Custom Android app development for field data collection, surveying and navigation purposes (2026):
Above: Samples from a minimal camera application that embosses pictures with relevant GeoSpatial data, device bearing, filename and a graphic representation of location within boundary. Produced with Android Studio Panda 4 and Gemini.
Above: Screen captures of a lightweight GeoSpatial PDF reader made in Android Studio Panda 4 and with Gemini. Specifically for utilizing user imported Geospatial PDFs and with basic field data collection functions like importing, exporting and creating georeferenced point and polyline data, and basic navigation functions such as active tracking, displayed distances and bearings.
A Web App for simplifying data access in the field (2026):
The above "web app" pulls maintenance reports, location and navigation data for local Public Land Corners (PLC) in Multnomah County. Inteneded as a mobile-optimized web application designed for field-use, navigation and maintenance of Multnomah County Public Land Corners. Replaces the spreadsheet system shared below. PLC numbers range from the 1000s to 2000s and not all numbers are used, for an example enter 1557 to see data on the "Willamette Stone." (2026)
Landscape Profile Rendering (2025):
Tracing the horizon: The above image shows a smokey landscape while the lower graphic illustrates the named peaks, their elevations and approximate distances from the same vantage. Demonstrating topographic visualization, viewshed analysis and cartographic labeling. Summer 2025
Maintaining the Public Land Survey System (PLSS) in the Columbia River Gorge National Scenic Area.
A Collaborative Document Resource for Improved Data Access (2024):
BT-I-310.pdfAbove is among the first Public Land Corner Maintenance Reports with my name on it.
Custom Google Sheet designed to streamline field staff workflows, integrating GPS data and asset mapping data retrieval. Replaced three ring binders, outdated Thomas Guides and handheld GPS units. Users input a Public Land Corner (PLC) number and the field relevant information is pulled. 2024
Asset Mapping and Project Tracking Samples Using Google Maps
(2020 - 2024):
A LiDAR Analysis Project (2020)
Looking for Giants (Yggdrasil in a Haystack):
Pictured above: One of the trees I sought in the Looking for Giants (Yggdrasil in a Haystack) project- some work samples shown below. The project was leveraging public LiDAR data to identify and protect old-growth habitats. I developed methods for tree crown delineation and 3D modeling to locate individual mature trees in dense canopy. 2020
From Looking for Giants (Yggdrasil in a Haystack): Above is a animated GIF showing visualized samples of Watershed Delineation, Canopy Height Modeling, Canopy Density Calculations, Tree Crown Delineation, Lidar Extraction & 3D Modelling. Fall 2020
