Introduction In this project, I completed a full ortho mapping workflow in ArcGIS Pro to create accurate satellite imagery products. The goal was to correct geometric distortion in raw satellite images so they can be reliably used for mapping, analysis, and measurement. This workflow included creating an ortho mapping workspace, performing block adjustment, adding ground control points, generating a digital

Most people think GIS is about making maps. In reality, the most valuable GIS work happens when spatial analysis supports real decisions. This lab focused on a practical problem faced by many communities: how to identify open-space parcels inside flood-prone areas that may qualify for FEMA Community Rating System (CRS) credits and potentially reduce flood insurance costs. What makes this
Introduction In a recent lab exercise, I worked with GeoDa, developed by the University of Chicago Center for Spatial Data Science, to examine spatial structure in geographic data. The objective was not simply to map values, but to determine whether patterns were statistically clustered, dispersed, or random. A map shows distribution. Spatial analysis tests whether that distribution has structure. What
Abstract This study examines the relationship between median rent in 2008 and the percentage of households with children in 2008 across New York City sub-boroughs. Exploratory spatial data analysis was conducted using GeoDa to assess the distribution of data, identify outliers, and evaluate statistical relationships among variables. Results indicate that median rent is positively skewed, while the percentage of households
Abstract This study examines the spatial distribution of Airbnb listings in Albany, New York, and evaluates their statistical clustering using the Getis-Ord Gi* local indicator of spatial association. Listing locations were aggregated into 8,000-foot hexagonal areal units to address spatial structure and mitigate point-level noise. A fixed distance band of 12,000 feet with row-standardized spatial weights was applied to identify
