GIS Specialist 1, Lead Service Line (LSL) Inventories Project, City of Guam, Guam, U.S.A. Aparajita is developing a comprehensive drinking water system materials inventory. She utilized client-specific standard templates (excel-based) and the ArcGIS web application tool to update records for both utility-owned and customer-owned portions of service lines. She was also responsible for reviewing existing GIS records to gather critical information, such as service line materials, sizes, and installation dates, which she then transferred into the designated columns of the inventory template, ensuring alignment with the latest client-specific requirements.

GIS Specialist 1, City of Hollywood Impervious Surface Area Digitization Project, City of Hollywood, Hollywood, Florida. Aparajita participated in the City of

Hollywood project, focusing on the digitization of impervious surfaces using ArcGIS Pro software. Her responsibilities included digitizing only the impervious surfaces within parcel boundaries and meticulously recording relevant attributes for both the impervious areas and the parcels themselves. After digitizing, she added the folio number from each parcel to the impervious surface feature class for accurate tracking.

She also verified parcels with no impervious surface cover. Cross-referencing the data with google street view, this work aimed to gather precise information for tax calculation purposes, supporting effective land management and urban planning initiatives.
