc

Soil Erase Script Output


This simple image is the result of a model created in ModelBuilder. The model was designed to exclude soil, previously identified as not prime farmland, from a given basin.

Lahars

Lahar Inundation Areas


Using two USGS 30 meter DEM's, the rivers shown here were extrapolated using a few tools in ArcMap's Spatial Analyst extension. These rivers can then be used to locate potential lahar inundation areas and as a tool in hazard assessment.

Lahar Hazard Assessment


This map identifies at risk population by US Census block groups and schools within a half mile of streams and rivers located on Mt Hood. In the event of a volcanic event, these areas have the highest probability of being impacted by lahars.

Intro to Python


This is a screen shot of the file folder paths created by running a Python script. This script accomplished in seconds what had been a tedious and time consuming task in the past. I'm kind of excited to learn what else I can do with Python.

Applying GIS to Parcel Management



The GIS application that interests me the most is parcel management. This application falls under Land Administration. The typical problems that are addressed with parcel management are land ownership and parcel boundaries. A local property appraiser uses GIS to relate their Computer Aided Mass Appraisal (CAMA) System to the county’s tax parcels. Utilizing GIS reveals any geographic relationships between tax parcels that would otherwise be impossible for the appraiser detect in a standard DBMS. Parcel management is interesting to me because it is the foundation upon which all other GIS analysis is based. For example if we wanted to determine how many houses in a certain area might be affected by the flooding of a nearby river, we would want to use the information from the CAMA System related to the parcels in the GIS. During the course of this class, and the remainder of this program, I would like to learn more efficient methods and work flows with regard to the CAMA System and GIS.
