The Quezon City Government was honored with a Special Achievement in GIS (SAG) Award at the 2015 Esri International User Conference in San Diego, California, USA, for its Enhanced Tax Mapping Systems project called eTaxMaps.
The City Government was among 100,000 organizations around the world that went through the selection process, out of which only 100 merited the award.
"The SAG Awards identify the organizations and people who are using the power of geography to make our world a better place," says Esri president Jack Dangermond. "At Esri, we are always deeply inspired by the passion and innovation of our users. They deserve recognition for their invaluable contributions to their communities and the continued evolution of geographic science.”
The City Assessor’s Office and the QC Information Technology Development Office teamed up for the project. Quezon City’s “eTAXMAPS” aims to integrate and synchronize updating of Parcel Tax Maps vis a vis Land Tax records. Through this project, city officials, taxpayers, and property owners get a much better graphical overview of the overall tax situation of the city, through the use of geospatial technology and imageries. More particularly, it enhances capability for discovery, appraisal and assessment of undeclared, misclassified and unaccounted properties. This has resulted in a better system for cleansing of real property taxpayer data records through detection of inconsistencies in tax declaration, and a synchronized updating of these. The complexities in property index number (PIN) assignments and property location, comparing the existing tax maps with the QC real property assessment and taxation systems (QCRPATS) data base, were addressed.
The main goal of this project is to increase the operational efficiency for the City Assessor’s Office and thus enable the City Government to improve its tax base, producing more accurate estimates of the revenue potential in real property taxation.
Over 595,401 Real Property Units form Quezon City’s tax base. Statistics show more or less 288,450 parcels of land as of December, 2014; 272,265 parcels of which are taxable, with an estimated assessed value of Php44,239,453,790. Along with taxable improvements and machinery, the city’s total real property tax base amounts to Php 173,489,300,310.00, equivalent to Php 4,795,549,675.10 estimated annual tax due.

The City Government used ArcGIS (v.10.2) for Desktop and Server Licenses, and correlatively employing the use of ArcMap, ArcEditor applications. Part of the tangible output developed out of this project –apart from all the maps and lists– is the development of a Real Property Viewer Dashboard which is an application that allows users to view the location of parcels, and their corresponding attributes. This application was developed using ArcGIS 10 Web-Based Application Programming Interface (API), specifically, ArcGIS API for Flex and Application Builder for Flex.
The City Assessor’s parcel data is already being used by various Departments within the LGU as well as the Philippine Institute of Volcanology and Seismology (PHILVOCS), and can still be very useful in some other future projects of the city.
